Cool Stuff
GMC Envoy

What is It?
Auxiliary air pump

What We Like
Blow up those lake toys without making your cheeks red or reinflate tires after a day playing on the sand dunes. The kit includes a hose long enough to reach the front tires and accessory nozzles to fill everything from bike tires to basketballs.

What We Don't Like
The pump's small capacity and lack of a storage tank means it'll take a long time to air up tires or large inflatables.

How It Works
Remove the plastic cover on the passenger side of the cargo area, turn the ignition key to the accessory position, and depress the air compressor switch.
