POWOXI 50W Solar Battery Charger with Integrated MPPT – 12V Trickle Maintainer for RVs, Boats, Marine & More

Power on the go with an all-in-one solar charging solution

Meet the POWOXI 50W Solar Battery Charger, a compact 2-in-1 powerhouse that combines a high-performance solar panel with an integrated MPPT controller. This streamlined setup removes the guesswork of wiring a separate controller, delivering a simple, efficient path to keep 12V batteries topped up across adventures and work sites.

Smart charging that adapts to your battery and the weather

Equipped with an independent IP67-rated MPPT controller, the system responds to temperature shifts and seasonal changes, adjusting the charging voltage to align with the battery's stage. The three-stage process—Bulk, Absorption, Float—works behind the scenes to support safe, steady charging and longer battery life.

• Temperature-aware charging helps prevent overheat or undercharge in varying climates
• Three-stage sequence optimizes power delivery for diverse 12V batteries
• Integrated protection guards against over-charge, over-discharge, over-voltage, and short circuits

Efficient power, even when sunlight is not ideal

The Power-Point Optimization Incremental Conductance algorithm continuously tests sunlight and adjusts the operating voltage toward the maximum power point. This approach can yield meaningful efficiency gains, especially on partly cloudy days, compared with non-MPPT chargers.

• Algorithm-driven tuning captures more usable energy from available sun
• Up to around 36% efficiency improvement in typical conditions versus basic controllers*
• Quiet, maintenance-free operation for routine battery upkeep

Premium materials and rugged reliability

The ETFE anti-reflection layer delivers excellent light transmission—up to 95%—to maximize solar input. Its UV resistance and temperature tolerance help prevent cracking or fogging over time, ensuring consistent performance in boat bays, RV sites, or roadside stops.

• High transparency and durability withstand outdoor use
• UV resistance reduces aging and maintains clear performance in sun exposure
• Robust, waterproof housing supports outdoor installations without hassle

Versatile compatibility for diverse 12V systems

Designed to work with a wide range of battery chemistries, the POWOXI charger is suitable for boats, cars, RVs, ATVs, motorcycles, trailers, tractors, and more. It recognizes battery type via MODE selection and automatically adapts the charging approach.

• Supports 12V lead-acid varieties and LiFePO4 as appropriate
• Mode selector makes setup intuitive for different battery types
• Automatic charge maintenance stops charging when full and resumes when needed

Simple, reliable maintenance with support you can count on

Beyond the hardware, POWOXI offers a 12-month warranty and lifetime technical support. CE and ROHS certifications reflect a commitment to safety and quality. If questions arise, friendly guidance is just a message away.

*Actual gains vary with sunlight and battery type.
