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 had my blazer battery go down in charge due to not using it enough. Hooked up the P-ONE and it started easily. Only used 3% of the existing charge. So much easier than moving another vehicle and dragging out jumper cables. I have been telling my friends how well this works, takes up a lot less space than Jumper Cables, and will charge my phone if needed.

This thing is totally worth the money. Not only for jumping your car but it's saved me for charging devices when I'm on the go cause I've ran out of power points. I saw some reviews about people complaining they bought it and tried to use it a year later and it didn't work but like I imagining leaving it in a car year around through heat and cold wouldn't be good for any lithium ion battery but I use mine so much for my hoopty car, devices, and saving other people I bring it in frequently to charge it. 4 months later and it's still works great. I even just now used it to jump a 1992 24volt dodge Cummins diesel. Sucker fired right up and only dropped the supply 6%. The emergency lights and flashlight are great too if you can't get back on the road you can let people know you need help.

I bought this more than six months ago, charged it up, and left it in the trunk of my car as a precaution should I ever be left stranded with a weak car battery. Risk aversion often calls for buying thing one hopes never to need. Well, today that need arose: the car wouldn’t start on account of an evidently too-weak battery. Even after months in my trunk and through a particularly cold winter, the jump starter was still showing a 100% charge and worked perfectly, getting me back on the road an on my way to buy a new car battery. This is a must-have item in any car.

First of all, my favorite part about this car jump starter is the case. As for other models I have, the jumpers and the jump pack itself are kept under separate netting in opposite sides of the case, which isn't nearly as ergonomic as the case for the Powrun unit. With this one, everything is easily accessible, and easy to put back into place. The accessories and manuals, etc. are kept in the other half, behind a netting. As for the jump pack itself, I found it easy to use and reliable in performance. It had no problem starting my 2006 Ford Crown Victoria with a 4.6L V8 that was completely dead from a parasitic drain. One thing to watch out for, is to be sure the jumper cables are fully connected to the unit, and the rubber cover for the plug is not interfering and getting pinched between the two ( I have included pictures of this condition). This led to me having a red light when connecting to a battery. A minor thing to note, but just something to watch out for while using the jump starter. I was also using this unit in the process of working on a stalling vehicle with a dead battery, and had to jump it at least a dozen times total, along with a few uses on a 3.0 6 cyl in an X3. This also includes jump starting the 4.6 v8 several times over a few days while completely dead to give the unit a proper test, and I'm still at 59% battery (which I find impressive). I believe the only thing I would change would be to improve the grommet sealing the connector for the jumper cables. All things considered, this is a very minor concern, and is really the only one I have with the unit. As for the other features, the flashlight is usably bright, and the red strobe could be useful if broken down at night. These units are also awesome to use as a backup battery bank for charging phones while camping or on trips. Overall, I would find myself choosing this item over others just for the fact that they have such a well designed case alone. At this price point, it is hard to beat the amps and capacity that this unit offers, making it a good buy. Given these pros, I find myself placing this above other units that I have (TackLife, Solvtin) and others that I've currently seen on Amazon as far as bang for the buck (capacity, amps) and features. This unit has proved itself, so far, to be reliable and sufficient for my needs and would recommend it to others if you are needing a larger capacity jump starter capable of starting larger engines requiring a higher amp draw.

So I got in my car yesterday to run some errands, and discovered my battery was dead. I had accidentally left the inside light on (the light is SO DIM I forget it’s on!) Sadly this wasn’t the first time I’d done this to myself. Hubby wasn’t home to give my car a jump so I was stranded at home. Since I had thought about buying a car battery jump starter the last time this happened, and had done research already but didn’t want to spend the money, I decided to just bite the bullet & pulled out my phone and ordered this Powrun jump starter while still sitting in my dead car. It arrived the same night! This morning I used it - super easy and it worked perfectly! I was worried my battery wouldn’t be able to be resurrected (it’s definitely on its last life) but using the boost button did the job pretty much instantly. Nice and compact but powerful unit and I love the protective storage case. I feel so much better knowing I now have the tool to jump start my car by myself if ever I need to - or even help someone else out with theirs without the whole jumper cable drama. Being able to charge my phone, etc with it, the led flashlight & compass - all great bonus features. Very happy with my purchase!! Seems well built, hoping it will last me a long time.

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!

Purchased ($64.18) and used for the 1st time in October 2024 The first time I used the starter, it did not work. I think that was more user error because I was not sure how to get it to work. I watched a YouTube video where they mentioned the boost button. The 2nd time I used it (Jan 2026), I was not confident it would work because it was exposed to below freezing temperatures in RI for 4 months. When I turned on the starter, it was 100% charged. I used it to start my car, and it worked! After 1st use, it was at 97% charge. I used it a week later to help a woman whose car. It started the car right after attaching it to the battery. The battery charge dropped to 93%. Note: both vehicles were Honda CRV 3rd and 4th generation. I am impressed that the battery holds its charge despite being in the car in 8 degrees temps.
