Mobile power has seized the market of smartphones and is now widely used with various portable electronic products, such as laptops, tablet PCs, smart phones, digital cameras, camcorders, portable DVD players, PDAs, MP3 players, MP4 players, GPS devices, thermal equipment, healthcare equipment, and more. These devices rely on batteries, and the limited battery capacity often cannot sustain their normal usage. When traveling or on the go, mobile power proves to be highly beneficial.

With the increasing popularity of mobile power, numerous companies have entered the market with their own mobile power solutions. Shenzhen East Conduction Technology has assisted numerous customers in successfully replicating mobile power supply PCBs and discovered various mixed mobile power programs, with designs for single USB, dual USB, and Apple phone compatibility.

Regardless of the specific solution, mobile power generally incorporates the following features: a single-chip charge control, boost output, and battery indicators. Most mobile power devices are lightweight and equipped with around six indicator lights. After pressing the standby key, the lights will flicker a few times before turning on, with LI indicating charging, L2 indicating strobe output, and L2I continuously on indicating full output. L3 to L6 are battery indicators. The output will automatically go into standby when no-load current is detected after connecting a load device.

A typical mobile power program has a USB input voltage of DC 5V and USB power output of DC 5V 1000MA. Shenzhen East Conduction Technology offers a cost-effective mobile power solution with the HT3982, an integrated charge management module that replaces the current charge management IC and MCU boost IC programs in the market. This single-chip module includes functions such as charging management, power detection and LED indicators, step-up capabilities, LED flashlight function, and standby mode.

Tailoring to customer demands, personalized mobile power PCBA production can be designed based on appearance and functionality requirements.
