20 volts is just a too much of a jump from the manufacturer's stamped device's voltage requirements.

Yes, I agree, there is nothing wrong with using a higher wattage than the original power adapter for powering the MacBook Air, but it has to be at least very near the originally required voltage of 14.5 Volts DC. I am surprised that no one has noticed the attempt to power a device who's stated power requirements is '14.5 Volts DC at 3.05 Amperes' (The MacBook Air) with a 20 Volts (!!) DC 85 Watts power adapter. Get a cheap unit made from chicken wire and chewing gum though, and you are asking for a fire.Īs for charging speeds, the Air likely wont charge any faster at all, but the MBP may charge slower (or, like an iPad running off an iPhone charger, not at all when in use and merely provide enough power to keep the device going). Changes are that it can supply more, say (depends on the quality of the unit) +10%.Ī high quality unit (such as an official Apple unit, not an eBay Hong Kong special) will have various safety measures to prevent all sorts of things, from overheating, over current, etc etc, and the worse you can except is the unit to fail gracefully with protected systems. There are 2 points to note here:Īlthough it isn't stated in obvious terms, the 45 W (or whatever) rating shown on the power supply isn't necessarily accurate, it is in fact the guaranteed minimum continuos rate that it can supply. If it's in sleep and just charging it will be fine, however the chance is there that if you thrash it it will start requesting more power than the MBA charger can safely provide. Assuming you use a MBP on a MBA charger, then light use will likely never draw enough power to max out the charger. The same rules apply, it will draw the power that it needs, and no more.

If you use a MacBook air that is supplied with a 45 W adapter with an 85 W adapter instead, it will still only draw what it needs, which is likely a whole lot less than the rated capacity of the charger anyway, which is rated to be able to not only keep the computer going at full bore if required, and also charge the battery at the same time.Ģ) Using a lower rated power supply than the original unit.Ĭhances are this is fine most of the time but there are more risks. The power supply will never just automatically run at 100 % of it's capability, it will only supply what is requested. With the iPhone 13 Pro Max being able to pull up to 27W of power, using 30W+ power adapters will give you the fastest charging times.1) Using a higher rated power supply than the original unit. If you’re looking for a more flexible USB-C charger or want an extra, Anker’s 36W dual-port USB-C charger and Satechi’s 3-port 66W GaN USB-C Charger are great choices to fast charge iPhones and iPads simultaneously.

iPad Pro 11-inch (1st generation and later)Īpple notes you can use its USB-C to Lightning cable or that “a comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)” will also work like Anker’s Powerline series.

iPad Pro 12.9-inch (1st generation and later).

Fast charge iPhone and iPad with MacBook chargers?Īpple says the following iOS devices are compatible with its 18W, 20W, 29W, 30W, 61W, 87W, and 96W adapters for fast charging: For example, a battery at 10% will draw more power than one at 80%. Note: depending on the current capacity of your battery, your device will pull different levels of power. Apple even does its own testing with the whole range of its USB-C power adapters. While it may sound risky, it’s safe to use Apple’s higher-powered USB-C chargers, as your iPhone or iPad is what determines the power it receives, not the charger. The good news is that modern iPhones and iPads work with all of the MacBook USB-C chargers up to the 96W model (note that Apple doesn’t recommend using its 140W USB-C charger with iPhone and iPad). Third-party options cost less, but what about using something you already have? But picking up a new USB-C to Lightning cable and 20W charging block from Apple costs $40. But what about using a higher-powered USB-C charger from your MacBook Pro or MacBook Air? Follow along for which iPhones and iPads you can fast charge with Apple’s MacBook chargers or similar third-party chargers.įast charging offers around 50% battery in 30 minutes. Recommendations to fast charge iPhone or iPad often include picking up the 20W power adapter from Apple or similar from a third party.
