Title: better alternative $19.90 for most applications
Review: For $19.90 (link attached)Kensington 33060 75 Watt Portable Power Inverteryou can buy a small 75 watt inverter, and plug it into your car cig lighter outlet to power or charge laptops etc. I know you lose some portability, although they make cig lighter extention cords up to 20 feet long. I can see that it would be nice to have it in your tent and haul it around or whatever, but given that the best recharge rate in the sun is less than 1/2 a watt per hour and the unreplaceable battery will surely die in 4 years under the best of conditions, before you know it this will make a great boat anchor. The solar aspect seems cool, but if its basically useless and you throw it away in a few years ( more batteries and silicon in a landfill) that is not so cool.
Is the review positive or negative?
