10 Best Slim Portable Battery Chargers



In this buying guide we’ll share a list of the best slim portable battery chargers for your phone, tablet, MacBook, and more. A little accessory you can carry everywhere and recharge your phone on the go.

And while we’ve recommended countless excellent portable battery packs in the past, not everyone wants to carry a bulky brick in their pocket or backpack. Which is why we found some of the absolute slimmest portable battery chargers around.

Our list has chargers for under $12 that are slim enough to fit in your wallet or slightly thicker battery packs with enough juice to recharge the latest Galaxy or iPhone, or even keep your Nintendo Switch going with USB-C power delivery.

A portable battery charger is exactly what the name suggests. A battery pack similar to what’s inside your phone, only with multiple USB ports so you can charge your phone and other devices on the go without sitting next to a wall outlet.

These battery packs come in several different speeds, sizes, and shapes, so knowing which one to buy is important. Certain models are thin but slow, while others offer fast charging technology and enough output power to charge a Macbook.

A lot of accessory brands make portable battery chargers, but sometimes you just want to carry something slim and lightweight. If so, Anker, Moshi, Tronsmart, and Belkin are some of our favorites. Plus, there are countless other excellent options worth buying in our slideshow below.

Anker is America's leading USB charging brand, and they offer portable battery packs in all different shapes and sizes. 

The new Anker PowerCore II Slim is one of the best options on the market. You're getting 10,000 mAh (enough to recharge your Galaxy S9 or iPhone X three times) in an extremely slim package all for around $35. That way you're never left without a phone or stressing that you'll run out of battery. 

This portable battery pack is roughly the size of a phone, so it's already something you're used to carrying around. Plus, it'll slide into a shirt pocket, purse, or backpack with ease. 

It'll universally charge your iPhone, Android, or Samsung Galaxy at the fastest speed possible thanks to PowerIQ and 18w Quick Charge technology inside. You get a full-size USB port, a small USB-C port, and 4 LED lights so you know how much juice is left.
