Benex USB Wind Up Eco Charger

There are plenty of hand-powered and solar powered chargers out there, so what’s new about this one? The USB Wind Up Eco Charger doesn’t have an internal battery like other chargers. Instead, it has a USB socket that can be used to directly charge any gadgets that are charged via a USB cable.
Although this means that gadgets are only charged whilst you are cranking away, it does mean that the Benex Eco Charger produces up to 5 times more energy compared to the hand-crank-charger-with-battery variation. Since all batteries degrade eventually, since this eco charger doesn’t haven an internal battery, it’ll last a really long time too!
