6 x AA battery holder with 2.1mm plug – Make a portable power brick with plenty of juice! Use Alkaline AA’s for a 9V 3000-4000mAh power supply, or rechargeable NiMH for 2000mAh 7.5V supply. Either one is good for running electronics that have a 5V voltage regulator (thus requiring a 7V+ supply). Will last about 10 times longer than a 9V. Perfect for portable Arduinos! Batteries not included. Some quick soldering is required to attach the jack to the holder.

  1. I can’t quite tell from the photos – does it have a built-in switch?

  2. @j – no switch
