Power Bank Module Type-C and USB-A 5V 2A – High Efficiency Boost Converter

This compact and efficient power bank module is designed for lithium battery charging and discharging applications, featuring a Type-C input and USB-A output. It supports 2A output current and offers precise control over the charging voltage, including selectable charging voltages via solder pad adjustment (power-off operation required).

Features:

• Type-C input with high-accuracy charging voltage.
• User-adjustable charging voltage: 4.2V or 4.35V (power-off required to switch).
• High output current: up to 2A with 92.5% boost conversion efficiency.
• Boost output with line loss compensation (5V~5.15V).
• Low standby current: <30µA.
• Supports discharging while charging.
• Auto power-off when load current is continuously <50mA.
• Manual USB-A port soldering required; female connector included.

Functional Highlights:

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