Power Banks

Don’t Leave Home Without One

The best portable chargers help keep your phone alive when you need it most. They also power our phones, tablets, Nintendo Switch consoles and even our laptops when the need arises. Since we all find ourselves out of the house with low battery life at some point, you’ll need a portable charger.

Not long ago, we completed a litany of tests on 10 of the best portable chargers, pulling from the big brands and popular competitors. We tested how fast they charge and how many full phone charges each power bank stores. Though these portable chargers all regularly appear on bestseller lists, they are different in a number of important ways.

We’ve got these best portable chargers ranked in order of what we ourselves would buy, with shoutouts for the best portable charger, as well our favorite compact charger and the best portable charger for USB-C.

How to choose the best portable charger for you


Finding the right charger capacity: You’ll often see a four to five-digit number, with the letters mAh following it, and that’s your first big indicator of how much this charger is right for you. If you’re constantly refueling your phone and other gadgets, go for at least 10,000mAh. For each extra device you charge, add at least 5,000 to the mAh rating you’re looking for. Just need to prevent your device from hitting 0 on late nights out? You’ll be good with something in the under 5,000 mAh rating, provided you remember to charge it often.

Be a ports authority: If you hold onto your devices forever, and don’t already know what a USB-C port is, you can probably just get whatever fits your price. But if you’re the kind who wants faster charging, look for a brick that has PD in its name. The best portable chargers, at least for my money, charge devices the fastest and use the Power Delivery (PD) standard. Also, their USB-C ports mean you can refuel these power banks with the same cords used to charge modern laptops.
