The Story
This compact battery holder acceptsĀ 3xĀ AAA batteriesĀ and features a USB (female) output giving you a different way to power your project compared to traditionalĀ 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, AAA batteries are usually available in 1.2V (rechargeable/carbon-zinc) or 1.5V (alkaline), meaning this USB battery holderĀ can offer between 3.6V and 4.5VĀ depending on which battery chemistry is used and their condition.
Whilst this won't power most 5V development boards, it works great with theĀ Raspberry Pi PicoĀ (when combined with aĀ Micro-USB cable) whichĀ can accept 1.8V to 5.5V inputĀ - 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 aĀ USB breakout cableĀ or 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 -Ā 4.8V to 6V.
