Emergency Hand-Crank USB Charger

The WMtec hand-crank generator is a compact manual power source for phones and other USB-charged devices. It requires no battery, solar panel or mains supply, making it useful for emergency kits, camping or any situation where electricity is unavailable. The navy-blue plastic housing measures roughly 6 by 4.5 by 3 centimetres.

Sustained Output by Hand

Power is produced only while the crank is turned, so output lasts exactly as long as the user keeps winding. There is no internal storage to bridge pauses, and the current varies with cranking speed and connected device demand. Continuous talk time or charging duration therefore depends entirely on human effort.

USB Interface Practical Limits

The single USB-A port delivers whatever voltage and current the hand-driven generator can produce at that moment. It cannot negotiate fast-charge profiles, maintain a steady five volts under load, or power devices that draw more than the mechanism generates. High-draw tablets or power-hungry phones may not charge at all.

Questions about this item

Does the hand crank generate noticeable heat or noise during extended use?

The device is a purely mechanical hand crank with no motor or fan, so it produces no electrical heat and only the quiet sound of the crank turning.

What cable or connector must I already own to charge my phone with this unit?

You need your phone's standard USB charging cable; the crank provides a USB-A output port for you to plug your own cable into.

Will this charger work with an older phone that uses a Micro-USB or proprietary port?

Yes, as long as you have the correct USB cable for that older phone, the USB-A output on the crank will deliver power to it.
