Generate emergency power by hand when utility power is unavailable, with USB and adjustable voltage outputs for compatible portable electronics.

• Manual generation: The blue, metal F20 delivers up to about 20W; crank clockwise, as output depends on cranking speed.
• Output options: No-load settings are 3V/6.6A, 5V/4A, 6V/3.3A, 9V/2.2A, 12V/1.6A, and 15V/1.3A; direct output reaches about 28V. Actual current varies with the battery being charged.
• Use with care: Set the regulator to 5V before using USB. The generator stores no electricity; avoid high-speed cranking with devices under 3W and read the included safety instructions.
• Compact kit: The rectangular generator measures 12.7 × 8.6 × 8.8 cm and requires assembly. You receive the generator, handle, and English manual.
