Today we're going to take a look at a Bulldog Wenches portable air compressor. Now this is a heavy duty 150 PSI air compressor. It's going to allow you to air up your tires or anything else you might need on the go. We have this 16 and a half foot, coiled up hose, so you're gonna be able to reach all four tires if need be; if you're in an emergency situation, and you need to get all four tires aired up. That, along with our 10 foot power cable. How it gets its power is that we have these two clamps.
We have one for the positive, one for the negative side of our car battery, so we can hook it up to there to draw our power.That's also gonna be convenient for emergency situations, where you might be in the middle of nowhere, and all the power you have is from your battery. We're also gonna have this tire pressure gage on our hose. It's gonna measure our PSI for us, to make sure we get the correct tire pressure reading.Now, the air compressor is also gonna work with all of your bike tires, whether you have a mountain bike like this, or even a motorcycle. It's also gonna work for those as well. Now, the compressor is also gonna come with three different attachments for various inflation needs that you might have, including a needle, so you can air up your sports equipment.When you're done with whatever you need to inflate, you can pack it up in a convenient carrying bag to make for easy storage.
Now, let's go ahead and hook it up, and show you how it works. Now, we've got our hood open, so we'll go ahead and take off the cap of our positive side of the battery . set that to the side. We're gonna go negative first. So, we're gonna hook it up to this side, our ground.
And we'll go right here on our positive side.We can go ahead and connect our air hose to our valve stem. How it's gonna work is we're gonna push down on the valve stem. There's actually gonna be threads on the inside of this attachment. We're just gonna spin it on and you are gonna hear air leak out a bit at first, but you just keep tightening it until you don't hear the air coming out anymore. And then, it's gonna hold a constant pressure.
So, we'll begin tightening it, and then you'll hear the air, you just keep going. Now it's fully on. With our tire pressure gage, we're gonna have a constant reading, even when the compressor is not turned on. As long as that is tightened down on the valve stem, we're gonna have a constant reading.We can se we're a little bit low on air, so we're gonna come down to the air compressor, there's going to be an on, off switch on this back side . right there. So, we'll go ahead and flip it on and we'll begin airing it up. So now we're gonna see how that dial slowly goes up. We're gonna get it to the correct reading that the manufacturer of this truck wants us to have the tire pressure at.Now, what's also nice is that while our air compressor is running like that, the bottom side of our tray is gonna have these nice, rubber knobs where the platform is sitting on, and it's basically gonna absorb a lot of the vibration that you might experience with an air compressor. You kind of see that it will stay put. We're gonna turn it back on. It's absorbing that impact right there, and it's not gonna move around at all while we're airing up our tire or anything else.Now, we have the correct PSI on our tires, so we're gonna go ahead and remove it. Then, we can repeat this process for the other tires. Now with all that being said, that's gonna do it for a look at a Bulldog Wench portable air compressor.

Ratings & Reviews
Worked well for filling bike tires. I loved the automatic shutoff at a set pressure. First time I tried to fill one of my trailer tires, though, it started smoking. Wiring and plugs were fine (not even warm), but the pump couldn't take my trailer tire from 65 to 80 PSI before smoking-out. I've seen mention that it's meant to run in 10-min cycles... this thing is already has auto-shutoff so if it needs cool-down time, it should be configured to do that automatically rather than a user being expected to keep a timer on it.
Compressor is dead now after trying to top-off 1 1/2 trailer tires - it started leaking the air internally.
Works great for bicycle tires and sports balls, took a long time to bring a spare tire for a trailer up to pressure.
Unit performed well the first time it was used. Second time the feature to preset the pressure for auto shut off could not be set (blank screen). Contacted customer service twice during warranty period to request a replacement. No response from Bulldog customer service. Very disappointed. Waste of money.
Works as advertised, left a bunch of air out of one of my trailer tires and the pump was able to put it right back to 75 psi without any trouble. Not totally sold on the thread on air hose but I’ll get used to it. Nice and compact too
Quality tire compressor. Bought for trailer wheels that require 65 psi pressure. Inflates tires pretty quickly. Heats up, but not much and cools down quickly. Convenient long hose and long wire. A small minus - the thread for the air filter is clogged with paint. Before screwing on the filter, it must be cleaned.
The first time I used this compressor it blew a fuse in my truck. I replaced it and then it worked long enough to finish with that tire. I chalked it up as just "one of those things". Next time I tried to use it a few weeks later I was camping and needed to get my travel trailer tires ready to move. The compressor blew the fuse and all the spares I had and still did not have the first tire to a road worthy pressure and I had to pull the trailer with low tires. I emailed the company that made it to complain and they never even replied. I probably should have contacted etrailer but I didn't. I liked the features of the compressor but it doesn't do any good if it constantly blows fuses.
After owning this unit for almost One Year i must admit i hadn't used it for anything too big until recently. it works fine for my bicycle tires, the tires on my Hand Trucks and other "small" tires and such however whether this was a misunderstanding on my part or whether the specs were a bit ambiguous i'm NOT sure but when i tried to air up a low tire on my pickup this Air Compressor would hardly air up my tire more than a few PSI rather than the 25-30 PSI i needed to re-inflate my tire. i own a 1 Ton, CrewCab Dually and my tire size is 235/75 R16. The tires require 80 PSI and i was barely able to get the ONE low tire beyond approximately 55 PSI and i found the Cigarette Lighter plug on this unit got QUITE hot in the process. after contacting the Manufacturer i found out this little unit was NOT intended for any types of Heavy Duty tires, which would include the 100 PSI required to properly inflate the tires on my RV either, even thought in the ad it shows and stated it WILL air up a Truck Tire. so if you are needing something to handle a Truck Tire i would say this unit would NOT be a good choice for that.
I set it to 80 PSI and started it. It shut off when it was done. I was happy with the performance. It was accurate according to my digital tire pressure gauge.
I bought this to use on my horse trailer. I needed something that could do up to 100# psi when traveling. I spoke with Kim at etrailer and she felt it would do what I wanted. She assured me if not, she would assist me in returning it at no charge. Well I can assure you it does the job and very fast. Just hook it up to the batteries on the trailer. There's plenty of cord to reach the tires and took it about 1 minute to get to the needed pressure. My trailer is a tri-axle approximately 40' long. Easy peazy. No more worries about finding someplace I can get to when a tire is low. Just pull in to a rest stop and fill the tire.
Poorly designed and cheap.
About $10 cheaper than the [online] model. Good value for the money. I'm able to use it on my Jeep Wrangler with 35 PSI tires, my work truck with 80 PSI tires and my work trailer with 110 PSI tires. Great to have when those pesky TPM warnings pop-up. The unit and the metal fixtures do get hot after use, so be careful when handling or trying to store it soon after use.
Bulldog BDW41002 Portable Air Compressor
Positives - Motor and pump appear to be well made. Hose doesn't get stiff and kink in cold. Relatively quiet. Rubber feet under isolation tray work well to prevent "walking." Added 15 PSI to 33 inch tires in 3.5 minutes.
Negatives - Usability is lacking. Battery clamps are weak and wimpy. I zip-tied the cable to the battery compartment to prevent clamps falling off and shorting to ground. ON-OFF switch on unit makes use awkward. First, I screw the hose to the tire valve. Then, I walk back to the unit to turn it on. Then I walk back to the tire to monitor air pressure. Then, I walk back to the unit to turn it off. Finally, I walk back to the tire to remove the hose. If my calibrated pressure gauge says pressure is off, I repeat the process.
Wish list - Longer battery cable with stronger clamps. Shorter air hose that shuts off air when removed so compressor doesn't burn out. Either a better gauge or no gauge. Fix website description to remove reference to over-inflate button on back of of gauge. Mine has no such button.
Atta-boy/girl to Chris R and Hally C for great customer service.
It's scary to be on the road and have a tire pressure monitor give a low pressure reading. It's worse when you stop at the next two or three gas stations along the way, and none of the air pumps go up to the 80 psi that your camper needs. (Bite your fingernails till you reach a truck stop.) This pump is easy to use, great for topping off the tires before the trip. It's small enough to pack along, and it's powerful enough to do what most gas station air pumps won't do. We got the version that clamps onto the battery, so we can use the vehicle's battery or the camper's battery, whichever is more accessible.
Works like a charm. Easy to stow away.
The first time I used it meet my expectations and looks like it will meet my compressor needs, a car, truck and travel trailer, w/spares. Very impressed with its first use and how quiet it was.
Works well. Only reason not 5 stars is the power cord should be another 2-3' longer.
This heavy duty air compressor was very reasonably priced and is a must for anyone with a travel trailer. Working with your 12volt battery, It is fast and easy to top tires off in your driveway or at the campground before taking off on a trip. Etrailer has great products they stand behind, shipping is always fast and prices are great too.

Used 4 times last year worked great, this year the screw on valve went bad, I replaced with a regular air chuck, pump runs but produces very little pressure. Doesnt seem to last very long.
What a little Gem of a compressor! Took me a minute to figure out I had to screw the piece ON TO the tire valve but than it worked perfectly! Can't wait to try it on a blow up kayak.

Enjoy your first kayaking trip! The compressor is definitely going to help get everything set up much faster.
