FLYLINKTECH Car Jump Starter, 1500A Peak Portable Car Battery Starter Booster Smart Safety Clamp (Up to 8.0 Gas or 6.0 Diesel Engine),16000mAh Power Pack with Quick Charge 3.0,LED Light

Works great I e been using it to start my 4 wheeler surprised how many times I can start it before a recharge. I also tested it on my car, a 2001 Toyota Celica GTS, and I unlhooked the cars battery completely and this jumper pack started it with no problem. It's best not to leave it connected after your car started because a cars alternator it's designed to recharge the lipo battery in the jump pack. The adapter has a green and red light that flashes when it's ready to use. If you leave it connected with your car running it will disconnect it as a feature to prevent it from damaging the jumper pack and you will notice only a green light flashing not both the red and green lights. To get the jumper pack to work again you have to disconnect the jumpers adapter with the alligator clips from the jumper pack and reconnect. Then the lights will flash both red and green and it will work again. It's a safety feature it's not broken.**Update** 1.5 years later and it still works great 👍👍👍

Easy to use. Keeps charge well under extreme conditions for months in the car. Had it for less than one month when I helped my first of several people that needed their cars jump started. One motorist was stuck in a parking garage because the tow truck was too tall to enter. The charger worked the first time. The guy who had been trying and failing with jumper cables was not too happy about it. The woman asked where she could buy the charger. I was happy to recommend the product. I gave one as a present because it also has an emergency strobe feature.

Works as expected.

I bought this whole driving a friend's loaner vehicle with a cheap battery. Barely started when it was in the teens here so this was insurance.Forgot and left the headlights on one morning at work, the battery drained and I remembered I had this with me. Worked like a charm.

Exactly as pictured. I actually prefer this jump kit better than what AutoZone had to offer for triple the price and I’d definitely recommend it.

The first one we received would not start a Honda 4 cylinder. The company sent us a new one. My husband left the overhead light on in his car so he could test the new one. The new one won’t start the car either. We are fortunate to own a five year old Stanley we keep in our truck that works every time. My husband had purchased this for my 6 cylinder SUV but obviously he will just put it in electronic recycle as the return date has passed. We do not recommend.

Very nice item came in a nice case also it was easy to use from charge up I have not jumped the battery with it yet but it looks like a well made product

I ordered your Flylink jump starter and I knew it was an item that a person wouldn’t be using it a lot. Ive used it one time, and I know you don’t have to charge it very often. With our recently snow fall and extreme cold temps I put it on charge for couple 2-3 hrs and the charge light shows all four lights are on showing it’s charged but when I unplug it, the charge indicator lights doesn’t come on at all and it has no charge. Could it be possible that it may be the battery pack ? Thanking you in advance for your time and I hope maybe you will make things right. Thank YouPenny Duncan
