H913-A Dual USB Power Bank Charging Module with LED Display

Description

Build or repair high-performance portable power banks with the feature-rich H913-A Dual USB Power Bank Charging Module. This premium electronic board acts as a complete charge and discharge management solution for 3.7V lithium-ion or LiPo batteries (such as 18650 cells wired in parallel). Equipped with dual USB output ports, it allows you to charge two devices simultaneously, dynamically distributing power between a 1A and a 2.1A line. The standout feature is its integrated clear LED digital display, which provides real-time readout of battery capacity percentage and active input/output states. For maximum safety, the module includes built-in protection against overcharging, over discharging, and short circuits. You can easily connect this module to your favorite microcontroller platform.

Features

• Dual USB Charging Outputs: Dual output ports allow you to power multiple external devices at the same time with a combined maximum output of 2.1A.

• Integrated LED Digital Display: High-visibility display panel gives precise real-time tracking of the internal battery capacity from 0% to 100%.

• Smart Multi-Port Inputs: Features dual charging inputs (Type-C and Micro USB) to give you flexible options using common charging cables.

• Comprehensive Protection IC: Built-in safeguards defend your custom battery packs from overcharging, over-discharging, and overcurrent scenarios.

• Intelligent Auto-Sleep Mode: Automatically powers down the display and output circuits when no load is detected to preserve internal battery reserves.
