Voltage stabilizer

Was thinking about trying one of these magical voltage stabilizers that add HP and MPG. Had it on my last car Acura TL and it helped with random electrical issues like dim and flickering lights. To me it's a like a capacitor you connect right to the 12V battery. Which I don't mind because I do have subs.

Wondering if anyone has tried one of these yet on a Prius?

 

No clue on why based on their claims but I have no negative symptoms. Hoping maybe brighter headlights, maybe better sounding bass, and or less power drain from running the A/C. It's under $20 on eBay so might be trying this out soon.

 

Very interesting and informative video ^^^^


Got the item in,cost about $16. It's basically a capacitor with a blinky light. Only had it connected 3 days now and the placebo effect is in full swing. The car feels quicker and tires squeek more often in my tiny peel outs attempts or jumps into traffic. No change in sound quality or brightness of the lights. However I have noticed the past 2 weeks when leaving work my hybrid battery is down to like 2 bars after installing this it's usually in the green or full. Regular car battery voltage was unchanged. I've been tracking my mileage in a spreadsheet for the most few months so will post after a couple of fill ups to compare. More testing to come.




When I redo my coil overs I'll remount this and put a sticker over the hole. : )


Bolts directly to the Negative terminal.





Right onto the positive.

 

So this thing seems useless and I think it's going out. The light on it is flashing differently than it was the first month. My HV battery still goes down to 2 bars almost daily. My drag times were worse with this but I also had my subs in on my last run. No improvement in MPG, has actually been on a decline. Think I'll disconnect this thing and see how my MPG goes.

 

I've had subs in since before I started tracking the MPG. Only thing different in my second drag race was that I left my subs in and this voltage box was installed. So it could have been the weight from the subs hurting it. When I dragged I noted that in my spread sheet,got 34.8 MPG but haven't been able to get past 40MPG since putting my bigger wheels on. Did that box at the same time but MPG still went down.

The battery bars will go down to 2 somedays if just sitting. Turn the AC on and it goes down real fast. I just ordered a grid charger from hybridautomotive so we'll see if that helps.

 

Snakeoil to the prius so far yes but it did help on my last Acura that had electrical issues. My 12 V Optima yellow top battery is going strong and I do trickle charge that before races.

When I consider it fully dead I'll take it apart and post pics of the capacitors.

Well I figure I have most my "performance mods" lol done and been traveling more why not try to get back some MPG. Actually tried the EV button mod last night and FAILED. ev button install problem | PriusChat describes my issue.

 

Noticed the LED was blinking erratic last week then not at all this week so I took this turd out. Reconnected it briefly to see if it gets a charge which is still does but I see no benefit to this device. 25V cap inside. Still have it ,maybe I'll put it on my riding mower. ha

 

I'll clean the throttle body and MAF sensor this week. It's been like 40,xxx miles since doing that. How much are 02 sensors about?
