Comment:

• In low sunlight, the output current may be significantly lower – use with a charging module is recommended.
• The USB-C connector is for voltage transfer only – it is not intended for communication (no PD or USB data connection).
• For direct charging of Li-Ion batteries, we recommend using with a TP4056 module or similar that has input protection.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
