Pros & Cons
Pros
The supercapacitor is a large capacitor that can start your car. The black box is a voltage converter so it will use a low voktage battery and raise the voltage to charge the capacitor.
The unit is well built in a sturdy case. It's kinda bulky / not integrated, but seem like it will be good long term. The instruction manual is somewhat difficult to understand at first, but after a few reads, i was able to follow it.
Cons
Chinese caps are know to be of poor quality, which is why they only have a 90day warranty. Operating instructions are poorly written. Wouldn't start the dead battery.

Competitiveness
It has this far jumped my truck 4l v6 and a ladys civic
It is a capacitor which accumulates low power from a weak battery and uses it for a highpower jump start
