Helped a trucker get his dead rig fired up outside of colorado springs a couple weeks ago in single digit temps. I'd say this battery does what it should!

This is the third one I have used and liked it enough to buy one for the business. I have jumped three different vehicles on one charge and went to charge it and it still said full. I jumped a 15 passenger van form dead with no problems. The cords are nice and long and I like the ease of use. I would buy one for me personally, but I can use this one whenever I need it.

Can't believe I've managed without one of these. Been through all kinds of jump boxes. Small ones, big ones, they all seem to take a crap after awhile. This one is solid. I've had it for awhile and just now charged it and honestly probably didn't need to. This thing is a beast. Quality is too notch. I'll never buy anything else. Probably won't need to anyway.

Bought it, and it sits plugged in, continually charging in my garage, waiting for the day I need it.

Hany piece of equipment to have around the house. In this weather one never knows when a jump is needed.

This thing is very heavy and clunky, but I don't mind keeping it in the trunk because it is RELIABLE when you need it.I've had to use this thing a handful of times, and each time it's quick, easy to use, and reliable.1. Connect the red, connect the black, turn it on.2. Start the car3. Turn it off, disconnect black, disconnect redDone.Couldn't be easier, and I never have to worry about a dead battery again. I highly recommend this.

My mechanic loaned me one of these to allow me to get my car in for a new battery without having to tow it. I immediately bought one for myself! Brilliant device!

I've had a jnc660 for years and it worked great. I got sick of no one charging the shop one. So I bought 770. Great starting power and love the long cables. Came with the power port cable which makes a great memory saver when changing batteries. I don't have much use for the light or usb but would be nice as part of a road side kit.

Soo awhile back I broke down 2 hrs from home in my truck, alternator went out, long story short tow truck arrived and had one of these bad boys, he said to me if I had one of these I could have hooked it up and drove my a home , and not long after I bought one, and living in northern Minnesota it gets well below 0 during our winters this thing has saved me and allowed me to help others! If your thinking about buying it! Quit thinking and buy it!!!!! Better t have it then not have it when your stranded in the cold!

Bought as my vehicle has an intermittent parasitic drain on the battery. Have use it four or five times to start that vehicle, without recharging it. It was used to start a 3.4l engine that the battery was dead. It started that engine immediately.First recharge on it today, after initial charging. Bought the 770 over the 660 as I have a couple pieces of equipment that in the cold sometimes need a little help.All in all, we'll worth the money.
