I bought a MagSafe Duo Charger about 2 months ago and have only unplugged it once last week. After I plugged it back in, it has been charging my Apple Watch super slowly (about 8% in 2 hours). What’s the problem?

All power adapters have different ratings for the amount and rate of power delivery. The MagSafe Duo Charger requires the following ratings to deliver faster wireless charging:
To use both the iPhone and Watch charger at the same time, the MagSafe Duo Charger requires at least 15W (5V/3A or 9V/1.67A), but this will result in slower charging.

The power adapter mentioned above are also made by Apple, but they provide more amps for the use with the MagSafe Duo Charger.
Does your Apple Watch charge faster, if you use the charging adapter that came with the Apple Watch, and are you using the 5V/1A power adapter, that used to come with the older iPhone models, for example?
Thanks a lot for the info! I’ve been using a 5V/3A or 9V/2.22A. I just tried charging my watch this morning and it turned out to be fine once again. I guess I’ll never know why it was so slow in the past few days…
No. I’m using Apple cable and plug. Everything original.
Sorry I mean I’m using the original cable and plug for my iPad.
You're welcome 🙂
Let's hope, it was just a glitch.
