Pretty decent for the money

The unit started several vehicles and was used to raise and lower the jack on my camper several times on a single charge. I would have gave it 5 stars if not for the fact that when it shows 1/2 charge on the indicator the thing is actually done it won't even jump a lawnmower at that point. But I would have to say I would buy again oh and one more thing that could be better is the cable length maybe add a few more inches to them
So easy to use. Saved my ass on the side of the road.

10000x better than trying to hook up another car with jump cables. The light turned green, and i started my car, that simple. No revving, no funny business. I needed a new battery but this got me to the auto parts store.
Perfect for any family

My car would not start after state tournaments in town 4.5 hrs away. Late at night and didn't know people to get jump start. Having this was truly a life saver for me or I would been stranded with grandkids having no way to get home or even to hotel!
Works reliably

Bought this because every time I've bought a "cheap" jump starter in the past it's worked fine when brand new but didn't last long. Decided to spend a bit more for a better one.
I bought this one in particular because it tested well on the Project Farm channel on YouTube.
I've only had it for a few months so far but it does seem to be holding up extremely well. I really like that you can charge it via USB-C instead of needed a proprietary charging cable.
Only gripe is I have to press the boost button every time I use it even if there's enough charge on the dead battery to wake up the car's electronics. I would have thought I would only need to use the boost button if the dead battery was _completely_ dead.

I found myself with a dead battery after leaving my headlights on at the doctor's office on a rainy day. I had nothing with me to jump start my car, so I researched and the yesper seemed like a good option. I bought it and I've used it to start my cars 3 times, a stranger's car once, and my riding mower once. I bought a 2nd one so I'll always have one in each car. One of my cars is push button start. It had sat for 3 weeks and the battery was too low to start it. I left it alone for another 2 days, but I forgot to push the button again to turn the car off, so the battery was completely dead when I jumped it 2 days layer. I had to use the boost button, but it instantly fired up. The yesper is a great product.
