If your device is not charging on the 3-in-1 Foldable Wireless Charging Stand with Qi2 25W, try these steps:

1. Use the included charging cable and 45W USB-C power adapter for the best results. If you use a different cable, make sure it supports fast charging (Power Delivery). If you use a different power adapter, make sure it can supply at least 45W to the charging stand.
2. Plug the charger into a different wall outlet or power source.
3. Clean the charger's USB-C port with a quick burst of compressed air to clear out any dust or debris.
4. Remove any phone case thicker than 3 mm, along with any case that has a metal plate, since these can block wireless charging.
5. Center your device on the charging pad so it lines up with the charging coil.
6. Try charging a different device. This shows whether the issue is with the charger or with your original device.
