^ Claims 30V, making it seem as though it has 8 x Li-Ion cells in it or a voltage boost circuit so no, it's not the right pack for pumping an air mattress assuming the pump is 12V spec'd.
I'd get an R/C toy pack with 4 Li-Ion 18650 cells in it instead, presuming you want low weight to energy density ratio for camping, or for more stationary uses a 4 or 7AH, 12V SLA battery, depending on how much current the pump draws and for how long till the mattress is inflated.
anyone has the experience to tell us if this can be used to pump an air mattress a few times maybe at least 2 times.
