Schumacher SJ1330 1000 Peak Amp Jump Starter and Air Compressor with 12V USB Portable Power Ports

I purchased this unit as a replacement for an older one whose battery was failing, which is to be expected after a number of years. This new unit has a strong battery, which easily started a vehicle with a V6 engine in cold temperatures (30's). It is more powerful and smaller than my old unit, and does not weigh more, and perhaps weighs a bit less. The auxiliary power ports ( USB, 12V) I found useful in the past, so having these was important to me. I much prefer using this for jump starting because it has a power switch for the battery cables and a reverse polarity indicator, which are good safety features, especially as compared to jump starting from another car. The power switch prevents sparking when connecting the cables to the battery, which can cause an explosion in some circumstances. My only initial disappointment was the short battery cable, which required that the unit be placed near the battery (the old one could be placed on the ground). It needs to be placed within a foot or so of the car battery. I do not see that this will create any problems on my current vehicles.

Wonderful product has helped immensely numerous times. Have used for jumping of car batteries, and for refill of car tires.

I only used this once as an air compressor to fill the tires on my wheelchair, and although it worked fine to inflate them, when I went to unscrew the fitting from the valve stem a lot of the air escaped before I could get it off. Then I tried to fill them a second time, and when I sit the little piece inside broke and it wouldn’t depress the schrader valve inside the stem, because part of it broke off, so it wouldn’t inflate the tire. I contacted the manufacturer and they told me that I could send it in to get a replacement, but I would have to pay the shipping, or they gave me the part number so I could just order the part myself from someone else. Since that was cheaper i opted to buy a different style of tire chuck on amazon instead that wouldn’t allow the air to escape upon disconnection.

Fast shipping small size - starts my V8 cars and trucks no issues, cables are a little short I prefer they were longer but it gets the job done, good unit, good price no complaints after 6 months

I bought this back in November. Have only used it a few times and the compressor stopped working. I mean it's still moving but it's like the gear or something must have stripped out. It's a piece of junk I wouldn't buy it. I paid $75 for this thing and I can't even pump up bicycle tires with it piece of junk

Capable and gets the job done. The peace of mind, once thought to be provided by carrying a set of jumper cables, has been taken to a whole new level! Manageable size and weight. Takes up very little room in the trunk. Everyone should carry one in their vehicle.

I load tested and all I could get was 200 amps. Open it up and the jumper cables are connected directly to the battery. There is no mechanism in here that converts it to 1000a. Then again I have never once believed any brand converting 5 amps to 2500 amps (my noco 2500a - died prematurely) or this, 12v 9ah to 1000a. Anyhow, knowing these batteries will die within two years. I opened it up and swapped it out to a lithium battery. If it can last me 5 years I’ll swap it again 😂. Fits perfectly (got lucky) so long as you don’t reinstall the spacer. I extended the short red wires for the + and that was all it took. I also wanted to remove the pump but I left it all in there. Looks robust. Pay attention to the battery brand and ah if you want to do this too. Cheers

Air pump is not the fastest. 2nd one of these I've owned in 20 yrs

Tres bien en cas d'urgence mais pour gonfler un pneu de voiture c'est tres long donc pour dépanner en route exellent mais pour gonfler les pneus un peux faible vide la batterie rapidement

A life saver! Except the compressor for putting air in your tires doesn’t work properly...

Purchased this to start a dirt bike and seems to work well. Nice compact size.

Semble bien fonctionné. Petit format , agréable à transporter , peu encombrant. Les seuls problèmes sont : 1- Fabricant trop cheap pour fournir le cable d'alimentation. 2- À l'arrivé , un des supports pour enrouler le tuyau d'air était cassé.J'ai dû le coller.

Great little booster pack. Great for the job site with the air compressor. Runs fuel pumps on its own on auxiliary tanks and boosts anything running 12v.
