Relife XA1 Current Voltage Tester

Relife XA1 Current Voltage Tester

Relife XA1 Current and Voltage Multifunctional Tester is a compact yet highly advanced USB power measurement tool designed for technicians, repair engineers, cable testers, and electronics hobbyists who need precise, real-time monitoring of voltage, current, energy, and charging protocols. With its smart automatic identification system, intuitive IPS color display, and wide compatibility with USB Type-C devices, the XA1 stands out as one of the most reliable and feature-rich testers available in today’s mobile repair and electronics testing market.

Advanced Power Measurement for Modern Devices

Modern smartphones, fast chargers, laptops, and power banks use a variety of fast-charging technologies such as PD (Power Delivery), QC (Quick Charge), and SCP (Super Charge Protocol). Understanding these protocols and testing them accurately is essential, especially for repair shops and electronics technicians. The Relife XA1 automatically detects the charging protocol the moment you connect a device, making it a powerful diagnostic tool. It helps users verify whether the charger or cable supports true fast charging, or if the connected device is receiving the correct current and voltage under load.

Comprehensive Voltage and Current Monitoring

With professional-grade measurement accuracy and a wide working range, the XA1 gives you detailed insights into power delivery performance:

Voltage Range: 4V – 25V

Current Range: 0A – 5A

Voltage Resolution: 0.01V

Current Resolution: 0.01A

Accuracy: ±1%

This allows precise testing of chargers, power banks, Type-C cables, and virtually any USB-powered device. Whether you’re charging a smartphone, powering a laptop, or validating the output of a USB-C desktop charger, the Relife XA1 ensures you get accurate readings every time.

Automatic Recognition of Fast-Charging Protocols

One of the standout features of the Relife XA1 tester is its ability to automatically identify a wide range of charging protocols, including:

PD (Power Delivery)

QC 2.0 & QC 3.0

SCP (Super Charge Protocol)

AP 2.4A

DCP (Dedicated Charging Port)

This feature is extremely useful for repair centers, as it quickly reveals whether a device or charger is functioning properly and delivering the expected performance. It also helps users distinguish between genuine fast-charging accessories and low-quality or counterfeit products.

Bidirectional Current Measurement

The XA1 uses a specialized sensing chip that allows both forward and reverse current sampling. This means it can measure current flowing from charger to device, as well as device to charger, making it perfect for testing power banks during both charging and discharging cycles.

This bidirectional capability is especially beneficial for technicians who need to evaluate battery behavior, verify cable performance, and confirm that power banks deliver accurate output ratings.

High-Quality IPS Display

The tester features a bright, clear 160×80 DPI IPS color display, which shows all parameters in real time, including:

Voltage

Current

Power (W)

Capacity (Ah)

Energy (Wh)

Charging protocol

Real-time graphs and movement indicators

The interface is neatly designed, easy to read, and features a one-key screen flip function, allowing the user to rotate the display depending on the connection direction.

Capacity and Energy Tracking

In addition to real-time current and voltage measurement, the Relife XA1 can measure:

Total energy transferred (Wh)

Total battery capacity delivered or received (Ah)

This makes the XA1 incredibly useful for testing power banks to verify their true usable capacity, checking charger efficiency, or calculating actual battery performance during repair diagnostics.

Compact Design with Practical Features

Despite its powerful functionality, the XA1 remains extremely portable, lightweight, and convenient to use. Its compact form factor (67×62×12 mm, approx. 20.5g) allows technicians to carry it in their repair kit or pocket easily. The tester also includes:

Screen off button to avoid light pollution

Durable PCB structure

Heat-resistant connector build

Stable operation without overheating

Ideal for Repair Shops, Technicians & Hardware Testers

The Relife XA1 is widely used in:

Mobile phone repair centers

Computer and laptop service shops

Cable and charger testing labs

Power bank quality inspection

DIY electronics debugging

USB-C gadget development and testing

Its accuracy, versatility, and ease of use make it a go-to tool for diagnosing charging issues, detecting fake accessories, and validating real device performance.
