Today, a customers asked whether our led table lamp products offer AC input? For this question, I want to introduce some current input knowledge of our table lamps.
Firstly, I would like to say, we have tow kinds of led table lamps. The one is supported with lithium battery，and charged with USB. The other one is without lithium battery, and charge with adaptor.
Then, some of our led table lamps are charge with AC, but all of the lamps was input with DC finally. DC: it consist with DC stabilized voltage power supply and DC constant current power supply, the output power supply or current does not change with the change of time. AC: the output voltage varies periodically over time. For, the table lamps work with small and stable voltage, it always input with DC.
However, why I said, “some of our led table lamps are charge with AC”. Because, this kinds of lamps is without lithium battery, and charge with adaptor, when it working, the adaptor gets electric current form AC hicky, and changes AC from DC.
