About this item

  • Innovative MPPT Built-in Controller: Maximizes charging efficiency with up to 99% conversion. The 15W MPPT charger adjusts power based on sunlight intensity, ensuring superior performance even on cloudy days compared to non-MPPT chargers
  • Smart Maximum Power Point Tracking: POWOXI-MPPT optimizes energy extraction for changing conditions, ensuring efficient solar power harnessing by dynamically adjusting to the environment for maximum output
  • Comprehensive Battery Protection: MPPT controllers include a float/maintenance stage to prevent overcharging, extending battery life and improving energy efficiency. Compatible with various 12V batteries, including gel, AGM, SLA, VRLA, and lithium-ion
  • 3 LED Indicator Lights: The solar charger has three lights: blue for sunlight reception, red for charging, and green for a fully charged battery. The MPPT takes 2 seconds for calculation and LED status updates
  • Robust and Long-lasting Materials: Made with PC+ABS+Tempered glass, these solar panels withstand -40 to 137°C and are IP65 waterproof, enduring heavy rain, ABS+PC frames are stronger than flexible panels and won't damage car paint like aluminum frames
  • Voltage Detection Statement: The solar charger’s built-in MPPT controller adjusts voltage based on load, which is why tests may show readings below 14.2V. The MPPT controller optimizes the charging voltage to the most suitable level for the battery
  • Note: Unlike solar panels equipped with a PWM controller or without a controller, which have an open-circuit voltage of 18V-21V, the solar panel with a built-in MPPT controller has a voltage below 14.2V
  • 12-Month After-Sales Service: The quality of your premium solar battery charger is guaranteed by CE/ROHS certifications and comes with a free lifetime technical support! If you have any questions, please contact us. Your suggestion helps us improve

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.

  • An Maximum Power Point Tracking controller boosts solar panel efficiency by dynamically adjusting voltage and current. This ensures the system operates at its maximum power point, optimizing energy conversion efficiency under varying light conditions

  • The POWOXI solar battery charger is suitable for maintaining any rechargeable 12V batteries, including Lithium-ion, LiFePO4, Gel, AGM, etc.

  • No, you don't need to disconnect. Our solar panel is equipped with overcharge protection circuitry built into the panel, which prevents backward charging.

  • Yes, most cars can be charged with a cigarette lighter even when the engine is turned off. In cases where the cigarette lighter cannot be used for recharging, you can use alligator clips and cables to connect the solar panel directly to the battery.

  • 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.

Used this solar charger to maintain the charge on my generator battery. Important to face it South or SW to get enough sunlight. It replaced an AC powered trickle charger that was not working very well. Charging light was red in the morning, but by end of day was green, indicating a charged battery. Impressed !

Lost the plastic nuts which hold suction cup bolts on first use; they come off too easily. Replaced with metal nuts from HD, added locktite.Light scheme never really shows that full charge range has been achieved, though multimeter indicates this is true. But after a very long sit in a parking lot, vehicle fired right up, so it apparently did its job. Included additional connectors seem kinda cheap but serviceable.

Seems to do ok. Use it mostly for camping to maintain cellphone, other small battery powered devices. Use it to charge / maintain other batteries at home. 4 stars simply since I don't know how durable it will turn out to be.
