What are the functions and benefits of rechargeable desk lamps? | rechargeable lamp
1. The role of rechargeable table lamps
It can be used when there is no other external power supply, such as power failure.
Second, the benefits of rechargeable table lamps
It can be used for emergency use when the power is out and cannot be used for related learning and work, or it can be directly taken to an outdoor place where there is no power supply for operation.
Three, the precautions for the use of rechargeable table lamps
1. If the battery is discharged until the LED lamp is turned off and then recharged, the battery is already in an over-discharged state, and over-discharge will seriously affect the battery life;
2. Usually when the battery is discharged to about 80% of the nominal voltage of the battery, it is time to charge the battery. For example: a nominal 3.7V lithium battery needs to be charged when discharged to about 3V, and a nominal 6V lead-acid battery needs to be charged when discharged to about 4.8V;
3. The LED desk lamp is very power-saving. If the battery capacity is large and the continuous discharge ability is strong, it is not easy to detect the change in the brightness of the LED desk lamp during the entire lighting process. It is indeed difficult to judge when the discharge is over by visual inspection; the simplest The method uses a multimeter to detect the battery voltage to determine whether it should be charged.
