PSU 65W+ USB C Battery Bank for Dell XPS 13

I'm doing some research, so I may find something but it often proves valuble to mine the bit-tech knowledge base:

Can anyone recommend a USB C battery bank capable of out-putting 65W or more to charge a XPS 13 laptop on the go? The trick here is not to use Amazon - they won't deliver battery banks to the island; not even wireless earbuds in a charging case!!

So likely Ebay or some such, whilst avoiding the chinesium fire hazards.

Any experience/knowledge to share?

Anker are good quality, I have their model 737 power bank (140W output), but they also do a model 537 (65W) version.
If you want a hard case for it and a couple of cables, get the one for Anker's "Soundcore 2" bluetooth speaker.
Currys stock the 737, if that helps.
Which island are you referring to?

 

Thanks for that, bud.

My own personal island, of course!

Or the isle of wight... One of those

 

The big boy looks a bit chunky, both for my needs and my wallet, so I've gone for the 65 watt 537 model - it has dual USB C ports so my XPS will charge at 45 watts and my phone can suck down 20 watts.
