JNC325 Jump-N-Carry 2000A 12 Volt Jump Starter for up to 8.0L Gasoline and 6.0L Diesel Engines

I bought two of these — one for each car — and I’m beyond impressed. They replaced my older, bulky jump starters that used standard sealed batteries. The JNC325 is significantly lighter, occupies much less space, and still delivers substantial power. It easily started my SUV and has already helped me give a jump to a stranger in a grocery store parking lot.What I love:• Strong enough to start large engines (up to 8.0L gas / 6.0L diesel)• Compact and lightweight — easy to store under a seat or in a trunk• USB-C charging is fast and modern• Feels solid and dependable, with heavy-duty clampsBonus: Because it’s so compact, I don’t mind keeping it in the car all year — and it stays charged for months—great peace of mind, especially in cold weather.Whether it’s for your emergencies or to help someone else, this is one of the smartest things you can keep in your vehicle. Highly recommend.

I don’t drive much anymore, but when I do and the battery is dead, this jump starter starts my car up right away. I’ve jumped it four or five times on the same charge and it still has plenty of charge left in it. It is compact and easy to carry in a large purse or just in your car.

I really don't drive enough, and if my battery wasn't in the trunk under a spare tire etc, I'd rather just disconnect it until I did want to drive (2014 LS1 Camaro). So it stands to say my battery dies regularly - hence me buying this. Gave the instructions a quick once over and turns out all I needed to do was make sure it was already charged to 75-100% then get started. Pop the hood and attach the jump cables to the Jump-N-Carry, then red to red and black to black, wait for a green light and crank the car up 6 seconds later. I think it started faster and more clear than when I bought the car brand new in 2014.My car battery has never gone full dead, so I can't comment on the override button for full dead batteries, but it's mentioned in the instruction manual.Cons: Previous reviews never mentioned something simple like if charging this with a USB-C from the car works, instead talking about trying to charge it via the alternator? Why?TLDR: Easy to use with charge, connect, jump. Cables reach about 2 feet apart. I'd rather buy this once than pay for triple A, or wait for someone to answer the door or phone to jump me, so worth the price. I accidentally turned on the light while trying to turn it back off after checking it's power supply and nearly blinded myself so I think I'd call that bright.

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.

Worked like a charm. I have a parasitic draw on my battery that I have not figured out yet, so if it sits for a few days the battery is totally dead. I've jumped it with this device three times and in each case it started right up. The only issue I've seen is that my battery is so low that the device doesn't detect it properly, so I have to put it in override mode to get it to work. But once I did that - the car started right up every time.
