All-metal mechanical alloy sawtooth knob gear hand-cranked generator mobile phone holder
Core highlights
Hand-cranked generator, outdoor emergency tool
No need to rely on sockets or batteries🔋 Turn the handle to generate electricity and recharge mobile phones and small devices! When camping outdoors or in case of power outages, shake it to easily recharge and get rid of "battery anxiety", which is super reliable at critical moments.
Mechanical structure, play with a sense of technology
Metal gears and linkage parts are clearly visible⚙️ When turning the handle, the gears run in an orderly manner. It is not only a charging tool, but also a "mechanical aesthetic ornament" on the desktop. Shake it when you have nothing to do and feel the charm of mechanical transmission. Technology fans and mechanical control are ecstatic.
Small and portable, "shake" at any time
The size is only 10cm×7cm×11.5cm, with a net weight of 600g, which can be easily stuffed into a backpack🎒, does not take up space, is easy to carry, and "hand-cranked generator" is always on standby.
