Whether you name them battery packs, power banks or transportable chargers, these equipment do one factor effectively: cost units when you possibly can’t discover an open outlet. Small sufficient to slot in a day pack and durable sufficient to stay on the backside of your stick with it, battery packs can cost your smartphone, pill, laptop computer and even all three directly, relying on the scale of the battery. What measurement you’ll want, and any additional options you might discover helpful, will largely depend upon the units you propose on charging up. With so many choices in the marketplace proper now, we examined out a bunch of fashions to find out the best transportable power banks you may get proper now.
What to look for in a conveyable battery pack
Battery sort
Nearly each rechargeable power financial institution you should purchase (and most transportable units) comprise a lithium-ion battery. These beat different present battery sorts when it comes to size-to-charge capability, and have even elevated in power density by eight fold prior to now 14 years. They additionally don’t endure from a reminiscence impact (the place battery life deteriorates on account of partial fees).
One disadvantage you’ll have heard is the opportunity of lithium ion batteries catching hearth. To restrict the hazard, battery packs require inside mechanisms to restrict issues like voltage and strain. While you must nonetheless make certain a battery isn’t uncovered to pointless stress like extreme warmth, harm from drops or working in freezing climate, battery packs are thought of secure sufficient to convey on an airplane. According to the TSA, exterior batteries rated at 100Wh or much less (which all of our suggestions are) can fly with you – simply ensure you stash them in your stick with it as they aren’t allowed in checked baggage.
Capacity
Power financial institution producers nearly at all times record a battery’s capability in milliamp hours, or mAh. Smaller batteries, say these that may cost a smartphone to between 50 and 75 %, are inclined to have a 5,000mAh capability. Larger batteries that may recharge laptops and tablets, or give telephones a number of fees, can exceed 25,000mAh. Unsurprisingly, the costs on most batteries goes up as capability will increase, and since batteries are bodily storage items, measurement and weight go up with capability as effectively. If you need extra power, be ready to spend extra and carry round a heavier brick.
You may assume {that a} 10,000mAh power financial institution may cost a 5,000mAh telephone to 100% twice, however that’s not the case. In addition to easy power loss by way of warmth dissipation, components like voltage conversion additionally convey down the quantity of juice that makes it into your telephone. Most producers record what number of fees a battery can provide a sure smartphone. In our exams, 10,000mAh of battery pack capability translated to roughly 5,800mAh of system cost. 20,000mAh chargers delivered round 11,250mAh to a tool, and 25,000mAh banks translated to about 16,200mAh of cost. That’s a median effectivity charge of round 60 %.
Ports
While the tech world is (fortunately) transferring in the direction of USB-C as the usual, it’s nonetheless a combined bag within the power financial institution world. All of our picks have not less than one USB-C port and some even have a USB-A port or two. Newer Android smartphones cost through USB-C, iPhones nonetheless use the Lightning port, however the newest tablets (together with present technology iPads) and newer laptops are sometimes powered up through USB-C.
When a battery pack has multiple charging port, they normally serve completely different capabilities. You’ll sometimes see not less than one port labeled “in/out,” which implies you need to use it to each cost the financial institution and cost your system. While USB-A ports can power up smartphones and different small units, they will’t cost bigger units. Plus, they aren’t as quick as USB-C ports general. That’s one thing to bear in mind while you’re deciding which ports and cables to make use of to attach your telephone to the pack.
There’s much more variation amongst USB-C ports themselves, with completely different ports on the identical system supporting completely different power switch charges. What meaning in sensible phrases is an iPhone will cost simply tremendous plugged right into a power financial institution’s 18W port. But to correctly cost, say, a MacBook or comparable laptop computer, it’ll want the additional juice provided by a 100W port (which bigger power banks can provide). Power banks with multiple port may cost a number of units on the similar time, however speeds and the general cost delivered might be decrease.
You’ll additionally wish to contemplate your cable. For something bigger than a smartphone (and to entry fast-charging capabilities) you’ll wish to use USB-C ports and cables. But not all cables are created equal, even once they have the identical USB-C plugs on the top. If you need power delivered from a 100W USB-C power financial institution port, you’ll want a 100W-rated USB-C cable. Luckily, power banks able to delivering 100W have a tendency to incorporate a appropriate cable. For any units that don’t, we’ve tried and favored Anker’s 100W USB-C cable. For smaller units, we used this 60W cable from Nimble and we don’t suggest bothering with cables beneath 60W. For round $20, higher-capacity cables will ensure you’re not losing time with connections that restrict your potential power switch.
Design
For probably the most half, battery packs have a squared-off, brick-like design, although many nod in the direction of aesthetics with enticing finishes and detailing. While that doesn’t have an effect on how they carry out, it’s a consideration for one thing you’ll work together with frequently. Some transportable power stations embrace additional options like MagProtected compatibility, a built-in wall plug or perhaps a kickstand. Nearly all have some type of indicator to let you know the way a lot accessible cost your power financial institution has left, normally expressed with lighted pips close to the power button. Some of the most important banks take {that a} step additional with an LED show indicating a share for the remaining battery, which may be useful for those who’re counting on a pack in a cell workplace setting or one thing comparable.
How we examined
Before we even put our arms on a battery pack, we did intensive analysis. We thought of manufacturers Engadget reviewers and workers have tried over time and we checked out buyer scores on retail websites like Amazon and Best Buy. In all, we acquired 14 battery packs, starting from small wi-fi banks to massive, multi-device batteries.
Here’s the total record:
MagProtected-compatible
Apple MagProtected Battery Pack (5000 mAh)
Spigen ArcHybrid Mag (5000mAh)
Anker 521 Magnetic Battery (5000 mAh)
Anker 633 Magnetic Battery (10,000mAh)
Low capability (≤10,000mAh)
Anker 511 Power Bank (5,000 mAh)
Anker 313 Power Bank (10,000mAh)
Nimble Champ (10,000mAh)
Biolite Charge 40 PD (10,000mAh)
Mid capability (10,001 – 20,000mAh)
Otterbox Fast Charge (15,000mAh)
Mophie Powerstation Pro (20,000mAh)
Anker 535 PowerCore 20K (20,000mAh)
Nestout Portable Charger (15,000mAh)
High capability (20,001mAh+)
Mophie Powerstation Pro XL (25,000mAh)
Anker 737 Power Bank (25,600 mAh)
Zendure Supertank Pro (26,800mAh)
We regularly replace this information as firms launch new merchandise, which implies we have now completely different units available for testing. For this information, we examined every battery with some mixture of an iPhone 14 Plus, an iPhone 11, a Samsung Galaxy S22 Ultra and a Fifth-gen iPad Air. I charged one system at a time, despite the fact that some packs are able to multiple-device charging. I charged the telephones or pill from absolutely depleted to 100% (or till the power financial institution was lifeless), and didn’t use the system whereas they charged apart from to power them on and enter the unlock code.
I used the cable included with every power financial institution to cost the Galaxy S22 Ultra and the iPad Air. For the iPhones, I used the USB-C to Lighting cable that Apple gives. In the case of the lower-capacity power banks that didn’t embrace a wire or included one with USB-C to USB-A connectors, I used this 60W-rated USB-C to USB-C cable.
For reference, listed below are the battery capacities of every system we used for testing:
iPhone 11: 3,110 mAh
iPhone 14 Plus: 4,325 mAh
Galaxy S22 Ultra: 4,855mAh
iPad Air: 7,729mAh.
I famous the instances for every cost and the variety of fees every financial institution offered. I additionally paid consideration to issues like ease of use and general design. Here’s what made the lower for best transportable chargers:
Best MagProtected-compatible battery: Spigen ArcHybrid Mag
I went into this class anticipating Apple’s personal MagProtected battery pack to be a prime choose. And whereas it carried out admirably, charging a lifeless 14 Plus to about 43 % in an hour and 45 minutes, Spigen’s ArcHybrid delivered a 56 % cost in almost the identical period of time. The ArcHybrid firmly attaches to the MagProtected ring and it’s flush sufficient you could simply maintain your telephone and use it whereas charging up. Unlike the Apple battery, it consists of 4 indicator lights that can assist you gauge how a lot juice the pack itself has left. Considering Spigen’s battery is $30 cheaper than Apple’s, it’s straightforward to suggest.
Alternatively, Anker’s 633 Magnetic battery delivered a bigger cost because of its 10,000mAh capability, boosting the iPhone to 100% in three hours with sufficient left over for a further 29 % cost. And whereas the kickstand characteristic felt mildly helpful, the battery itself was cumbersome – however that’s comprehensible for a power financial institution that’s twice as massive as Spigen’s. Ultimately, the ArcHybrid carried out higher as a fast and handy method to give a partial cost to your iPhone on the go.
It’s essential to notice that wi-fi charging is much less environment friendly than wired. Our exams confirmed wired battery banks ship a tool cost at round 60 % effectivity. With the wi-fi chargers, that charge dropped to a median of 46 %. Something to bear in mind when weighing the prices, each ecological and financial, of wasted power.
Specs: 5000mAh, 7.5W max
Ports: One USB-C in/out
Cable: USB-C to USB-C
Number of fees iPhone: 0.56
Charge time iPhone: 0 to 56% in 1h 43m
Best battery for a partial cost on an Android: Anker 511 Power Bank
Until Android telephones get one thing like MagProtected, a wired connection makes probably the most sense for on-the-go fees. The Anker 511 Power Bank is a cleverly designed unit in regards to the measurement and form of a slim stick of butter. The battery has sufficient capability to cost a depleted Galaxy S22 Ultra to 75 % in somewhat over an hour, so that you’ll be coated for those who don’t have lengthy between flights to provide your telephone a bit extra juice. It additionally has a built-in plug and permits for pass-through charging, which implies it may act as a wall adapter for those who’re ever caught with each a lifeless battery financial institution and telephone, however occur to be close to an outlet. It doesn’t include a cable, although, so that you’ll want to offer one that may go from the financial institution’s single USB-C port to your system.
Specs: 5,000 mAh, 10W max
Ports: One USB-C and wall outlet prongs
Cable: None
Number of fees Galaxy S22 Ultra: 0.75
Charge time Galaxy: 0 to 75% in 1h 7m
Best low capability battery: BioLite Charge 40 PD
BioLite might be higher identified within the out of doors neighborhood than the tech world, and it’s truthful to say that the Charge 40 PD is geared extra in the direction of tenting journeys than city commutes. But this battery merely outperformed the others in its class. The rugged, yellow-accented exterior is a refreshing change from the usual shiny black of many tech equipment. It additionally has a rubberized end and feels stable sufficient to deal with the bumps and jolts of using round in a handbag or messenger bag all day. It gave each the iPhone and the Galaxy one and a half fees, which implies it’s a lot able to reviving a lifeless telephone a few instances while you’re out and about.
The Nimble Champ will get an honorary point out right here as a result of it’ll additionally ship a couple of dependable fill-ups and is available in a rugged bundle. It delivered a full cost to the iPhone in two hours plus a 22 % cost in 16 minutes. It gave the Galaxy a full cost in an hour and 44 minutes, then bought the telephone from lifeless to 41 % in 50 minutes. At the identical $60 worth level because the BioLite, Nimble will get additional factors for being one of many few B-Corp-certified private tech producers on the market, that means they’ve dedicated themselves to larger environmental and social requirements, and took the time to show it by way of B Lab’s certification course of.
Specs: 10,000mAh, 18W max
Ports: One in/out USB-C, two USB-A out solely
Cable: USB-C to USB-A
Number of fees iPhone 14 Plus: 1.36
Charge time iPhone: 0 to 100% in 1h 50m, 0 to 50% in 36m
Number of fees Galaxy S22 Ultra: 1.33
Charge time Galaxy: 0 to 100% in 1h 33m, 0 to 50% in 45m
Best medium capability battery: Otterbox Fast Charge
At the medium-capacity degree, you possibly can cost a number of units directly or power up one thing bigger than a telephone. The Otterbox Fast Charge power financial institution solely lists 15,000mAh of capability, however it carried out almost in addition to the 20,000mAh batteries whereas costing about $30 much less. Over the month and a half I spent testing battery packs, this was the unit I grabbed probably the most when my very own units wanted a cost. It has a classy exterior with a grey fake leather-based end and copper detailing. Slightly larger than a deck of playing cards and weighing simply over 11 ounces, it’s a pleasant wanting accent that feels stable.
It stuffed up each smartphones twice, then gave a further third of a cost every. I launched the iPad to the combination right here and bought a full cost plus an additional third. The Otterbox additionally misplaced little or no battery power whereas sitting dormant, which implies for those who carry it round on the off probability that you simply’ll want it, it ought to have loads of power when the time comes.
This class might have been the closest to name, as Anker’s 535 Power Core carried out barely higher than the Otterbox, however Anker’s worth level is larger. That stated, if you’d like a screaming fast cost for your Galaxy telephone, seize the 535. It bought the Galaxy as much as 100% 3 times, taking about an hour every time. It had sufficient left over for a small nine-percent cost earlier than it lastly gave up. While the battery did get fairly heat, it by no means felt overly scorching. That one-hour refill is the quickest any power financial institution was in a position to ship a cost to the Galaxy, apart from Anker’s 737, which shaved off a couple of minutes, however prices $90 extra. I additionally appreciated the 535’s cool iridescent end.
Update, 2/13/2023: Anker’s 535 Power Core battery, which we talked about as an alternate medium-capacity choice, has been recalled on account of a possible hearth hazard. If you have bought the 535 battery pack, the Anker rep we spoke with advisable that you simply cease utilizing the system and comply with the rules from the EPA or native companies to get rid of the battery. Follow this hyperlink to learn to provoke a refund.
Specs: 15,000mAh, 18W max
Ports: One in/out USB-C, one in/out USB-A
Cable: USB-C to USB-A
Number of fees iPhone 14 Plus: 2.33
Charge time iPhone: 0 to 100% in 2h 2m common, and 0% to 33% in 27m
Number of fees Galaxy S22 Ultra: 2.33
Charge time Galaxy: 0 to 100% in 1h 35m and 0 to 37% in 33m
Number of fees iPad Air: 1.31
Charge time iPad: 0 to 100% in 2h 23m and 0% to 31% in 38m
Best excessive capability battery: Anker 737 Power Bank
If you need one thing with loads of cost that transfers rapidly, go for the Anker 737 Power Bank. It was for probably the most half the quickest financial institution we tried, able to delivering the most important quantity of cost within the shortest time frame for the iPad and Galaxy. (Anker’s 535 bought the iPhone to 100% a median of two minutes quicker, however didn’t give as many fees.) The 737 absolutely charged our S22 Ultra 3 times, with sufficient power left over for one other 93 % cost – and people full fees accomplished in beneath an hour on common. That’s on par with wall charging. The numbers for the iPhone have been barely much less staggering, however nonetheless spectacular, going from zero to full in about an hour and a half. The iPad charged fully twice, and did so in simply over two hours, which can be near that system’s wall-connected cost speeds.
While it’s nice for a number of full fees on a given smartphone, I ought to level out that the 737 has three ports, however solely a kind of is USB-C. If you wish to cost multiple system at a time, you’ll have to make use of the lower-efficiency USB-A ports for a few them. That stated, this financial institution not solely prices lower than the opposite excessive capability batteries we tried, it additionally features a 65W PowerPort quick charger, which fits for $34 by itself.
The design is nothing groundbreaking, with a shiny black exterior and a metallic-looking end on one facet. It weighs somewhat over a pound and has the identical basic type as an old-fashioned TI-85 graphing calculator. Its single button has eight lighted pips to indicate you the way a lot cost it has left.
Specs: 25,600mAh, 60W max
Ports: One in/out USB-C, two out solely USB-A
Cable: USB-C to USB-C, consists of 65W wall adapter
Number of fees iPhone 14 Plus: 3.67

Number of fees Galaxy S22 Ultra: 3.93
Charge time Galaxy: 0 to 100% in 57m common 0 to 93% in 59m
Number of fees iPad Air: 2.14
Charge time iPad: 0 to 100% in 2h 7m common and 0 to 14% in 13m
Best cell command middle battery: Mophie Powerstation Pro XL
For those that take their work on the street, the Mophie Powerstation Pro XL, with its trio of USB-C ports, is an efficient choose. It’s able to charging three devices directly, with a distinct wattage ranking for every port: 100W, 45W and 20W. In apply, meaning you possibly can use the ports to cost a laptop computer, a pill and a telephone concurrently. To hold the numbers comparable throughout our testing, I charged one system at a time. Both smartphones juiced up absolutely 3 times, with round a 3rd of a further cost left over. I bought about two full fees from the battery on the iPad Air.
The Powerstation XL has the appear and feel of a elaborate pocketbook with a marled grey cloth exterior that feels good within the hand and, by the way, hides stains effectively. It weighs the identical because the Anker 737 (one pound and three ounces) and in addition has lighted pips to point cost ranges. There are solely 4 lights, nevertheless, which doesn’t provide the most exact perception as to how a lot cost it is carrying.
Another choice, the Zendure Supertank Pro, nearly gained this class partly as a result of it handles its cost indication with a lighted LED show that reveals precisely how a lot cost stays, expressed as a share. With 4 variable-wattage USB-C ports, a tricky exterior and included semi-hard case, it appears tailor made to behave as a power supply for cell photoshoots or nomadic workplaces. The cost speeds have been somewhat slower than the Mophie, however it did handle to provide a couple of extra share factors of cost to the iPad and the Galaxy telephone, submitting the latter 4 instances. In the top, it got here down to cost: for $50 greater than the Mophie, the Supertank Pro’s speeds and capability simply didn’t edge it out. But for those who occur to see the Supertank on sale, snap it up.
Specs: 25,000mAh, 120W max
Ports: One USB-C in/out, two USB-C out solely
Cable: USB-C to USB-C
Number of fees iPhone 14 Plus: 3.23
Charge time iPhone: 0 to 100% in 1h 45m common and 23% in 18m
Number of fees Galaxy S22 Ultra: 3.85
Charge time Galaxy: 0 to 100% in 1h 36m and 85% in 1h 12m
Number of fees iPad Air: 2.02
Charge time iPad: 0 to 100% in 2h 16m and a couple of% in 7m
Best for outdoor: Nestout Portable Charger
Plenty of battery packs are constructed to face up to drops and different abuse, however only a few are waterproof and even water resistance. It is sensible; water and electrical fees aren’t good companions. The Nestout Portable Charger battery has an IP67 ranking, which implies it may deal with being submerged in water for plenty of minutes, and Nestout claims a 30-minute dunk in a meter of water shouldn’t intervene with the battery’s operation. I couldn’t consider a possible state of affairs the place a power financial institution would spend a half hour in three ft of water, however I may see a backpacker traversing a river and submerging their pack for a couple of minutes, or a sudden downpour drenching all of their gear. So I examined by dropping the battery in a 5 gallon bucket of water for 5 minutes. After drying it off, the unit carried out as if it had by no means been moist.
The water resistance comes courtesy of screw-on caps with silicone gaskets that bodily hold the water out, so that you’ll must ensure you tighten (however don’t over tighten) the caps everytime you assume wetness is in your future. The firm additionally claims the battery lives as much as a military-standard shock/drop specification which sounds spectacular, however it’s arduous to pin down what precisely meaning. I figured it ought to at minimal survive repeated drops from chest top onto a tough floor, and it did.
As for charging speeds, it wasn’t fairly as fast as our advice for a mid-capacity financial institution. The Otterbox charged an iPhone 14 Plus to 80 % in about an hour and the Nestout bought the smaller iPhone 11 to 80 % in the identical period of time. Another factor to notice is that the provided cable is brief, simply seven inches complete, so that you’ll possible wish to use your individual wire.
Nestout additionally makes equipment for its batteries, which I discovered pleasant. A dimmable LED worklight snaps on to the highest of the battery whereas a small tripod holds them each up. The transportable photo voltaic panel jogged my memory of a child model of Biolite’s tenting panels. Nestout’s model refilled the 15,000mAh financial institution to 40 % in beneath three hours, which sounds sluggish, however is definitely pretty spectacular contemplating the compact measurement of the panels. This can be a blazingly scorching summer season, so I’d anticipate higher efficiency in additional affordable climate.
Specs: 15,000mAh, 32W max
Ports: One USB-C in/out, one USB-C in, one USB-A
Cable: USB-A to USB-C
Number of fees iPhone 11: 2.99
Charge time iPhone 11: 0 to 100% 2h common and 0 to 99% in 1h 45m
Number of fees iPad Air: 1.17
Charge time iPad: 0 to 100% 2h 23m and 0 to 17% 15m
