Product Description
Amazon.com Product Description
The versatile Schumacher PS-400-3A has a maintenance free, 18 ampere hour battery that delivers 850 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 PS-400-3A 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 PS-400-3A 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.
The jump starter on/off switch shuts off the internal battery at the clamps for added safety, eliminating accidental shorting of the clamps. A 12-volt power outlet allows you to operate any number of 12-volt devices. Its extra wide base provides maximum stability and safety.
Safety and Convenience Features
The PS-400-3A is loaded with safety and convenience features, including a reverse hookup protection to safeguard the car battery, computer, and Instant Power from damage in case the cables are connected to the wrong terminals. An audible alarm warning sounds when clamps are reversed or touched together.
 The PS-400-3A gives you portable power to jumpstart nearly any battery. |
Easy to Use
To revive a dead battery, simply connect the PS-400-3As two cables to the battery terminals of the stranded car and turn the key. After providing a jump (or every few months, if stored), the unit should be recharged by plugging it into a wall outlet with the included cord. The sealed lead-acid battery provides enough power to operate a cellular phone for 30-plus hours, a depth finder for 21 hours, or a camcorder for 12 hours.
Features
The display is comprised of easy-to-read battery status LEDs, which tells you when internal battery is at full power, 75 percent charged, or at 50 percent or less. A simple push of the button instantly turns on the display. The heavy duty, copper jaw, 300 amp, metal clamps are designed for solid connections to top and side post batteries. The #4 gauge, 28-inch cable stays flexible in the coldest temperatures. The LED indicator lets you know whether the unit is in charging or charged mode to help easily monitor the status of the internal battery.
Durable and Easy to Store
The PS-400-3A is rust and corrosion proof, featuring a one-piece construction and a polypropylene case which resists fuels and solvents. Storage mounts on the back of unit keep the clamps in place for safety when not in use.
Warranty
Every Schumacher power source comes with a one-year limited warranty (90 days on battery).

Not the whole story,
By W.C. "Diver" (Alexandria, VA) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: Schumacher PS-400-3A Instant Power Jump Starter (Misc.)
The jump starter arrived very quickly and in good condition. I got this system for my wife after she spent 90 min trying to get someone to jump start her car recently. However, there are two issues folks need to know about before they buy this unit. First, You will need an extension cord (with only one female connector) to charge this unit. It does not come with a plug as part of the unit and the male prongs are inset in the unit preventing you from using a strip extension cord. Second, I would recommend also getting the 12V DC male-to-male connector. This will allow you to charge the unit in the car, while it is running of course, and it will allow you to jump start the car using the 12V plug. You can either make your own or I found one from Schumacher (SAC-109 part number). By the way, it does come with a plug-in light that can fit into the 12V adapter.

This review is from: Schumacher PS-400-3A Instant Power Jump Starter (Misc.)
This product was exactly what I expected. It was lightweight, durable, and compact. The included lamp is handy, but I mostly bought this to use car accessories when I didn't have a car handy. The 12V outlet is great for exactly that. Charging can be a bit slow (up to a full day from dead) but the unit is a great piece of equipment. The only this that's annoying is that it doesn't come with a car charger - you have to buy the cigarette-lighter adapter seporately. I just built one for about $4, so it isn't the end of the world. Just cut the ends off of two cheap car chargers (non-voltage changing ones) and wire them together. Plug one end into the car and the other into the unit.

Good charger; worth the extra $$ over the cheapies,

This review is from: Schumacher PS-400-3A Instant Power Jump Starter (Misc.)
I've learned from my mistakes. I've purchased two of the cheaper jump starters (one Coleman, one Vector, probably made by the same folks) and both stank. They don't give enough power to do than more than a couple of cranks in warm weather, and are worse in the cold. Worst of all, the cheap plastic clamps broke. It was difficult to open them wide enough.
This charger, on the other hand, works very well, and it's a great value. Lots more power, charges up efficiently, and has solid all metal clamps. You do need an extension cord with a small enough female end to charge it, but that's easily found. BTW, aside from the obvious uses of this product, it's nice to have the male-to-male cigarette lighter extension cord. This allows you to provide power to your vehicle when you are swapping out that dead battery that was giving your problems, which means that all the electronic settings in your vehicle are preserved during the swap.
