## Description

## NOCO AIR20: portable air compressor 100 PSI (12V)

Made for 4x4s, pick-ups, motorhomes and trailers on big tyres: it reaches 6.9 bar (100 PSI), moves 47 L/min and handles tyres up to 35 inches. A 205/65R16 tyre goes from 0 to 40 PSI in about 2.5 minutes, the quickest figure in the family.
The trade-off is an 18 A working draw (22 A peak), so it does not use the lighter socket: it clamps onto the battery via a 6 m lead. If you drive an ordinary car and prefer the socket, the AIR10 or AIR15 are handier.
It is also the heaviest of the three at 3.09 kg, while keeping auto shut-off, manual mode and the 60-lumen torch.

### Common questions

Why doesn’t it use the lighter socket?
Because it draws up to 22 A; the guide connects it directly to the 12 V battery with clamps and specifies a 25 A fuse.
Will it reach all four wheels of a motorhome?
The power lead is 6 m long and the hose 0.9 m, so you can walk round the vehicle without moving the clamps.
Is it worth it over the AIR15?
If your tyres are larger than 33 inches or you need more than 5.5 bar, yes: the AIR20 goes to 35 inches and 6.9 bar. For an SUV happy with the lighter socket, the AIR15 will do.
