Yes. Neither the 40W nor the 100W will charge the phone any faster than a 20W, if that is important to you.
You can buy more powerful chargers—at up to 100W—but they won't speed up the charging process as the iPhone can only take so much at a time. However, a more powerful charger means you can use it to power up a tablet or MacBook, too, and with multiple ports, you can charge devices simultaneously.
Yes, you can use a 100W charger for the iPhone 13 Pro Max, but it will not charge any faster than the maximum wattage that the phone supports, which is 27W. Apple recommends using a USB-C power adapter that supports at least 20W for fast charging.
As long as the charger supports Power Delivery and delivers at least 18W, your iPhone will charge at the maximum speed. It's not a problem if the charger can deliver more power than 20W. Power Delivery chargers never deliver more power than your device can handle.
You can fast charge your iPhone 8 and later up to 50 percent battery in around 30 minutes. To fast charge, you need an Apple USB-C to Lightning cable and one of these adapters: Apple 18W,2 20W, 29W, 30W, 35W, 61W, 67W, 87W, or 96W, or 140W USB-C Power Adapter.
For the iPhone 12 and iPhone 13 series, you need to use a 20W USB-C adapter, with the latter even supporting slightly higher charging speeds with 30W adapters.

Does charging your iPhone with a higher wattage charger have any negative effects? As long as the charger output voltage is correct, no. It becomes an issue if the charger delivers less wattage than the phone requires in which the phone will either charge more slowly or not charge at all.
It's a known fact that faster charging accelerates the degradation of cell phones. According to Xiaomi, 100W fast charging will cause 20% more loss of battery capacity than 30W fast charging. Most mobile devices currently on the market have a battery capacity ranging from 3,500mAh to 4,000mAh.
It will not damage the iPad.
Is it safe to charge my iPhone 14 pro max with Macbook Pro 14 67W USB-C Power Adapter? Yes, it's perfectly safe. The actual “charger” is inside your phone and will only draw as much power from adaptor as it can safely use. However it will NOT charge you phone significantly faster than a 20w power adaptor.
The iPhone 13 will only charge at about 20 watts of maximum throughput, but you can safely use higher-wattage USB-C chargers too.
That means it is completely safe to charge smaller devices such as an iPhone or Samsung Galaxy with a 60W or higher USB-C PD charger. This means you can use the same charger to charge your notebook, tablet and phone.
The short answer is to choose Apple's 30W USB-C power adapter, which at $39 is the company's lowest-priced charger that can charge the iPhone 14 and iPhone 14 Pro Max at their maximum supported charging speeds of 25W and 27W, respectively.
Power adapters and chargers rated at more than 30 watts are fine to use too, the iPhone will only draw a maximum of about 30 watts though, so you don't get any advantage of using a higher-rated charger.
This is the official charger from Apple that can quickly charge your iPhone 14 at up to 30W speed. It has a single USB-C port and can be used to charge not only your iPhone but also the iPad Pro, Apple Watch, and AirPods.
The charging circuitry is inside the iPhone and will control the amount of current that charges the phone. No matter how much power the power adapter could theoretically supply, it's safe as long as the power adapter supplies the correct voltage and the charging circuits limit the current.
Watch the wattage
For years, Apple supplied “good-enough” 5-watt chargers in the iPhone box, which take about 2.5 hours to fill up your iPhone. That was fine for the iPhone 5 and earlier, which didn't support fast charging, but the newest iPhone models are capable of working with chargers that handle up to 20 watts.
Note: For fast charging, iPhone 12, iPhone SE (3rd generation), and later models require a power adapter with a minimum power output of 20 watts, such as the Apple 20W USB power adapter. If you use a third-party power adapter, it should meet these recommended specifications: Frequency: 50 to 60 Hz, single phase.
