This compact battery holder accepts3xAAA batteriesand features a USB (female) output giving you a different way to power your project compared to traditionalbattery 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, AAA batteries are usually available in 1.2V (rechargeable/carbon-zinc) or 1.5V (alkaline), meaning this USB battery holdercan offer between 3.6V and 4.5Vdepending on which battery chemistry is used and their condition.

Whilst this won’t power most 5V development boards, it works great with theRaspberry Pi Pico(when combined with aMicro-USB cable) whichcan 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 aUSB breakout cableor simply splice one of your old unwanted cables at home?

We also offer a larger 3xAA version (same voltage, more capacity) and a 4x AA version which is good for higher voltages – 4.8V to 6V.
