Yes, all Purmar products are compatible with 12V car cigarette lighter sockets.
Charging speed: Car chargers typically have a power output of 120–200W; a 500Wh power bank will take approximately 3–5 hours to fully charge.
⚠️Precautions: The cigarette lighter may lose power when the vehicle is turned off. It is recommended to start the vehicle before charging to avoid draining the car battery.
The main factors are:
Sunlight Conditions:Direct sunlight > diffused light. Charging efficiency can drop by more than 50% on cloudy days/under trees.
Installation Angle: The solar panel maintains a 30°–45° angle with the sun for optimal charging efficiency. Regular angle adjustment is recommended.
Obstructions:Dust, leaves, and shadows significantly reduce charging efficiency. Timely cleaning is necessary.
Temperature Effects: High temperatures (>40°C) trigger battery protection, reducing charging power.
Solar panels are sensitive to sunlight. Even slight obstructions can affect their power generation efficiency. Solar panels must not be partially shaded, especially for extended periods. Otherwise, the current path may be interrupted, and the solar panels could be partially damaged. Solar panels must be exposed to ample sunlight to avoid shading.
