Mini solar charger for DIY projects

This compact polysilicon panel is sold as a new internal power cable accessory for hobbyists building small outdoor charging experiments. It provides a portable photovoltaic surface intended to trickle-charge a mobile phone or similar low-power device in direct sunlight.

Output limited by panel size and light conditions

The module has no built-in regulator or battery, so voltage and current vary with sun angle, cloud cover and temperature. It cannot deliver stable USB power on its own and is unsuitable for devices that require a steady 5 V supply or for charging in shade or indoors.

Questions about this item

What voltage or wattage version of this solar panel should I choose for charging a phone?

The panel is a compact polysilicon module intended for DIY solar charger builds; select the version whose open-circuit voltage matches your charge controller or regulator requirements.

How much usable power will this panel deliver to a phone in real sunlight?

Under direct sun the module produces its rated voltage and current, but actual phone charging speed depends on the regulator efficiency, cable loss and the phone's own charge acceptance.
