## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0849:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR0849:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged.

## 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.
