Why are you going to the reviews for chargers on Amazon? It’s surely reliable enough to be on the site. Idk I bought them like a week ago and it’s already asking me to send a review. Newsflash: they work. Now I’m not sitting by my devices with a stopwatch but things seem to charge relatively quickly and both ports can work simultaneously. Get it or don’t I’m not getting paid for this so I don’t care. Hope this helps ✌️
