The versatile Schumacher IP-1850FL has a maintenance free, 18 ampere hour battery that delivers 950 peak amps and 250 crank assist amps. It provides extra power that 12 amp units just can't provide, making it perfect for truck and heavy duty applications. With the IP-1850FL you can make sure you're never stranded with a dead battery again. Forget about flagging down a stranger for help or fumbling with unruly jumper cables, the IP-1850FL is a rugged jumpstarter that will charge your battery and get you back on the road. And if you can't stay away from your work while you're out of the office, you can even count on the Schumacher to provide standard 12-volt power -- plug in your laptop or other devices just like you would at home. Includes a detachable 12 volt flex light to provide light in dark operating areas.

I bought this Jump starter in Dec. 2007 and to this day is working like a charm! What you must understand about this jumper is that it may or may not assist to start a bad battery (a battery that will no longer take a charge and you must replace). I say may or may not because it depends on the size of what you are jumping. Unfortunately all my cars are eight cylinder vehicles, so I am not that lucky. Until this winter, this jumper has NEVER failed to jump start my vehicles. This winter (2011), I did not drive my vehicle for over a month, with the temps in the low 20s, I tried to jump start my car only to have it fail. Well, this was a first so I took the battery out and brought it in to have it slow charged over night. In the morning, I discovered that the battery would not take a charge and was defective. So for those of you who think that this will jump start all cars, all the time - NO - but it will do what it was intended to do as long as the battery is not defective. I still feel that the Shummacher IP-1850 is a handy tool to have around. I highly recommend it.

It wasn't powerful enough to jump-start my car. I'd been on vacation, hadn't driven the car in a few weeks, came back to find the battery too low to start; the Schumacher did not do the trick. It's hard to say whether this was a fair test. I eventually used, not a jump-starter, but a recharger on the battery, which since then has worked fine. So we'll see how the jump-starter works if there's a next time, but it did not work in the emergency that I had.

Read the description carefully. I didn't realize it won't start a dead battery only a low battery. Tricky!

Unreliable, fragile parts and poor battery life.

I have owned this model for several years. I had to replace the internal battery after a year or so because it was leaking internally. After that the charging brick cracked and the spades that stick out of the back of the unit wobbled. I replaced the brick, I bought it direct from Schumacher. After another year or so the internal battery once again stopped taking a charge but a 3rd replacement didn't fix its charging issue. It seems that the internals are junked. Also the replacement power brick is once again cracked and the spades are getting loose. This isn't built to last and it isn't reliable enough even under moderate use. I am giving up on it and moving onto a Clore JNC660.

YOu can buy chargers for $35. Don't do it; you are wasting $35. Spend the extra money and buy this one. It's well worth the extra money. It will jump start the Star Ship Enterprise and still be able to handle your car in adverse cold conditions. It has an auxillary light so you can see what you are doing in the dark (you don't want to hook up a negative to a positive, because you couldn't see what you were doing). It doubles as a car charger if you forgot your cell phone wall charger and have only a car chager it plugs into this device. It is a bit heavy for some people. BUT IT'S RELIABLE. Buy and extension cord so you can plug it into the wall (it doesn't use one of those transformer thingys that you always seem to lose--it's a direct hookup. It's good.

I thought that the name brand would mean something with this product,but that was not the case. This unit lasted one year,before the internal battery wouldn't take a charge.

I put this on charge immediately after I got it and left it there, as recommended. Last night, we got a winter storm and the power blinked several times. I got it and my power inverter at the ready, so I would be able to monitor the weather situation via laptop and Mifi.

The power never did go out, but it made me think that I should test this baby out before I really need it.

I got this primarily for camping and emergencies, for use with a separate 12-120 volt power inverter. Having the jumpstart feature only adds to the usefulness of the unit.

Lead acid batteries work best when kept fully charged...that's why the alternator in your car runs all the time. Plus, it ensures that the charger is always ready to go when you need it.

I hooked up the inverter and my laptop's power supply over an hour and a half ago, and the Schumacher is still ticking away without issues. Indicator shows half charge, but it went immediately to half charge after I plugged it in and started using power. We'll see how quickly the power drains, but so far it seems OK.

I also ponder whether or not it would be practical to plug my power inverter into the rear socket in my SUV, charge the device and leave the it there all the time on charge, so that it charged a little every time I drove the car. If that would work, the jump starter would always be with you, would always be charged, and would always be ready to use at a moment's notice.

***UPDATE***

Using a 400 watt inverter plugged into my car's cigarette lighter, I kept the Schumacher plugged in all winter in the back of my SUV. It charged every time I ran the truck. By the end of the winter, the power supply was still showing full charge.

I did not buy this on Amazon, so this review is no reflection on Amazon or any seller on Amazon. It is only a review of this product. This has never worked to jump start anything. When it was brand new and still taking a charge, it wouldn't jump start my car or my neighbors car. Now I can plug it in for a whole day and it won't charge up. Since it won't ever get a full charge, it is useless. Actually, it was useless from day one. Buy something else!
