![]() If you don’t happen to have a set of jumper cables and another car nearby to help, it can get even worse. I have only needed to top them off maybe three times in the 4 years I've had them.Īnybody who’s ever been set to drive to work and found their battery dead knows what a damper that can put on your day. I check it twice a year, before and after winter. The nice thing with them is I can jump multiple vehicles, and the battery doesn't deplete itself over time very quickly. ![]() I sold the V8 vehicles last year, but if I run across someone that has one my 4000A is more than sufficient. I like the battery packs, my daughter has one of the 800A versions in her V6 Charger, and my wife the other one in her Jeep. So I upgraded to an overkill 4000A, 26800mAh that can start a 10L engine. I found it started my Durango fine, but wouldn't start my 392 Charger when I got it. ![]() I upgraded my battery packs to GooLoo, and I got 2 of the 800A, 18000mAh packs that start up to a 7.0L engine for my 5.7L Durango and the other for a V6 Pentastar Charger. Over the years I got bigger engines, namely a 5.7L and a 6.4L. My 1st one was cheap, and I don't remember the name, but it was too weak to jump more than a few vehicles, and didn't keep it's charge long either. I've gotten a few of these over the years as well. But this new option can start a gas engine up to 7.0 litres in most conditions without any of the risks of a lithium battery sitting in your trunk. So we understand if you decide to stick with old tech. So as long as you have some power left in the battery, a supercapacitor converts that small voltage into the voltage needed to start your engine. It can store up to 800-amps this way and can then deliver all of that power at once back to your car when you want to start the engine. Below 11 is where you'll probably need a boost, and below 9 volts your car is effectively "dead" as far as lights and gauges and the ECU are concerned.Ī supercapacitor booster pack draws the low-voltage power remaining in your battery and stores it as 12V power. ![]() The big difference with a capacitor is that it can't help you if your car's battery is fully drained down to near zero volts. Why? The innovative design uses a supercapacitor instead of a battery. The Supercap2 was recommended by itoredmond. So, without further ado, here are the best portable jump starters for Wrangler owners. There are several features to decide on, so we also posed the question to the community. Some of the better packs have a light to tell you how much charge they have remaining. So check your portable power pack at least once a month and give it a charge as needed to make sure it's there for you when you need it. Our pro tip: A battery booster won't give you a boost if it's dead too. Some of those are great, and some of them aren't necessary, but what you want is up to you. From there, everything else is an added bonus feature. They have a small 12-volt battery with enough power to crank over your engine enough times to get it started. Portable jump starters, also called battery boosters, jump boxes, and probably a handful of other nicknames all work the same way. Only one of those options lets you get your car started immediately and by yourself, and it's the same option that actually can give you handy portable power whenever you're away from a wall socket. You can get one by calling a tow truck, by relying on a set of jumper cables and the kindness of strangers, or you can get a portable jump pack. Whatever the reason for your dead battery, if your car won't start there's one solution: You need a boost. An empty battery in your car can come from far too many reasons, from a battery nearing the end of its life to somebody accidentally leaving the dome light on. Own and drive cars for long enough, and you'll end up needing one sooner or later.
