Yes the price for this is...mindboggling..even painful
But this one has 2.1 amps!! that 2x to 4x the speed you get from conventional car chargers!
Jet be careful - not every device can handle this and yes with some of the 0,5amp chargers you won't be able to charge even an old IPod less a newer Apple gizmo.
So yes this claims (absolutely) rightfully to be a High Speed Multi-Charger capable of getting you out of the ditch, you got yourself into, when you forgot to charge your stuff before getting down to the car.
