K-TOR POWER BOX Instruction Manual page 7

Spin
Crank in a forward bicycle motion, accelerating quickly to 90 RPM (1.5
rotations per second) for full power and efficient operation.
Compatibility
The K-TOR Power Box 50 pedal power generator provides 14 Volt DC
power and has been designed to charge directly 12-Volt sealed lead acid
batteries. Devices that plug into an automotive 12-Volt socket and are
within the maximum power range such as USB outlets can be used.
Ensure devices plugged in are connected securely. Do not use devices
that are loose as a poor connection can create arcing and a fire hazard.
