NEXPOW Battery Jumper Starter Portable,12V Car Battery Jump Starter Power Pack with USB Quick Charge (Up to 7L Gas or 5.5L Diesel Engine) Jump Box with Built-in LED Light

I have 3 of these devices - 2 for the car and truck, and one for the tractor. This unit is effective for starting a dead or low battery on various vehicles including the Camaro SS. I had the charger sitting in my car for about 6 months before I needed it and when my battery died, I plugged this in and it started right up. The charge appears to last for extended periods and can be used multiple times before recharging. Highly recommend.

First time purchasing a jump pack. I didn't know what to look for or what to expect, but I saw this on sale and went for it.I was shocked by how easy it was to use, along with its effectiveness. I was working on a 2010 Hyundai Elantra that had power to radio, heat, and lights. One minute of this product clamped to the car's battery and it started no problem!!Another vehicle I was working on was a 2000 Ford Ranger, and that battery was completely dead. No lights, radio, or anything. The device sensed that the battery needed a jump, and you could hear a intermittent 'ticking' inside of the device. And again, to my surprise. . . First try and boom, the truck started!Overall I'm very impressed. I tried jumping the truck via jumper cable and another vehicle, but it must have just been so dead it didn't work. I would highly recommend!!

I tried it on an old battery that wouldn't hold a charge and was setting out in the weather on the ground for a year. The unit worked on it and spun the engine over fast! I discovered that you have to hurry and turn the ignition switch on after you hook it up because after maybe 15 seconds it will go into a disable mode and want do anything. Also I noticed that some commenters complained that it would not charge their phone. They probably didn't know to push the red button on the front to turn on the phone charger.

Clamps suck. They Pop off if you look at the wrong, but once we got it to stay put it got the job done. Saved us a ton of money getting this instead of a service. Now we can also take this on trips in case our old car or someone else needs assistance.

Compact, easy to charge, everyone should have one for emergency. Gone are the days of needing huge jumper cables that take up so much room in the back of your car or SUV. Just make sure to keep charged because you never know when you'll need it.

Put this in my wife's Lexus RX330 with 3.2L engine. Some issuies because of my carelessness in not tightening battery terminal connectors after stereo upgrade. We had to jump it 4 or 5 times until your faithful servant here finally figured out that it was not the alternator or battery, but a less-than-competent mechanic. Ever been there?Anyway, this worked flawlessly. Just make sure to fasten the battery clips securely, press the triangular button and you are good to go. Keep it charged and in the glove box. Light weight. Built-in flashlight. Capable to charge phone, etc. Great price for this. I can recommend it.

This is a great product everyone should have in their car!! Easy to use and small. Life saver.

I have to admit that I luckily have not had the opportunity to use it yet. My car is still starting on its own. However my car battery is getting old and I wanted this as a safeguard in the event the car doesn't start. I gave this product a rating of 4 stars because initially the first one I received wasn't able to charge fully. SO I contacted customer service and Alisa was very helpful and after a few emails, she sent me a new charger. So I am very happy about the way it was handles. Once I actually use the product and it works I probably would up my review to 5 stars. It seems easy to use and the price was reasonable.
