Wagan 12V Mighty Impact Wrench
Strength
With 271 feet-pounds of max torque, the Mighty Impact Wrench can manage to remove lug nuts off of most passenger vehicles, even those neglected models. With a no-load speed of up to 5000 rpm, the Mighty Impact Wrench has no trouble spinning off those loosened lug nuts and assisting you in putting them back on. Even if you are lacking in strength, the Mighty Impact Wrench has all of the muscle you need to get the job done!
Ergonomic Grip is easy to use
The shape of the 12V Mighty Impact Wrench lends itself to ease of use by virtually anybody. The body and grip have a rubberized texture and are small enough to be gripped by the daintiest of hands, yet big enough to handle for large handed individuals.

Use for Roadside Emergencies
You are driving, suddenly the vehicle starts to handle oddly, sluggishly. Panicked, you pull over to the shoulder only to find out that the tire is flat. You have a spare tire, but how do you put it on? Remove the convenient 12V Wagan Tech Mighty Impact Wrench case from your trunk (or under the seat), open it up, take out the contents and get to work! Within a short amount of time, you'll be safely back on the road.
12v power from your vehicle
The grip has a rubberized texture and is small enough to be gripped by the daintiest of hands, yet large enough to handle large handed individuals. Simply plug in to your vehicle's cigarette lighter socket to use.
Everything in 1 Convenient Case
The molded case neatly stores all of the necessary tools to remove lug nuts: the Mighty Impact Wrench, spare fuses, and two double sided sockets.
Easy to Control
The 12v Mighty Impact Wrench is ergonomic in design and the 3 position switch (Forward > Lock > Reverse) is intuitively placed near the grip for easy direction changes.
Bubble Level Indicator
The integrated Bubble Level Indicator will help to ensure that the 12V Mighty Impact Wrench is square to the lug nuts to lessen the chance of rounding them.
Accessories Included
Two sockets and two fuses are included with the 12V Mighty Impact Wrench. Each socket contains two different sizes making a total of four different size lug nuts that are able to be removed by the 12V Mighty Impact Wrench.
Convenient Case
With an integrated handle in the locking molded case, it is easy to keep the 12V Mighty Impact Wrench stored in the trunk of your vehicle ready to use when you need it.

wasted money. Would not work good enough to turn a lug nut. So tried to contact seller, they sent a video of how to use it. Claimed tool had to be level to work properly. Got tired of trying to explain issues and tossed it in the trash and stayed with 4way.

I bought it because this was the least expensive option and came with additional sizers. I used it on my sedan and it struggled at first to take the lug nuts off but it did work. It gets hot faster, the quality ( for which I took few stars off) is marginal at best. I don’t anticipate it lasting with regular use. The built in light feature seems useless as well. Its Avery did light poorly placed at the bottom. I kept it because it does work and only for emergency use.

It works.It fits in my truck box or car trunk.Do not know how it would hold up with every day use. You probably need something stronger for that. However, I have used it several times, and it worked. Do not expect it to sound or work like a regular impact wrench. If you can read, read the directions and follow them and it will work.It was a good price for an emergency tool.

I wanted some emergency equipment for our motorhome. We have a spare wheel but we’ve had to wait hours for roadside assistance, if it’s available at all. I just don’t want to be stuck somewhere isolated (maybe where there’s no cell signal to call for help!) with a flat tire. So, I bought this wrench so I can change a wheel by myself. I tried to remove lug nuts with a long-handled wrench but couldn’t break the lug nut free. Then I tried this 12V wrench and voila! It removed the nuts like a champ. No arm-breaking recoil (torque) either. I haven’t useed the wrench yet in an emergency situation but I’m confident I can change a wheel by myself with this tool. PS: you can but shouldn’t use it to reinstall lug nuts - it’s powerful enough that you could strip the threads. I use a torque wrench for that. Between these two tools, I think I’m covered!

How to use this Impact wrench!!! I learned a lesson today, the impact wrench WILL NOT WORK work if you PUSH into the bolt you are trying to remove!!!! Instead put the socket on the bolt securely, then squeeze the trigger. The unit will spin up then go clank!, To remove my tire lug, I had repeat this 6x but each time I saw the lug turning. NOTE: if you use this on a flat, clank it 3x per lug then jack your car up a bit so the tire is either on the ground lightly or above ground or use your tire lug wrench again with the tire off the ground. If you have the weight of the car on the flat tire, you could snap or bend the lug nuts and or damage your rim!!! This supposedly has about 100lb more torque than the Kawasaki which I purchased first, and I think it does have some extra power as the Kaw. did not loosen my lug at all, BTW I also noticed I pushed the wrench into my bolt for some reason and I thought I broke it.... Moral of the story, put the socket on the bolt/lug but do not push into or down into the lug/bolt.I learned the pushing stops it by trying to remove the bolt on my motorcycle fork (if you need to replace your seals this makes it a piece of cake)! I pushed down and nothing was happening, luckily I took pressure off and then it worked, that's how I figured it out!!! I bet most of the I didn't work people made the same mistake as I just returned the Kawasaki for the same reason!!!

Purchased this tool last week and just used it yesterday to change 4 tires on my car. Super easy to use, even if your are a beginner like myself in DIY repair jobs. My lug nuts were bolted tight by someone who installed my winter tires on. He failed to use anti seize, thus we couldn't get the lug nuts out manually. Since we wanted to change our tires ourselves this season and to do other work around the wheel body frame of our car, we decided to search Amazon and found this nice little Impact wrench.Wagan, the company, is a US based company and after researching them, we found that they do make high performance automotive tools and are described as a company who take great pride in their work and are quite "honorable" to their commitments.Overall it took us less than an hour to change our tires, but this is with some extra work that we performed around the body frame where the tires sit.Going to the mechanic to change your tires will probably cost you anywhere between $30 - $75 and plus depending on the shop and the installation process. A one time purchase of this impact wrench makes it a worthwhile investment to an automobile owner.It also come in a convenient carrying case which is super light (impact wrench included) to carry and take with you or just keep in the back of your car trunk.The only slight problem with this tool that we discovered is, you have to plug it in your cigarette lighter and have your car engine on at all times for this tool to work. Otherwise, your battery will drain. Also, if you have a battery booster pack with a 12V plug in it, DO NOT use this Impact wrench with it. We did and quickly found out that it drained the booster pretty fast after removing 4 lug nuts.Overall, we give this tool a 5 out of 5. It does the job, its super light weight and super easy to use. Yes, we do recommend this tool for any DIY car owner or general auto mechanic.

The device works, but not as effective as I would like. This 12V impact wrench best operated with car running to supply 14V to make this product work better. At one impact per second or so, it takes a few seconds to wack wheel nut loose. Bottom line, it works, but for practical reasons, if it takes time to deal with the cable and its hookup, and throw in the one impact per second operation, it is just too much fuss with little reward. Better to have a breaker bar and appropriate lug nut size socket to leave in car for more efficiency. The short ineffective lug wrench supplied with most cars easily compensated by a good long Craftsman breaker bar with appropriate socket. With no assurance of how tight the lugs are when reinstalling them, a real wrench is best used anyway after using this impact wrench. However, the item is a keeper for me as home mechanic to deal with certain suspension work and long reach hardware. I would not recommend this product to the average buyer eyeing this product as an alternative to normal methods.6/2012: Now comes a positive update. The tool is very useful when time comes to perform car maintenance beyond working at one wheel. When rotating tires, this impact wrench amplifies its advantage compared to single wheel work scenario. Rotating tires or removing multple wheels to perform brake work are times when this tool really shines. There is the need to use a breaker bar or torque wrench to tighten the lugs with proper torque. Counting number of impacts during tightening process may not generate consistent tightening torque from lug to lug. But this tool works!
