What is the best USB-C charger for iPhone? Compare the speeds and figured out

The choice of charging for a smartphone has become especially relevant after the second autumn presentation of Apple. iPhone 12 mini, iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max lost the included power adapter, and all smartphones of the current line also began to come with a cut-down package.

It will not be superfluous to replace the 1-amp block supplied with other older iPhones. In this regard, the iPhone 11 Pro officially withdrawn from sales was and remains the most profitable purchase.

Buying now, you will get not only a USB ‑ C to Lightning cable, but also a power supply 18 watts… It is too early for the owners of this gadget to think about buying such accessories. For the rest, we strongly recommend starting to look for a powerful adapter.

Now we will consider all the original solutions from Apple that are currently available.

What kind of charger for iPhone can you buy

At the moment, Cupertinos offer the following power adapters:

5W USB Power Adapter1690 RUB

12W USB Power Adapter1990 RUB

20W USB-C Power Adapter1990 RUB

30W USB ‑ C Power Adapter5490 RUB

61W USB-C Power AdapterRUB 7,490

Now let’s take a closer look at the charging speed with each of the blocks and their other characteristics.

How fast will the iPhone charge from different power supplies

All modern models of Apple smartphones, starting with the iPhone 8 and iPhone X, support one of the Power Delivery fast charging protocols.

With its help, you can get 50% of the gadget charge in about 25-35 minutes. It all depends on the adapter used and the iPhone battery capacity.

We will not be able to change the size of the battery used, but you can choose the fastest power adapter. A comparison chart of the charging speed of the iPhone 12 from different adapters is as follows:

The total charging time for iPhone 12 is:

5-watt charging: 197 minutes;
12 watt charging: 143 minutes;
18-watt charging: 111 minutes;
20 watt charging: 104 minutes;
65-watt charging: 79 minutes.

All adapters except the obsolete 5W demonstrate almost the same performance while charging iPhone up to 25%… The difference when using 12W charging from time with 65W charging will be only a few minutes. Charging from 0 to 25% is most commonly used by users. This is either feeding a completely discharged iPhone, or recharging the smartphone so that it will last a few more hours home. It is impossible to get a noticeable increase in charge speed on this segment with any of the accessories.

When charging between 25% and 75%, there is a noticeable difference in the speed of the less powerful 12W adapter. It powers the smartphone in a sparing mode, and more powerful units fill the energy almost to the limit. The total difference is approximately 10-12 minutes. There are practically no cases in which you need to charge your iPhone up to 75% 10 minutes faster.

The biggest difference in charge rate occurs in the last charge phase from 75% and above. The gain at this stage of the charge definitely does not make sense. Smartphones are charged up to 100% most often at night, where even the difference even in an hour and a half with a 5 W adapter may be insignificant. With a quick charge in the morning before work or at lunchtime, no one will wait for the last 10-20% of energy to be charged.

Do I need a USB-C power adapter for wireless charging and MagSafe

Wireless charging is supported on all iPhone models starting with the iPhone 8 and iPhone X. But the old generations of Apple smartphones up to the “twelfth” will be charged from any wireless charging with a capacity of no more than 7.5W.

For older iPhones, any QI compatible pad and 12 W or higher adapter will work. You can even add MagSafe support to older iPhones.

All iPhone 12 models can charge wirelessly with faster power up to 15 watts, but this requires a kit from the original MagSafe pills and a 20 W adapter. It makes no sense to take a more powerful one, the charging speed will not increase.

Don’t forget about the disadvantages of wireless charging for iPhone.

What is the best iPhone charger to buy?

Not profitable and slow: 5-watt power supply with regular USB port… This is an outdated power adapter that needs to be recycled. If necessary, any experienced iPhone owner will find a similar accessory in his desk.

Profitable and quite fast: 12 watt power supply with regular USB port… This option is suitable for iPhone owners that come with a USB / Lightning cable. Get a good charging speed versus a 5 watt block and be able to plug in any QI charger. And you also don’t have to buy a Type-C cable.

More expensive, but fastest: 20-watt USB-C power supply… Such a power adapter should be chosen by those who bought the current iPhone models with a Type-C cable included and all iPhone 12 owners. The former will not have to buy a separate cord, while the latter will be able to switch to MagSafe charging in the future.

Expensive and does not provide advantages: 30-watt power supply, 61 watt PSU and more powerful… Cupertinos do not prohibit this charging method, but in practice all its disadvantages are visible: the speed gain is minimal, the price is noticeably more expensive, sometimes the iPhone heats up a lot.

Why not buy an 18W USB-C box: this adapter has officially been taken off the shelves of the Apple store, but some sellers are still selling leftovers. It is on par with the 20-watt model, but charges more slowly and does not deliver the maximum power for MagSafe.

Cupertinos cheated and adjusted the prices of power supplies 12 watts and 20 watts… Six months ago, the first was sold at a price 1670 rubles, and the second (or rather its closest analogue at 18 W) for RUB 2790 Now the price is the same and the less powerful adapter has lost its main advantage.

When choosing between the same price USB-A 12 W and USB‑C 20 Вт it all comes down to whether you have a quality USB ‑ C to Lightning cable in stock.
