This charger has been a great buy and a great deal. I have even been using it around the house if I’m busy and cannot sit next to a plug to charge my phone. It works extremely well and I couldn't be happier with my purchase. I love the light indicator that says the approximate charge level and it holds its charge for what I feel is a long time. I carry this with me all the time and it can fully charge my Samsung Galaxy A5 phone from near battery dead on one full charge – and there are still power left. We have a bigger portable charger but I wanted something smaller and less bulky to throw in my purse or to take with me when I’m out of the house. This has done exactly what I have wanted it to do - quickly charge my phone while on the move. I'd surely recommend this to anyone looking for that extra battery back up. It's given me the freedom to use my devices without being tethered to a wall charger a lot. I also love that it comes with a carrying case that makes it so convenient to carry around.
