Seems to help but the wires could be a little longer

Part works well, has slightly reduced light surges and light dimming. Definitely a low cost part imo to help reduce voltage issues.

i’ve noticed that after installing this in my car i’m reaching higher rpms faster and i feel as the car is slightly faster there is definitely more torq and the audio and bass is better but my mpg and range is messed up i’m flying through gas and my mpg went from 31.7 to 19 and my total miles on the car and the amount of miles left on my range is getting drained any ideas on what happened

Works great.

I have only used it about a week, but so far it appears that it is doing what it's supposed to, I tried 3 of the variations listed in the instructions, (different areas that you can connect the Raizin to on the engine) and did notice a slight change In type of performance . So far no complaints, but until it's tested thru a third party and I get a Dyno test comparison of my car, it's just my opinion. Then again it's a straightforward concept so I don't forsee any issues, good mid range construction quality, it does also add a cool look to your engine bay, and having a digital display of the voltage is helpful , it's affordable, quick and easy installation, and I received it faster than I expected.

This is also the sons time I have used this, not really sure how much gas mileage this helps with but everything in my 16 Veloster works better, light brighter my stereo system sounds louder and hits harder. Recommend for any vehicle just as a solid electrical system need .

Great product and what a difference after hooking it in to the battery I would highly recommend

Did not receive my product. Can someone please please contact me and help?

This totally helped cut noise in the cab and it deepened the bass. It also has the truck starting up quicker.

Nice product!

This device corrected the rough idle that I’ve spent months trying to find out what was causing it. Car now starts faster. More power. Radio sound quality is way better.

Going to order another one for our 2019 Cherokee Limited with V6 next. It’s has a Performance Tuning chip already which is also awesome, so I’m super curious how the voltage module will work in conjunction with the chip.

only had it for a few days but idle is smoother, seems to have a little more low end power, a little

Well, I was a little skeptical about the veracity of this module. I had already installed the stage 3 performance chip, I wanted to see if the voltage chip would give it a little goose on the throttle, and in regular driving mode it absolutely did. My Altima has a sport mode, it didn't really affect that. But the regular driving mode absolutely. It also helped with the sound system. Much crisper and deeper. I use the extra grounding cables to ground the engine block around the alternator, also the intercooler area and starter. It was 2 below zero yesterday and she cranked like it was much warmer. The capacitive performance is astounding.

sound vibration improvement noticed in stereo, have not seen any other benefits yet!

Hooked it right up and experienced a difference in the low and mid end of rpm and throttle response.

Works great. Keeps voltage normal.

great looking product! Very easy to install. only had issues finding a secure location for the module.

Yes this thing does work. Installed it on my BMW. So far very happy. Great customer service too!

put this on my suv due to some strange noises i was told could be coming from the electric wiring, seems to actually have made the engine run better, im not one for performance but definitely made my car run better, and im sure thats something everyone likes for a price like this. couldnt have faster shipping for an online store as well..

I purchased this item with their Stage 3 chip, and for my older 996 it definitely makes a difference even my dash lights are brighter

Works really good, especially that i have a a couple of 12" subs in the back no more lights dimming when my base hits

after installation was complete, definitely noticed some of the interior lights and even headlights get brighter!

This product works and comes with everything that you need I'm a happy customer and it dose what it says and shipping was fast.

This product isn't that bad it actually works! After installing it I took my car on a test drive on the highway even though it took a while to feel and notice the difference with the new upgrade, I would most defiantly recommend this product to any person that wants that extra "something" in their car.- plus it looks good under the hood ;)

I just installed this on my Jaguar STR and immediately I noticed a difference...the installation was a little tricky and took bout an hour because the battery is in the trunk. But once I took it on the road I can definitely FEEL MORE POWER! I would guess maybe 10-15 more..the RPM's have changed and it pushes the car faster....I would recommend. Thanks guys!!!

This is one electronic instrument that really works. Easy to install and it last a long time. It does exactly what it says. It's cheap and very very useful. Once installed with a Gounding kit, your all set. It increases torque and power and it helps the electrical system.

I bought this voltage chip because i had new gauges installed on my car and a friend recommended me to try this product out, so i did. It definitely works on making the dash and interior lights brighter, the stereo sounds better, it does add a small gain of power and torque as well, and very easy to install. I would recommend this to any 1.

I almost returned but I quickly change my mind. I installed it and man does this thing work!!!!! Increased power and torque. And my car is alot brighter and quieter and idling is great. More milage too.

i enjoy the product but i was a little worried that it would drain my battery but it hasent so everything seems to be working fine

This is an excellent product. I've used it for many years and its great. No Bull. It has kept my electrical system in check. More power, better lighting, better mileage, and minimal electrical system maintenance. You won't regret it.

Wow! Instant response, big change from what i had install was easy took me about 5 mins. Also added athe supercharger booster, lots of power now
