Safety Instruction
Preparation Before Use
1.1 Read the User Manual
Carefully review the user manual provided with the device to understand the power station's interface functions, rated power, supported device types, and usage methods. Pay special attention to the rated power and output voltage of each interface to ensure compatibility with connected devices.
1.2 Device Inspection
Before use, inspect the power station and accessories to ensure they are intact, with no exposed wires or damaged interfaces. Confirm that all interfaces are dry and clean.
Device Compatibility and Precautions
2.1 Matching Power Specifications
Verify that your device's rated power matches the power station's output. Examples include:
- USB-C Interface: Suitable for small portable devices like smartphones and tablets (e.g., iPad).
- Car Charger Interface: Avoid connecting sensitive devices like radios.
- AC Socket: Designed for high-power devices like TVs or sound systems, but the power must be within the station's rated output.
2.2 Avoid Simultaneous Connection of High-Power and Sensitive Devices
Do not connect high-power devices (e.g., refrigerators, induction cookers) and sensitive equipment (e.g., TVs) at the same time to prevent voltage fluctuations that could damage the devices. Do not use the power station to power medical equipment and precision instruments.
Common Mistakes and How to Avoid Them
3.1 Using the Wrong Interface, Causing Device Damage
Error Example: Using the car charger port for powering voltage-sensitive devices (e.g., radios).
Precautionary Measures:
- Check the device's power requirements (wattage, voltage).
- Connect to the correct interface.
3.2 Damage Due to Instant Voltage Fluctuations
Error Example: Keeping sensitive devices connected while turning the power station on or off.
Precautionary Measures: Disconnect devices before powering the station on or off.
3.3 Overloading the Power Station
Error Example: Powering multiple high-power devices simultaneously, exceeding the station's power limit.
Solution: Check the station's rated power and plan device usage accordingly.
Usage Scenarios and Precautions
4.1 Charging via the car charger
- Do not charge devices via the car charger interface when the vehicle is starting or stopping to avoid voltage spikes.
- Ensure the device's power aligns with the station's output specifications when using the car charger interface.
4.2 Indoor Use
- For TVs, sound systems, and other devices in EPS mode, ensure the input source is grid power or a pure sine wave generator.
