ok, but wish i'd bought bigger one
on 31 May 2013
the helium is ok, they claim it will charge the phone by 80% in practice this seems closer to 50-60%.
if i was buying again i'd get the air model offering up to 100% charge, or even the juicepack plus which offers up to 120%, so in practice maybe 1 full charge which would be useful.
