  • Universal Compatibility: Specifically designed for smartwatches using "Veryfit" or "Da Fit" apps with a 2.54mm charging contact pin spacing. Users should measure their watch's pin spacing before purchase.
  • Fast Charging: Supports efficient charging via standard USB power sources such as PCs, laptops, and wall adapters, ensuring a quick and stable charging experience.
  • Secure Circuit Protection: Integrated Voltage Regulator (PTC) protects your smartwatch from overcurrent damage, extending its lifespan.
  • Portable Design: Compact and lightweight, making it ideal for travel, office, gym, or as a convenient spare charger.

2. Setup Instructions

2.1 Verifying Compatibility

Before using the charger, it is crucial to verify its compatibility with your smartwatch. This charger is designed for smartwatches that utilize the "Veryfit" or "Da Fit" applications and have a 2.54mm pin spacing between the two charging contacts.

  1. Measure Pin Spacing: Carefully measure the distance between the centers of the two charging pins on the back of your smartwatch. Ensure it is approximately 2.54mm.
  2. Check App Compatibility: Confirm that your smartwatch uses either the "Veryfit" or "Da Fit" companion application.
