I love this charging station. It lives on my desk and it gets used all day every day with every device I can think of charges my phone, my MacBook Pro, my gaming, laptop, headphones, etc and it doesn’t quickly. I’ve had no problems with it whatsoever, and I love the retracting cables, and a little adhesive pad that keeps it in place on the desk. Well done!
