Power Adapter Operating Temperature

　　Power adapters typically use a dark plastic casing for heat dissipation and temperature control. Internal components also have their own operating temperatures. Therefore, power adapters have an ambient operating temperature, which is either room temperature or external temperature. Most lithium battery chargers on the market have an operating temperature requirement between -10℃ and 50℃. Specialized power adapters are required for operation at certain temperatures. Regularly monitor room temperature; stop using the charger if it reaches or falls below the lithium battery charger's operating temperature.

　　Power Adapter Operating Humidity

　　Electronic products, including power adapters, require specific humidity levels for optimal operation. The ideal humidity for an adapter is generally between 10% and 90%. If the humidity is below 10% (too dry), the adapter may malfunction or burn out due to electrostatic interference. If the humidity is above 90%, the adapter's creepage distance can extend to the outside environment, compromising the safety of the electronic product and posing a threat to people and property.

　　Power Adapter Operating Atmospheric Pressure

　　Altitude affects atmospheric pressure, directly impacting the operation of power adapters. Just like squeezing or pressing with your hand or an object, excessively low air pressure can make lithium battery chargers fragile, prone to breakdown, arcing, corona discharge, and other phenomena, affecting the adapter's lifespan and the use of electronic products.

　　In addition to the above-mentioned working environment requirements, salt spray, mold, dust, and direct sunlight can also cause power adapter malfunctions. Users should avoid such environments in their daily work and life. If exposed to these conditions, the power adapter should be stopped immediately to ensure safe operation and extend its lifespan.
