portable wooden box recharges disposable alkaline batteries even with power bank
"RegenBox 1 is a portable wooden box designed to recharge disposable AA and AAA alkaline batteries, even with a power bank. A DIY kit that users need to assemble themselves, the device comes with a USB port and power cable that supply energy to the recharger box. The user receives separate parts rather than a finished product, from the printed circuit board to electronic components. However, they need to be handy people because these parts must be soldered together,"
"Power is supplied through a USB cable, allowing the device to run from common power sources such as power banks, computers, or adapters. No dedicated charger is required, and the electronics are enclosed in a case made from wood that is cut and engraved by machine. The case protects the circuit while allowing access when repairs or changes are needed since it is not sealed or locked."

The product is sold as a DIY kit whose parts include a printed circuit board, electronic components, a USB port, and a power cable that can run from power banks, computers, or adapters. Users must solder components and use tools such as a voltmeter, pliers, wire cutters, and a screwdriver to assemble and verify battery voltages before regeneration. The wood case is machine-cut and engraved, not sealed, and allows access for repairs. The system supports only AA and AAA alkaline cells; modifying for other formats is the user's responsibility. A digital manual link is included.
