Affordable cheap well builded – Dynamo Hand-Crank USB Cell Phone Emergency Charger Reviews

Involvement:General (knows how to use it) - Ownership:1 day to 1 week

Light, robust, include a red led to show it's generating electric current, portable, compatible (It has a usb standard connection)
It worth only for features that needs low current. I was able to charge my old LG phone, but not my BlackBerry, not my tablet
It a good last resource, when the electricity was gone, when the sun was gone, when there is no usb at the sight
Its affordable, cheap, robust, durable charger, with no needings (no electricity, no sun, etc). Its limitation is the amount of current that generates
