DO NOT BUY THIS PRODUCT
February 1, 2019
THE GOOD: In fairness, this product does work as a portable charger for your electronics. I even used the USB port on the left, which is 5v/2.1A, to charge my iphone 8 using a wireless charging station.
THE BAD: It took me several minutes and multiple tries to get the jump starter to work. It was clear that no matter what I did there was no power being sent to the jumper clamps. The led on the clamp plug was flashing red and green, but there was no power getting to the vehicle battery. In the end I got it to work by continuously holding the button on the plug that connects the batttery clamps to the Beatit D11 while I started the vehicle. Luckily I was jumping a riding mower, so I could reach far enough to hold the button and turn the key at the same time. It would have been impossible to use on a car unless your arms are ten feet long or you have someone else with you. I bought this unit so I could use it when I am alone.
I WAS ALSO DISAPPOINTED because, despite what the description says, after the one jump start that worked, the battery went from 100% to 25%. And yes, I checked the battery life display after each attempted jump. Then, to test it, (after I moved the mower as needed), I tried again. Despite holding the button, it took several more tries before it actually provided power to the battery (there is a voltmeter on the dash of the tractor). It did work a second time, but that took the battery of the Beatit D11 from 25% down to 10%.
The unit seemed to have ample power to start the vehicle, but the difficulty using it and the rapid loss of battery life confirmed that this is not a good unit. NO, I would not generalize that all of these units are worthless. Our daughter was given a jumpstarter that looks identical to the Tacklife T6 (on Amazon) but has a different brand name... I think it's LifeStart or something like that. It works great. It can jump multiple cars without recharge, and works the first time, every time.
