The Best USB-C Battery Packs and Power Banks

After over 40 hours inquiring about 23 USB-C control banks and testing 14 of them, we found that the ZMI USB PD Backup Battery and Hub is the best choice to control any USB-C gadget when you’re far from an outlet: Its 45 W control yield can charge cell phones, tablets, and even workstations like the Apple MacBook Pro and Dell XPS 13. In the event that you have to charge just a USB-C– good telephone or tablet (yet not a PC) get the Tronsmart Presto 10400 mAh Type-C Battery Pack, which is littler and lighter yet will at present charge your apparatus speedier than comparative power banks that have just customary USB-A ports.

The quickest USB-C charging for any gadget

It fits preferable in a PC sack over a pocket, yet it’s the fastest power bank to energize, and it can charge everything from cell phones to workstations.




The ZMI USB PD Backup Battery and Hub can charge a USB-C– controlled PC—including a portion of our workstation picks, similar to the MacBook Pro, Dell XPS 13, or Asus Chromebook Flip—as quick as some other power bank, and it’s littler and lighter than the opposition. It has enough ability to completely charge most 13-inch PCs no less than one time or a cell phone five times or more. Also, when the power bank itself is depleted, it very well may be energized at about a similar speed, cutting hours off the time it should be connected to contrasted with the greater part of the opposition. It likewise has two USB-A ports for charging different gadgets—most contenders have just a single—and when you don’t have to charge, you can utilize the ZMI as a USB center point rather, sparing you the issue of requiring USB-C– to– A connectors for your mouse, streak drive, or camera.

  • Tronsmart Presto 10400 mAh Type-C Battery Pack

For USB-C cell phones and tablets as it were

The Presto is little enough to convey each day and equipped for charging most cell phones three times.




On the off chance that you don’t should have the capacity to charge a workstation, we suggest the Tronsmart Presto 10400 mAh Type-C Battery Pack. It offers enough ability to charge most cell phones three times, however it’s little and light enough to keep in your PC sack, knapsack, or satchel. Not at all like the greater part of its opposition, you can utilize the Presto’s USB-C port to charge the pack itself, making it speedier to energize and leaving the USB-A port open to all the while charge gadgets that don’t utilize USB-C.

What size would it be a good idea for you to get?

On the off chance that you have a USB-C– fueled workstation and need to charge it without chasing for an electrical plug, you ought to pick our bigger, PC prepared pick. In case you’re simply hoping to influence your USB-C cell phone or tablet, you can spare some cash (and some size and weight) by getting our cell phone pick.

USB-C battery attributes:

USB Type-C—or, all the more essentially, USB-C—is extremely simply the name of the port. Sort C ports can come in three fundamental power flavors, with progressively ground-breaking ports in reverse good with the less-intense flavors:

  • Legacy charging: up to 12 watts (2.4 amps/5 volts), the same as conventional USB-A.
  • Standard USB-C: up to 15 W (3 A/5 V), the regular most extreme for USB-C cell phones. Offers about 25 percent quicker charging than most USB-A chargers have utilized as of late.
  • USB-C Power Delivery: At minimum 30 W (2 A/15 V or 1.5 A/20 V), however up to 100 W—eight times quicker than latest USB-A chargers. Workstations require somewhere in the range of 30 W to just about 90 W of intensity, contingent upon the model, to charge at greatest speed; more current power banks can bolster 45 W charging, which will give a sensibly snappy charge to most moderate size PCs like a 13-inch MacBook Pro or Dell XPS 13 and will charge bigger ones, yet more gradually.

You have no motivation to purchase USB-C charging gear that works just at the slowest (inheritance charging) velocities, and makers have no motivation to continue making such models, other than saving money on advancement costs. So we didn’t consider any power banks constrained to inheritance charging—this guide centers around the other two flavors.

Why you should confide in us?

I’ve been expounding on batteries and electrical gadgets for Wirecutter for about three years, and in that time we’ve inventoried and considered in excess of 300 distinctive USB battery packs. Notwithstanding our own particular research and testing, we’ve worked with the battery testing and creation specialists at Cadex and had our testing featured on Good Morning America. We likewise connected with Total Phase, an organization that makes testing and advancement instruments for building and item firms, to enable us to watch that every one of our picks effectively actualize the USB-C convention. Add up to Phase USB item chief Chris Yokum gave us his organization’s USB Power Delivery Analyzer and helped us translate our outcomes utilizing Total Phase’s Data Center programming. (Despite the fact that in the past we looked into crafted by Benson Leung and Nathan K.— autonomous architects who have been trying USB-C item consistence—both have to a great extent quit distributing new test outcomes and haven’t posted any audits of USB-C control banks.)

How we picked and tried?

We’re continually watchful for new USB-C– able battery packs, filtering significant retailers, for example, Amazon and Best Buy and remaining over innovation news. In spite of the fact that there are unlimited choices for control manages an account with standard USB-A ports—the kind we’ve all utilized for a considerable length of time—there are far less power saves money with USB-C ports to look over (and even less great alternatives). To locate the best ones, we utilized the accompanying criteria:

Charging speed (control yield)

  • What we search for:
  1. 15 W charging for cell phones and tablets
  2. 45 W Power Delivery (PD) charging for PCs

Why it makes a difference:

  • More watts implies your gadget will charge quicker and the power bank will be good with a more extensive scope of gadgets.

How we tried:

A decent power bank will charge your telephone or PC as quick as would be prudent, yet an incredible power bank will likewise do it as per rules set by gauges gatherings.

To test both speed and adherence to specialized principles, we associated each Power Delivery control bank to a little test gadget that let us screen every one of the signs being passed forward and backward along the USB-C link and after that to an Apple 13-inch MacBook Pro with Touch Bar that required charging.

For the Power Delivery control banks expected to charge just cell phones and tablets, we utilized a USB programmable load that let us reliably draw indistinguishable measure of intensity from a genuine cell phone would. We needed to see an entire 15 W accessible, or 5 V/3 A. Some USB-C chargers still utilize the charging levels of heritage USB-A ports, which are around 30 percent slower—a discernible drop in case you’re acclimated with a telephone fit for charging quicker.

For control banks intended to charge PCs, we searched for a base yield of 45 W. No more to rapidly charge most 13-inch PCs and gradually charge a workstation that needs 80 W—a 20 W or 30 W control bank will charge even a littler PC all the more gradually. (There are no power banks yet that can give the 100 W greatest that the PD standard takes into consideration—45 W is what’s right now accessible. You should search for 45 W currently to ensure the power bank will remain valuable regardless of whether you redesign your workstation.)

With our Power Delivery Analyzer and Data Center programming, we could see every one of the messages that the power bank sends forward and backward to arrange the power level. We expelled all brand IDs from the reports to stay away from any inclination and had Chris Yokum, the USB item supervisor at Total Phase, investigate check whether there were any warnings in how the power banks set up the association. We additionally took a gander at the power level the gadgets at last got from the power bank and whether that power level was steady or fluctuating. In the event that a battery pack gives fluctuating force, it could imply that the battery is made with inferior segments or a not as much as perfect plan, and it could at last lessen the life of the gadgets you’re charging.

Energizing velocity (control input)

What we search for:

  • 15 W reviving for littler, cell phone centered power banks
  • 30 W reviving for bigger, workstation centered power banks

Why it is important:

  • Higher power input (more watts) will energize your battery speedier, cutting the time by 30 percent or more, which is convenient when you’re voyaging or generally have constrained time to stop at an outlet.

How we tried:

How quick a battery charges a gadget is our best concern, yet how quick it revives itself is nearly as essential—extensive batteries can set aside a long opportunity to energize, and a large portion of us have had times when we’ve neglected to charge a power bank and need to top it off as quick as could be expected under the circumstances. A decent USB-C battery pack utilizes Type-C ports for both info and yield; some less expensive models still depend on Micro-USB contributions to energize the pack, however those past age ports charge around 25 percent slower than standard USB-C ports. We rejected those models without testing.

We additionally required greater packs to charge at the quicker Power Delivery speeds. For gigantic batteries like those made for charging a workstation, the distinction that PD charging offers can be huge: A 92 Wh (25,000 mAh) battery—enough to completely charge a 13-inch PC—would take over 10 hours to charge without PD, however can top off in as few as four hours with PD. (To exploit USB-C PD speeds when refilling the power bank, you should utilize a USB-C PD charger. On the off chance that you don’t possess one as of now, we have a manual for the best USB-C PC chargers.)

To test control input, we began with a completely depleted battery pack, connected it to a rapid USB-C charger, and checked the power level with the Power Delivery Analyzer. Since these gadgets tend to pull the most power when they’re at their least charge, we began with the pack’s battery level at zero to test the furthest reaches of the power input. We additionally observed the temperature of the battery: Most likewise get somewhat warm while charging, yet unnecessary warmth—enough to make the unit awkward to the touch—would be a notice sign that something isn’t right with either the specific pack or the outline.


What we search for:

  • Tried limits that are in accordance with producer’s cases
  • Littler power banks: at least two charges for a normal cell phone
  • Bigger power banks: no less than one full charge to most 13-inch PCs

Why it is important:

  • The bigger the power bank’s ability, the more occasions it can energize your gadgets

How we tried:

Since some power is constantly lost while changing over between a battery’s voltage and the voltage need to charge a gadget, no battery pack will give 100 percent of its promoted limit as charging power—an awesome one can get more than 95 percent of that limit, and great one has around 90 percent. All things considered, the distinctions are so infinitesimal, and there are such a significant number of factors that will influence the outcomes you get at home—the surrounding temperature, how frequently you’ve charged the power bank, the amount you last charged it and at what speed, for instance—that you shouldn’t fuss over a couple of rate focuses all over. Our tests would need to demonstrate 85 percent or less of promoted limit before we’d stress over any variety.

To ensure that our test assemble didn’t have any duds or configuration defects, we tried every battery’s ability three times and arrived at the midpoint of the outcomes. Each time, we completely charged the battery as quick as it could go and after that released it at a consistent 5 W (1 A/5 V) over USB-A. That is slower than most present day gadgets charge, yet this approach guaranteed that we would get a steady draw amid the entire procedure and have results that were sufficiently precise to look at.

We likewise utilize this limit test as the reason for different measurements. All else being equivalent, better power banks will have higher limit in respect to cost, and a few batteries hold more vitality than different models with about a similar size or shape.

Design and features

What we search for:

  • Conservative plan
  • Simple to-peruse battery checks
  • Basic power catches and controls
  • No less than one USB-C port and one USB-A port

Why it makes a difference:

  • On the off chance that a power bank is anything but difficult to utilize and simple to convey, you’re more averse to abandon it on a rack and more inclined to have it when you require it.

How we tried:

Power banks intended to charge cell phones in a hurry shouldn’t be excessively massive or bulky. In the event that you wear garments with bigger pockets, you ought to have the capacity to convey our versatile pick without a sack. In case you’re screwed over thanks to undersized pockets, or none by any means, our pick ought to be anything but difficult to fit into a little sack, grasp, or handbag. Little size is to a lesser extent an essential worry for a workstation charging power bank, since you’re probably going to convey it in a PC pack, rucksack, or attaché, however we took a gander at the heaviness of these bigger power banks and support ones that are quite lighter.

At the season of our testing, even the best power banks accessible have only a solitary USB-C port, so we required no less than one USB-A port too, regardless of whether to charge a second gadget or to utilize a more seasoned link after all other options have been exhausted.

Despite the fact that battery checks can be untrustworthy—numerous elements that effect precisely how much vitality stays in a battery are continually changing—the best power banks utilize an advanced measure that shows remaining vitality as a rate. We lean toward this approach, however in the event that a battery rather utilizes a little line of LEDs as a power meter, more LEDs implies better precision.

Warranty, Service, and Extras

What we search for:

  • A base year guarantee
  • Client benefit reaction in under multi day (extra focuses for telephone bolster)
  • Quality links, chargers, or cases incorporated into the container

Why it makes a difference:

  • On the off chance that any one a player in a power bank comes up short—the charging ports quit working, the battery won’t hold a charge, the info control port comes up short—the part can render the entire thing pointless. A guarantee and responsive client benefit include genuine esteem if something turns out badly. Helpful extras are only a decent reward.

How we tried:

USB-C battery packs should accompany a guarantee of no less than a year, and the guarantee should be one that you can really utilize—batteries can and do fizzle. Top brands, including Anker, Jackery, and RAVPower have been around for some time and have a strong notoriety. When we considered or tried a battery from a more up to date mark, we additionally namelessly reached the organization’s client benefit (by means of telephone or email) to ensure that it was responsive and that the organization would remain behind its items.

All in all, we decide the best battery packs in light of how they perform in our tests, not by what treats come in the case. Be that as it may, some of the time those treats are incredible sudden death rounds. At the point when a battery pack ships with outstandingly high caliber or additional long links, port connectors, or a divider charger, we calculated those things into the general estimation of the bundle.

A ground-breaking, workstation prepared pick: ZMI USB PD Backup Battery and Hub

  • ZMI USB PD Backup Battery and Hub

The quickest USB-C charging for any gadget

It fits preferable in a workstation sack over a pocket, yet it’s the fastest power bank to revive, and it can charge everything from cell phones to PCs.




The ZMI USB PD Backup Battery and Hub is the speediest and most flexible power bank for those occasions when you have to energize and you’re not close to an outlet. It charges workstations, tablets, and cell phones at indistinguishable speed from the opposition, yet it can energize itself speedier and has more USB-A ports than whatever else we tried. A one of a kind and valuable liven is that it can work as a USB center point when associated with a PC’s USB-C port, giving you a chance to connect to streak drives, cameras, or even printers to the battery’s USB-A ports.

Every one of the three of the 45 W control banks we tried could charge a MacBook Pro as quick as any power bank presently accessible, however the ZMI has a couple of preferences that causes it charge different gadgets quicker, as well. Notwithstanding its single USB-C port, the power bank incorporates two conventional USB-A ports, both of which can charge gadgets at the full 12 W that port generally permits, or up to 18 W for any gadget perfect with Quick Charge 3.0. Since bigger batteries like the ZMI are best to charge outfit when far from your work area or voyaging, the additional quick charging ports make our pick more flexible whenever you’re conveying in excess of one gadget that requirements control. Similarly as with the other PD-able models we tried, the ZMI brought no warnings up in our security tests, and it effectively charged every one of the gadgets that we attempted to accuse of it.

USB-C charging levels of normal workstations

As far as charging the battery itself, our pick and another model we tried, the Jackery Titan X, can both energize at up to 45 W; another contender, the Dodocool control bank, can revive at just 30 W. The additional 15 W makes our pick just shy of 50 percent speedier to finish off when your battery is dead and you have to leave the wellbeing of a divider outlet behind.

In the previous couple of long stretches of intensity bank testing, we’ve discovered that most batteries have around 90 percent of their publicized limit accessible. That remained constant for the majority of the USB-C control banks we tried for this guide, including our best pick. The ZMI control bank has enough vitality ability to charge a 13-inch workstation like an Apple MacBook Pro or Dell XPS 13 once and still charge a telephone like a Samsung Galaxy S8 or Apple iPhone 8 twice. In case you’re simply charging cell phones, you’ll get significantly more from it: around six full charges for telephones like the Samsung Galaxy S9 or Apple iPhone X.

The general plan of the ZMI USB PD Backup Battery is likewise somewhat more pleasant than that of the opposition. In spite of its gigantic limit, the ZMI doesn’t feel significantly greater than any medium-sized USB control bank. At 6¼ inches in length, 3¼ inches wide, and about ¾ inch thick, it’s too enormous to easily convey in a pocket—even a liberally measured one. In any case, it’s light enough—at only 14.3 ounces, it’s discernibly and impressively lighter than the opposition—to add to any PC pack, portfolio, or even most handbags bigger than a grasp.

On the off chance that you twofold tap the power catch in favor of the ZMI control bank, a blue light turns on and the power bank works as a USB center—but one with slower USB 2.0 information exchange speeds—when you associate it by means of USB-C to a workstation. This element will be particularly valuable on the off chance that you have one of the developing number of USB-C fueled PCs that have dumped USB-A ports totally—you won’t need to convey connectors to connect to a mouse, versatile hard drive, or glimmer drive. The power bank can’t charge your PC when it’s in center mode, so you need to pick either. In any case, it’s an element that no other power bank offers and it can eliminate what number of knick-knacks you have to make sure to carry with you.

This is the primary ZMI control bank we’ve suggested, yet ZMI is the charging brand of Xiaomi, which has been producing chargers, links, and frill since 2010. The organization offers a 18-month guarantee on this power bank, which is in accordance with other significant brands. Most client bolster is by means of email, however you can call the organization amid business hours to investigate issues. We don’t confide in ZMI’s suspiciously great (at the season of production) Amazon client audits, which rate just a “C” on Fakespot’s trust-checking motor. Be that as it may, the pack did well in the entirety of our tests, and other expert commentators, including Macworld’s Glenn Fleishman (a previous Wirecutter contributing editorial manager) likewise give the pack high marks.

Flaws yet not dealbreakers

At 20,000 mAh (or 74 Wh), the ZMI USB PD Backup Battery and Hub has a great deal of vitality limit, yet the main sign of its charge level is a four-LED battery meter, where each portion is about 25 percent of the battery. Since the limit is large to the point, that leaves a great deal of speculating about the genuine charge spoken to by some random LED. The Jackery Titan X utilizes a substantially more accommodating advanced show, and our past Anker pick utilized a 10-section LED that offered more exactness than the ZMI’s LEDs.

Regardless of having the capacity to energize at to 45 W from a PD-able divider charger, our pick doesn’t really incorporate a divider charger. Contrasted with influence banks that do incorporate a PD charger, the ZMI is shoddy enough to get one independently and still set aside extra cash, yet in the event that you don’t as of now have a USB-C PD divider charger at home, you won’t have the capacity to exploit this power bank’s quicker reviving. We have a manual for the best USB-C chargers with a couple of various choices.

Our pick for cell phones: Tronsmart Presto 10400 mAh

  • Tronsmart Presto 10400 mAh Type-C Battery Pack

For USB-C cell phones and tablets as it were

The Presto is little enough to convey each day and fit for charging most cell phones three times.




We’re as of now testing a couple of new USB-C control banks that are gone for keeping telephones and tablets charged. We’ll refresh this guide when our outcomes are prepared, yet until the point when we locate a superior pack, we think the Tronsmart Presto 10400 mAh Type-C Battery Pack is the best alternative for a USB-C battery that you can convey with you all over. Both of its ports—one USB-C and one USB-A—will charge your cell phones as quick as could reasonably be expected; and when it comes time to energize the pack itself, you do as such finished USB-C, so the Presto revives quicker than packs with a Micro-USB input. The battery won’t be agreeable in many pockets, however it’s little enough and light enough for any PC pack, knapsack, or tote, and it has enough capacity to charge most tablets more than once and most telephones a few times over.

Like all the best batteries, the Tronsmart Presto has one USB-C port and one USB-A port, and both will charge perfect gadgets as quick as those gauges permit. That implies USB-C gadgets will energize at to 15 W, QC 3.0 gadgets will energize at to 18 W, and standard USB gadgets will energize at to 12 W. A few makers are making USB-C packs (like this one from JTD) that put out as a rule as much power as customary USB; there’s no point paying additional for a battery with USB-C in the event that it doesn’t exploit the additional power accessible.

The best USB-C battery packs additionally energize themselves through their USB-C ports, and the Presto does as such as quick as standard USB-C is competent—once more, 15 W. Less expensive packs flooding Amazon publicize USB-C ports yet at the same time depend on Micro-USB ports for reviving. That implies you’d need to convey an additional link for reviving and sit tight longer for that charge, since Micro-USB ports are by and large around 25 percent slower.

The Presto can charge most cell phones three times or most tablets once. This is a decent limit with regards to a great many people, since it keeps the pack little and light enough to convey each day. The main packs we’ve tried that rival the Presto need rapid charging and USB-C energizing or originate from organizations without client bolster. We’re at present testing some new power banks that may rival the Presto, however until the point when that testing is done, the Presto’s size and limit make it the best alternative for quick, versatile USB-C charging.

In our tests, the Presto conveyed control not surprisingly under USB-C rules, so any benchmarks consistent gadget ought to be protected when connected to it. We charged a MacBook Pro to check how the Presto handles charging a gadget more intense than proposed, at that point a USB-C gadget, at that point a USB stack analyzer set to zero present, all while utilizing the included USB-C– to– C link. Each time, the Presto conveyed indistinguishable power from mark name divider chargers we knew to be dependable without varieties in voltage or amperage.

The Presto is generally the extent of two decks of playing cards end to end; it’s about a similar six inches in length as our best pick from ZMI, however as a rule around 66% as wide and considerably lighter. The Presto’s size and shape are unpretentious in even a little sack, however it’s a bit too long to keep in many pockets.

The pack’s USB-C– in/out port and USB-A– out port are toward one side, and you tap a little catch set flush at the edge to begin charging your gadget or to illuminate the four-LED limit check along the best.

To test Tronsmart’s client benefit reaction time, we namelessly messaged the organization’s email-just help with an issue. A delegate reacted five hours after the fact with some investigating tips and guidelines for how to start a trade in the event that we couldn’t resolve our concern. While telephone bolster is dependably an or more, Tronsmart’s provoke and definite email bolster left us feeling positive about our pick.

What to anticipate

Versatile battery packs are still transcendently USB-A, however we’re at present testing three more USB-C models: the RAVPower Portable Charger with USB Type-C, Jackery Bolt-C, and Eeco 10000 USB-C QC Portable Charger.

The Indiegogo-upheld Lifepowr A3 is the main USB-C PD battery pack we are aware of that guarantees to surpass the 45 W yield of our best pick—the producers of this unreleased model claim that it will bolster the full 100 W conceivable under the USB-C PD standard. Be that as it may, regardless it hasn’t delivered notwithstanding introductory guarantees of 2017 accessibility, and the normal retail cost of $300 is cosmic.

Flying with batteries

In spite of the fact that the majority of us would consider USB battery packs to be close to home electronic gadgets, you ought to accept that transportation experts will see the pack as an extra battery and subject it to increasingly stringent guidelines. For instance, the FAA enables travelers to acquire save batteries lightweight packs yet not in processed gear. (On the off chance that you have to door check an arranged lightweight suitcase, you are legitimately required to move any lithium-particle batteries from that sack to your genuine go ahead.) There is no restriction to the quantity of batteries you can convey for individual utilize, insofar as every ha a limit of 100 watt-hours or less. Every one of the batteries we investigated for this guide have limits that fall underneath that edge.

The rivalry

PD-skilled charging for workstations

Our past best pick, the Anker PowerCore+ 26800 PD (with charger), and its fundamental adversary, the RAVPower 26800 PD Portable Charger are restricted to 30 W charging. Since more up to date contenders, including our best pick, are able to do quicker and that’s just the beginning adaptable 45 W charging at comparative or lower costs, we expelled both these power banks in our latest refresh.

The Jackery Titan X Supercharge (divider charger) offers the same 45 W charging and reviving of our best pick and includes a battery check that demonstrates the level of charge staying rather than a meter made of a couple of little LEDs. Be that as it may, the Titan X has only one extra USB-A port contrasted with two for our best pick. Likewise, despite the fact that the publicized limit of the Titan X is more than 30 percent more than our best pick’s, our tests estimated generally the same usable limit.

Like our best pick, the Dodocool 20100 45 W PD Portable Charger can charge PD-competent workstations at up to 45 W and has two extra USB-A ports. In any case, when the Dodocool pack is depleted, it will energize at in general up to 30 W, making it around 50 percent slower than our best pick.

In spite of the fact that it’s one of the main USB-C PD control banks accessible at Apple stores, we expelled the Mophie Powerstation USB-C XXL without testing it. Its charging and reviving is restricted to 30 W, contrasted with 45 W for our best pick, and its cost is significantly higher with no additional highlights to legitimize the cost.

Standard USB-C charging for cell phones

The Jackery Titan S was one of the primary USB-C battery packs accessible from a confided in maker, yet it bolsters just the slower portable cordial velocities of our pick from Tronsmart.

The Tylt Flipstick is a standout amongst the most pocketable USB-C packs accessible, however we didn’t test it since it’s hamstrung by especially moderate yield: At 5 W (1 A/5 V), the Flipstick will charge a gadget at as a rule a large portion of the speed of inheritance USB chargers.

The Vinsic 20000 mAh Power Bank is a substantial pack like our best pick from ZMI, however it offers just the cell phone yield of our littler pick from Tronsmart.

We expelled the Lovphone PowerCore 10000, the Orico USB-C 10000 mAh Portable External Battery, and the JTD Type-C 10000 mAh Portable External Battery without testing due to moderate, heritage charging speeds from their USB-C ports.
