Want to start with the iPhone 12, can you recommend a cheap and good charger
For example, users of the original iPhone 11 Pro series have been provided with 18W PD charging head, which can smoothly transition to the iPhone 12 without new charging head and become more environmentally friendly.
However, this strategy is hard for new iPhone users. The C-L data cable is attached randomly, which is hard to find at home, and it is hard to buy such a charger even when you go to a small store outside.
This also reflects Apple's chicken thief, this strategy behind the environmental protection, can also better sell their own accessories.
Apple sold a 20W original charger for 149 yuan.
What's more, Apple's original charger has no advantage over ordinary ones, and its volume is relatively large. It's almost the same size as the 65W Gan charger of some Android phones. It's cumbersome and inefficient to put it in your pocket.
But the good news is that Apple uses the PD charging protocol, which is a public charging protocol developed by usb-if, and is widely used in mobile phones, laptops, and even power bank.
Because of this, the iPhone 12 will not be able to reach full speed without using the original charger, just like Android phones that use private protocols. So we don't need to buy Apple's original charger, third-party charger has more and better choices.
However, it is worth noting that before charging the iPhone 12, it is necessary to modulate the message of the protocol layer into a 24MHz FSK signal and couple it to VBUS or obtain the FSK signal from VBUS to realize the communication between the mobile phone and the charger (also known as protocol handshake).
And I suggest you choose a big brand of Gan charging head. This kind of product not only has guaranteed quality, but also is relatively smaller and more convenient to carry
If you are going to buy the iPhone 12 series, it is also recommended to prepare the charger in advance, because as mentioned above, it is difficult to buy such a charger in a small shop outside, so as not to affect the use.
I'd like to share with you a good charging head, a product of domestic high-quality brand atlas.
As a brand of Lanhe Group Co., Ltd., tulas is a brand focusing on the manufacture of safety charging head. Its products have passed 3C safety inspection and PD certification. It has twice the capacitance of ordinary charging head and six layers of safety protection to avoid short circuit or overcharge of mobile phone.
While ensuring high efficiency and stability, the protection of the mobile phone is also in place, which can keep the mobile phone battery healthy and high for a long time.
This is a GaN charger with a maximum output power of 20W, consistent with Apple's original 149 yuan charger.
However, its volume is less than half of the original 18W charging head of Apple's iPhone 11 Pro Series. At the same time, it uses arc polishing design, which looks more high-end. When plugging in and out, it won't be scratched by sharp edges and corners like Apple's original charging head.
And although it is so small, its strength can not be underestimated.
This touras ice charger can charge about 60% of the power for the iPhone 12 in 30 minutes, and the iPhone 12 can be fully charged in about an hour, which is four times faster than the original 5v1a charger.
At the same time, it is equipped with intelligent temperature control chip, three-dimensional stacking technology and special shell material. When charging, the temperature is lower than the official Apple charging head of 149 yuan.
In addition, the latest iPad pro (third generation, fourth generation), iPad air (third generation, fourth generation) and ipad Mini (fifth generation) can also keep fast charging at 20W high power for a long time, so as to quickly recharge your device.
The price of such an excellent charger is only 98 yuan, which is still 1 / 3 cheaper than Apple's original charger.
The above is all my views on this issue. If you have different opinions, please leave a message in the comments area.
