VERY user-friendly, a dumb blonde can look like a pro under the hood with this thing. It literally tells you if you are not hooked up correctly, and when you are, you get the green light to start your car. I feel this makes the product safe to use. It works for a V6-V8 engine; it says it works on a diesel, but I don't have one of those, so it's up to you guys to let us know. It looks heavy-duty and feels expensive. It also has a long-lasting battery life even after jump-starting a dead battery. I highly recommend this product. The only negative thing I can say about this product is that it didn't have a good storage case; it came with a sack, not the greatest.

Excellent. Really amazing. Had a completely dead battery on my Audi TT and this charger in boost mode started the car up straight away. Months later and the charger is still holding a charge. Very good item. Highly recommend. Thanks

Outstanding jump pack. Well worth the money. Cranks my high compression diesel over with ease. Long battery life so you don't need to charge often

Battery life is great even if using multiple times and several devices. It didn’t take as long as I expected to charge either which is nice.

Good size, good functionality.Had to use it before I had a chance to charge it. Worked flawlessly.The self check on whether it's connected correctly is a great feature.Seems to be well built, but can't comment on how long it will last, needs a lot of use over time for that.

Whilst I haven't actually used it yet, it looks and feels like a quality product. I bought this to take on a big trip coming up going across the Nullabor and wanted this in case either I or another traveller needed help. AAA+

I had an issue with another charger that I had gotten from this company. They reached out very quickly and resolved the issue within a couple days

This was given a four stars because I have NOT used it to jump start a car at the time I wrote the review.Out of the this unit seemed well made, as well made as other similar items I have bought. So far I have not had to use it to start a vehicle, but have used for a short time, to see if it worked, on a rechargeable desk light and a small fan. Both have a USB-C plug. When I need to jump start a vehicle I will update this review.
