While I don't yet have one I plan to eventually but the Bluetti EB70 has higher capacity (and likely more weight, I didn't check) for the same price as the EB55 at the moment.

OK, an extra 2.2Kg for the extra capacity and at times weight can be a very important factor if going portable.
EDIT: Sorry, the EB70 has been discontinued, the last time I saw them Hardly-Normal had them on special but Bluetti had them cheaper. I had no idea they'd been discontinued, I'd hoped to eventually get myself the 1,000 watt unit.
