1.Anker PowerCore 10000, One of the Smallest and Lightest 10000mAh External Batteries, Ultra-Compact, High-speed Charging Technology Power Bank
Why It’s A Top Pick: The Anker PowerCore 10000 is especially small and light for the amount of power it packs. With enough juice to charge an iPhone 6s just under 4 times, you’ll have plenty of power to get you through the day and a charger that fits easily in your pocket.
Downsides: While it’s a great power source, it doesn’t support pass-through charging. Still, for the size, it’s an incredibly useful power pack.
2.Portable Chargers 16750 RAVPower 16750mAh External Battery Pack 4.5A Dual USB Output External Phone Charger Power Pack Power Bank (iSmart 2.0 Tech) for Nintendo Switch, iPhone 8, Galaxy S8 (Black)
Why It’s A Top Pick: Despite being about the same size as your phone, this 16750 mAh pack can charge an iPhone about 6 times on a full tank. It’s fully featured, too, with two charging ports, pass-through charging, a built-in flashlight, and blisteringly fast charging speed.
Downsides: This RavPower unit is slightly awkward to carry around. It’s about twice as thick as a typical phone and a smidge wider, meaning you won’t really want to stick it in your pant pocket. It’s still great to stick in a jacket pocket, purse, or even your car.
3.Anker PowerCore+ mini, 3350mAh Lipstick-Sized Portable Charger (3rd Generation, Premium Aluminum Power Bank), One of the Most Compact External Batteries
Why It’s A Top Pick: Only the size of a lipstick tube, this power bank contains about one extra charge for most phones. If you want a bit more power that you can carry around all day, it’s one of the best solutions.
Downsides: While this Anker mini is crazy small, it doesn’t have the biggest tank, nor does it charge particularly fast. The RavPower above can hold about 6 times as much charge and can charge your phone up to 2.4 times as fast.
4.Anker 20000mAh Portable Charger PowerCore 20100 – Ultra High Capacity Power Bank with 4.8A Output, PowerIQ Technology for iPhone, iPad & Samsung Galaxy & More – Black
Why It’s A Top Pick: The Anker PowerCore 20100 can hold enough power to charge your phone a full 7 times. This means you can last a full week at one charge/day. It’s got two ports, both of which deliver an impressive 2.4 amps for quick charging.
Downsides: Like the RAVPower 16750 above, this power bank is slightly awkward in size. It’s longer and narrower than a typical phone while being a bit thicker. This makes it pretty hard to put in a pant pocket. It’s fine for jacket pockets or purses, however.
5.[Upgraded] Poweradd Slim 2 Most Compact 5000mAh External Battery 2.1A Ouput Portable Charger with Smart Charge for iPhones, iPad, Samsung Galaxy, HTC and More – Blue
Why It’s A Top Pick: This crazy compact power bank offers a full 2.1 amps of charging speed, letting you fully charge a phone in a mere two hours. A respectable 5000 mAh lets you fully charge most phones while leaving a little bit of juice in the tank.
Downsides: While this ultra-compact charger has great capacity for its size, you can get power banks that store more than twice as much power. They’re not as easy to transport, however.
6.MANMAI 20000mAh Power Bank (Dual USB Port, 3.1A Total) External Portable Charger Battery Pack Portable Charger with LED Flashlight for iPhone 7, iPhone 8,iPad Pro, Galaxy S8 Note8 and More
Why It’s A Top Pick: This power bank comes with plenty of capacity while being incredibly light. If you don’t want to add any unnecessary weight to your purse or pocket but you still want plenty of charging power, this MANMAI is a perfect choice.
Downsides: While it’s surprisingly light for its capacity, this MANMAI is slightly lacking in other features. It only offers 2.1 amps of output vs the 2.4 of other chargers. It’s also only got one input, meaning it’ll take a while to fully charge.
7.Yoobao Q12 12000mAh Rapid Charge Power Bank Ultra Thin Portable Charger with Qualcomm Quick Charge 3.0 and HUAWEI FCP Dual USB Output External Battery for Samsung Huawei iPhone LG HTC and More-Black
Why It’s A Top Pick: This small 12,000 mAh bank takes full advantage of the latest charging technology to charge your devices faster. While other power banks only operate on one voltage, this device can switch to a higher voltage to dramatically cut your charging times. It’s compatible with Qualcomm Quick Charge 3.0 and HUAWEI FCP.
Downsides: 12,000 mAh is a decent amount, but this power bank is about the same size as many of our other picks with almost twice the capacity. This means you won’t get as many phone or tablet charges out of this brick as you might expect. It’s also a bit too long and thick to fit into a pants pocket easily.
8.Elefull Thin Portable Power Bank 10000mAh Torch 2USB Ports Quick Charge Mobile Phone Camera Speaker 5V device Charge iPhone samsung HTC LG Huawei etc. (Gold)
Why It’s A Top Pick: This basic 10,000 mAh bank has a sturdy metal case that’ll protect it from the rigors of everyday carry. It’s conveniently shaped and sized to fit neatly in a pant pocket while still offering plenty of charging power.
Downsides: With a peak output of 2 amps, this bank won’t keep up with 2.4 amp chargers. It’s also got less than half the capacity of some competing units. While it’s great to carry in your pocket, it’s not going to compete with something you can stick in your purse.
Why it’s a top pick: Fantastically affordable, this Aibocn power bank is a great option to keep your devices charged on a budget. It’s got most of the features you want, too, like a 2 amp charging port and an easy-to-carry form factor.
Downsides: Only one of this Aibocn’s two USB ports supports a full 2 amps, and that’s still a fair bit lower than the 2.4 amps offered by many competing models. Additionally, it might be a bit long for women’s pants pockets.
There are three major considerations you should take into account when choosing a power bank: capacity, size, and charging speed.
Capacity is measured in mAh, or milli-amp hours. Think of this unit like “gallons” on a gas tank. The more mAh a power bank offers, the more times it’ll charge your phone. 3000 mAh is enough to charge most phones about once.
It’s worth noting that high capacity power banks take a long time to charge. This is a pretty universal thing. Since you’re usually getting several phone charges out of a single power bank charge, however, it’s not a big deal to leave your power bank plugged in overnight.
Power banks come in a variety of sizes and form factors. The bigger the power bank, the higher capacity it can offer since manufacturers can put in more battery cells and don’t have to worry about heat as much. How you’ll use your power bank will determine how big it can be. If it NEEDS to fit in your front pocket comfortably all day, you’ll want a light unit that’s small in every dimension. If it can go in a purse, backpack, or another bag, however, you’re much less worried about it being a bit bigger or having an awkward length.
Finally, power banks don’t all charge at the same speed. Small banks tend to only charge at 1 amp, while larger banks offer up to 2.4 amps of charging output. This means that they’ll charge your phone up to 2.4 times as fast. Be wary of power banks advertising more output — it’s often a sum of the output of multiple USB ports.
Once you’ve determined the capacity, size, and charging speed you need, you’ll be able to make an educated decision and pick the power bank that’s best for you!
