3. Setup: Charging the Batteries

Before first use, fully charge your Nodinsy batteries.

Connect the dual charging cable to both 8000mAh Li-Polymer batteries.
Plug the USB end of the charging cable into a 5V/2A USB power adapter (not included). Using a 5V/2A adapter is strongly recommended to optimize charging time and maintain battery lifespan.
The indicator light on the batteries will show charging status (e.g., red for charging, green for fully charged, or a similar indication depending on the battery design).
Allow 3-4 hours for a full charge.
Once fully charged, disconnect the batteries from the charging cable and power adapter.

4. Operating Instructions

These batteries are designed for use with Nodinsy heated socks.

Connect one fully charged 8000mAh battery to the designated connector inside the sock pocket.
Carefully place the battery into the pocket, ensuring a secure fit.
Repeat for the second sock.
Refer to your Nodinsy heated socks manual for instructions on powering on and adjusting heat settings.

Follow the in-app instructions to pair your Nodinsy heated socks with the app.
Once connected, you can adjust the temperature of your heated socks and set timers for battery operation directly from your smartphone. This eliminates the need to manually access the batteries for adjustments.

The batteries themselves are not waterproof. If they become dirty, gently wipe them with a dry, clean cloth. Do not use liquids or abrasive cleaners.
