Amazon.com: Customer reviews: TACKLIFE T8 MAX Jump Starter - 1000A Peak 20000mAh, 12V Car Jumper (All Gas, up to 6.5L Diesel Engine), Auto Battery Booster, Portable Power Pack with Smart Jumper Cables, Storage Case
I let the battery completely drain on purpose by leaving the headlights on to test out this battery charger. I have a full size Chevy Silverado with a V8 and this jump starter started the truck right away. Very impressed with this device. No longer would you have to wait for someone to come by with jumper cables or another vehicle.
I purchased this product Nov 1, 2018 through Amazon. I fully charged it as indicated by all indicator lights lit and put it in my vehicle for emergency purposes. The instructions suggest to recharge it every 3 months or so. Since I am about to go on a trip I pulled it out to do so, and found it was completely discharged. I plugged it in to the house current as instructed and the first light started flashing. In 4 hours the second light started flashing so I left it plugged in overnight. This morning the two first lights were on steady. I unplugged it and lightly tapped the power button and the first two indicator lights and the forth one came on momentarily and the went out. The third indicator light did not come on at all. At this point I am unsure if I have a fully charged unit or not, or do I just have a third indicator light that is not working. What do you think?
This was shipped from California. Because of the battery, it could only be shipped by ground transportation. I waited anxiously for about a week to get it. I needed it to jump start the dead battery in my wife's car. I am very disappointed that I couldn't even get it to turn over the engine. I followed the instructions. When the light turned green, I pressed the boost button. The car alarm activated but by the time it took me to hop into the car, it would fault and the red and green lights would flash. Apparently this is some sort of protection mode which will turn off the battery pack power. I can only assume that either it cannot start a completely dead battery, is under powered or defective. It's warm outside, I doubt that this could even start a partially discharged car battery in the cold of winter. I will probably return it.
9/12/19 - I did decide to return it. I'm disappointed that I had to do this because it seemed to be well made. However, if it can't start my wife's car, it's of no use. The two star rating is because of the fact that it looks well made and may in fact start a car with a partially charged battery and not a completely dead one.
Lawn mower battery wasn’t spinning the motor fast enough to start. Hooked up the jump starter and it spun it a little fast but not enough. Unless this is a lemon there is no way this is starting a 6.5 diesel.
I bought this for obvious reasons. No it did not work for me. Lightweight and not a confident feel about it. The battery clamp covers overlap the teeth so much you can't get a solid bite on Chevy side terminals. On a positive it comes with a nice case.
