This is the worst charger I can imagine, the connection is extremely bad, every two or three weeks I get a message on the mobile app "Your MiniProV2 is currently offline, please check the connection" and the worst is, I plug in at night and start charging and after an hour or so it stops charging , and when I check the EO app in my phone it displays the above message. I have a lost confidence on this product and I don't recommend it to anyone. I have contacted the company all they tell you is to check the connection and swich on the power as it jumps off in such a situation. They can't be bothered to source of the problem and fix it . It could be connection is the inherent problem of the product. It is better to spend a bit more and get more reliable charger. This is not a reliable charger at all. Thanks
