Is it Possible to Charge iPhone from MacBook? Despite the fact that Apple produces a wide range of power adapters of different power, none of them – even the coolest one at 140 watts – will charge the iPhone faster than an 18 watt charger. This will not be allowed by the hardware of the smartphone, which corny does not support faster charging.
Therefore, no matter what charger you carry, be prepared to spend at best an hour at the outlet. What happens if you connect an iPhone to a MacBook? Will the laptop be able to charge a smartphone at high speed, and if not, what will be its limit? We will answer these and other questions in this article.
Need charge iphone from macbook can occur for various reasons. For example, when there are several devices to charge. Then it makes perfect sense to connect the laptop to the outlet, and already save the discharged gadgets. After all, if you have a MacBook Pro, thanks to four connectors, you can simultaneously charge at least three devices: a smartphone, a tablet and, say, headphones. But how fast will they charge?
Is it Possible to Charge iPhone from MacBook?
The question is actually more complicated than it seems at first sight. Because what matters is not so much the power adapter to which the MacBook – Air or Pro – is connected, but the technical data sheet.
USB-C Connector Specificationswhich the iPhone is connected. We are talking about the USB 3.0, USB 3.1 and USB 4.0 standards. And, interestingly, the same Mac computer can combine ports from different generations, so separating them by model and year of manufacture is not appropriate in this case.
Apple prefers not to share the day off power supply from USB ports their laptops, and below it will become clear why this is correct, but it is known from open sources that the power delivered by the connectors of modern MacBooks ranges from 4.5 to 15 watts:
- USB 3.0 – 4.5 – 5.5W
- USB BC 1.2 – 10.5W
- USB Type-C 1.2 – 15W
Typically, all Macs come with ports of different specifications. Take modern MacBook Pros as an example: out of four USB connectorswhich carry Apple laptops, only two support the maximum output power 15W, and the other two deliver no more than 5.5 watts. Even if you plug your laptop into the mains via the 140-watt AC adapter that Apple released last year, iPhone Charging Speed from MacBook Pro will not grow.
USB power supply– the connectors do not change according to the type of computer. That is, stationary iMacs, Mac minis or, say, Mac Studios charge external devices at the same speed as mobile models. Their maximum is 15 watts. However, sometimes the iPad or iPhone not charging from MacBook: The charging icon is on but the battery is not charging. This means that the external device does not have enough voltage. Why?
The reasons can be very different:
- Faulty USB port
- Resource-intensive tasks in progress
- Other devices are supported
- The main device requires too high a voltage that the laptop cannot supply
Is it Safe to Charge iPhone from Computer?
So if Your Mac’s USB port It produces 15 watts – that’s already excellent. Especially for iPhone. Yes, this is not the maximum rate they can be charged new apple smartphones (18 W), but still quite close. So if you connect your iPhone to any modern Mac released after 2016, you can recharge your smartphone in an hour and a half. The same goes for other devices, including the iPad.
Another thing is whether it’s worth doing or, if you ask the question differently, is it safe to charge iphone from macbook? Well, frankly, there will certainly be little upside to that. Your laptop, that’s for sure. Indeed, at the time of recharging, the laptop gives the smartphone the resource of its battery, which it receives from the power supply network. By losing energy, the MacBook is forced to constantly replenish itself, which is directly a wear factor for it.
Do it right: charge iphone from macbook only once is possible without problem. It will not cause any significant damage to the smartphone or laptop. However, using a laptop as a branch to continuously charge external devices is strongly discouraged, purely for practical considerations. Just translate the convenience of this pricing method into collateral losses.
