$75.99

  • Get Ready for a New of Solar Charging: Enjoy smarter, high-power charging with the POWOXI M-Series High-Power ETFE Thin & Flexible Solar Battery Charger, featuring a fully potted and sealed IP67 waterproof independent MPPT charge controller built right in—no more searching for a separate controller, as we now offer this convenient 2-in-1 configuration to make your charging experience simple and effortless
  • Enhanced Independent MPPT Controller: POWOXI’s innovative IP67 potted technology ensures your solar trickle charger can handle any wet environment. It intelligently adapts to your battery’s temperature across different seasons, delivering the precise charging voltage needed. With a three-stage charging process (Bulk, Absorption, Float), it recognizes and applies the perfect voltage for every battery phase, providing more effective 12V battery charging, superior safety, extended battery life, and enhanced charging performance
  • Advanced P&O Incremental Conductance Algorithm: By repeatedly disturbing the voltage and testing different sunlight intensities to continuously adjust the charging voltage, the operating point of the solar system charging power gradually approaches the maximum power point, improving the charging efficiency and effectively increasing the charging efficiency by 36%*, ensuring superior performance even on cloudy days compared to non-MPPT chargers
  • ETFE Anti-solar refraction Material: ETFE’s exceptional light transmittance (up to 95%) significantly enhances solar cell efficiency by optimizing light delivery, making it perfect for a solar car battery charger and solar trickle charger for car battery 12V applications. Its high transparency is maintained long-term, while robust carbon-fluorine (C-F) bonds provide superior UV resistance, preventing embrittlement and degradation, and ensuring excellent tolerance to harsh temperatures and corrosion
  • Comprehensive Battery Protection: Select your battery type with the MODE button, 12V AGM GEL LiFePO4 and Lithium, This solar battery maintainer is compatible with all 12V lead-acid batteries (flooded, gel, AGM, SLA, VRLA, maintenance-free) for boats, cars, RVs, powersports, campers, and deep cycle applications

Important Safety Reminder: To avoid any potential risks, never allow the positive and negative terminals of your battery to touch or connect. Although the likelihood of accidents is extremely low, it’s imperative to exercise caution during the installation to prevent any unintended short-circuiting.

POWOXI solar battery charger is suitable for maintain any rechargeable 12V Batteries.( lncluding Lithium-ion, LiFePO4, Gel,AGM, etc.)

You don’t need to disconnect. Our solar panel has overcharge protection circuitry built into the panel, prevent reverse charging.

Most cars can be charged with a cigarette lighter when the engine is turned off. When it is found that the cigarette lighter can not be used to recharge the battery. You can use alligator clips and cables to connect directly to the battery.

In full sunlight, the solar panel shows a red light. Connect the battery, and turn green. If there are no lights, check the polarity.

It is a trickle charger that keeps the voltage from dropping or recharging the battery, but it is not a fast charger and cannot charge a dead battery. Please use the AC charger to fully charge the battery before using the solar panel.
