Description

rechargeable desk lamp

technical field

The utility model relates to the field of household appliances, in particular to a charging desk lamp.

Background technique

Desk lamp is the necessary household appliance of people's daily life. With the development of society, products with a single function are gradually being eliminated and replaced by products with multiple functions. For example, there is a desk lamp on the market that integrates multiple USB interfaces, which can be used as an interface between electronic products and computers, and solves the problem of few data transmission ports of the computer itself. In addition, there is also a rechargeable desk lamp that can charge electronic products through a USB interface. This desk lamp uses a conventional USB interface, the current output value is 5V/500mA, although it can charge most electronic products, but for products with a large charging current demand, such as tablet computers and mobile phones, such as Apple's IPAD and IPHONE require charging currents of 2.1A and 1A respectively, and conventional USB interface charging cannot meet the requirements. In addition, general mobile phone manufacturers will set a fast charging voltage demand value in the product. When the charging voltage meets the set voltage value, fast charging can be performed. This voltage value is the fast charging voltage value. For example, the fast charging voltage of IPHONE is a specific signal, which is a voltage value less than 5V. Using a general adapter, because the output voltage is 5V, the specific fast charging function of IPHONE cannot be activated, and the charging time is longer. If you use the fast charging voltage to charge, you can shorten the charging time. Users often dislike the charging time for too long, and choose to use the adapter provided by the manufacturer to charge, which will take up more power ports and space, and is inconvenient to use and place.
