Top positive review
Stronger than any conventional jump-box.

Alrighty, so I put this thing through it's paces, and all I gotta say is that there's not much else that's this good and this price.
So to start, it was -5 today in the Catskills of NY. I had to jump-start three cars. A 2004 Volkswagen Touareg, a 2012 Volkswagen Golf, both TDI engines, and a 2006 Mazda3.
Some background on these engines, they are Diesel engines and one small gasoline engine with NO alternator output.
The CCA required to start the Touareg is 900, and for the Golf is 800. For the Mazda, it's 660. Well, it started all 3 with no issue while covered in ice and snow in frigid cold weather. The cables didn't get hot, the battery pack didn't get hot, and when they cranked, they all sounded like they had a full battery.
Now, I'd like to explain why this jump-starter has an advantage above all the others. Most other lithium starters have 3 batteries inside that are rated 3.7V nominal, and when fully charged they will be about 4.1V per cell. This means they will put out roughly 12.3V. Well, this one puts out 16V when the jumpstarter is active. This is the advantage. When cranking, this jump-starter dips down to about 11V rather than 10V like the others, this is very good for cranking as it gives more usable voltage for cranking an engine and allows for higher amperage to be drawn by the vehicle's starter. All in all, this one shines high above the rest at it's price point. I must say, I will be purchasing another because I'd like to have one in my car for any emergency.
