Are you thinking about getting a voltage stabilizer? Voltage stabilizers help balance out the whole cars electronics, basically distributing all the power evenly. There are some benefits of getting one.

The Bellon Voltage Stabilizer in particular have these benefits and for the majority of other stabilizers:
- Increase torque and horsepower.
- Improve fuel efficiency. Save 10%~25% more gas.
- Improve engine response. Quicker Engine Start; Better Throttle Response.
- Stabilizes idling as well as increases air conditioning efficiency.
- Quick engine start by improving ignition system.
- Lesser engine noise.
- Optimize electrical equipment performance to extend the lifetime of car.
- Build-In Electrical Noise Filter. Reduce stereo’s interference and improve the brightness of headlights.
Well, the only difference I felt was a better engine start and throttle response. Whats really cool about this product in particular is that it has a built in LED screen that monitors your the battery and your engines generator. When the engine is turned on it monitors the generator and when the engine if turned off, it monitors the battery.
- For Battery: If the LED is lower than 12.1 it means that the battery is getting really old and needs to be replaced or recharged.
- For Generator: If the LED is lower than 13.5 it means that you should check the generator.
WARNING: Don’t buy those $20 one that states all these stuff. I once ended up buying one of the $20 stabilizers and then opened it, there was only a light that just need a positive and negative terminal so it can flash. The real one range from $50 to hundreds. So please take this into consideration. Don’t buy those cheap ones.

Installation is pretty simple, just connect the positive and negative to the correct battery terminals.
