It would be cool to just plug a USB cable into a battery, wouldn’t it? Well, USB-C ports and battery charge circuitry are small enough, and battery chemistry is good enough to allow that.
I’ve been testing many USB rechargeable batteries, and the brand that’s consistently been a winner for me is Paleblue.
Also: Should you buy rechargeable batteries in 2025? These USB-C ones say yes.
The company offers a wide range of rechargeable lithium-ion batteries, AAA, AA, C, D, and 9V, as well as assorted bundles. These are superior to the older nickel-metal hydride (NiMH) rechargeable batteries, which need their own chargers.
Each kit has batteries, a 4-way charge cable, and a plastic box to hold the batteries.
