Best in class--had a couple cars with shorts that needed lots of jumps and went through three other brands. Every one under $100 could not last or keep a charge long enough to work on demand.
The 2212 instantly started a dead battery on cold mornings. The 3 amp charger is much faster than cheapo models.
Basically it is a durable solid unit. You'll need to spend over $200 for a better jump starter. The long cables let me solidly place it while jumping, unlike the other boxes that barely reached.
Buy it & you will love the security of genuinely professional grade peace of mind.

Ill give you the good news first. This item will spin my 4.3 liter high-compression V8 like there's no tomorrow, and it will do it at least 5 times on one charge. It will hold a fresh charge for three months. It has a huge red digital readout that serves several purposes. It will let you know when you have a good connection to a car battery before you switch it on. It will let you know how much voltage it is providing, and it will tell you the charge state of its internal battery when it is in charge mode. There is also a warning if you cross up your leads. There is a cigarette lighter socket for 12V access.
Now for the bad news. First, you have to provide an extension cord, and, when you do, there's no place to store one of any length on the device. My advice is to buy the shortest single-socket 16AWG cord you can, and squeeze it onto one of the side hooks where the leads are stored. Otherwise expect to just leave the cord behind (probably the manufacturer's intent) or carry it separately. Second, while you can leave the charger plugged in full time without overcharging, there is a noisy fan that runs full time (and draws about 6 watts along with the display). Even if you charge it in your garage, you probably won't want to just plug it in and forget it for two years, because that fan will wear out sooner or later. At least it sounds like it will. (I wish they'd used a quieter fan of the type that comes on desktop computers.) Don't plan to store it in an unheated area in winter, because performance will suffer severely, although a sealed garage is probably warm enough in most climates. Finally, you can't use this thing as a charger to maintain a car's battery in the garage. It's not designed for that and won't allow it.
I'd like to make a couple of final points about battery-powered, jump-start devices in general. If your car's battery has failed catastrophically, meaning it's almost like a short circuit, you must disconnect one lead of the battery before using one of these. (Assuming your alternator is good, you can reconnect the battery once the car is running.) Otherwise, the bad battery will suck the charge out of the jump-starter. You may have encountered such situations with jumper cables, when you find you have to partially recharge the dead battery with a running car's alternator before you can start the car. This is the kind of thing that happens when you leave the lights on for a long time. It should not be the kind of thing that happens when you have tried to start the car and heard a clicking noise.
If your car's battery is dead because you've run it down while trying to start the car, you'll probably run the jump-starter down too. In fact, it will probably run down faster than your car's battery did, just because it's not as big. Don't blame the jump starter for either of these situations.
This jump-started does what it's supposed to do, and it is a good price. If you can live with the cord and the fan, and you don't ask it to perform miracles, you'll be happy with your purchase.

If you buy this product, watch out for one very strange quirk: No matter how fully charged the battery is, the digital readout will ALWAYS say it is 10% charged when you plug it into a charger. The readout will slowly creep up towards 100% over a few hours. But this readout is false: It has no connection to the actual charge on the battery. To determine the actual charge on the battery, press the "%" button on the unit and it will tell you the actual percentage the item is charged.
The Schumacher customer service department doesn't know that this is how the product works, and they will tell you that the unit is broken if you ask about it. You'll then have to pay $35 to ship the unit back to them to get a new one (it's very heavy), and it will take several weeks, and the new one will seem broken, too. But it's not: It's just a strange quirk of the way these machines are designed. Trust me: This happened to me twice before I figured it out on my own.
UPDATE: I have changed my rating of this item from three stars to one star because after having the unit replaced twice for the reason above, the third unit I received just totally stopped working within about two months of it being sent to me. This time, the unit was really dead: It takes no charge no matter how long it is plugged in, and gives zero read out. Ironically, I couldn't get a replacement unit because the new replacement was no longer under warrantee: The clock on the one-year warrantee started ticking when I received the first unit, and it was just about elapsed when I received the third one. So I ended up spending a year dealing with the service department to "fix" units that weren't broken, and then at the end I received a unit that stopped working after about 2 months. I guess it just wan't meant to be. I hope others are luckier with this product than I was!

I am on my fourth jumpstarer and after all the previous junk this is a keeper. At 22 ah it delivers enough cranking power for must vehicles, in a nutshell it is a self contained unit with trickle charger and voltmeter, the fan that cools the charger is a little bit loud and never shuts down even after full charge is reached don't know why. Finally I own a REAL jumpstarter.

This box sells for $300+ on the tool trucks, and is a professional class jump starter. You can crank a turbo diesel that has two batteries with this bad boy and not even make it sweat. Im giving it 5 stars even though you will have to buy an extension cord to charge it(because the jumper does not come with one). Any one in the automotive industry needs one of these in their shop.
