## Description

#### Introduction

This 2 USB buck fast-charging module integrates the common 5V charging recognition function, which is compatible with 99% of the mobile phones on the market. Compared with products without charging recognition function, this module can save a lot charging time by triggering the peak current via fast charging protocol. It features 6~32V input and 3~12V output(default 5V). The voltage can be changed through fast-charging decoy. Multiple fast-charging protocols are supported and the 2 channels work independently.

With steady output, this Fast Charge Module is able to work for a long time without voltage shift. It can be suitable for projects like mobile phone fast charging, Car charging retrofit, solar charger, DIY power source, etc.
