I bought one of these a coujple of years ago and have always felt its recharge speed when using the solar panel was so slow as to make me question if it worked. I am going away and so checked on what people thought. Here are my notes and links. …<\/p>\n\n\n\n\n\n\n\n
The charging speed is very slow, this video<\/a> measures a full charging period in days. The comments on the amazon sales page<\/a> suggest that it’s better than nothing if one has no availability from the grid so for short outdoor camping\/hiking holidays it could be good, particularly as a fully charged bank will charge up my phone several times, although if you have more than one device, it may not be good enough. Having written this, I took it away on a trip and put it on the window sill, it was over 3\/4 full and took three days to fully charge, in line with the video linked to above. <\/p>\n\n\n\n Here’s a negative review, Should I buy a solar power bank?<\/a> but I also found the more evenly expressed article, “why, what and how<\/a> which introduces the concept of having the device in two parts, a power bank and a solar charger. I also think these people have something to sell. <\/p>\n\n\n\n For me the big lesson for today is that solar charging is very slow. I assume it’ll get better, but I am not sure it has yet but my bank is couple of years old. This is not yet going to save the planet.<\/p>\n\n\n\n It caused great interest at Tallinn airport, where I was told, it is only just permitted on aircraft as hand luggage. Probably designed to be so, but glad I was able to keep it; they made me throw my OJ away, <\/p>\n\n\n\n Another point us that mine came with both USB B & C charging ports; using USB B for the first charge of the bank was an incredible long period, 10’s of hours if I remember correctly. This could just be because its a big battery and has a lot to fill. <\/p>\n","protected":false},"excerpt":{"rendered":" I bought one of these a coujple of years ago and have always felt its recharge speed when using the solar panel was so slow as to make me question if it worked.
