PowerEver – A tiny device that turns your generic power bank into a non-stop power supply

PowerEver is a tiny electronic board that will keep your commercial power bank running non-stop while minimizing self-drained current. It is user adjustable and is compatible with nearly all power banks in the market. This means that your power bank will never run short of mobile power for your electronic gadget.

This board is perfect for electronic enthusiasts, field engineers, and students as well as anyone needing a mobile power supply using commonly available power banks. Help save the environment by maximizing power bank usage, especially for older models that cannot provide enough power to mobile phones but are still usable with less current-hungry electronic devices. For example an Arduino, ESP8266 and more.

Features

• Use generic mobile phone power banks as a regular DC 5V power supply for powering all kind of gadgets and electronic boards
• User adjustable through button triggering to suit almost all power banks
