Abstract

The invention relates to a novel portable USB (universal serial bus) concentrator. Mobile power supplies and USB concentrators are matched products necessary for the daily use of mobile devices such as mobile phones, and conventional mobile power supplies and USB concentrators are independent products, and are required to be bought, stored and used respectively, so that great inconvenience is caused. The novel portable USB concentrator comprises a shell, wherein an uplink USB interface and downlink USB interfaces are arranged in the shell; a HUB and power management chip, a discharge management chip, downlink USB interface discharge management chips, a boosting chip, a charging chip and an AC-DC (alternating current-direct current) converter and safety plug are arranged in the shell. The novel portable USB concentrator is a product combining a mobile power supply and a USB concentrator, and the AC-DC converter and safety plug in the concentrator can be used for simultaneously providing power for a plurality of mobile devices, so that convenient and rapid experiences are provided for users, and the shortcoming of being undiversified in function of the two products, namely the mobile power supply and the USB concentrator, is overcome.
