Innovative MPPT Built-in Controller
One of the standout features of this solar charger is its innovative Maximum Power Point Tracking (MPPT) controller. The MPPT technology plays a crucial role in maximizing charging efficiency by converting up to 99% of the sunlight into usable energy. Unlike traditional chargers, this one adjusts the power output in consonance with the sunlight intensity, which means even on cloudy days, it outperforms non-MPPT chargers.
Smart Maximum Power Point Tracking
This charger is equipped with POWOXI-MPPT, which is designed to optimize energy extraction under changing environmental conditions. What’s impressive is its dynamic adjustment capability, ensuring the uppermost output despite fluctuating sunlight. This smart tracking ensures you’re not just relying on good weather for effective solar charging.

Comprehensive Battery Protection
Float and Maintenance Stage
Nobody wants to deal with a battery that’s been overcharged. Thankfully, this charger includes a float/maintenance stage that fends off overcharging. It’s an effective solution to extend the overall life of your battery and enhance energy efficiency, making it compatible with various 12V batteries such as gel, AGM, SLA, VRLA, and lithium-ion.
3 LED Indicator Lights
Indicator lights on the charger provide a straightforward way to understand its status. The blue light indicates sunlight reception, while the red light shows that charging is occurring. When your battery is fully charged, the green light lights up. It’s worth noting that the MPPT function takes around two seconds for calculation and updating the LED status.

Robust and Long-lasting Materials
Made with a combination of PC, ABS, and tempered glass, the solar panels of this charger are impressively durable. They can withstand extreme temperatures ranging from -40 to 137°C. Additionally, the waterproof rating of IP65 ensures that it can endure even the heaviest of rainfalls. These materials ensure the functionality and longevity of the solar charger, unlike the weaker flexible panels that potentially damage car paint with their aluminum frames.
Voltage Detection for Optimized Charging
Smart Voltage Adjustment
One fascinating feature is its built-in MPPT controller that adjusts voltage based on the load. When performing tests, you might notice readings below 14.2V. But don’t worry, this is because the MPPT controller is optimizing the charging voltage to the most suitable level for your battery, rather than maintaining a high open-circuit voltage like other panels.
MPPT vs. PWM
| Features \ | MPPT | PWM |
|---|---|---|
| Voltage | Below 14.2V optimized | 18V-21V open-circuit |
| Efficiency | Up to 99% efficient | Less efficient |
| Performance | Adjusts to sunlight | Static, battery-dependent |
Unlike PWM-controlled solar panels, which need a higher open-circuit voltage, the MPPT controller’s output adapts perfectly for efficient charging. This adaptation is key to properly maintaining battery charge without the risk of overcharging.
12-Month After-Sales Service and Lifetime Support
POWOXI stands behind the quality of their solar charger with a 12-month after-sales service. The product is certified by CE/ROHS, ensuring compliance and safety. In addition, you receive lifetime technical support, so if questions arise or issues occur, customer assistance is a call away. They encourage feedback, as your suggestions contribute to continuous product improvement.
Safeguarding and sustaining your vehicle’s battery power doesn’t have to be burdensome, especially with a reliable tool like the POWOXI Upgraded MPPT 15W Solar Car Battery Charger & Maintainer. It’s designed to adjust to your environment, protect your battery, and offer a long-term, renewable solution.
