I had a reply directly from Anker who said it will work.
However I have a problem with my Apple Watch series 4 charging on the device.
When I set it on the charging puck it doesn’t register as charging. If I leave it some time then it will all of a sudden kick in and ping at me that it’s charging, then the Watch will lock and the screen will go dark, then it’ll light up and ping at me again that it’s charging. And this will repeat indefinitely until I take it off.
Weirdly if I turn my watch off and then place it on the puck it will turn my watch on so so that indicates it
knows there’s power there? Sometimes that’s enough for it to start working normally, sometimes it’s note.
Sometimes it works first time no problem.
I’ve tried with bedside mode on and off. Neither of these settings seem to make a difference.
I’ll email Anker about this and see what they say.
