Will smartphone batteries last as long as we need them? Maybe not. That's why we rely on external batteries to stay connected for hours or even longer than usual. But in 2018 you do not want to use any external battery. Modern Android phones have a quick charge – so should your portable charger.
While we're sure that our list below contains some great external batteries for your smartphone, it's not the nuts and bolts. There's a lot of Auxiliary Power Options for Android users. If you encounter a portable charger, whether online or in the store, you should look for some specifications that I will describe below.
Each battery, whether external or internal, is described by its capacity. This is simply a measure of how much charge the battery can hold. The larger the number (expressed in mAh), the greater the charge and the longer the battery can charge your device.
The batteries in our Roundup run from 8,000 to 26,800 mAh.
It's not enough for your external battery to be USB Type-C compliant. Make sure the battery also indicates "PD" (or Power Delivery) on the label. USB-C PD batteries can charge any compatible smartphone quickly. On the other hand, if the battery only specifies Qualcomm Quick Charge Compatibility, this may not include all fast charging devices.
While USB-C PD External Batteries may not be as common as generic portable chargers, there are still plenty of great options to choose from. While some on this list may be a little expensive, you can grab an external battery for as low as $ 29.99. Take a look at our overview below and see which portable charger works best for you:
