[This post has been updated to reflect the fact that Scosche's reVOLT charger only comes with two ports]
There seems to be some discrepancy in talent between the naming and the product departments at Scosche: the former can come up with a product name like “reVOLT pro h2,” and the latter with a product like, well, the product inside the package with “reVOLT pro h4” written on the outside. Revolting nomenclature aside, the pro h2 is a charger which can juice up to two iPads at the same time, via its duo of 10W (2.1A) USB ports.
The charger also packs Scosche’s two-in-one charger cable, which has a large USB plug at one end and a 30-pin dock connector at the other, the dock connector can be opened up to reveal a micro-USB plug inside.
Charging two iPads at once might seem silly, but many homes have more than one iPad, and I’d rather carry a multi-USB charger which can work with all my devices rather than have to carry an extra one just for my iPad.
