cordless compressor for tires

My Dad has the Ideaworks one. It did fine for running his car tires from 25 to 32 psi- all 4. The battery was dead, but it comes with a cigar lighter plug, so worked well. Not sure what the upper pressure limit is though.

I have the Ryobi one.....already have a garage full of Ryobi Tools and 3 battery chargers so it was a no brainer for $20

Use it for my garden cart wheels, riding mower wheels, hand truck wheels but they are ALL low pressure----10 psi

I haven't even bothered trying it on my trailer tires.
Trailer tires 110 psi
Tried it on truck tires when I was re-adjusting rear tire psi for towing----going from 45 psi to 80 psi
NOPE>...got hot real quick

Might adjust 5 psi or so but I don;t worry/adjust if only 5 psi is needed.

BUT does handle those low pressure needs.

I keep a regular foot pump in the trailer. I had to use it to fill my spare once. It took about 15 minutes. The pump was hot, and both my legs were shot, but the batteries were still good. :B

Like Old Biscuit I have the Ryobi but since I'm only pumping to 44 for TV and 65 for TT, it works fine. Carry a high pressure bike pump as back up.

Many TC guys surf fish and have to air up/down on a regular basis and rely on portable high PSI units that won't overheat pumping 80+ lbs into a large tire.

I have a porter cable 18v compressor. Works great on the 30# Subaru and 50# trailer tires. Can't quite reach 80# for the truck tires on battery. Plugged in it will do one tire and then needs to rest for 20 minutes.

I have one of the battery ones. It can take a tire up 10 lbs okay, but is close to dead afterwards. I think it's more useful for things like garden carts where power isn't readily available. I also have a 12V cigarette lighter one - that's the one that actually gets used for the car and trailer.

Anyone using a Smitty Built 12v compressor? There's a unit on Amazon around the same price as the Viair, but double the CFM.

The pump looks okay...for what you are going to use it for. I have a little compressor that works off of 12V that I used to use for mine. It got to be a hassle to use so I bought a small electric compressor from Wally World with a tank that I use now. It fits in the tool box of my truck, easy to get out and plug in. I have a air hose that will reach all my tires. Most of the time I just plug my compressor into the power pedestal at the site. I have tried to get away from the battery operated stuff...batteries cost is the main reason.

I too bought the Ryobi. I can't remember exactly how much but it was under $30 without the battery and charger. I already had 3 chargers from other Ryobi tools i bought and several additional 4 amp batteries i bought. It works pretty good for bycicle and riding mower tires. I bought it for light duty work. Haven't used if on a vehicle tire yet. Probably okay for topping off a couple tires. It would probably take a while and need to cool down between multiple tires. There is a you tube video of someone putting 20 lbs of air in a car tire with one and took about 5 minutes. None of the battery powered inflator would be for heavy usage.

Few years ago I got a Harbor Freight inflator that came with a carrying case and clamps that hook to the car battery. I've been using It for the truck and camper. Then I bought a Sears Evolv pancake compressor that use around the house and can carry camping and run off the generator if I need to.
