FRENDO Power Sun 3.5 Solar Charger

The device did not work at all when I held it in my hands. Got a really quick and good response from the product manager at Frendo who recommended to send it back because it was obviously defective. I decided to take the refund and buy a GoalZero device from my local hardware store instead because I needed something urgently.What I did like about the Frendo is that it's really lightweight and comes with all the necessary adapters. However, the output socket is mounted a little peculiar and the whole thing doesn't really look like "heavy duty" outdoor stuff. Yeah right, it's a solar panel, not a shovel, but anyway ... Also, the battery cannot be removed from the cells. But, the GoalZero Guide10 which I own now, cost me almost twice the price and weighs a lot more. In terms of price and weight, I haven't seen anything like the Frendo Power Sun 3.5 in this power class so far.
