My Floureons look virtually identical to this. My main thought on the
one you linked to was that it was at the bottom end of the price range,
but seemed to claim unreasonably high capacity. So personally, I would
go with something "branded", also Amazon's no quibble replacement of
anything faulty is better and easier than eBay's. Now I come to think
about it, one of mine suffered an obvious switch failure in the first
month (lost its positive "click"), but sorted easily by Amazon.

They all seem to lie about capacity. For example this one:
https://www.amazon.co.uk/DBPOWER-800...dp/B013UBRZUS/
is 8000mAh. They can't possibly have a DC-DC converter in there for
300A starting current, so the cells must be in series up to at least 12V.
That means you'd think it would be 12V x 8000mAh = 96Wh, but the seller says
lower down it's 30Wh.

8000mAh x 3.7V cell voltage = 29.6Wh so they're just adding up the capacity
of the lithium cells, which isn't how watts, amps and volts work.
