Introduction
This manual provides instructions for the safe and effective use of your Lamshaw Magnetic Smart Watch Charger, specifically designed for the Joautrial ZW47 Smart Watch (2.02 Inches). This charger offers a convenient and secure method for powering your device, incorporating essential safety features to protect your smartwatch during charging.
The charger is built with an integrated short-circuit protection IC to prevent overvoltage and overcurrent. In the event of a short-circuit, the protection IC automatically cuts off the circuit. This safety mechanism also functions if the charger remains plugged in after your device is fully charged.
Product Overview


The Lamshaw Magnetic Smart Watch Charger is a compact and portable USB charging cable. It features a magnetic charging interface designed for easy and secure connection to your smartwatch. The cable is constructed with a flexible PVC outer layer and pure copper probes for efficient and stable power delivery.
Setup and Charging
