The freedom of RV travel relies heavily on the stable power of deep-cycle batteries – air conditioning, refrigerators, audio-visual entertainment, and outdoor cooking all depend on continuous power. However, traditional chargers are slow and lack compatibility, often resulting in insufficient power replenishment during the journey and long wait times for campsite rest. Especially since the 12.8V deep-cycle battery is the core of RV energy storage, a solution that offers "rapid replenishment, dedicated compatibility, safe power protection, and RV-specific compatibility" is urgently needed. We have specially designed a 12.8V RV deep-cycle battery-specific fast charger – eliminating range anxiety with 30A high-power fast charging and protecting the battery's longevity with deep-cycle technology, ensuring every RV trip is fully powered and carefree.

　　Designed for deep-cycle charging in RVs, and for ultra-fast charging.

　　30A high-power fast charging, doubling the charging efficiency: Equipped with gallium nitride (GaN) fast charging technology and an intelligent power regulation chip, it supports a 30A ultra-high charging current (compliant with the 50-90A recommended charging current standard for 12.8V deep-cycle batteries). It can charge a 12.8V/100Ah deep-cycle battery to 60% in just 30 minutes and fully charge it within 2 hours, saving 60% of the time compared to traditional chargers. Quickly replenish your battery while traveling or during campsite breaks, without disrupting your journey.

　　Deep-cycle dedicated adapter for long-term battery protection: Designed specifically for 12.8V lithium iron phosphate deep-cycle batteries, perfectly compatible with mainstream capacities of 50-200Ah, with charging cutoff voltage precisely matched to the 14.4V standard (compatible with the 14.6V maximum charging voltage requirement of some batteries); built-in deep-cycle dedicated fast charging algorithm, employing a three-stage charging logic of "constant current fast charging + constant voltage replenishment + balanced maintenance" to avoid high current damage to the battery, and working in real-time with the BMS battery management system to extend battery cycle life to over 5000 cycles.

　　Customized for RV scenarios, adaptable to multiple power replenishment modes: Supports three modes: "on-board charging while driving + fast charging from the campsite's mains power + solar panel charging": While driving, it can be charged via the 12-24V RV cigarette lighter or a dedicated power interface, with anti-slip spring design ensuring stable power supply on bumpy roads; when parked, it connects to the campsite's mains power for a quick 30A fast charge; paired with the RV's solar panels, the 6-40V wide voltage input is compatible with various photovoltaic modules, achieving dual power replenishment through "sunlight + driving," eliminating range anxiety for long-distance travel.

　　Automotive-grade safety protection for worry-free travel: Certified by CE, UL, and CCC, it features six built-in protection systems against overcharging, overheating, short circuits, reverse connection, overload, and surges; adaptable to fluctuating RV circuit environments, its 85-264V wide voltage input eliminates charging abnormalities caused by voltage instability; IPX5 dustproof and waterproof design protects against rain and sandstorms at campsites, and its operating temperature range covers -20℃ to 60℃, adapting to extreme RV scenarios such as high-altitude low temperatures and desert sun exposure.

　　Convenient operation, RV-specific design: Equipped with a clear LED display screen, it shows real-time charging current, battery voltage, remaining power, and charging progress; uses RV-specific wiring terminals and a 1-meter extension cable for convenient installation and use in various locations such as inside the vehicle or storage compartment; weighing only 1.8kg, it features an ergonomic handle and can be stored in an RV storage compartment without taking up much space, making mobile charging at campsites more flexible.

　　Adaptable to Diverse RV Scenarios

　　Powering During the Journey: During long drives, the deep-cycle battery can be charged in real-time via the vehicle's interface, ensuring full power upon arrival at the campsite. This power can directly power devices such as air conditioners, refrigerators, and projectors without any waiting time.

　　Fast Charging at Campsites: When resting at RV campsites or service areas, a 30-minute connection to mains power can quickly replenish 60% of the battery, meeting the high-frequency power needs for nighttime camping lighting, outdoor barbecues, and audio-visual entertainment, enhancing the quality of life at the campsite.

　　Solar-Assisted Extended Range: Equipped with solar panels on the RV roof, it stores energy independently during the day and can quickly replenish power on cloudy or rainy days via fast charging, achieving "zero electricity cost" green travel, especially suitable for long-term stays in remote areas.

　　Emergency Backup: In case of power outages or insufficient solar power at the campsite, it acts as an emergency fast-charging device, quickly replenishing the deep-cycle battery to ensure the normal operation of communication equipment, medical emergency equipment (such as portable oxygen concentrators), and lighting systems, allowing for a calm response to emergencies.
