A:AnswerYes, it was designed to fast charge the iPhone 12 at the 20 watt power level (iPhone 11 and older only supported up to 18 watts power). This results in a slightly faster charge if your phone supports it compared with the usb-c 18 watt charger or the older usb-a 5 watt or 12 watt chargers.
A:AnswerI would purchase the Apple 20W power brick. I had mines price match to Walmart which is having a sale for 16.99 as of this writing. I believe the quality is better than the aftermarket versions. The bigger size should allow the power brick to cool faster than the smaller versions with the same power ratings. Good luck!
A:Answerthe charger rating is simply the maximum possible output, and the actual load is controlled by the device being charged. Your Apple Watch will only take as much power as it wants. My watch has been charged with a 30W charger, no problems.
A:AnswerYes it will, but you’ll have to purchase the newest charging cord made to fit this box it’s got a different connector end that fits the box. Re: to pictures
A:AnswerIf you are speaking about the iPhone 15 and the iPhone 15 pros and 15 pro maxes yes it does. The phones come with the usb-c cable but they don’t bring the charging block. This one works well !
