Description

Technical Field

[0001] This utility model relates to the field of mobile power supply equipment technology, specifically to a portable mobile power supply. Background Technology

[0002] With societal progress, more and more people enjoy camping or working in the wilderness. However, electricity is a major issue for outdoor living and working. Many digital portable entertainment and communication electronic products, such as mobile phones, laptops, tablets, digital cameras, digital camcorders, MP4 players, PDAs, portable GPS devices, and portable DVD players, become unusable after their batteries are depleted, causing considerable inconvenience. Portable power banks provide these portable electronic devices with more suitable, versatile, durable, safe, and systematic backup power, and have become an essential part of daily life.

[0003] However, existing portable power banks are more like large power banks, and their biggest drawback is the low energy density and small energy storage capacity of their batteries. To increase energy storage capacity, the portable power bank must be made larger, which inevitably increases its weight and reduces its portability. Furthermore, most current portable power banks only have a DC output port and a charging interface, making it difficult to meet the power needs of AC-powered devices such as computers and DVDs. Therefore, this utility model proposes a portable power bank to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a portable power bank. By using lithium iron phosphate batteries, which have high energy density, long battery life, and long service life, as the battery pack, the volume occupied by the battery pack inside the casing is significantly reduced compared to traditional lead-acid batteries, thus greatly reducing the overall size of the portable power bank. The outer perimeter of the casing is equipped with several AC output ports, several DC output ports, several USB ports, a cigarette lighter, a touch screen display, and a charging port. These multiple power output ports can meet the needs of various DC and AC power devices. Users can select and switch the appropriate power output port via the touch screen display according to their actual needs. The cigarette lighter function also expands the application range of the portable power bank. The touch screen display can also monitor the charging voltage, charging current, and remaining battery power, allowing users to understand the current working status of the portable power bank in real time. The overall structure is simple, economical, and practical.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a portable power bank, including a housing with a door at the opening. Inside the housing are a battery pack, an inverter, a USB circuit board, and a control circuit board. The outer periphery of the housing is provided with several AC output interfaces, several DC output interfaces, several USB ports, a cigarette lighter, a touch screen, and a charging interface. The AC output interfaces are electrically connected to the battery pack via the inverter. The DC output interfaces, cigarette lighter, and USB circuit board are all electrically connected to the battery pack. The inner ends of the USB ports are located on the USB circuit board. The touch screen is electrically connected to the battery pack via the control circuit board. The battery pack is a lithium iron phosphate battery.
