Hi, you could try the Baseus Powerbank:

See question ’ Which USB power bank should I get?’
Yep. I got an email back from Dieter at SongerbirdFX, suggesting the same. He said that in his experience, Anker don’t support 12v over PD. He was surprised the OT even booted. I’ve ordered the Baseus.
The 65W model?
Wondering if the 22W version would work for my DT
Yes.

If it delivers 1.5A@12V it is okay for ST (in my experience) so it should be fine for DT which I hear draws less.

I’ ve got the 65 W version because it powers my Maschine+ using a 15 V PD Birdcord, too. And yes, it’s a little bit bulkier.
EDIT: I don’t like running power supplies at their specified limits, so the 22 W version (with only nominal 10.000 mAh!) doesn’t suit my needs.
I use xiaomi mi powerbank pro 3 with pd birdcord. Works flawlessly and wasn’t to expensive.
