  • This jump pack is a beast !
Style: 12/24V 4400 Peak Amp Pattern Name: Jump Starter
I have had a j7mp pack around the shop for years, but charger went bad and couldn’t find a replacement. After some research, I decided that I wanted a Schumacher . This unit came in and is pretty heavy, but starts anything that I have needed to get started. I don’t have any 24v equipment, but this jump pack has the ability. ... show more

Style: 12/24V 4400 Peak Amp Pattern Name: Jump Starter
really works starting HD equipment. Heavy though, to much for little lady or old person. I have had several of these, do NOT use when jumper can get wet, don't leave in uncovered pickup bed when washing your truck or raining as unit isn't waterproof and water will corrode switches. Use a double headed cigarette plug to keep charged ACCORDING TO INSTRUCTIONS Or plug into 110 volts. I have used the 24V feature carefully and sparely to start tough 12V equipment but only as equipment is turning over as this can burn out solenoids and other electronics as I have. Buy from Zoro or Amazon, can be used in conjuction with jumpers. ... show more

  • NOT WHAT I EXPECTED
Style: 12/24V 4400 Peak Amp Pattern Name: Jump Starter
This is not as good of a portable jump starter for the average person, and or, household. It is extremely heavy and requires a cart to move it around. The price of the jump starter is way too much for its poor quality and design. I had expected a jump starter that could crank/start every vehicle that I had in my home and that the average person would have in her/his home. But, instead, I bought a heavy piece of junk!! The jumper cables are way too short and so too are the clamps. One would think that because it is so heavy, and made for heavy and larger vehicles, that the cables would be long enough to reach a none lifted pickup truck while the jumper is resting on the ground. Another issue with this jumper is that it is not very user friendly. When you turn it on the jumper has a problem trying to determine what type of battery it is connected to. It keeps defaulting to AGM battery mode for all batteries. Then, when you try to override the default setting, it turns off. I had to leave it in the AGM mode for a minute or two, then, manually switch it to standard mode for none AGM batteries. Also the switch that turns it on is quite flimsy for a heavy duty product. Plus, the jumper doesn’t seem to have the juice to crank up my F350 Super Duty pickup truck. This is by far, the worst jump starter I’ve ever purchased and operated. It is totally overpriced and overrated. I’ll be returning it tomorrow!! ... show more

  • Does it's job and does well.
Style: 12/24V 4400 Peak Amp Pattern Name: Jump Starter
I like the long cables. It make it easy to jump vehicle and equipment with remote post, or if you want ground to the chassis like your supposed (who really does that), or you don't want to set the jump in the engine bay or un stable surface. The clamps are strong and grip well not too bulky. It seems you can get a lot of use out of the battery but I have not use it enough at once before it says it's low. When my big deep cycle winch battery dies on my car hualer I used and it preformed flawlessly. It is a bit heavy but I guess that how you get the most power density you can. ... show more
