The most distressing thing for iPhone users is that the original charger only has the ancestral 5V1A, and it takes three to four hours to fully charge.
However, after Apple released the MFi certification of CtoL data cables, cheaper Type C to Lightning cables became available on the market, and iPhone users can use PD chargers to achieve fast charging. So let’s take a look at how to choose the popular PD chargers on the market today.
We have chosen six of the more common PD chargers on the market. From left to right in the picture are the Laoqi base, Zimi three-port charger, Xiaomi 1A1C charger, Greenlink PD charger, LeTV PD charger, And Lenovo thinkplus. We used Zimi’s CtoL data cable to test iPhone charging, and the device was my own iPhone X with a battery capacity of 85%.
LeTV PD charger
When talking about PD chargers, the first thing that comes to mind is probably this PD charger from LeTV. After LeTV mobile phones withdrew from the market, they left such a "legacy". The LeTV charger that supports PD is one of the cheaper PD chargers on the market today (you need to buy it from a personal store on a certain website).
The results of the charging test using an iPhone show that the iPhone X can be fully charged from 1% to 1% in about 2 hours. During the charging process, charging starts at the highest power, the voltage is close to 6V, and the current is close to 2A. Subsequently, the current first dropped to 1.35A, continued for a period of time, and then gradually dropped. When the battery is charged to 78%, the voltage begins to suddenly change to 5V, and the current is close to 1A, which is basically the level of 5V1A. At this time, it should have returned to the ordinary charging method, and the current gradually drops until the battery is fully charged.
It was measured that it took 36 minutes to fully charge 50% of the battery. PD fast charging was used for the first 78% of the battery, and ordinary constant voltage charging was used for the last 20% or so.
This PD charger for LeTV mobile phones can be said to be "really fragrant". At a price of more than 30 yuan, it perfectly realizes PD fast charging. For iPhone users, it is cheap, compact and easy to use.
As for the shortcomings, one is that the output power supported by this charger is relatively small, and it supports relatively few protocols. The 24W power can only charge small products such as mobile phones and Switch. If you don’t buy from regular stores, you may buy fake or defective products.
Cost-effectiveness: ★★★★

Zimi three-port charger
The second product is the three-port charger launched by Zimi, which is available on JD.com You can buy on Taobao and Xiaomi Mall for 149 yuan, but there are often events and you can buy it for around 129 yuan.
This Zimi charger is relatively large in size, about the size of half a palm, with a round charging indicator light, a C port up to 45W and two A ports. The folding design at the plug is easier to store, and the white color is more attractive.
In the charging test, the Zimi charger also took about 2 hours to fully charge the phone. During charging, PD fast charging was triggered. The voltage was around 9V, the current reached around 1.3A, and the maximum power could reach 15W. Then the current dropped to about 1.1A. When it is about 77% full, the voltage drops to 5V and the current drops to 1A, returning to the normal charging level. As the current continues to decrease, the phone is fully charged.
The advantage of this charger is that it has three charging ports. It not only supports PD but also supports QC protocol. It is more suitable for users who have many products or who often travel on business. It can charge many products at the same time. At the same time, the 45W charging power can be used to charge Xiaomi notebooks, , Huawei Matebook and other products, and is applicable to more products.
The disadvantage is that it is relatively large, so you have to carry a bag if you want to take it out. Some people like the power indicator light and some don't. I think it would be fine to make it a small indicator light next to the interface. The current round indicator light is a bit exaggerated.

Lenovo thinkplus
Next is the most beautiful product in our test, the lipstick power supply Lenovo thinkplus. This is also the most expensive product among the products we compared this time. It can be purchased on all major e-commerce platforms and costs 228 yuan.
In terms of appearance, this charger is slightly larger than the size of a lipstick. Compared with the LeTV PD charger, it is slightly thinner and longer. This charger is available in red, black and white. I personally prefer the white one, which is cleaner.
During the charging test, PD fast charging was triggered at the beginning of charging. The voltage was around 9V, the current reached around 1.4A, and the maximum power could reach 15W. Then the current dropped to about 1.1A. When it is about 70% full, the voltage drops to 5V and the current drops to 1A, returning to the normal charging level. As the current continues to decrease, the phone is fully charged.
The biggest advantage of this power supply is that it supports more charging modes, with a maximum power of 65W. It can handle all mobile phones, computers, tablets, game consoles and computers on the market. It is also relatively compact and easy to carry.
As for the disadvantage, it is expensive. The price of 228 yuan should be one of the more expensive products on the market, and it only has one charging port.

Laoqi machine base
Many of the digital accessories sold by Laoqi are very good. Among them, this base phone should be the most versatile charger product on the market.
There are four charging interfaces at the base of the phone, namely two PD and two A ports. The maximum power can reach 48W. The upper part of the appearance is square and square, slightly larger than Zimi's charger, and it also uses a folding plug, making it easier to store. The workmanship looks a bit rough, and the appearance is not its strong point.
During the charging test, the phone base activated PD fast charging in the first half, and the voltage stabilized at around 9V, and the current gradually decreased over time. When the charge reached 68%, the charging reached 5V1A, and the phone was fully charged in the last 2 hours or so.
The biggest advantage of the Laoqi base is that it has two PD ports. For example, users whose computers also support PD fast charging can charge their computers and other PD devices at the same time. It can charge four devices at the same time, but the charging power will be limited when charging at the same time.
The disadvantage is that the appearance is relatively average, and the workmanship to the touch is slightly worse than the Zimi one.
Cost-performance: ★★★
Functionality: ★★★★★
Portability: ★★

Xiaomi 1A1C
Recently, the most recommended online one is Xiaomi’s latest 1A1C charger. The price is also relatively cheap, only 59 yuan.
In appearance, Xiaomi’s charger is very small, about the same size as an ordinary mobile phone charger. But it supports one PD charging and one A port charging, which is convenient and portable and has relatively powerful functions. At the same time, it has Xiaomi's consistent simple design in terms of appearance, and the plug takes up almost no space after folding.
In terms of charging, PD fast charging is also activated in the first half, and the voltage is stable at around 9V, and the current gradually decreases over time. When the charge reached 68%, the charging reached 5V1A, and the phone was fully charged in the last 2 hours or so.
Compact size and affordable price are the biggest advantages of this Xiaomi charger. The foldable plug is very convenient for storage. The two charging ports are enough for ordinary users when traveling on business.
However, this charger is often out of stock, so you still need to rush to buy it.
Cost-performance: ★★★★★
Functionality: ★★★★
Portability: ★★★★

Green Alliance PD charger
The last one is Green Alliance’s PD charger. Lulian's products have always been very cost-effective. This time, the price of the PD charger is only 29 yuan, which is the lowest price.
In appearance, there is nothing special about Greenlink’s PD charger. It looks the same as our common chargers.
Charging stage 1
Charging stage 2
During the charging test, we encountered a problem. This charger from Greenlink stopped charging after charging for a period of time. It continued to charge after replugging it. This phenomenon is speculated to be caused by problems encountered during the transition from PD to normal charging, and may be just an accidental phenomenon. The overall charging is similar to other PD chargers, with PD charging in the first half and ordinary 5V1A charging in the second half.
Overall, this charger from Greenlink has a very high cost performance and is the best choice for users who want to try PD charging but don’t want to spend too much money. However, we don’t know if the problems we encountered during the charging process were accidental and need further verification.
Value for money: ★★★★★
Functionality: ★★

is written at the end
We have compared several popular chargers on the market. For the iPhone, fast charging can be achieved. The charging time is very fast in the first half, and returns to the normal charging speed in the second half, which can meet the user's fast charging needs. However, compared with today's Android phones, which can easily be fully charged in 40 minutes, it is still a lot slower.
Among the several chargers compared above, LeTV, Lenovo, and Lulian all have only one PD charging port, which is suitable for users with few products or who only charge their mobile phones. The Lao Qi Machine Base, Zimi Charger, and Lenovo ThinkPlus have relatively high charging power, can charge computers, and are suitable for many products. The charger of Xiaomi 1A1C is small in size and can charge two products at the same time, which can meet the normal use of most users. When everyone chooses a charger, they must clarify their needs and choose a product that suits them.
