12V corded impact wrench

Does anyone have experience with this type of wrench? I'm considering one that produces 300 lbs of torque. Powered from cigarette lighter or alligator clamps to the battery. It is fused at 15A. Is it possible that it will work reliably?

Oh and while you hinge your bets on that one poster... lets ignore the others.

The cordless torque wrenches are pretty strong these days, especially when paired with a breaker bar. I'd recommend that.
For me, I don't think that 50 dollar impact is going to be better than a breaker bar and a ratchet tbh. Look at the 1 star reviews. Some are saying 1 impact per second, which I think will be a common problem with these 12v chinesiam impacts.
I agree with MJB
a good cross tire wrench will always get the job done
I have no experience with 12 plug in tools other than air compressors, and they historically suck
I am betting 32 lug nuts at over 100 ft lbs would be an issue
Skip the $45 Chinese crap tools for emergency use.
i have an old corded impact, but for the room it takes up (and its not going to run off the cig lighter, which means a large inverter), it stays at home.
Keep in mind, most of those favorable reviews are for passenger cars with low torque specifications.
Busting loose a SD lug nut is going totake some power.
had a 12v inflator like that before, wouldnt touch our 80lb tires
i always keep the M18 mid torque wrench and M18 inflator with me. dont forget the 21mm

I’m not sure of the tool you’re looking at so I can’t say one way or the other but as an option, I bought an M18 FUEL™ 1/2" High Torque Impact Wrench with Friction Ring and it will produce up to 700 ft-lbs of maximum fastening torque, 1,100 ft-lbs of nut-busting torque. The M18 is a cordless monster and will remove damn near anything. Not inexpensive by any means but I had most of the fuel tools to begin with so it made sense for me to buy this unit.

Thanks for replying! I don't want another battery to maintain but I want a power impact wrench to keep in my truck in all kinds of temperatures. Also, a cordless tool would require me to have a spare battery. It's for emergency use (rarely used) and to make things easier on my ailing shoulders. One review has used this one on 125 ft lb nuts OK. I believe I'm at 165 ft lbs. I already have a 120V heavy duty impact wrench, and a huge battery booster, but I don't have an inverter big enough. The cost of an inverter would be 2 or 3 times the price of the corded 12V wrench. The one I was considering is

If it's going to be used for emergency use, it's up to you to decide how much that's worth. For some guys, the 1/2 gun from Milwaukee is worth it's weight in gold (it is). For others, it's not worth that much for something that will see use maybe once or twice.

For me, I don't think that 50 dollar impact is going to be better than a breaker bar and a ratchet tbh. Look at the 1 star reviews. Some are saying 1 impact per second, which I think will be a common problem with these 12v chinesiam impacts.

Let me let you in on a little secret... this isnt enough wire for any grown individual to rely on this tool

Shop for quality tools, or hire someone.

The wire and connectors are certainly capable of carrying 15 amps, which is the maximum needed for the wrench. A fuse will blow after that point, so your response makes no sense. It's snarky too. The question is whether the tool will do the job or not, based on general experience.

I have one of those emergency kits with the cig lighter powered impact -- works pretty good the times I have used it
Kit has the "impact" gun and sockets in a carry case -- pretty handy on trips for storage
if I took everything that I thought I would, it would require a trailer to haul it all

Anyways, the impact winds up to speed and hits once - then you have to release the trigger and do it all over again
this is slow, but it will loosen a lug nut -- usually only has to hit a few times, then a lug wrench will finish the job
you are broke down on the side of the road, ...what else do you have todo ?

Get the M18 Milwaukee. It will hold a charge for months.
I use mine for all kinds of work on the truck. Air impacts are stored away somewhere now.
I have a bed cover and Put mine in a milk crate in the bed. Transfer it to any other car if I’m going on a long trip.
Expensive but worth every penny.

I understand that. I don't like junk and I am not opposed to spending money, but I don't want another cordless tool. I would sooner just keep using the stock tire tools and try to baby my failing joints. I also refer to some things as crap, but not without knowledge. I'm still hoping for another member here, like Hydro, who has experience using this particular type of tool.

Oh this is fun...

I understand that. I don't like junk and I am not opposed to spending money
So lets shop for cheap china crap on Amazon and argue with people who tell you its junk in hopes that someone will agree.

Other helpful comments include

My posts clearly stated what information I wanted, as well as what I don't want.
and

There are lots of very favorable reviews about the tool I looked at. And the one poster here with a similar tool had good results. .
ONE POSTER... haha clinging on to those failing joints like you are hope for this junk of a tool.

Luckily for you we respect @Hydro.

@Stt I appreciate your commitment to doing things the hard way.

@Hydro what were you taking the lugs off of and link us to your tool since you are the savior in the convo
Another snarky remark, or real sarcasm. Just keep it to yourself. My posts clearly stated what information I wanted, as well as what I don't want. There are lots of very favorable reviews about the tool I looked at. And the one poster here with a similar tool had good results. I don't know what your goal here is but it will be best if you just move on. It's my thread, not an Admin thread.

I like how you think attacking me will net you any good result.

Since you are showing signs of being senile I'll help you out.

Does anyone have experience with this type of wrench?
Yes, I do.

As I stated those wires are to small, that 15A is the MAX for that circuit which is why the fuse is 15A. Also the cig lighter is also shared with the Dash cluster among other things.

So now that Hydro has your hopes up, lets see a video of this impact taking off a lug from a diesel truck after your tired shoulders jack it up using a cheap bottle jack.

I'll wait.

So HD, you have added no substance to this thread. I'll watch a little more for informed opinions about this tool.

No sir, you may not share logic in this thread... lugs are lugs.

That is the same way the one I have operates -- one hammer at a time

Just get the torque multiplier tool and be done with it
one like I linked earlier would be good for each vehicle

The larger multiplier that I use on the Budd wheels will snap a wheel stud off pretty easily -- forgot about the LH threads on the driver side
this thing has 1 inch drive -- 450 on the inner and 600 on the outer nuts

I kind of like this thing. But beware the similarities to my original post. Cheap, Chinese, video that shows it working, a few bad reviews. Oh no! The guys will blast you for sure.

All good, ...just posting that as an alternative for emergency work

To update, here's what I ended up with; I bought a power inverter (12V DC to 120V AC). My decision was based largely on what I already had, which was a lithium jump starter and a heavy duty corded impact wrench. I have all the sockets and extensions I need. A bonus is that I can use the inverter in my on-going solar power experiments. I may never need to change a dually wheel on the road but I can. I was surprised to find that I can't remove the dually hubcap with anything Ford supplied, so I made a simple puller. I've had a blowout on my camper, and a flat on my truck - one in a dangerous spot and one in a remote spot.
