only charges one at a time. 5 Star purchase all the way. Easy to install with 2 people. Thank you seller ?? I have wide feet and i just ordered my normal size. I received the Axloie pair of wireless earbuds today. Looked solid construction but smooth swivel and click-stop adustment for users convenience. It didnt dig into my thighs or my groin area like I thought it would. I can?t feel the memory foam but they?re a good looking slipper that seems to be well made. 4 stars because I havent tried the go pro mount
