POWOXI 12V Solar Car Battery Charger with MPPT — 15W Tricle Charger for Car, RV, Boat, Motorcycle

Overview

The POWOXI 12V Solar Car Battery Charger is a compact 15W solar panel with a built in MPPT controller designed to keep 12V batteries topped up during road trips, boating sessions, or camping adventures. Its thoughtful design emphasizes energy efficiency, reliability, and ease of use, so you can focus on where you’re headed next rather than worrying about battery levels.

Smart MPPT for higher efficiency

The integrated POWOXI MPPT controller continually searches for the best operating point and adapts to changing sun conditions. In practice, this means more energy harvested when the sun is strong and steadier performance on overcast days than some non MPPT chargers.

• Up to 99% conversion efficiency under ideal conditions
• Dynamic adjustments to light levels for maximum output

Battery protection you can trust

The charger includes a float or maintenance stage to prevent overcharging, helping to prolong battery life. It supports a range of 12V batteries including gel, AGM, SLA/VRLA, and lithium ion chemistries, offering flexibility for different setups.

• Float/maintenance stage to guard against overcharging
• Broad battery compatibility for automotive, marine, and power systems

Clear feedback at a glance

Three LED indicators provide quick status: blue for sunlight reception, red for charging, and green when the battery is fully charged. The MPPT controller completes calculations in about two seconds for timely updates.

Rugged, weather ready design

Constructed with PC plus ABS and tempered glass, the panel withstands harsh temperatures from -40 to 137 C and carries IP65 waterproofing. A solid frame helps protect your vehicle’s finish while staying lightweight.

Voltage behavior and safety details

Voltage tests may show below 14V during load changes, but once connected to a battery, open circuit charging stays under 21V, helping to reduce overvoltage risk.

What’s in the box and support

Every order includes a fabric storage bag for easy transport and storage. The charger is CE/ROHS certified and backed by 12-month after sales service, plus free lifetime technical support for questions and guidance.

Real world benefits and use cases

Ideal for daily commuters with long drives, weekend campers, and owners with trailers or boats. The combination of compact size, robust materials, and intelligent control makes it a practical tool for maintaining 12V battery health in sunny and cloudy conditions alike.
