The best battery packs

  • The best battery packs help us get through the busiest of days, providing portable power for our smartphones, tablets, and even laptops.
  • With a large capacity, fast charging capability, and a reasonable price, the Elecjet PowerPie is our pick for the best battery pack you can buy in 2020.

As wonderful and multi-functional as our smartphones are, they often run out of power at inconvenient moments. The last thing you want when you’re trying to call a car at the end of the night is a dead phone. The best battery packs are the perfect back up. They come in all shapes and sizes, with different features and capabilities, and many of them can charge up tablets and even laptops now, as well as phones. 

Stick a battery pack in your bag or pocket, and you can rest assured a dead battery won’t leave you high and dry. But, how do you pick the right battery pack for you? There’s a bewildering array of options on the market. I’ve tested more than 100 of the best battery packs — and the worst — over the last few years, so I can recommend the right pick for different scenarios. 

The best battery pack for you depends on the device you want to charge, how much you want to spend, and what kind of capacity you need. We’re about to outline the cream of the crop, but we’ve also listed what else we considered and would still recommend. Before we dig into the list, let’s look at some important considerations to help you choose.

How to choose a battery pack 

The last few years has seen some major advances in battery pack technology. Capacities have grown, charging speeds have increased, and battery packs are more portable than ever. But, there are still a few questions to ask before you shop for a new battery pack.

What device or devices do you want to charge?

You can get battery packs now that will happily charge a smartphone, tablet, or even a laptop, but you need to check compatibility before you buy.

What kind of charging cable do you need?

Some battery packs have USB-C ports, some have USB-A, and some have built-in cables. They don’t always come with cables in the box. If you want to charge an iPhone, you may need a USB-C to Lightning cable or a USB-A to Lightning cable. Most Android phones, and many tablets and laptops now, will require a USB-C cable. Think about what type of cable you need, and make sure any cable you buy is capable of the charging speed you’re looking for.

What is the top speed your device can charge at?

Manufacturers are constantly figuring out ways to increase the top charging speed for phones and other devices. At the time of writing, the top wired charging rate for iPhones, for example, is 18W. Some manufacturers, such as OnePlus or Huawei, offer much faster charging rates, but require the use of proprietary charging technology. Many battery packs are capable of fast charging now, but check to make sure they are capable of fast charging your particular device before you buy.

What capacity do you need?

Battery packs are more portable than ever, but they will generally be larger as the charging capacity inside increases. It’s also important to note that you will never get the full stated capacity when you use a battery pack. Most manufacturers offer an estimate on how many times a battery pack will charge up a specific device, like an iPhone. 

How long does the battery pack take to charge up?

It’s not unusual for battery packs, even battery packs that are capable of fast charging other devices, to take a long time to charge up themselves. The best battery packs will recharge quickly, but you will likely need to use a fast charger and the right cable to get the top speeds.
