The current output of most charging treasures is 5V~2A or 5V~ 1A, which is only suitable for ordinary computers connected with LED lamps or small desk lamps. Anything that meets the input power of the desk lamp can actually be charged.

A desk lamp generally refers to an electric lamp whose base is placed on a table. However, with the progress of science and technology, the appearance and shape of desk lamps are also developing constantly, and a magnetic desk lamp that can be adsorbed at any position has gradually emerged, which is small, exquisite and convenient to carry. The main function of desk lamp is lighting, which is convenient for reading, studying and working. The desk lamp has gone far beyond its own value and even become a work of art. ..
The principle of touching the desk lamp is that an electronic touch ic is installed inside, which forms a control loop with the electrode sheet at the touch of the desk lamp.
When the human body touches the sensing electrode, the touch signal is transmitted to the touch sensing end through the pulse signal generated by the pulsating direct current, and then the touch sensing end will send out a trigger pulse signal, thus controlling to turn on the light.
Touch it again, and the touch signal will be transmitted to the touch sensing terminal by the pulse signal generated by pulsating DC. At this time, the touch sensing terminal will stop sending out the trigger pulse signal, and when the AC current crosses zero, the light will naturally go out.
But sometimes it will light up automatically after power failure or voltage instability. If you touch paper or cloth, you can control it because it has excellent sensitivity to received signals.
