Problems solved by technology

Since the power consumed by the laptop when it is turned on is much greater than the power required to charge mobile phones and other devices, it may not be possible to turn on the laptop when the remaining power of the battery itself is limited
Even if the laptop can be turned on, it will consume precious power and make it impossible to charge mobile phones and other devices normally

Abstract

A battery mounted on a first electronic device is used for providing power to the first electronic device. The battery comprises a casing and an electrical core combination accommodated in the casing. The battery is characterized in that: the battery is provided with a USB interface and a power supply interface, the USB interface is electrically connected with the electrical core combination to take power from the electrical core combination, the USB interface can be connected with a second electronic device to render the electrical core combination to charge the second electronic device, the power supply interface is electrically connected with the electrical core combination, and the power supply interface is used for connecting an external power supply to charge the electrical core combination. Compared with the prior art, the battery of the invention not only provides power to the first electronic device, but because the USB interface is disposed on the battery and directly powered by the electrical core combination, the battery can charge the second electronic device through the USB interface without starting the first electronic device, thereby saving electric quantity of the battery.

Description

technical field [0001] The invention relates to a battery, in particular to a battery that can be used to charge external equipment. Background technique [0002] Batteries are an integral part of mobile electronic devices such as laptop computers. Taking the battery of a notebook computer as an example, it can not only supply power to the notebook computer itself, but also charge other electronic devices such as mobile phones through the USB interface of the notebook computer. However, when using the USB port for charging, the notebook computer needs to be turned on. Since the power consumed by the laptop when it is turned on is much greater than the power required to charge mobile phones and other devices, it may not be possible to turn on the laptop when the remaining power of the battery itself is limited. Even if the laptop can be turned on, it will consume precious power and make it impossible to charge mobile phones and other devices normally. Contents of the inve...
