Two-Inflator Kit, 4500 mAh and 4000 mAh
The entry kit: a 4500 mAh pump and a 4000 mAh pump, one for each car.

Roadside Kits
Twenty-eight car tyres on a single charge is the figure that matters here, because it is what lets a pump sit in a boot for a year and still be useful. The larger unit also takes a 12 volt cord from the car socket as a fallback. The smaller one covers thirteen tyres and stays light enough to carry to a bicycle.
