I actually bought one of these used on Ebay, buyer said he only had it for a short while. Anyways I was cautious about buying a new one at full price because I looked all over the internet and could only find one review. even Power Acoustik themselves is vague about what this thing can really do. After finally having it installed the guy told me it was actually in better shape then the battery running my vehicle. He says it's an interesting piece of equipment inside it has 4 small battaries and four small capaciters. I like the fact that it also reads voltage with the car off it was getting over 12volts and with the car running it was getting well over14volts. I'm using a average battery and a 105amp alt with 0 gauge a Autotek mean machine 1500rms amp at 1ohm and a four channel (rockford 501x soon to be replaced) and so far have had no voltage drops since system install I was at about 13.5 before and remain at 13.5 now and my camaro still has the get up it always did.
