I ordered three solar chargers, one for myself and 2 for gifts. The arrived today and I was so excited to receive them. I'm a senior and not very tech savvy, but I can read and follow instructions. When I saw the manual for these chargers I could have cried. I've never seen anything so terrible, in no way understandable. This sure doesn't speak well for the product. It would take pennies to have these properly written so the cultures buying product could follow the instructions, so the manufacturer can't be a very good reliable company. I'm going to post photos so you can understand what I'm dealing with. I've not been able to reach the seller yet.
