Reliable charging protection through a built-in cooling fan, which keeps the DC to DC charger operating in optimal condition even at high temperatures. It includes overvoltage, undervoltage, reverse polarity, overheating, and short-circuit protection, helping extend battery life and ensure safe charging.

Wide 12/24-12/24V voltage with four charging modes: 12V to 12V, 12V to 24V, 24V to 12V, and 24V to 24V. Suitable for RVs, caravans, trailers, off-grid systems, and home backup power.

Wide battery compatibility with LiFePO4, Lead-Acid, GEL, AGM, and Calcium batteries. Works with over 95% of portable power stations and includes 2 DIP switch buttons for quick battery type selection.

Emergency reverse charging allows charging from the auxiliary battery in case the starter battery is depleted, ensuring quick restoration of operation without waiting for roadside assistance.

Fast charging performance delivering up to 40A and 520W with efficiency up to 94%, faster than a standard car cigarette lighter charger. Supports solar panel input as a backup power source and features built-in MPPT technology for optimal solar charging performance.
