    • Quick and easy to use. Holds a charge.
Easy to use and it works great! It holds a charge so it can be stored for a while and when you need it, it’s ready.

    • This thing is kinda like having a car starting super power
I found out about this product several years back from a tow truck driver. I had called him to tow my car to a local mechanic's shop because I just couldn't get the engine to turn over. I had charged the battery for about 24 hours using my trickle charger, then I tried it on jump start, then I tried it by directly jumping from another car. Needless to say, I was skeptical when the tow guy pulled out this little box. I let him try it though, and to my complete amazement, my car started immediately. Well, I still had to pay for the tow, but I learned a VALUABLE lesson that day. I purchased one from Amazon at next available opportunity, and I found it so incredibly useful, that I insisted on buying another one for my son's car when he started driving. I've lost count of the amount of strangers I've helped out with this thing. I just pull it out of the wheel well, walk over, and ask them if they want to try it. The feeling of amazed relief that comes off these people when I can help them is worth the price of this thing alone. Much less the amount of money and headache it has saved me and my family directly. After yet another incident last night where I was able to help a stranded motorist at my local grocery store, I realized that I needed to write a review of this thing. Everyone should have one. This poor lady had been stuck in the parking lot all afternoon, and I was able to help her get her car started before the ice I just bought had time to begin melting. Seriously, 5 minutes tops. This thing is a total game changer. It's a great product. It will pay for itself the first time you have to use it. It will literally bring joy to strangers. Buy it, charge it, throw it in the trunk, and check it every few months. You will never be stranded due to battery problems again. ... show more

    • One of my best purchases from Amazon
This thing is amazing. I can't believe I hesitated to buy this product. Here is my story: This past Sunday I woke up to my 2014 BMW X5's flat battery. There was a cold snap and within a couple of days my battery was dead. The last time it was functional was Friday night. I called my auto shop on Monday and due to pretty much everyone in the area having dead batteries due to the cold snap, I couldn't get an appointment for a week. I didn't know if I should jump it, or call roadside assistance and drive it around to make sure the battery was fine before next Monday. Instead, I took a chance on this wonderful device. It came yesterday and I was already impressed with just the packaging. It's minimal, sturdy, and accurate. Straight to the point packaging. I opened it up, and started charging the remaining battery. Apparently, it comes 75% charged and you have to do the rest. I used a USB-C cable from my computer and charged it full within minutes. By the way, the USB slots on this device are USB-C. I've seen a few reviews say that it's MicroUSB. The one I purchased is USB-C which was another plus since you can use this to charge your phone. Fast forward to this morning. I let my car sit for another day, which I thought may have been a mistake. I went down to try to use this device to re-awaken my beast... his name is Benny. Benny the Beemer. Anyway... I attached the positive and negative clamps to the posts under my hood. For most BMW owners, those posts are connected directly to the battery which (in)conveniently is in the trunk behind a electrical trunk latch. BMW did a solid adding these posts under the hood so you didn't have to mess with the trunk release. I turned the device on and the light appeared, but the LED's for Boost weren't "chasing" as the manual says. I figured my battery was completely deceased and I would have to call for RA or a tow. I checked the manual again and I missed the spot called "Manual Override". Now, as a sci-fi geek, this intrigued me greatly. Manual Override you say? Yes, if your car has a completely flat battery, so flat that the device cannot detect that it's even connected to a battery, it will not function within the safety limits. Meaning the device doesn't know it's connected to a battery so it will not provide the 2A charge for safety reasons. That's what the Manual Override button is for. I love it. As soon as I pushed that button, the car came to life. It was like Frankenstein's monster. Everything negative turned positive (NPI). See, the Manual Override sends the 2A charge without verifying it's connected to a battery. This lifts the dead battery to at least 2A so you can try and start the car. The car came to life, the alarm started blaring so I jumped into the drivers seat, said a split second prayer to the car gods, and VROOOM! Benny was alive. This device is amazing. I will be buying one for everyone in my family. Everyone should have this device in their car. If it can bring back my 2.5T 11 year old 3.0L twin turbo beast, it can bring backs yours as well. This device can handle anything up to 6.0L for gas and 3.0L for diesel. Buy this now, especially if you live in colder climates. ... show more

    • WORTH EVERY PENNY!
I purchased this over a year ago cause my mustang battery just died all the damn time. I have used this bad boy dozens of times for myself and even helping stranded strangers on the side of the road. IT IS AMAZING. The last couple times I used it, It had been charged fully, used once then put in the back seat for 3 months, at which time it worked LIKE A CHAMP. There is no better jump box on the market for the money. It has Jump Started full size trucks, A Corvette and a Hellcat. and the best part is, ZERO waiting. hook it up -- start the car. amazing product. ... show more

Nice and compact - but it would be nice to have a user guide included and a charging brick to go with the charging cable.

Review Image by John Wittle John Wittle
I'm dealing with a hard to diagnose parasitic drain somewhere in my car, these new cars have so many electronics it's hard to tell what's causing the issue. But it means that if I don't drive my car for a few days, the battery dies. I bought a couple portable jumpers and tried them all, and NOCOs are leagues above the competition. This product is genuinely incredible. This can start my car four or five times before going dead, and of course, with USB charging, I can just charge the jumper itself off of my car once the engine is actually started. Pure self-sufficiency in emergency, as long as I have a tank of gas. On top of that, the flashlight is great, and the usb out for charging my phone might come in handy one day. But honestly, the main draw is just the ease of use. All of the other portable jumpers either required me to set the voltage setting, or made it unclear to what degree they were charged, or included instructions for jumping that were more complicated than just "red to red, black to ground, turn the key". This one really is that simple. It would be a steal at twice the price. ... show more

    • Works like a charm
This thing saved me. Car was dead, hooked it up, started right away super easy to use and small enough to keep in the car. Glad I bought it. It’s now a permanent part of my emergency kit. Highly recommended for peace of mind on the road.
