The Belkin 3-in-1 Wireless Charger is a great solution to charge all your iPhone, AirPods and Apple Watch at the same time.
It is reasonably priced but you do get quality for your money. You can charge all your Apple devices at full speed and so this goes pretty quickly. I myself put all my devices on the charger at night so that they are full in the morning. My experience shows that my iPhone (12 pro) takes about 2 hours to charge from 20% to 100%. If you charge at night or at your desk, this is fast enough, but wired charging remains faster.
Due to the collaboration with Apple, this wireless charger also has an MFI certification. This means that it is officially approved by Apple to use it with their devices. This certification isn't really worth much for a wireless charger, but it certainly makes me feel more secure.
The build quality of the charger is just fine, nothing special. It is made of plastic but does not feel cheap. The design is fine, it is quite compact and therefore fits easily on many bedside tables and desks.
Because your iPhone is upright, it is easy to use FaceID and quickly see incoming messages. A disadvantage of this is that it makes the charger quite inconvenient to take with you on a trip, for example, a 'charging mat' is easier in that regard.
The charger for the Apple Watch is in front of the place where you charge your AirPods. This is fine as long as you have a large or open band for your Apple Watch, because this band has to wrap around the AirPods if you want to charge them. This is really only a problem if you have one of the new stretch straps (solo/sport loop).
Furthermore, the adapter is of a specific type for this device, so you cannot use your own USB charger for this. The only issue that really bothers me about this wireless charger is the adapter. This makes a buzzing, pulsing sound (like crickets, but softer) only when there is no iPhone on the charger (if there is an iPhone on the charger, it is therefore just silent). This sound is so soft that you can't hear it if you have AirPods with music in your ears, but it can be heard at night in a quiet room. So it depends on where you plug in your adapter and whether you leave your iPhone on the charger overnight or not.
