NOCO says this 1,000A jump starter will give you 20 attempts, but they won’t be all at once, and that’s under ideal circumstances. Like every other lithium jump starter we’ve tested, it has reverse polarity detection, alerting you if you connect the clamps to the wrong battery terminals.
Other units require assorted long and confusing sequences of presses, which might protect against turning on accidentally, but is a hassle when you actually need to use it. It turns on with a single short press to the power button, as does the flashlight, which cycles through multiple on and emergency flashing cycles. There are other little details that make the NOCO easier to use than other jump starters. They also use the same universal connector common across other NOCO products, so you could mix and match if you needed to, although you’d drop the amps with longer cables. The clamps, in particular, are great, even better than the GooLoo’s-weak clamps that don’t open wide enough can make it impossible to clamp onto a hard-to-reach battery terminal. It’s priced about the same as competing models, but is smaller and better built than any other jump starter of the size that we tested.

They also have long cables with heavy-duty clamps.įor more information on the best portable car jump starters, refer to our Table of Contents.Īfter using about a dozen jump starters in the AutoGuide Garage, we think the NOCO Boost Plus GB40 is the best jump starter for most people. Lead-acid jumper packs can be used repeatedly and are capable of cranking for much longer. Most lithium-ion jump starters can only be used above about 15☏, and are only good for three attempts before they need to cool down. High-wattage lithium-ion boosters are very expensive, so you might want to look at the conventional old-style battery jumper packs on our list. If you have a V-8 or diesel engine, have to start heavy equipment (or a lot of old cars), or live in an area with very cold weather, you’re going to need a much larger jump starter than our top recommendations. They also have reverse polarity protection, and won’t do anything bad if you connect them the wrong way around. Most of them have overheat protection, so after a few tries you’ll have to wait for them to cool down, but they also have enough power for multiple starts. You just clamp them directly onto your battery terminals, turn it on, and after a few seconds, try to start your car.
Portable jump starters are much safer and easier to use than jumper cables, although most of them can’t provide as much power. Almost all of them have USB ports as well, and we often use one in the AutoGuide Garage as an oversized battery bank to charge phones, so they’re useful in all sorts of emergencies. And of course, almost everyone has left a dome light or the headlights on, or an accessory plugged into an always-on 12V power port.įortunately, you can now buy one of the best portable car jump starters, charge it up, and forget about it for six months or more (they do need topping up occasionally, especially if they get very cold or very hot repeatedly).
Even in new cars and trucks, charging systems can fail, or a battery drain can slowly siphon power away while sitting. Even if you do everything right, they don’t last forever: You should expect to have to replace one every five to seven years, depending on where you live and how you use your car. There are a lot of reasons to end up with a dead battery. If you had a dead or weak battery and you were on your own, you had to get to a phone or flag down another motorist to have a chance of getting going again. Everyone else carried (and still should) jumper cables, which require two cars and enough knowledge not to short them out.

They were heavy lead-acid automotive batteries that only garages and tow truck drivers used. Between the invention of the self starter and the end of the 20th Century, the best portable car jump starters weren’t things you carried with you.
