This has saved my ass several times and it’s also great to have when a friend or family are in the need of a jump. Plus, it’s very easy to operate! Big plus in my book.

I havent actually used it yet but I was pissed off enough to write this. Package came with a thick book in the smallest font I have ever seen. I had to use my mag light on my iPhone to read it. There were no instructions, only warnings in about 20 languages. I had to google the company to find a guide on how to use. the pages shown in the online guide were not in the included booklet. I will followup on the actual use once I get a chance. Now that i found a users guide I am charging the unit. Evermore pissed off since Amazon delivered it to my next door neighbor. Perhaps they could hire people who can read house numbers. Both houses have distinct number signs right out front.

Unfortunately this did not work on my car’s battery (‘07 Lexus RX 350). The battery is only 5 months old and the car was left sitting for three weeks for reference. Per the instructions the white light turned on which means the device was hooked up correctly. I tried starting the car immediately and when that didn’t work I waited 30 seconds as stated in the instructions. Still didn’t work. Tried a few more times and gave up. The return seems to be a hassle for this, Amazon states they will refund me within 30 days after they receive the product. Considering all the good reviews I wish this had worked for my car.

It won’t work at all

does not work

Not worth it. It couldn’t jump a wrx.

It’s an okay jump box but you gotta charge it up all the time, which is really annoying when you need to use it a lot But solid for a 1-3 time use

My neighbor had to jump my car. It happened so fast that I asked him for the link I now have it and the charge stays in it for a long time. Yes you have to charge the charger but like I said it holds the charge. I would highly recommend.

It could not start a single cylinder ATV with battery voltage at 11.9 volts. I even let it sit hooked up for over a minute and NO go. This was exactly the purpose and situation I purchased it for, day ruined could not get out and ride.

I’ve used this the same day I ordered it using same day shipping and my car started with no hesitation right out the box!!! Definitely a MUST to have one of these!
