A leaked support document shows that Apple may be planning to introduce a two-port 35W USB-C charger. The support document was only on Apple's website for a short time, but there was a mention of the charger.
Apple has a current 30W power adapter.
It is possible that Apple has something in the works, as there is no dual port power adapter available. 35W can be used to charge or power a wide range of Apple devices. It would be powerful enough to accommodate fast charging for the iPad.
35W of total charging power, not 35W for each port, will be provided by the power adapter.
Use the Apple 35W Dual USB-C Port Power Adapter and a USB-C cable (not included) to charge your device. Connect a USB-C cable to either port on the power adapter, extend the electrical prongs (if necessary), then plug the power adapter firmly into the power outlet. Ensure the power outlet is easily accessible for disconnecting. Connect the other end of the cable to your device.
There is no word on when this accessory might launch, but it could possibly be the GaN power adapter that Apple analyst Ming-Chi Kuo said Apple was working on in early March. Apple is working on a new form factor design for a 30 watt power adapter, with the company planning to introduce it at some point in 2022.
He said that the technology will allow for a smaller, lighter form factor because of improved power efficiency. Last year, Apple launched its first GaN charger.
Some accessory companies have been making GaN chargers for a while now, and they offer a number of multi-port options.
