Precautions for using portable power supplies

1. Pre use inspection:
-Battery level confirmation: Check the battery level display of the portable power supply before use. If the battery level is low, charge it promptly to avoid affecting the normal operation of the device due to battery depletion during use. For portable power supplies that have not been used for a long time, it is also necessary to check the battery level and charge them according to the situation before use.
-Load power matching: Verify the power of the connected devices to ensure that they do not exceed the rated power of the portable power source. If the load power is too high, it may cause problems such as power overheating, battery voltage drop, automatic shutdown, and even damage to the power supply.
-Equipment condition inspection: Check the appearance of the power supply for damage, deformation, cracking, etc., as well as whether the interface is loose, poorly connected, etc. If these problems exist, they may affect the normal use of the power supply or pose safety hazards, and should be repaired or replaced in a timely manner.
2. In terms of usage environment:
-Suitable temperature: Avoid prolonged use of portable power sources in high or low temperature environments. High temperature can cause the temperature of the battery to rise, which may lead to dangers such as battery fire and explosion, and also reduce the battery life; In low temperature environments, the performance of the power supply may be severely reduced and may not meet normal usage requirements. Generally speaking, the suitable operating temperature for portable power supplies is between 0 ℃ and 40 ℃.
-Keep dry: It is strictly prohibited to use in damp or wet environments, and avoid letting the power supply come into contact with water or other liquids. Moisture may enter the interior of the power supply, causing faults such as short circuits and damage to the circuit board.
-Keep away from sources of fire and corrosive substances: Portable power supplies should be kept away from sources of fire and heat, and avoid use in flammable, explosive, and corrosive gas environments such as gasoline and gas to prevent accidents.
3. Charging precautions:
-Use original charger: It is recommended to use the charger that comes with the power supply for charging to ensure safe and efficient charging. If using other chargers, ensure that their parameters match the power supply.
-Safe charging environment: When charging, choose a well ventilated, dry, and suitable temperature environment. Avoid charging near high temperatures, humidity, or flammable materials, and also prevent the charger and power supply from being squeezed, bumped, etc.
-Avoid overcharging: If the power supply has overcharge protection function, it will automatically stop charging after charging is completed; But if this function is not available, the charger should be unplugged promptly after charging is complete to avoid overcharging causing damage to the battery.
4. Operation during use:
-Avoid external damage: During use, avoid violent throwing, impact, friction, or squeezing of the power supply to prevent damage to components such as the power supply casing, internal circuit board, and battery, which may cause safety accidents.
-Reduce use while charging: Although some portable power sources support use while charging, this method increases the burden on the battery and affects its lifespan. Therefore, unless necessary, try to avoid use while charging.
-Prevent overload protection triggering: When the power of the connected device approaches or exceeds the rated power of the power supply, the overload protection function may be triggered, causing the power supply to cut off the output. At this point, the power switch should be turned off, the overloaded load device should be unplugged, and then the power should be restarted.
5. Requirements for long-term storage:
-Regular charging and discharging: If the portable power supply is not used for a long time, it should be fully charged and discharged at regular intervals (usually 3-6 months) to maintain battery activity and extend the service life of the power supply.
-Appropriate battery storage: When stored for a long time, the battery level of the power supply should not be too high or too low, and it is more appropriate to maintain a battery level of around 50%.
-Good storage environment: Store the power supply in a dry, ventilated, and cool place, away from direct sunlight and high temperatures, and keep away from sources of fire, heat, and corrosive substances.
