So as the price had been reduced, I pulled the trigger on the SliceCharge2. It’s not too bad and is charging my AirPods, XS Max and AW4 as i speak. Positioning the devices is tricky though. The phone is easy but the watch and AirPods need to be positioned carefully.
I have found the best way is to position the devices diagonally.
It’s not perfect but reduces charging from three chargers to one.
Actually I need to revise my review. The phone and AirPods charged all the way to 100% but the watch stopped charging at 53%. Even though the charge icon on the watch was showing, the watch would not charge any further. Switched to my Apple puck and the watch charged all the way to 100% so it looks as if my unit is faulty. I have requested a replacement.
