CHARGING SPEED, CLEARLY EXPLAINED

30W USB-C. 18W USB-A. 5W wireless.

USB-C PD input / output	Up to 30W: 5V/3A, 9V/3A, 15V/2A or 20V/1.5A
USB-A output	Up to 18W: 5V/3A, 9V/2A or 12V/1.5A; compatible fast-charging devices required
Wireless output	Up to 5W for compatible wireless-charging devices
Ports	1 USB-C input/output port + 1 USB-A output port
Shared output	15W total when multiple outputs are used; power is shared, not added together

Use USB-C PD for the fastest supported wired charging. Place a compatible wireless-charging device over the circular charging area for cable-free top-ups.

Maximum power depends on the connected device, supported charging protocol, battery level and cable. Wireless charging is not a magnetic attachment feature. No pass-through charging function is claimed.

HAND-CRANK EMERGENCY BACKUP

An extra way to generate power.

When an outlet is unavailable, unfold the crank and turn the handle to generate emergency backup power.

5W generation (5V/1A)
At approximately 180 handle revolutions per minute — about three turns per second.

Generation depends on turning speed. Hand cranking is for emergency top-ups; the 5W generator specification is separate from the 30W USB-C charging specification. Charge by cable before leaving for a full starting reserve.

SOLAR, LIGHTING & OUTDOOR USE

Useful backup features, day and night.

2W peak solar panel: position the solar-panel face in direct sunlight for gradual replenishment.

Dual LEDs: 100lm combined high mode, 30lm low mode and SOS flashing. High-mode runtime is at least 20 hours on the 20,000mAh model or 50 hours on the 50,000mAh model, from a full charge at 25°C with no other loads.

PC + ABS housing with protective corners: IPX4 splash resistance with port covers closed, plus a built-in compass and battery-level indication.

Solar output varies with sunlight, panel angle and temperature; it is supplemental charging, not a promise of a full charge in one day. Do not immerse the unit or charge through wet ports. Keep the compass away from magnetic interference.
