Worked once when it was new. Charged every couple of months consitently, but can't start a car, and the DC power adapter doesn't work either, with full charge.

Have used once on a weak battery where car sat too long. Worked as expected, hence 5 stars. Haven't had chance to use on a completely dead battery where one needs to push the override button, so can't comment if works in that situation.

Startes everything with no issues. I love the larger clamps...many of these have very small clamps for the battery posts...these are a little larger so easier to put on.,

Just used my 2000A version for the first time and worked perfectly. Large Volvo SUV, battery completely dead since I left something plugged into the rear power port like an idiot. The jumpstart battery had been 0°F Minnesota cold car overnight, but I hooked it up, hit the power button, 4 bars of full charge. Hit the other button to get a green light, car turned over and almost started. Tried a second time and it roared to life. Used about half the capacity, but was moving in 5 minutes. What a fantastic resource. Get the larger size!I don't know if 24" cables are what I would call "long", but the clips are easy to use, I never read a manual or thought about it, just hooked it up and it started.

I live in a climate that is extremely cold in winter. This item is very worth the price for the piece of mind it affords. Just knowing it is there just in case I need it makes life all the better. While I have not had the need to use it on my vehicle, I HAVE used to jump start a friend who has the same engine as me (Vortec V8). I have also used it to jump start strangers in various vehicles and engines. The extra boost is AWESOME and immensely helpful. Great product. great value. Great piece of mind. MUST BUY.

What if you are stranded with a dead battery, and there is not another car in sight? Or there is another car, but no jumper cables!Wouldn't it be a life saver to have a 12v power pack designed to jump start an automobile. With its own jumper cables!That's exactly what the HPBS Jump Starter is, and more.This 12v jump starter power pack comes with jumper cables, a USB charging cable (but no power adapter), a cigarette lighter adapter (though many autos no longer come with a cigarette lighter) and a user's manual. All in a really nice, and sturdy, storage case that is only 9.5"L X 5.5" W X 4" H.The power pack also comes with two USB outputs for powering other devices. And also includes a built-in LED light with three functions (flashlight, SOS, strobe).The cigarette lighter cable enables "reverse charging" that provides charging of the car battery, in roughly 20 minutes, through the cigarette lighter port.The one disturbing issue for me revolves around temperature. In the Care and Maintanence section of the User's Manual there are two warnings:"DO NOT put the product under direct sunlight or hot areas."and,"DO NOT place the product in high temperature environment for long. The operating temperature: -22F - 140F."These are direct quotes, including the all caps emphasis. Well I live in Texas, and I am concerned about what I consider to be somewhat vague direction. In Texas, in the summer, even a garage is a hot area. And how long is too long. I do not want to risk my car, or my home when the car is in the garage. Do I need to bring the pack inside the house when I'm not driving the car. But what about when I drive somewhere with the pack in the car, but when I arrive at my destination (lets say a dinner party, or a movie, or maybe a football game) do I need to carry the power pack with me to be safe? And in something like a football game or fishing trip where I would be staying outside what is safe way to handle this power pack?Also, the power pack requires recharging every 3 to 6 months.
