Cordless Air Inflator
 

Tired of having to bring anything needing air to a power outlet.
Thought I'd try one of these.

I already have the 3amp battery and charger for my cordless drill.
Bike tire needs a top off..just bring it to the bike..it only weighs a couple pounds.
Works great. :)
Comes with a 12v adapter, Presta valve fitting, and other fittings.

I have a Ryobi one of those. It is OK for bike tires but definitely not for a car or motorcycle. It does not move much air.
