Powrun P-ONE Jump Starter, 2000A Portable Jump Box - Car Jump Starter Battery Pack for up to 8.0L Gas and 6.5L Diesel Engines, 12V Battery Jump Starter with Carry Case (Orange)

This is an amazing product! It is small and lightweight but still powerful enough to start my car with a completely dead battery. So easy to use. I am a 68 year old woman who is not strong or fit. I found this easy to use with no effort. It is compact with a carry pouch so it is convenient to take with you. Recharging is easy, just plug into a USB port. It has a light and a small compass as part of the charger. You can even use it to recharge your cell phone.

I've waited to review this item, purchased Nov. 2024, until using it a number of times in all the different modes. First, as a car/light truck battery booster: I've used this thing 3 times; twice on dead battery's and once on a weak failing battery. All three times it hard cranked and started the vehicles as advertised. All three were during below freezing weather. Second, fast charging our smartphones during a prolonged power outage. Fully charged 4 devices and still showed 93% remaining charge. Third, I let this sit for 2 months (fully charged) in its case on a shelf in the garage. The weather is starting to cool here and I thought I'd throw it on the charger to make sure it was ready for action. It was still at 100% charged! For the money, this is probably the best value I've ever found on Amazon to date. Everything you need (charger, high current battery clamps, etc.) are all neatly stored in a hard-shell case along with the charger pack. Highest recommendation from here in the midwest US!

I’ve used this jump starter on my Subaru Forester, and it worked flawlessly—even when the battery was completely dead. I just hit the boost button, and the engine came to life without any hesitation. Each start only used about 5% of the battery, which honestly surprised me in a good way. I also use it regularly on dealer cars at work, and it has never let me down. Different models, different conditions—same reliable performance.I also used for charging my phone and other re-chargable devices flawlesly. The Powrun P-ONE has basically become my go-to tool because it just works. No stress, no second guesses. Totally worth it.

I’m very happy with this jump starter so far and would absolutely recommend it — especially to women. The other morning my car battery was dead because I’d accidentally left the cabin light on. The device was easy to use, and my car started immediately. Having something so simple and reliable on hand is incredibly reassuring.

TL;DR: Very easy to use, convenient size. (See photo for scale) If your battery is totally dead, you may need to wait 15 minutes to be able to start car. I have a car with a battery that is very easy to accidentally drain. It’s a known issue that I didn’t know when I bought it. After needing a few jumps, I bought this to make sure I can always start the car if I’m in more remote places. If my battery is totally dead, I need to connect this and then use the “boost” button several times over 10-15 minutes to actually start the car. However, given this unit’s low cost, small size, and ease of use, I don’t mind too much. It can be a little harrowing to wait if you’re out in “The Hills Have Eyes” territory, but it will work. Eventually. If you need a unit that fires up your car quickly, you may want to spend more for a larger one. I am not sure how very cold weather would affect its functionality, either.

Great product. Not only did it save me a couple times when my car battery died. Got a storm recently and it kept my phone charged. Got multiple charges out of it.

Wow! I own a 2007 Acura TL with really low miles. Not a big driver so my battery goes dead more than it should from neglect. The AAA guy and I are BF. My neighbor has one of these so I decided to buy one. It worked in the first try. My dad did teach us about cars and it’s only a battery. Any one can do it. All women (and men) should have one for safety has a flashlight, can charge your phone, jumps the car, easy to carry. I’m very happy. If it dies or becomes unreliable I WILL update. Oh, it was a great price. :)

It works great, but keep it charged up. It doesn’t work great at less than 80%. I’m old and often don’t drive for long periods. Rather than pay my repair dude to come start it, thought I’d try this. Didn’t think it would work by looking at it. But that little box has some power to it! Best Buy for 2025.
