Multi-port chargers can greatly simplify the desktop layout, which is a boon for multi-device users. But there are many products on the market, and the parameters are complex, how to choose the right one and not expensive? Just follow these core tips and you can become a smart buyer.

1. Core first step: calculate the total power demand

This is the most important step that determines the basic disk of the charger. Please calculate the maximum power required for all your devices to be charged at the same time.

• Common equipment power references:

• Mobile phone: 18W - 30W (PD fast charging support model)

• Flat panel: 30W - 45W

• Thin and light notebooks: 65W

• Gaming laptops/high-performance laptops: 100W - 140W

• Bluetooth Headset/Smartwatch: 5W - 10W

• Example: If you need to charge a laptop (65W) + mobile phone (30W) + tablet (30W) at the same time, then you need at least a multi-port charger with a total output power of ≥ 125W.

Tips: When purchasing, it is best to leave a margin of 10%-20% of the total power than the calculated value to ensure that the charger is not overloaded and maintain stable operation at low temperatures.

2. Understand "dynamic power distribution"

This is the "brain" of the multi-port charger, which determines how intelligent multiple devices are when charging at the same time.

• Fixed Power Distribution (Old/Low-end Schemes): The power of each interface is fixed. For example, the C1 port is 65W and the C2 port is 30W, even if the C1 port is only plugged into the mobile phone, the excess power cannot be allocated to the C2 port.

• Dynamic Power Distribution (Mainstream/Smart Solution): The charger intelligently adjusts the output power of each interface based on the type and needs of the connected device.

• Selection points: Prefer products that clearly indicate that they support "dynamic power distribution". Check the "Multi-port Simultaneous Output Power Meter" in the product description to see the actual output under different combinations.

3. Confirm the compatibility of the fast charging protocol

The protocol is the "conversation language" between the charger and the device, and the language is incomprehensible, and fast charging is ineffective.

• Core Protocols:

• USB Power Delivery (PD): Must be supported! This is a universal standard for fast charging laptops, iPhones, and Android flagships

• Qualcomm Quick Charge (QC): Mainly for Android phones with Snapdragon chips.

• Key points for shopping:

1. Ensure that the product clearly states that it supports mainstream protocols such as PD 3.0/PPS and QC 4+.

2. If you are a user of a specific mobile phone brand (such as Huawei, OPPO/VIVO), you can pay attention to whether it is compatible with its private fast charging protocol (such as SCP, VOOC), but it usually requires an original cable and the power may not be full.

4. Select the interface type and quantity

Choose based on the current condition and future needs of your equipment.

• USB-C interface: It is the absolute main force, responsible for high-power fast charging for laptops, mobile phones, and tablets. It is recommended to choose at least 2 or more C ports to adapt to future trends.

• USB-A port: Used to charge older devices such as older phones, Bluetooth headphones, small fans, etc. Select 1-2 as needed.

• Portfolio Suggestions:

• Dual device party: 2C or 1C1A

• Multi-device party/desktop users: 2C2A or 3C1A

5. Pay attention to technology and security

• Prefer GaN technology:

• GaN chargers are smaller, lighter in weight, and better controlled heat generation at the same power. It has become standard in high-quality multi-port chargers.

• Look for security certifications:

• Check whether the product has passed CCC (China Compulsory Product Certification), CE, FCC and other domestic and foreign safety certifications. This is the bottom line guarantee of product safety.

• Brand & Warranty:

• Choose a well-known brand with a good reputation and after-sales service. They provide more protection in product design, materials, and warranty (usually more than 18 months) to avoid potential safety hazards.

Before placing an order, quickly check the following questions:

1. Is the total power sufficient? Is it enough to charge all my devices at the same time with a margin?

2. Is power distribution smart? Is dynamic power distribution supported? Have you checked out the multi-port output power meter?

3. Is the protocol compatible? Does it support fast charging protocols for my laptop (PD) and mobile phone (PD/QC)?

4. Is the interface sufficient? Does the number of USB-C ports meet the needs of today and in the future?

5. Is it technologically advanced? Is it a smaller, more efficient GaN charger?

6. Is it safe? Is there a clear safety certification and a reliable brand endorsement?

By following the above tips, you can accurately screen out the most suitable multi-port charger for you, ensuring efficient and safe charging while enjoying convenience.
