Not ordinary product... – Dynamo Hand-Crank USB Cell Phone Emergency Charger Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Light, compact. Inner parts is well oiled with consistent grease.
One of two dynamo has defects right out of the box. Middle wall inside of dynamo is broken, Superglue do the job. Plastic seems weak, but it's do their job.
In my opinion, not suitable to powering smartphones and other "hungry" devices. Tested on Huawei smartphone, when charging begins - strong braking force of electricity generation appears, hard to rotate. Mechanism begins to tell you "AggrrRRrrrRRrr.." :)
Good for simply phones. Useful in places far of civilization :) One man operates, other man doing the call.
