Because science. You are converting DC to AC then back to DC. Lots of loss doing that. They make small USB adapters specifically for this. Buy one of those. |

It also has a light and will jump a car. THIS. Easiest solution especially since solar takes forever to charge better to charge an electronics battery pack like a mophie juice pack and go from there. Make sure if you have higher amp devices like an IPAD or tablet it's rated for 10 amps not 5. The battery pack that is Last Edited by _____tard on 08/19/2012 11:23 AM |

What you have is really a toy solar panel. Solar cost big money, check out solar websites for good info like solarpaneldotcom |

A 20 watt solar panel is not much of a panel. Usually you need a solar charge controller to properly charge a lead acid battery. Your panel should put out 16-22 volts and a charge controller would convert this to 14.4 volts for bulk charge and 13.3 volts for "float" charge. If you could buy a 90 or 100 watt panel it would work a lot better, look at sunelec.com... |
