Apple Watch Ultra not charging

Perhaps the Belkin charger is defective? Since it clearly charges fine on the Apple charging puck, the issue is with the Belkin charger. I would reach out to Belkin for help with their charger.

One thing I would check however, is if there is by chance any covering over the watch puck on the Belkin charger? It could be a clear or white cover, which might need to be removed.

It is a really nice 3 in 1 charging stand!

I'm a bandaholic and have added a slew of new bands for my Ultra Watch. I've purchased the $300 Pure T2 Titanium band from NOMAD (they have some amazing bands, btw), which is beautiful. But the band you see on my Ultra in the photo is a Titanium band from a company called LDFAS. It costs $70 and has the simplest link adjustment system by simply pushing a button down on the underside of the link, remove the link and put the band back together.

The Titanium matches the watch color perfectly and is an amazing value for $70. It's a brand new design from them and I really like it.

Here's the expensive Nomad band:

And another Nomad band I really like is called the Rugged Sport band, which I like so much, I have it coming in Orange (hopefully next week after ordering it a couple months ago).

The Rugged band is made of FKM Fluoroelastomer (the same material Apple uses in their Sport Bands)and is just a perfect compliment to Apple Watch Ultra.

This is good to know. I'd still contact Belkin and ask for help with their charger. We know your Ultra charges. We know it doesn't on the Belkin. This is clearly a Belkin issue.

To contrast, I have the newest generation 3 in 1 charger from Insignia. It absolutely charges my Apple Watch Ultra, because I use it every day.

It has a fan you can choose to turn on when charging your phone to keep it cool too. Though I don't seem to need to use it. It is whisper quiet.

Here are a couple pics:

Does it charge with the original puck?

If yes then get a refund for the Belkin

So we have worked out that the Belkin is working but not compatible with Ultra.

I'd likely choose the refund and buy something else. As I posted and linked, the Insignia positively works with my Apple Watch Ultra.

Yes. And it's certified "Made for MagSafe" and "Made for Apple Watch."
