What Is the Realtek 8762 Chip?
Before diving into charging, let’s quickly touch on the Realtek RTL8762 series. It’s a low-power Bluetooth system-on-chip (Soc) used in many affordable smartwatches and wearable tech.
Key features include:
- Low energy Bluetooth 5.0

Charging Basics: What to Know First
Most Realtek 8762-powered devices are sold under brand names like:
- Y68, T500, or IWO smartwatches
- Generic fitness bands
- Unbranded Chinese smart devices
Charging methods vary slightly but usually fall into one of these types:
- Magnetic Pogo Pin Charger
- USB Plug-In Charger (integrated into the band)
- Clip-on Charger
Check which one your device uses before attempting to charge.
Step-by-Step Charging Instructions
Magnetic Charger (Most Common)
- Align the magnetic charger with the back of the device, where the metal contacts are located.
- Let the magnets snap into place, and ensure the pins align with the contacts.
- Plug the USB end into a 5v power source (laptop, power brick, or USB port).
- Charging should begin automatically. A battery icon or screen light may indicate this.
Tip: If it doesn’t start charging, clean the contact points gently with a dry cloth.
USB Built-In Charger (No Cable Required)
- Some bands require you to remove one strap to reveal a hidden USB plug.
- Gently slide or pull the watch strap off (usually from the top side).
- Look for the metal USB connector.
- Plug directly into any standard USB port (on a PC, adapter, or power bank).
- Watch the screen for a charging indicator.
Note: Make sure the pins are properly inserted. If inserted upside-down, it won’t charge.
Clip-On Charger
- Less common, but still used in some models.
- Open the clip and carefully position it around the device.
- Make sure the clip’s pins match the charging contacts on the watch.
- Plug the USB end into a charger or power outlet.
- Watch for vibration or a screen light to confirm that the device is charging.
How Long Does It Take to Charge?
Charging time depends on the device’s battery size, but on average:
- 1.5 to 2 hours for full charge
- Most devices have 90mAh–180mAh batteries
- Use only 5V/1A or 5V/2A chargers (avoid fast chargers)
Charging too fast can damage the battery or shorten its lifespan.
