Thumper Dual Max Compressor

Who knows Jeff, some specs on such things are a little over stated I'm sure, air comps and solar panels are 2 such things.
150psi / 150lt / min is good for mos 4WD tyres, and most twins are this spec, so you should be right with this one.

4WDSC ?
Just try and go into a shopfront, see the product, and buy it instore.
Online can be a crapshoot and after sales (after they've got your $$$) service is sadly lacking with this company.

If it is anything like their previous model which was 150lt, I don't think you can complain. Have had for over a year now and used many times and it has been faultless, and these were only $95 delivered.
At the recent Adelaide 4wd show there were many rebadged versions the same as 4wdsc ones, just different colours and they all had the same specs. They were asking up to $299 for the same unit.
I personally wouldn't have any hesitation buying one.

I've had one the twins for about 6 months and used it quite often in that time.
For the price I can't fault it, its' extremely quick and has a constant flow of air. But as with anything motorized they will fail eventually so when on a trip in the bush I always carry a manual foot pump as a back up.

I've got the single cylinder version and it works good now. I bought it in store, took it on its first trip and it wouldn't turn on. I tried to take it back to the store and they wouldn't take it back. They said I had to go through head office which is total crap. Dealing with head office was an exercise in exasperation that got nowhere, the girl on the phone sounded like she had been inundated with complaints and couldn't give a rats. I almost just threw it out but decided to take it apart and found a wire solder join that had broken. I rejoined it and it was off and running.
Would I buy from them again.....not likely. The gear is well priced Chinese stuff with hit and miss quality control. If you get a good one you will be happy with it. If you get a bad one you can be philosophical about it not costing a fortune.

They pull up to 90Amps!!!
I've used the single cylinder ones (up to 45Amp) for a few years now, and feel no need for anything quicker.

They are pretty big, heavy and pull a heap of amps.
Do you really need to take 60 seconds of your 150Lpm compressor time?

I know a couple of people who have these and they are happy with them.
Sold under a variety of names at considerably more cost.

4WDSC usually sell them for around $109 so watch their deals page.

I have had the Single one for a couple of years now , it pulls 45amps , I was surprised how hot the power lead got , I shortened the lead as much as I could .
I have used it a fair bit all ok .

A mate bought the Twin model just yesterday

Yes I noticed the 90 amps current. Want to have your engine running big time.

I know the modern 12v compressors are quite good but do they really deliver 300lpm at 150 psi ?
My V twin shed compressor is 8cuft/min at 110psi or 228 lpmin and requires a 2hp motor to drive it.
12v x 90 amps for the twin is around 1000watts where the 240v ac is pushing 1500w or close to that and is producing less volume and psi.

Just wondering if the stated performances are true, the physics indicates it isn't possible.

I bought my son one for Christmas. It burnt out on the 6th tyre on a very hot day. Took it back to the Brisbane store and they replaced it no problem. Second one is going fine so far. Very fast and did 8 tyres in a row coming home from a recent Fraser trip.

Thanks for the responses. I'll give one a go and see how it lasts the distance.
Probably buy the 150lpm for myself and the son gets the 300lpm.

Cheers
