Voltage Stabilizers

I thought I have the best Voltage Stabilizer as I have bought it from Low Yatt forummer that claims his VS is 90,000micro farad. Its a home made VS and performs relative well, cost only RM150.00

But recently I came across another VS..34 millions micro farad thats 380 times more than my VS!!...

So, will this VS improved the whole electrical flow on my car?? Thats my SGD400 question. According to the owner it works well on his car but not sure if it will improved on the ICE as he dont have any ICE fitted in his car. I'm drooling with this VS..34 millions micro farad.
