Quick guide from the manual
The Technaxx 21W Solar Charging Case TX-207 is a portable, foldable solar charger designed for outdoor use. To achieve the best performance, place the panel in direct sunlight at a 90-degree angle. Avoid shaded areas such as trees or walls, as these significantly reduce power output. The device features two USB-A ports for charging smartphones and power banks.
Product Overview
The unit consists of a foldable solar panel array with a built-in pocket containing the USB output ports. It is constructed with a PET fabric cover and includes mounting tabs for securing the panel to tents or other structures using cords.
Setup and Installation
- Positioning: Place the solar panel in a bright, sunny location. A southern exposure is generally preferable.
- Angle: For maximum efficiency, ensure the sun hits the panel at a 90-degree angle.
- Mounting: Use the integrated mounting tabs to secure the panel with cords or attach it to tent rods if necessary.
Usage
Unfold the solar panel completely and expose it to direct sunlight. Connect your devices (smartphones, power banks) to the USB-A ports located in the pocket. Note that the maximum current of 3.5A is shared between the two ports when both are in use.
Safety Precautions
- Do not immerse the product in water or other liquids.
- Keep the device away from children.
- Do not leave the connected devices in direct sunlight while charging, as this may cause overheating.
- Never connect the solar panel directly to house power.
- Ensure all plugs are kept dry; do not use in wet environments.
- Do not modify the solar panel or attempt to repair it yourself.
Cleaning and Maintenance
Always disconnect all cables and cover the solar panel before cleaning to avoid electric shock. Clean the equipment regularly with a moist cloth. Do not use cleaning agents or solvents. Ensure that no water enters the plugs or the electrical components.
