This battery holder accepts 3x AA batteries and features a USB (female) output giving you a different way to power your project compared to traditional battery holders. The onboard switch allows convenient power control and the slide-out top cover makes it quick and easy to change batteries.

In terms of voltage, AA batteries are usually available in 1.2V (rechargeable/carbon-zinc) or 1.5V (alkaline), meaning this USB battery holder can offer between 3.6V and 4.5V depending on which battery chemistry is used and their condition.

Whilst this won’t power most 5V development boards, it works great with the Raspberry Pi Pico (when combined with a Micro-USB cable) which can accept 1.8V to 5.5V input- so you really can’t go wrong no matter which type of battery you use!

We also think this might be super-duper for powering simple circuits and projects (or even other 3.3V devices with a wide input range). Perhaps combine with a USB breakout cable or simply splice one of your old unwanted cables at home?

We also stock a more compact AAA version (same voltage, less capacity) and a 4x AA version which is good for 4.8V to 6V.
