Always Starts Your Car

Even in extreme cold, low voltage, or remote areas. Delivers up to 700A peak current, ignition even at 5V.

❄Extreme Weather Ready Reliable from -40℃ to +80℃.

Protects Your Battery – Reduces strain, extends battery lifespan from 2 years → 5 years.

When starting your car, the Booster’s supercapacitors deliver the high peak current first, so your lead-acid battery doesn’t need to release large bursts of power.
-The battery only provides light support → less stress.
-Prevents deep discharge & high current damage.
-Extends battery replacement cycle, saving costs and reducing waste.
Without Booster: battery voltage drops to 8V at start → damages battery plates.
VS
With Booster: voltage stays above 11V, capacitor handles the current spike.
Result: 80% less damage, battery life extended from 2 years → 5 years.
