I got this after our two solar puffs proved invaluable after a five day power outage. I didn’t test it immediately and had trouble charging it: after sometime in daylight it provided a bit of a charge but only a couple of %. When we had our next power cut it didn’t work, I put it down to me not having positioned it correctly in the sun. Twice again this has happened and I sit in another power cut unable to charge my phone. Either we simply don’t get enough sunlight to charge it or something is wrong with the cables/cells but now it doesn’t even turn on. For the price paid, I’m very disappointed, we love the solar puffs.
