We have an older hobby vehicle that tends to sit for long periods and need a jump. Even with a completely dead battery, this device started it right up no problem! You get multiple starts from one charge, too. Very easy to use and feels safe. I think everyone should have one of these in their vehicles, it's so much better than jumper cables for so many reasons! Easier, safer, and don't need another vehicle. Alternator goes out, you can still jump your way to a destination in many cases. Well worth the money and this is a reliable and user-friendly brand.

I bought this after having another brand that didn't work for my truck. Mr truck has a coil that has to heat up before you can start and this thwarts the previous chargers I have bought.I have an 18 y.o. 3L turbodiesel truck that has an electric leak so it constantly drains my battery.My truck wasn't started for a month and the battery was dead. There was nothing, no clicks, lights, no power locks. Noting.Clipped this on, pressed the boost and heard the alarm beep.I walked around and started the truck the first time. Nothing else to say but this is worth the money

I waited to review this until I had owned it for a while and had a chance to use it a few times.I have an older 8 cylinder car that I use infrequently that also has an electric issue. The battery drains if it sits. I purchased this charger to keep in that car just in case. When the battery drains, it goes DEAD. i have now used this to jump the big 8 cylinder several times, it works instantly. I can get 3-4 jumps out of a charge.I also take this out on my boat as backup and as a flashlight if needed.The usb-c charging is nice since that is what my phone now uses, so I have multiple charging options.Overall this was more expensive than the models I was looking at but I’m glad that spent the money. This is a great charger.

I could not believe this lite little box would start my completely dead diesel engine (3.0L), but it did effortlessly! It seems to hold a charge well (I check every 2 months and it looses very little charge in between checks. Built in light very handy when anything on vehicle at night. Very compact, easy to store under seat.

I purchased this product less than two years ago and only used it twice during that time, both without issues. However, yesterday, my car battery died after sitting idle for a few weeks over the holidays. When I attempted to use the jump starter, I noticed the battery was low, so I plugged it in to charge. After about 30 minutes, I checked on it, but all the lights were off. I unplugged the device to see if it had finished charging, but it wouldn’t power on at all.I reached out to the company for support, and they said it was broken, and since my unit was out of warranty, the best they could offer was a 35% discount on a new one. For such an expensive device, this resolution feels inadequate. It's disappointing that the company doesn’t stand behind its products longer. I won’t be purchasing from them again—back to reliable jumper cables for me.

Awesome jump starter!! My work car has some sort of electrical issues so I have to jump start that car about twice a month. I've also jump started an old 1980's V8 truck. Be prepared and get a quality jumper and always have it in your car!

Over all decent now that I know to use over ride button. I dont like the very short cables, should've been 2" longer each. I put on a totally dead car and would not do anything and I was just about ready to pack it up and buy a regular booster pack, but then saw the over ride button. After pressing and holding over ride button, worked good and started 2 dead cars but was quickly down to second red charge light.One thing that is really lacking is a high wattage usb charger to plug in to. This thing really takes a while to charge with a normal phone usb.

Size of a tissue box but will start an HGV. Simple to use, keep it in the car, you won’t even notice it’s there. You will however notice it’s not there when your battery is flat, the car won’t start, it’s pouring down and you have no phone signal.

Funziona molto bene, ha anche una funzione di override per disattivare le protezioni e innalzare la tenzione, ottimo anche per auto elettriche con batteria dei servizi a 12V in panne.
