Waiting for Zaptor dismantled picture. But looking on Power Booster, indeed a bad QC. Hopefully IceCube can comment on this QC.

Just to clarify for both Zaptor and Power Booster.
Ceramic capacitors is also consider a single capacitors. Maybe inside Zaptor got 3 ceramic type? (small size)

Depend on what you want for VS.

Low uf ceramic used for high freq response
High uf Electrolytic used for low freq response

I really hope Zaptor Gold Edition QC better than Power Booster or Silver Edition.

At this point, Zaptor Silver Edition QC doesn't really better than Power Booster.

IceCube, I am not siding anyone here. But as a seller, at a very least try don't attack someone (potential buyer) that don't have any knowledge on Voltage Stabilizer or capacitors.

You should try to explain that there is not much difference between big and small electrolytic capacitors. Not simply "shoot" him. Many potential buyer think twice after saw such post from seller. Usually buyer will prefer someone knowledgeable on his product rather than spend his time "shoot" other person.

P/S : I am not saying Zaptor seller got such knowledge as well. They attacking on water proof evidence. I am really eager to see which capacitor that they install inside Zaptor. Hopefully not the low end type (easily get at Jalan Pasar)
