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, UL Certified
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.
Bought this product. Fully charged and left in the car for emergency. After about 1.5 months, tried to use and did not work. It just beeps and light just blinks. Contacted Tacklife support for warranty and so far only responded with one email asking what is wrong and I sent them a response detailing its defects. Still waiting for a response after 5 days and counting. I sent another response just to follow up and finally they responded that they will send a replacement.
Just an update. So, a total of 9 days to get my part replaced with the warranty. I received my replacement and everything seemed to be working at this time. I was glad that they replaced the defective item and I did not have to send it back because it would have been more inconvenience. So, with that I increased the rating from 1 star to 4 stars.
So far my only qualm is with the instruction booklet. The print is so small that I can't even read it with my reading glasses, except in bright light. I ordered one of those credit card-sized magnifiers to slip in the booklet (found a set of 4 high quality ones for $4.99. Can start a fire with one, too). I think a lot of these booklets are created by people too young to understand that that will be a problem for most after the age of 40. Especially in emergency situations where there is little light and higher stress. Also, the information regarding the LED flashlight is wrong. For that you need to hold down the power button, not the warning button. And there are four selections, including the off, not three. I think there was some cut and pasting that went awry when it was written. So far, everything else is fine. But have yet to use it in an emergency situation. It is compact and solid. Looks well built. Nice case that everything fits into. The cables are thicker than most other kits, which is nice. It's also nice that you can charge it in your car as you would a cell phone with the cigarette lighter, so I think they said it's a bit slower that way.
I like that it holds a charge for a log time. I charged it when I got it in July and jumped my side by side 3 times and it still shows a full charge. I would have given it 5 stars but haven’t gone through a winter with it yet.
Purchased 2 units, one arrived dead the other fully charged. Dead unit would not charge up. Returned and received an immediate replacement from Amazon. I will be watching closely for charge performance. Bought them for the battery storage size for emergency use so don't want to be stranded. The unit is well put together and seems easy to use. I'll be checking it out for month or 2.
I left my ignition on mistakenly for 3 days so I used my tacklife t8 max to jump my 2012 jeep grand cherokee and within seconds it started it was great and it feels very durable I love it no problem so far
