MakerHawk USB Multimeter – USB Voltmeter & Ammeter, PD/QC Tester, 1.54-inch LCD

Overview

The MakerHawk USB Multimeter is a compact inline tester designed to help you observe charging performance across USB and Type-C connections. It features two-way insertion detection, a bright 1.54-inch LCD with a clear 240x240 resolution, and a user friendly layout with four operation buttons. Built with gold plated USB contacts and a protective coating, the device is designed for dependable readings in everyday setups—from home chargers to car adapters.

What it measures and supports

This handheld tester works with a wide range of USB and Type-C configurations. It can read voltage, current, and estimated power, while accommodating a variety of charging standards. The tool supports full digital protocol compatibility with PD and QC families, including PD 2.0/3.0/4.0 and QC 2.0/3.0/4.0, plus MTK and other protocols. It also accommodates USB2.0 connections up to 500 Mbps and USB-A with USB3.0 capabilities, enabling fast, broad compatibility across chargers, cables, and devices.

• Two-way insertion detection and a high-contrast LCD simplify orientation and readability during use.
• Multiple interfaces and protocol support help you verify performance across Type-C and USB connectors.

Alerts and visual cues

The built in reminder functions make it easier to spot potential issues before they become problems. Temperature alerts flash when readings exceed 45 C; voltage alerts flash when values fall outside 3.8 to 30 V; and current alerts blink if the current rises above 3 A. These cues can help you monitor charging behavior in real time without guesswork.

• Temperature alarms highlight overheating risk in busy charging setups.
• Voltage and current alarms provide quick, actionable feedback during testing.

Display, orientation, and ease of use

The 1.54-inch LCD is designed for quick, legible readings even in tight spaces. The display can rotate a full 360 degrees to match your viewing angle, and a simple horizontal menu lets you rotate the screen as needed. A sturdy design with gold plated contacts helps keep readings stable across daily tasks, from quick field checks to desk top measurements.

Real-world scenarios

Use this meter to evaluate USB-C PD chargers, verify QC outputs, compare power delivery across adapters, inspect battery packs, test car chargers, or assess the performance of long USB-C cables. Whether you are tinkering at a workbench or checking devices on the go, the tool aims to offer clear, actionable data without requiring specialized equipment.

Notes and support

Note that PD power is not supplied by default if no PD device is connected. When testing Type-C PD, you may need to orient the connector correctly or use the built in Type-C interface to complete the connection. MakerHawk provides responsive after-sales support; you can reach the team via the MakerHawk-US contact channel for assistance or guidance.
