STAY AWAY! In no way does it do what it claims. I received it, charged it, and after a few days at the beach, it couldn't inflate a small children's mattress. I recharged it and with great difficulty, it inflated it. I am sending it back and they tell me that it has no defect. I charge it on Saturday and by Wednesday it is uncharged and without the power to do anything. It's as if you unplug it and immediately inflate what you want; if that were the case, it wouldn't have a battery but a plug. Unacceptable both the product and the store that sent it back without testing it, despite the fact that I fully explained the problem with the battery and its inability to inflate a simple children's toy.
