I have a couple of Floureon brand (not a typo) and they seem fine. The
"bricks" which also do USB and laptop power up to 19 volt use lithium
batteries. I would steer clear of the 12 volt only type with a handle,
these use (small, low quality) lead acid batteries, at least in the
cheaper versions.

Is Floureon a decent brand, or just a made-up name like all the others?
Because I note there's:

44Wh for 28 quid, looks decent value? Though the reviews are a bit mixed.
