Works great! 1st day I had it in my trunk, a little old lady at the store had a dead battery. Her car started right up on the first crank. Have used it for other people a couple times more since then. Everyone said "oh I've got to get one of those!"Very easy to attach. No sparking. Must remember to push the override button for jumping dead car batteries.I plan to use this during power outages to recharge phones instead of using the generator.It came with a thin fabric bag that I didn't like much. I would have preferred a case. So I just kept the cardboard box it came in and use that to store it.

I haven't used mine yet (got another as a gift, too), but got the same exact model a friend has. I was leaving work, and my truck battery decided to die that day. I went to turn my key, and only a "click", not even enough to turn the starter at all. I got my friend from inside work to come out and give me a jump start (I had cables with me). Instead, he pulls this out of his car and hooks it up to my battery. I ask him if I wait a minute before trying to start it, he told me to try right away. My truck started up right away! He then told me his starter wasn't even completely charged (he hadn't charged it for a little while). That was it, I was sold! Having cables is great if someone else is around, but what about when nobody is around? This thing covers that! Powerful, and has the other features listed. The only thing missing was a charger. It has the cable, but not the plug. So if you don't have one for this, get that too when you order this (C type charger).

I purchased this think in 2023 and have put this thing to the test, right off the bat when I first bought it, I helped jump a diesel truck with zero, I bought this for the simple purpose of being able to start my bike on very cold days, which it did perfectly fine.Now the real reason for this review was because I had a 2017 Cadillac XT5 that was completely dead and was able to jump it to start. The battery was completely dead and non-reliable, but this little thing was able to be the temporary battery to be able to load it up to a trailer as well as offloaded off the trailer. This thing was able to completely function the car with ease and was extremely impressive. It has been worth every dollar.

I caught Covid and my Jeep Grand Cherokee sat for a week without being started. Went to start my vehicle and no go. My old battery jumper was no longer operating so I picked this one up. Upon first use, it's recommended to fully charge initially. Using the included USB A to USB C cable, the charging could take several hours. Luckily, I have a 60W USB C charger available. This SIGNIFICANTLY drops the charging time. Less than an hour until the initial charge.Once this was completed, jumping my Jeep was super simple. Connect the cables to the booster. Connect to + terminal first. Connect to a ground (Jeep has a post specifically for this). Power on the starter. Cranked up the Jeep. Super easy. Exactly what it should be.It can be used to power up your phone if needed or can even be used in the dark as a flashlight. There are indicators for if the device is too cold (I believe 10 degrees F), too hot, and a couple other indicators. Once I switched over from the USB A to USB C to the 60W, the fast charge indicator illuminated to show that it was rapidly charging. This charger is so much better and more reliable than my last.As others have said, you need to watch the charge of this device. After the initial full charge, charging up to around 85% for standby. I would also recommend occasionally fully draining and then fully charging every so often to keep the battery properly conditioned. This, too, can help to increase the lifespan.Overall, great product. Never heard of this brand until now, but I'm completely on board.
