Amp Draw: 27 Amps Review: Great tire inflator. Quiet, fast, small and easy to pack. - I was wanting a better quality tire inflator to carry in my Travel Trailer. It had to easily inflate my trailer tires that are rated for 80psig. I read over the reviews of several inflators and decided on the 300P. Put it to the test yesterday. I am very pleased. Had no problem handling the 80psi tires. Pumped one that was at 70 psi up to 80 in about 65 seconds. The battery clips are plenty large enough to grab onto a battery post connector. My trailer batteries are located front underside of my 34 foot 5th wheel center compartment. With electric wire and coil air hose, I reached tires with no excessive stretching. The air hose to valve stem clamp is very good and tight. No air loss and would be much easier than the screw on fittings others come with. This unit also has the "Air release" feature to let out excess pressure. The air gauge is a good quality. The pump is much quieter than I thought it would be. Comes with a very good carrying bag that has room to include any special fittings you may need. I did have my trailer plugged into electric power when using the inflator. The write up on it stated to have vehicle running while using. This is to give the 12V a little extra boost. This is understandable. The in-line electrical fuse would make it very easy to replace fuse if needed. I will be buying an extra fuse to carry just in case. Review: simple, fast, a little noise - the unit works perfectly for inflating tires. I use this on my old pickup that has aluminum wheels and being 10 years old tends to lose air. I could replace tires and maybe that would solve it (but the tires are in very good shape) and then after replacing them find it is the wheels... in either case not worth investing in... easier to use this [excellent] 12v tire pump. will also move it to the RV when that is being used (just in case there is a problem). By all means, this unit pumps up the 16 or 18 inch tires from 25 or 26 lbs to 44 lbs pretty quick. Nice feature is the pressure gauge is near the inflation end... easy reading. Comes with all the ends you might need... if you are looking at a portable 12v air compressor... look closely at this one ## Features - Tire Inflator Kit: Stay prepared at all times with the VIAIR 300P Compressor.

Google RV Geeks Winterizing and go to t=40 seconds to see their solution when using a 150 PSI Viair compressor to blow out their RV water lines. (Sorry, Amazon won't let me post the link here). **Q: It states it has a 1 year warranty! Yet, no returns. How does the warranty work?** A: I don't know. It's the seller's policy. You are allowed to email the seller to get the details. Keep clicking on the seller's product section to find the contact link. BTW, this is a heavy duty pump. I had a tire with about 30# and within seconds, it got up to 36#. I recommend the VIAIR 300P. **Q: I need to 'top off' my rv tires up to 125 psi. from anyone with experience... will this compressor work? if you don't know, please don't answer.** A: Hello, We recommend the 400P-Auto or 400P-RV since the 300P's gauge will only show up to 100psi. Let us know if you have any other questions. Thanks, Viair Corp. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great tire inflator.

This VIAIR compressor is soo much faster and quieter. Also it appears to be solidly built with mostly metal parts. The air hose attaches to a standard pneumatic fitting which means if the air hose gets damaged or leaks overtime, it will be easy to replace it with any off the shelf pneumatic air hose. It will fit behind the rear seat storage area of a Tacoma Double Cab (2010) if you rearrange the accessory bag and place the air hose on top of the compressor in the main compartment of the bag. The only problem I found with this unit is that the air hose took a lot of force to get it to connect to the compressor fitting. Hopefully it will get easier with time. ## Frequently Bought Together - VIAIR 300P - 30033 Tire Inflator Portable Offroad Air Compressor for Truck & SUV, 12V On/Off Road Tire Pump Air Compressor Portable Heavy Duty 150 PSI - ALL-TOP Adjustable Auto-Stop Tire Deflator Valve Kit (10-30 PSI) 4 PCS Screw-on Tyre Air Down Tool for Offroad 4x4 (with 5 Valve caps) - Boulder Tools - Compact Tire Repair kit with Molle Storage Pouch.
