Description

UNIVERSAL AND PORTABLE POWER BANK

TECHNICAL FIELD

[0001] The present disclosure relates to a universal and portable power bank. In particular, it relates to a power bank having self-adjusting side clips for holding electronic devices of different sizes, and further comprises a flexible single USB connector for supplying input power to the electronic device from a single input USB connector. The present disclosure further relates to a universal and portable power bank that is self-adjusting to hold various sizes of electronic devices, and further comprises a flexible single USB connector for supplying input power to the electronic device from a single input USB connector.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] A wide range of portable electronic devices are currently available in the market, such as smartphones, mobile phones, tablet PCs, computers, laptops, wearable devices, IoT devices, audio/video/text/book players, and many more. Such electronic devices are configured to support fast-response, and for this purpose, advanced processors and many sensing elements are employed while designing the devices. These advanced processors and sensing elements consume a high amount of power during operations, requiring the portable electronic devices to be supplied with supplementary power from time to time. When user carries electronics products outside, additional power source is needed from time to time for fulfilling user's requirements of power, and therefore additional portable power sources are used and have recently become popular.

[0004] As each company comes with different power banks based on devices that need to be powered, such power banks tend to have different configurations such as size, power storage capacity, slots, that are suited for the respective device. These available devices also have another common major problem, wherein if we observe existing portable power sources/devices, the power sources form a separate unit and transfer power to respective electronic devices through a charging cable, which is only suitable when the devices are stationary or when user keeps the devices on a side only for charging. On the other hand, when a user wishes to hold an electronic device (such as smart phone) along with the power bank, it causes inconvenience to the user as both the device as well as the power bank/source are separate physical units, requiring the user to manage and firmly grip both the device carefully.

[0005] US 8541985 Bl discloses a multi-functional portable power bank where the power bank is a separate unit such that when a user wishes to hold the power bank with an electronic device, it causes inconvenience because the proposed power bank cannot be attached with electronic device.

[0006] There is therefore a need for an advancement in construction of a power bank in such a way that that power bank itself firmly holds the electronics device, requiring the user to only hold the power bank or the electronic device when both are connected via cable for fulfilling additional power requirements.

[0007] In addition to the above, it is to be noted that there are mainly three types of input charging connectors that are currently available for charging electronics devices, one being an Android™ type input USB charging port, another being Apple™/IOS type charging port, and yet another being type "C" charging connector port. A major problem of available power banks is that for charging of a device having varying input charging connectors like iOS, Android, or type "C", separate charging cables are required, which creates a problem to user for managing and handling these cables.

[0008] US20150035472 Al discloses a reel type power bank where the output USB that is fitted in the power bank is only of one type (iOS, type C, or Android connector), and therefore power bank configured under this US patent application can only work for those devices that have female connectors similar to the power bank.

[0009] There is therefore a need for an improved universal power bank that can resolve above mentioned problems by providing a universal cable that can be used for all types of input charging connectors.

[0010] Yet another problem with existing electronic devices is that the orientation and position of the female input charging port in the electronic devices varies with design, size, and shape. For charging these kind of electronic devices using power bank, a user needs a longer cable, thus causing inconvenience to the user for handling and managing longer charging cables.

[0011] There is therefore a need for a portable and universal power bank that can resolve the above-mentioned problems by providing a flexible power bank that accommodates a variety of electronics devices having variation in shape and size, and a provide comfort and convenience to user.
