Pretty decent solar panel but as it seems with all solar panels in similar price range it's nominal power is probably only possible if you take a rocket and measure it in the vicinity of the sun, just before it starts to melt. The rocket I think :P I joked a bit, but honestly - the specs looks like to be very optimistic. Haven't measured the effective power but it was not able to charge a simple 4000 mAh (with 5 Volts it means 20W, right(?)) battery pack when connected for multiple sunny days, positioning the panel correctly, disconnecting it before sunset, connecting it at sunrise. Will test it further to get better data, looks like I have to make a simple logging tool to be able to track charging possibilities... At the same time I need to check this in the summer, with much stronger sun... Nice pack with accessories. Am pretty sure that this can not charge a car battery without the rocket ( :D ), but I will be using the accessories for other purposes :D But - for this price I think it is worth the money - I will try to charge a smaller battery as it should probably work better.
