The 7 Best USB Rechargeable Batteries
Editor's Notes
December 18, 2020:
Selections like Paleblue Smart Batteries and the Sorbo 4-Pack represent a more recently invented style of USB rechargeable battery, one which utilizes lithium-ion cells and charges directly from a USB power source without an intermediate charging bay. While this offers distinct advantages in terms of portability and ease of use, the technology has not yet become completely reliable and shouldn't be counted on for delicate or expensive devices. For this reason options that feature a more traditional nickel-metal hydride chemistry, such as the EBL Charger and Batteries Set and the EBL Rechargeable 8 Pack, are still worth considering. These choices are bulkier and slightly more complicated, but they are still a convenient option for many of the same situations, as they too can be charged via USB from sources like power banks and car chargers.

Choosing the best USB rechargeable batteries came down to balancing capacity, charging time, and durability. High capacity batteries are great, but if you have to wait an excessive amount of time for them to juice up, they will rarely be ready when you need them, especially if you put them into a device you use every day. We also did our best to include models in a range of sizes to suit every need.
