How to charge i9s TWS wireless earbuds?

Before you can connect i9s earbuds to your phone, you need to fully charge them. Please note that charging is not recommended with third-party chargers and that earbuds with a power button should be turned off before charging. There are two main ways to charge earbuds of different types: through the charging cable and in the charging case.

● Charging i9s wireless earbuds via cable

This method is suitable for your earbuds if you have a special cable with two connectors at one end and a USB connector at the other end. Follow the steps below to charge the cable:

​

Step 1. Connect both connectors of one end of the cable to the earbuds.

Step 2. Plug the USB connector into the device through which you plan to charge the earbuds. This can be a laptop, desktop computer, Power Bank or other device.

Step 3. Turn off the earbuds when the color of the indicators changes (e.g. from red to blue) or they stop flashing (different models).

● Charging i9s wireless earbuds in the charging case

​ 

Step 1. Connect the charging case with the included USB cable to a power source: laptop, desktop PC, power bank, etc.

Step 2. If the indicators light up, disconnect the cable from the case and the power supply.

Step 3. Place the earbuds in the case and close the cover. If a charging button is provided, press it to start charging and if you want to stop charging prematurely. The indicators light up color change means that the earbuds are fully charged. On some models, it is possible to charge both the earbuds and the case at the same time.
