Diagnose power delivery and verify fast charging standards. Featuring a 16-bit ADC and bi-directional ports, it accurately monitors voltage curves and current flow up to 24V and 6.5A.

## Pricing

- **Price:** $28.10 (inc GST) — $25.55 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 300 more in 8–25 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10557:1` (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/CE10557:1.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. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

A high-precision USB tester designed to monitor voltage, current, and power across both USB-A and USB-C interfaces. It serves as a comprehensive diagnostic tool for evaluating the performance of chargers, power banks, and cables, utilising a 16-bit ADC (analog-to-digital converter) to deliver great measurement accuracy on your workbench.

For makers and technicians, the "black box" nature of modern fast charging can be frustrating; it is often unclear why a device isn't charging at full speed or if a power supply is delivering stable voltage. The FNAC-28 solves this by visualising real-time power data and automatically detecting supported fast-charge protocols. This allows you to instantly verify if a generic charging brick is truthful about its specifications or identify high-resistance cables that are bottling your power delivery.

Engineered for versatility, the unit features a crisp 1.06-inch colour TFT display and bi-directional ports, eliminating the need for complex adapter setups. With its ability to measure up to 24V and 6.5A, coupled with offline data storage for capacity checking, the FNAC-28 is a reliable, pocket-sized addition to any electronics toolkit needing to validate power delivery standards.

### Features

- **Diagnose Charging Issues Instantly:** Visualise voltage curves and current draw in real-time to identify unstable power supplies or faulty connections before they damage sensitive electronics.
- **Verify Fast Charge Protocols:** Automatically detect and trigger protocols including QC2.0/3.0, Huawei FCP/SCP, Samsung AFC, and VOOC/WARP to ensure your chargers are delivering the speeds promised on the box.
- **Universal Connectivity:** Test a wide variety of devices without adapters thanks to the integrated USB-A and USB-C male and female ports, supporting bi-directional current flow.
- **High-Resolution Measurement:** Rely on precise data for delicate repairs with the internal 16-bit ADC, offering 0.00001V and 0.00001A resolution capabilities.
- **Cable Resistance Testing:** Determine the quality of your USB cables using the differential pressure method to weed out cheap leads that cause voltage drops.
- **Human-Centric Interface:** View data comfortably from any angle with a display that supports four-way rotation and flip-screen functionality.
