Suggestions please: battery-powered projector

Worried_fool

I am swamped under thousands of unsuitable listings on Ebay and Amazon: can you suggest something?

I am looking for a projector that (i) can play films and so forth stored on a USB flash drive; (ii) can be used when mains electricity is not available, so would need to run from rechargable batteries; a USB power bank, or similar (not a car battery). I would like to keep the cost down and buy second-hand, but there seem to be vast numbers of cheap new products, mostly without reviews (but those that have been reviewed appear to be rubbish).

What should I look for?

The XGIMI Halo+ gets good reviews. I had one of their other models for a while and it was pretty impressive. But, and this can be important, not great unless it was in a dark environment.

The battery won't last all that long, you might get one movie out of it.
