If your iPhone is not charging on the OntheGo Qi2 2-in-1 Wireless Charger (ST-QTG21K, ST-QTG21W, ST-QTG21R), the cause is usually the power adapter, the case on your phone, or alignment on the pad. The OntheGo Qi2 2-in-1 Wireless Charger includes a USB-C cable but no power adapter, and it needs a USB-C power adapter rated at 30W or higher to charge properly.

How to fix charging problems on the OntheGo Qi2 2-in-1 Wireless Charger

1. Unfold the OntheGo Qi2 2-in-1 Wireless Charger so the Qi2 phone pad and the Apple Watch module are both exposed.
2. Plug the included USB-C cable into the USB-C port on the rear of the charger, then into a USB-C power adapter rated at 30W or higher. A power adapter is not included, and a single-port adapter gives the most reliable results.
3. Do not power the charger from a laptop USB-C port. Laptop ports are not designed to deliver the steady power the OntheGo Qi2 2-in-1 Wireless Charger needs.
4. Place your iPhone face-up and centered on the Qi2 pad. A magnetic click confirms correct alignment. If you do not feel that click, slide the phone until it snaps in.
5. Remove thick or metal cases. Cases must be no thicker than 3 mm and free of any metal housing or plating, since metal blocks wireless charging.
6. Check whether your phone has built-in magnets. iPhone 13 and later models with built-in MagSafe or Qi2 magnets attach directly. Older iPhones and most Android and other Qi devices need a magnetic case or a magnetic adapter ring so they align with the charging coil and hold in place.
7. Try a different USB-C cable. A cable that does not carry power properly is the most common cause of charging that starts and stops.
8. Try a different wall outlet.
9. Place a different device on the pad to see whether the issue follows the charger or the phone.
10. Keep credit cards, key fobs, and other magnet-sensitive items away from the charging surface while charging.
11. If charging works but feels slow, check the adapter first. The iPhone side of the OntheGo Qi2 2-in-1 Wireless Charger delivers up to 15W and the Apple Watch side delivers up to 5W. Each side has a fixed speed, so charging only one device will not make that side faster, and a lower wattage adapter will charge at reduced speed.
