Emergency Hand-Crank USB Charger
This beige pocket generator produces USB power by hand cranking alone. It targets anyone who needs a phone charge when mains electricity is unavailable, such as during blackouts or remote outdoor trips. No batteries or solar panels are involved; muscle power is the only energy source.
Manual Operation Changes the Use Case
Because the unit has no internal cell, it cannot store energy for later — you must turn the handle while the phone is plugged in. The direct-drive design means charging stops the moment you stop cranking, so continuous effort is required for a usable top-up. There are no bundled cables or adapters beyond the bare device.
Low-Power USB Output Limits Compatibility
The tiny 6 × 4.5 × 3 cm plastic housing only delivers a trickle current suitable for basic feature phones or emergency calls on smartphones. Modern devices with large batteries will charge extremely slowly or not at all if their minimum current threshold is not met. The interface provides no voltage negotiation or fast-charge protocol.

Questions about this item
Will the plastic crank handle or internal gears need replacing after frequent emergency use?
The unit is a single plastic assembly with no user-serviceable gears or replaceable crank parts listed.
How long can I crank continuously before the USB output voltage drops under load?
No sustained-output rating or duty-cycle figure is provided for the hand-crank generator.
Does the beige casing get hot or make noticeable noise during extended cranking sessions?
The all-plastic housing has no fan or active cooling; heat and noise depend entirely on how fast you turn the crank.
