Power Bank Module Type C and USB-A 5V 2A

This compact and efficient power bank module is designed for charging and discharging applications of lithium batteries. It features a Type-C input and a USB-A output. It supports a 2A output current and provides precise control over the charging voltage, including the ability to select the charging voltage by adjusting the soldering pad (requires shutdown).

Features:

• Type-C input with high-precision charging voltage.
• User-adjustable charging voltage: 4.2V or 4.35V (shutdown required for switching).
• High output current: Up to 2A with an enhanced conversion efficiency of 92.5%.
• Output boost with line loss compensation (5V~5.15V).
• Low standby current: <30µA.
• Supports discharging while charging.
• Automatic shutdown when the load current is continuously <50mA.
• Manual soldering of USB-A port required; female connector included.

Key Functional Features:

• Power display and output control via an external button (K point to GND).
• Charging process ends when the current drops to 100mA after reaching the final voltage.
• Charging process resumes when the battery voltage drops below 4.1V.
• Pre-charging mode at <2.8V with 180mA current.
• Output voltage ripple: 100mV.

Specifications:
