Why it's a great deal

  • High Efficiency Conversion: Our solar panels use monocrystalline cells. Monocrystalline solar cells have a relatively high photoelectric conversion efficiency, which can reach approximately 20.25% under standard test conditions. This means they can convert solar energy into electrical energy more efficiently. Monocrystalline silicon solar trickle chargers can generate more power for charging under the same light conditions.

  • Battery Saver: Our solar panel is designed to charge and maintain 12V rechargeable batteries. Trickle charging is a slow charging method. When the battery being charged is low, the charger initially charges quickly with a high current. When the battery is nearly full, it automatically switches to trickle charging mode. At this point, the charger charges the battery with a small and stable current to compensate for the power loss caused by the battery's self-discharge, keep the battery fully charged, and prevent damage from overcharging.

  • Dual-Stage Smart Charging (14.4V/13.6V) - Built-in controller delivers 14.4V bulk charge → 13.6V float maintenance. Automatically protects against over-voltage with chip protection circuit. Compatible with 12V lead-acid batteries.

  • Wide Compatibility: Our 12V Solar Rickle charger is equipped with interfaces for O-ring, alligator clip, cigarette lighter, and OBDII to meet the charging needs of your various battery-powered devices. Use it to charge and maintain rarely used vehicles, boats, outdoor electronics, lawnmowers, and more. Ensure your devices always start and protect batteries from long-term discharge. It's also suitable for gate openers, water pumps, weather systems, cameras, etc. Compatible with most batteries, including sealed lead-acid, lithium, LiFePO4, GEL, mains, flood, and more.

  • Safe Charging Mode: The solar panel includes a built-in controller that prevents overcharging. The controller automatically stops charging when the battery is fully charged and resumes charging when the voltage drops. Our solar panel system will not discharge your battery.

  • Complete Car Charging Kit - Includes: 20W solar panel, SAE cable, SAE-to-OBDII adapter, SAE-to-cigarette plug, SAE-to-alligator clips, SAE-to-terminal, 4 suction cups, 4 carabiners. 24hr support response guaranteed.

★★★★★Verified Purchase

Highly recommend the FlexSolar

Of all the vehicle tools I've owned over the years, the FlexSolar is easily the best. The complete car charging kit - includes works flawlessly — it's the first thing I mention when friends ask about it. It arrived quickly, was simple to set up, and at roughly $36 it's outstanding value for money. For anyone asking which vehicle tools to buy, I recommend the FlexSolar without hesitation.

The FlexSolar does what it's supposed to do. The wide compatibility is decent, though I expected a bit more polish at this price.
