LANNERET Cordless Electric Impact Wrench Kit,Double Power(Battery-Powered or Corded-Electric),300 ft-lbs 400 N.M Torque,1/2 Inch 12 Volts Portable Car Impact Wrench,Digital Display Torque Adjustable

Works fine. Been using a 12v car plug powered impact wrench. Most of these impact wrenches do not have adjustable torque settings, like this one. You can screw bolts back in with a torque of minimum 100 lbs up to 300. And, you can unscrew bolts using 100 to 300 lbs of adjustable torque. Battery works good. Haven't used the 12v plug adapter yet. The 400nm translates to the 300 lb max. 95% of bolts come off with this much torque. The other 5%, you can use a $12 breaker bar.

I did not expect the way it works but .... it works well to get the overtighten nuts out and it has a digitally set torque that actually works well if you handle the tool properly: straight and not pushing on it. Just let it do its job.Now, this is not the same behavior as the other power impact wrenches you might have seen. It literally impacts like a hammer when you try to get in or out the nut or bolt. Bang Bang Bang ... until it needs to rest or it did reach the selected torque or it quickly unscrew the bolt with little resistance. No idea how long the tool will last, but it has already paid for itself with the last repair I did using it.Still, it is convenient and it does the job. It works cordless, plugged in the 12V outlet of the car, or with an adapter 115V->12V that I have purchased for other 12V devices. Therefore I keep it. I do not think I will purchase another battery for it, unless it is cheap. The battery lasts long enough, and if it eventually dies, I still can use the tool with the 12V adapter.

The media could not be loaded. 12/5/2020 Update:I had to go to the junk yard and took this with me to make things easier. I was removing parts for a 2006 300 and when trying to use the Impact wrench would just spin and not actually hit like normal. I tried a few times and still would not work. It did say that the battery was low so I gave up and decided to do it by hand. I then tried again with another bolt to just try again and it worked. I was able to remove a few more bolts without any issue. I then went back to trying to remove some bolts from under the vehicle, then realized that if I put pressure on the impact wrench facing up it just spins and does not create the impact. So If you are planning on using this under a vehicle facing up it wont work for you.This is a nice Impact wrench for the price. It’s not like a normal impact wrench that hits continually until it’s loose. It appears to spin internally first for a second or two then applies the hit. So far have been able to remove and tighten lug nuts on my 2005 300 and 2001 Lincoln Navigator. I did purchase the 20v impact wrench from the same company but that one did not have the strength to take off any of my lug nuts. Also includes 12v plug in case you forget to charge the battery. If your looking for something that is able to help take of your wheels and not spend a lot of money this is a good deal.

TRIED TO USE IT FOR THE FIRST TIME, WOULD BARLEY BACK OFF A LUG NUT THAT WAS ALREADY LOOSENED. TOTAL WASTE OF MONEY.

“The 12V IMpact Wrench is designed for the fast removal and tightening of vehicle lug nuts when changing tyres. It is intended for occasional intermittent use and not commercial purposes.CAUTION the 12V Impact Wrench can only be used on small/midsize cars. It SHOULD NOT be used on trucks and heavy machinery..” [Their emphasis, actually caps and bold. So, not advisable on truck and trailer wheels. If you compare this lightweight tool to the battery-powered impact wrenches by DeWalt, Kobalt, and others, those are 20V or 24V. If you compare to corded impact wrenches by those names, you’ll find they weight around 8 pounds - much beefier.]“Do not apply excessive pressure to the 12V Impact Wrench. If the nuts cannot be moved and the wrench freezes, cease operation immediately and continue with a manual wrench.“ and “If the Impact Wrench cannot loosen the lug nut, use a breaker bar (not included) to break the nut loose before trying again.” [i.e., you’ll still need to pack your lug wrench - plus a breaker bar to increase leverage - so this tool does not eliminate the need to carry your lug wrench. The Impact Wrench can then be used to speed removal.]“Screws, nuts and bolts that have been tightened to a specific torque should be tightened with a torque wrench once the tyres have been fitted in place.” And “IMPORTANT It is highly recommended to use a Torque Wrench after use of the Impact Wrench to correctly and safely set the wheel nut.” [i.e., don’t trust the Impact Wrench’s digital readout, finish with a torque wrench . A new torque wrench runs $89 and up at the big box stores.]“Do not run the vehicles engine while using the 12V Impact Wrench as this can shorten the life of the appliance.” And “Check if your vehicle requires the ignition to be on to power the socket.” [So, before purchasing, check that your car’s 12V source will be available with the engine off - otherwise your only power source will be the included rechargeable battery, and in that case, you may decide to go with one of the heavier weight 20 or 24V impact wrenches.]

Feels like its built well and breaks lug nuts with ease

Excellent impact wrench, use as intended easily removes Mercedes Sprinter lug nuts and torque is accurate.Not as robust as the Dewalt's I have but excellent to keep in a truck or car connect to car battery for tire changes.

Tried a different impact wrench first and it couldn’t budge my lug nuts. I wish I would’ve picked this one first as it worked really well. I still have one lug but stuck but the dealership definitely waaay over tightened it but I was able to swap out 3 of 4 tires with the this guy.Only knock is the small battery. It lasted long enough for me to swap two tires (take off, put new ones on) before I had to plug in.
