Important Safety Information
To reduce the risk of electric shock, fire, or injury, always follow basic safety precautions when using electrical products. This includes, but is not limited to, the following:
- Do not exceed the electrical ratings of the power strip (2500W, 10A).
- Do not use in wet environments or near water.
- Do not disassemble or modify the device.
- Keep out of reach of children.
- Ensure the power cord is fully inserted into a grounded wall outlet.
- Avoid running the power cord under carpets or in areas where it can be damaged.
- If the surge protector is damaged, discontinue use immediately.
This surge protector includes overload protection. In the event of an overload, the power will automatically cut off to protect connected devices. If this occurs, reduce the load by unplugging some devices and then reset the main switch.

Operating Instructions
Using AC Outlets:
The power tower features 12 AC outlets distributed across its sides. Each side (group of 3 outlets) is controlled by an independent red ON/OFF switch located above the outlets. This allows you to power on or off specific groups of devices without affecting others.
- Plug your AC devices into the desired outlets.
- Press the red switch above the corresponding group of outlets to turn them ON or OFF.

Using USB Ports:
The power tower includes 3 USB-A ports and 1 USB-C port for charging mobile devices. These ports are always active when the main power switch is ON.
- Connect your USB charging cables to the appropriate USB-A or USB-C ports.
- Plug your mobile devices into the other end of the cables.
- The USB ports will automatically detect and deliver optimal charging current up to their maximum ratings.

Main Power Switch and Overload Protection:
A main red switch, often labeled "RESET" or "ON/OFF", is located at the base of the unit. This switch controls the entire power strip, including all AC outlets and USB ports. It also functions as an overload protector.
- To power on the entire unit, ensure this switch is pressed to the "ON" position.
- If the power strip experiences an overload, this switch will automatically trip to the "OFF" position, cutting power to all connected devices.
- To reset after an overload, unplug some devices to reduce the load, then press the main switch back to "ON".

- Storage: When not in use for extended periods, unplug the power strip and store it in a cool, dry place.
