Any electrical boffins - Vape DC power capailities

Im running a Vape DC system on both mine and was hoping for some electrickery advice...
I want to hard-wire up a loom for a pair of heated gloves that apparently uses around 2 amp/hour.
So does any one know how much power a Vape DC creates - which I think is measured in watts - but how do you convert that to amps/hour back into the battery??
And will that still be sufficient to power things like the gloves, a sat-nav, a Mychron rev counter gizmo and be able to charge a phone.
I have wired in a seperate fused loom to power the Mychron and a Usb outlet - which is independent of the scooters DC loom as if there was any issues at least I know the scooters loom is entirely seperate...
The gloves have their own fused loom tp gp directly to the battery as I'm told they cant be wired via a USB port as they cant provide enough power??
And what size battery amp/hour should I really be fitting??
Its all a bit of a minefield so any help or recommendations would be appreciated
TIA....
