300P is a larger more powerful portable tire inflator kit that is capable of inflating up to 33-inch tires easily by simply clamping the power leads to your battery, connecting the tire chuck to the valve stem, and turning the unit on. Tire pressure can be checked using the 5-in-1 Inflator/Deflator inline pressure gauge. This is the portable compressor we use and trust.
Please note: The air hose supplied with this kit may become brittle from prolonged exposure to UV/sunlight. – Stow when not in use. Never allow the hose to come into contact with the head of the compressor during use (melting hazard). The use of the included air hose is not recommended in sub-zero or freezing conditions. The 300P does not work with Presta bicycle valves unless used with a Presta Valve Adapter.
