Jackery DC-DC Alternator Charger for Fast and Safe Charging – Black

• Golden 600W Car Power

Jackery’s 600W "golden power" output is tuned to get the most from your vehicle’s alternator without putting it under stress. This balanced power level delivers fast charging while protecting your engine and starter battery.

• Charge While You Drive

No more planning stops around wall outlets or waiting for sunny weather. By using your vehicle’s unused alternator power, Jackery charges while you travel — saving time and making off-grid trips effortless.

• 6× Faster Than Cigarette Lighter Ports
