This is a lifesaver. I used to have some piddly little jump starter, which would occasionally work, but often just fail.

This unit is different.

This just works. Always. It has a useful display, indicating volts and charge capacity, lets you jump a car many times before recharging, and will work for literally months between charges. I've jumped dozens of cars using this unit and never had a problem.

You're going to have to buy an extension cord to charge it from the wall. $2 at Home Depot. Two prongs, non-polarised.

If you have to buy a portable jump starter, whether to keep in your truck, the back of your car, or just your garage, think about whether you're willing to tolerate it failing right when you need it to work. Buy once, and buy right. You'll save money and grief if you just get the best up front.

I have used this product twice. Both times it performed flawlessly. I jump started a car with a only 4% power level and it started the car with no problem. Great product and I would recommend it to anyone

I received this item last week, plugged it in the AC for 36 hours per the "Warning Tag" attached to the handle (but contrary to the 8-hour recommended in the instruction pamphlet enclosed). I guess the reason they put it on a RED tag on the handle was probably due to the instructional pamphlet being in error, so that's what I saw first and complied with. I used it to start my 2004 Kia which had a battery completely run down to nothing, and it cranked it right over. I only used the car for a short trip to the store that day, however I had to use it again this morning again. Well, it had just sat in my back seat for the last few days, and I wondered if that single charge up would have been sufficient or whether I'd have to hook it back up to the AC again first. Nope! It cranked the car right over and it felt like there was plenty of reserve power left over to do it a few more times with no problem.

I'm very satisfied with this product, and would not hesitate recommending it without reservation to anyone who needs a life-saver for their car's battery. It sure beats calling a two company to jump-start me in the morning, or try to impose on a neighbor or stranger for assistance.

Bottom line, I don't just like it, I LOVE IT!! I also want to add that I am in no way affiliated with the manufacturer or seller, and this review comes unsolicited from a simple consumer like yourself.

MONEY WELL SPENT.

I left my car at my dad's for six months. The battery was a five year battery which was four years and eleven months old. When I went back the battery measured 0 volts. I had just received the Scvhumacher 3600, but had not unpacked it. I tried my 400 peak amp; 900 peak amp jump starter. No dice! I unpacked the Schumacher, plugged it in and let it charge overnight, although the digital readout showed 100% charge. Next morning, hooked it up, turned it on, let it sit for about five minutes. The car started immediately. I had to run on the alternator to the parts house for a new battery. I can't say enough good about this product.

Over the years I have had several 12V jump starters. None of them seem to last too long. I think it's a combination of the heat in my truck and not charging the unit properly. I asked around to many tow truck drivers and owners. They all recommended The Schumacher Pro Series Line of jump starters.

This thing is a monster. It ways a ton (battery) and the charging is simple. The fan runs when plugged in and it's not quiet. I have used the unit several times on completley dead batteries and no problems at all.

I found that it is top heavy so it won't stay upright so I lay it on it's side. It is a sealed AGM so that is no problem.

I also use it as a 12v power source for my emergency radios. I think it would last for many days of transmitting at 5 watts.

I hope the heat will not shorten it's life. We will see.

I now have had this for almost a year and have used it several times on diesel engines that have two large batteries. Turns over with no problem. This charger was the best idea.

It is not cheap but it's worth it for sure.

When you charge the unit, charge for 24 hours.
