This is a great purchase that you never hope to need. However, I was thankful to have it. It's a bit heavier than I expected but because I kept it charged as per the directions, when my battery went dead, I wasn't stranded. I was able to quickly charge my vehicle without asking anyone and was on the road in less than 10 minutes. Buy it!

Works good not as nice as my old one but better than my dewalt w stupid buzzer making noise

Great jumper box! Does exactly what it says it does

I love this thing! It was the best money I spent all year! Of course little things could be better like the hose for airing up your tires, it has a cord wrap on the unit but there's nothing to keep the hose there, needs like a small bungee or Velcro to hold it in place during storage. This thing has saved me hours and hours of waiting and frustration. Also to make it perfect, supply a small extension cord in the correct guage for recharging the unit, I just happened to get lucky I had one.

This review is for the SJ 1289. I've owned an older version of this Schumacher power jump starter/ power station. I've bought 2 of this current version too. I really liked the older version, I really LOVE this newer one. As a jump starter, it works great on my minivan and other vehicles. Works great as a tire inflator. Although I've not needed to pump up a completely empty tire using it, it is perfect for checking tires and adding some air or to top up a tire that has a slow leak. And it really shines as a power source, has a 120vac outlet and 12vdc outlet and USB outlet, so you can connect anything to it (up to 400 peak watt limit on the AC outlet). I've used it on camping trips, and road trips, and taken it to outdoor events. But also I've found it useful around the house and yard (bring power anywhere when needed). The unit is bulky and heavy, but that is not an issue for me, it's easy enough to carry. These are built well and will last a long time.

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.

Starts 5.3 liter GMC with no problem.Good compressor for pickup tires.Just recharge every month as per directions. I didn't and had to replace it after about 4 years. My bad.

I bought one of these from Walmart years ago, and it still works. I liked it and bought another from Amazon. This new one arrived unable to take a charge, and CANNOT BE RETURNED. Now I need to figure out how to return it because I am out $100, and it is a paperweight. It simply does not work. I've tried to charge it, as the instructions state. I know how these work because I've been using the same model for years. I will have to find a way to return the one that does not work. It really is too bad. The first one I purchased (from Walmart) was quite good. It's risky because if you get a lemon, returning it will be a bit of a pain.Update: Amazon is helping me with an exchange. If the new one works as well as the one I bought years ago, I will add more stars to the review. I was very happy with the older one.Update: Amazon replaced the item. The new one works as expected. I have taken it on a trip and it worked well. I am happy with the purchase.

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.

This product works great! But the truest test was when I forgot it was in the bed of my truck! Watched it falloff, hit the rv, then skid across the freeway while accelerating to 70 miles an hour! Thought it was destroyed! When I turned around to pick it up, it had just a little road rash but still works perfectly!! Schumacher definitely takes a licking but keeps on working! I just wish I had purchased the one with the higher boost rating! OUTSTANDING VALUE, OUTSTANDING PRODUCT!
