The Best USB Battery Packs for 2022

Make low batteries a thing of the past with these battery packs.

Best USB Battery Packs

We’ve all been there: You’re doing something interesting on your phone a few miles from home when that red battery warning pops up. You didn’t expect to stay out for that long, so you didn’t bring your charger. It’s the worst. Thanks to USB power packs, portable chargers require just a USB cable and no power source. They’re so much easier to move about than big, chunky chargers and charger heads and can be used anywhere.

You could be on top of Mount Everest, and they’d still work. They’d work even if you were four hours away from human contact on a camping trip. The problem now is determining which USB battery pack is the best among the bunch. Sit back and let us solve this dilemma and help you enjoy long hours doing the things you love on your phone or tablet from absolutely anywhere.

How We Picked

  • Power Capacity

    Wouldn’t it be a disaster for your battery to die while your phone battery is low? In making our selections, we picked battery power units that guarantee large battery capacity.

  • Number of Ports

    What’s better than being able to charge one device on the go? being able to charge multiple devices. We selected power banks that have multiple ports with great power-sharing capacity.

  • Size/Weight/Portability

    The majority of the utility of heavier power banks may be lost because they are difficult to transport. We selected power banks that are light enough to be moved around easily and don’t bulge out of your pocket.

  • Cost-Effectiveness

    USB battery packs don’t cost much. However, you can invest a little more in a good one with all the bells and whistles. Those with higher capacities also tend to cost a little more.

Who This Is For

The products advertised on this list are for people who spend loads of time outside the house. They can be used by anyone, but more so by people who don’t enjoy the burden of taking their chargers everywhere, searching for working power points, and standing or sitting by until their phones are charged.

What is a USB battery pack?
USB power packs are often small, portable devices used to recharge battery-powered items like phones, watches, tablets, and lamps on the go using a USB cable. They range in capacity and size depending on need; however, the average USB power pack is around the same size as a smaller iPhone and can fit right in your pocket.

Is a USB battery pack worth buying?
If you are a cellphone user who is out often for work, school, or just fun and leisure, yes. With it, you can charge your phone anywhere at any time. No, we’re not exaggerating. There’d be no need to tolerate turtle-speed car charging any longer. On some days, you just can’t put your phone down to charge. With USB power packs, you can charge from wherever you use it — from a table, a rollercoaster, the top of a bunk bed, in the toilet, on a bike, or on a hike. Anywhere.

Importance of amps and power output
On a battery pack, the number of amps tells you how fast it charges. The higher the amps, the faster your device charges, and vice versa. The power output also determines the charging speed. Different devices have different power ratings. This, combined with the power output of the USB power pack, also determines how fast (or slow) charging will be.

Why You Should Trust Us

We know the pain of seeing that 5% warning when you still have so much to do on your phone. We, and millions of people across the world, have used simple USB battery packs to solve this issue, and we want the same for you. Your phone should never be dead, and we want to help you make sure of that.

How We Picked

USB battery packs are most likely new to you, so we expect that you may be a little confused about what to look out for or where to look. In line with our continued efforts to make your life much easier, we’ve done all the boring research on your behalf. We’ve sorted out the trash from the goods and come up with a system to find the best USB battery packs for you.

First things first, we ensured that all our picks had respectable power capacities. More power capacity means more charging time for you. Some battery packs can charge phones to 100% more than once, and, naturally, we were more inclined toward these battery packs not on this list.

It’s just annoying to have things awkwardly bulge out of your pocket. We share this sentiment and put our efforts into finding battery packs that didn’t compromise on quality and capacity while being small, light, and easy to move around.

We studied reviews and user experiences to ensure that nothing was missing from our selection process. We found helpful tips concerning the outside strength and durability of certain products and discarded them in favor of better, more reliable picks. In all of this, we still ensured that our picks were fairly priced and unlikely to cause you to regret or any level of buyer’s guilt.

Who It's For

This Anker PowerCore battery pack is the ultimate fix for all on-the-go battery problems. With it, there’s no need to carry chargers around or worry about cutting trips and fun times short because of a low battery warning.

Why It's Great

With this battery pack, you can fully charge your mobile phone and other devices multiple times. Some users say they charge as much as eight times with this battery pack. Apart from its outrageous battery capacity, the charging speed of this battery pack is almost second to none. You can go from zero to full charge in no time at all. This option also comes with two USB ports, so you can charge your phone and another device like your Apple Watch or Nintendo Switch at the same time.

Potential Flaws

Given that this battery pack was released before the growing popularity of USB-C ports and cables, you would have to charge it with standard USB cords. So far, that’s the only thing close to a flaw in this choice.

Other Features

When pitted against competitors, this choice comes out on top in almost every metric. It’s by far the most sold battery pack in the USA and for good reason too. It comes with an 18-month warranty that is evident in its strong casing and sturdy build.

Who It's For

There’s no better battery pack for people who want charged devices and the added incentive of contributing towards more environmental consciousness. It’s great for all kinds of mobile devices, not just ones owned by carbon-conscious or energy-saving people.

Why It's Great

It fits well in your palm, as it’s about the size of a debit card. It also comes in bright, pretty colors like turquoise and dark green that are not commonly associated with devices of its kind. It packs all of this and more together without compromising on charging speed or battery capacity.

Potential Flaws

Some users claim that its 10,000 mAh capacity is far less than they require. However, we believe it's right as long as it's used for what it was designed to be: a backup charger to keep your mind at ease in unexpected situations and to charge your devices while on the go.

Other Features

No other battery pack in this price range or level can match the Nimble Champ for aesthetics. It’s no slouch in terms of performance, either. It can charge most phones to 100% two times in a reasonable amount of time. It is super lightweight and fits right wherever you want it — in a pocket, bag, or purse.

Who It's For

If you struggle to afford or comprehend spending over the top on charging reinforcements while still being wary of unplanned battery failures and interrupting device usage, look no further than this battery pack.

Why It's Great

Anker is a brand well known for serving only products of the highest quality. Our top pick is from their stead, and if you can’t find the means to get our top pick, you can still enjoy the fast charging speeds, strong build, and portable design that Anker battery packs are known for.

Potential Flaws

This mini battery pack, though quite small, has an uncommon cylindrical build that may not be the best fit for your pocket. It fits nicely just about anywhere else.

Other Features

Trying to find a better value battery pack than this is almost destined to be futile. Its charging speed and strong build are bound to make you marvel. There’s the bonus of it being from the most reliable battery pack manufacturers out there, so you know you are not getting a product that gives up or stops responding after a few weeks or months of usage.

This battery pack would be the perfect choice in a world where our best picks didn’t exist.

This option is still a strong contender because it combines a powerful battery with quick charging. Given that it has both USB-C and USB-A ports, it works great with a variety of gadgets. It has an incredible 45 watts of fast-charging power, which is more than enough for flagship devices.

Who It's For

This choice is for people who, unfortunately, couldn’t get their hands on our more favored picks in time, as they run out pretty quickly.

Why It’s Great

It’s a highly rated alternative and is only ranked this low due to the strength of the competition. It stands out for its ability to charge a vast range of devices, including laptops, so if you plan to charge your laptop with a battery pack, look no further.

Potential Flaws

It does not offer the most convenient hold, and slipping it in your pocket may not be too comfortable either. Also, it’s priced similarly to our best picks while offering just a little less in terms of speed and reliability.

Care and Maintenance

To ensure good use of your battery pack, keep them in a safe, dry place, like in drawers or on the work table. Ensure that cords are not tangled, unnecessarily stretched, or flung around. To remove dust from ports, attach a tiny straw or cotton bud stem to a can of compressed air. Spray compressed air into the port a few times from multiple angles and watch the dust clear out. Use a cotton bud to clean out larger ports and stubborn, more visible stains that gather around the ports. When charging or using, watch the temperature to ensure that you’re not overloading and putting yourself in danger of an explosion or burned port as a result of an overheating battery pack.
