PowerEver

Lambda Nu PowerEver is a tiny PCB that turns any commercial USB power bank into a non-stop power supply while minimizing self-drained current. It is user-adjustable and is compatible with nearly all power banks in the market. The PowerEver enables the power bank to never run short of mobile power for most portable USB-powered devices. The Lambda Nu PowerEver is designed to consume as little current as possible while passing most of it to the connected device. This current is freely adjustable using a single push button on the backside of the PCB to increase or decrease the draw to suit the power bank's design.
