Embodiment 1

[0013] Kind of like figure 1 The power bank with adjustable output voltage shown includes a housing 1 and a USB interface located on the housing 1, and also includes a knob 3 provided on the housing 1, and an LED indicator provided on the housing 1. 2; The power bank with adjustable output voltage is achieved by adjusting the output voltage through the rotary rheostat in series with the output voltage and adjusting the resistance connected in the circuit through the knob 3 (existing technology), which can be adjusted according to the rated input voltage of the electronic product The output voltage conforming to the rated input voltage of the electronic product is not only convenient, but also can avoid the damage to the electronic product caused by the non-conforming output voltage.

Embodiment 2

[0015] For the above-mentioned power bank with adjustable output voltage, the knob 3 is located on the front of the power bank, beside the USB interface, and the LED indicator 2 is located on the top of the casing 1. The casing 1 is also provided with a character 4 indicating the output voltage. The character 4 is located in front of the LED light 2. When the knob 3 is turned, the resistance connected in series in the output circuit will be increased or decreased, thereby reducing or increasing the voltage in the output circuit. The LED indicator 2 and the corresponding character 4 Can display the current output voltage.

Abstract

The invention belongs to the technical field of mobile power supplies, and particularly relates to a charging Po with adjustable output voltage. The charging Po comprises a shell and a USB interface on the shell. The charging Po further comprises a knob arranged on the shell, and LED indicating lamps arranged on the shell. According to the charging Po with adjustable output voltage, the output voltage can be adjusted, and the output voltage can be adjusted to an output voltage in accordance with the rated input voltage of an electronic product based on the rated input voltage of the electronic product. Operation is convenient, and damage of improper output voltage to electronic products is avoided.

Description

Technical field [0001] The invention belongs to the technical field of mobile power supplies, and specifically relates to a power bank with adjustable output voltage. Background technique [0002] With the rapid economic development, small electrical devices such as mobile phones and cameras that use 3V, 5V, and 12V have become an indispensable part of people. A power bank is a device that can directly power or charge the product through the DC power input interface of the electronic product. Generally, lithium batteries or dry batteries are used as the storage unit; the existing power bank generally does not have the output voltage adjustable function, which is greatly The range of power banks is limited, and only electronic products with matching voltages can be charged. Summary of the invention [0003] The purpose of the present invention is to overcome the problem that the voltage of the existing power bank cannot be adjusted. [0004] To this end, the present invention provi...
