I bought it without much consideration, for a small receiver that has a very small battery. I had to buy a type-c / micro cable. You have to constantly poke the button, so that this squalor would recharge the receiver. A friend wanted to recharge the phone while she was visiting, so in an hour he did not charge even 5% with contactless charging. For this money you can take a baur-bank much more interesting. For example from ROMOSS.
