When I first received the device it was at 69% of a full charge. I plugged it in and 16 hours later it finally reached 99%. This is an unacceptable charge rate.

As good as you can expect for less than $60. I've used it start my truck and my Jinma diesel tractor for this whole winter.The copper colored clamp jaws are actually aluminum and have worn down to where they no longer made contact because the protective plastic covering hit first. A simple cutting away of some of the plastic covering and it was back to business. Very powerful little unit. I've literally used it almost daily for 5months. It does not like sub zero unless you bring it in out of the cold at night. Charges great on a usb c cable for a Macbook Air.

I bought one of these for my wife and I liked it so much that I bough one for yourself. They're good quality and they hold a charge. I've used others that are cheaper and it's not worth it. This is a good price and good quality.

Arrived 76% charged and the instructions indicate it can still charge at 20%, so this is an option to jump start your car right out of the box. If your battery dies and you don't need to move the car anytime soon, this will solve the problem without having to recruit a friend or neighbor or call AAA. Great value for the money even if you only ever use it once, saving time and stress spent negotiating for a jump, calming your uncertainty. It's empowering! And you can help a fellow driver out without moving your car or risking voiding your factory warranty. Also has plenty of ports to charge cell phones and tablets if needed, so you might find it helpful as an auxiliary power source on a camping or road trip. I'm charging it now, it's a beast that will provide lots of power for devices but takes a long time to charge via USB-C port.

I bought this jump box on 07/22/2024 and literally used to the next morning. I own a 2009 Chevy LTZ Duramax Diesel 6.6L. Also I live in Phoenix, Arizona, where batteries don’t last too long. With that said, I put this jumper on my battery and literally jump the truck within seconds love this product went from 100% to 93% in the first shot very easy to use it does charge quickly It was at 73% took about two hours for it to get to 100% definitely recommend this product . Very easy to use. Just make sure the color on the box when it’s blinking red and green is solid green if It’s not solid green. It won’t jump the vehicle. 5 stars all the way.

I don't write a review for every product I buy whether from Amazon or any other multitude of online order products. But when you run across one so GOOD, that it warrants a 5 star rating, you feel compelled to do so. That is certainly the deal with this little gem. After having been jumped started with this exact device while stranded at a gas station despite a failed jump attempt from a car to car from another good samaritan, this guy says here try this. Hooked it up and my big ole truck fired right up. I was even more surprised when he said it was the 1st time it had been used and he hadn't even fully charged it yet, despite having it for about 3 months. I was sold. Had to have it. So I got the info, looked it up and set about getting one. It was already on sale plus a little check mark in the 30% off box combined with a small gift card remaining on my account made this tjing a steal. Order after supper and by 8 the next morning it was on my foor step. WOW! Fastest delivery I've ever had. This thing out of the box is charged at 80%. Seems very sturdy. Comes with a nice hard cover carrying case with a bright red zipper for easy visability. Once charged it will be in the truck at the ready for myself of another stranded motorist where I can repay my pay-it-forward jump.
