There are plenty of dynamo based hand chargers for your electronic gadgets. What makes the VoltMaker better or different? First of all, they have the best infomercial video I have seen in a while. If nothing else it is worth a laugh, watch it below. Secondly they create power by twirling or spinning the dynamo around. This 6-inch, 10-ounce dynamo charger has a 2,000 mAh battery and can also be wall charged "if you are lazy". You get all that goodness for $69, strap on the flashlight attachment and the new total is $89. Yes I am on the list for three, hoping they hit their $200,000 indiegogo goal.
