The choice of charger directly affects the life of the device, charging efficiency, and even safety. Faced with various types of chargers on the market, consumers often don't know where to start. This article will focus on three core issues, combined with the latest industry data and technology trends, to provide you with a scientific and practical purchase guide.

How to choose the most suitable mobile phone charger?

When buying a mobile phone charger, the five key factors of power, protocol, interface, certification, and brand are indispensable, helping you to charge safely and quickly without damaging the phone!
The following is a detailed purchase guide:

1. Choose the appropriate charging power

Insufficient power will lead to slow charging, and excessive power may damage the battery. Appropriate power can bring out the best charging performance of the mobile phone.

• Normal charging: 5W~10W (slow charging, suitable for night charging).
• Fast charging: 18W~30W (basic fast charging for most mobile phones).
• Super fast charging: 30W~120W (both the mobile phone and the charger need to support private protocols).

2. Confirm the charging protocol of the mobile phone.

Fast charging protocol compatibility is another major point. The mainstream protocols in 2025 include:

Public protocol (universal)

• USB Power Delivery (PD 3.1): highly versatile, supports up to 48V voltage, and is compatible with mainstream brands such as Apple and Google.
• Programmable Power Supply (PPS 3.0): real-time fine-tuning of voltage/current (3.3V-21V/0.1A-5A), the temperature difference is 40% lower than traditional fast charging, and is mostly used by brands such as Samsung and Xiaomi.
• Qualcomm Quick Charge 5+ (QC 5+): Qualcomm solution, compatible with PD protocol, suitable for Snapdragon models.

Private protocol (brand exclusive)

• Huawei SCP 6.0: 88W fast charging, third-party chargers may limit the power to 25W.
• OPPO VOOC 5.0: 80W low-voltage fast charging, excellent temperature control.
• Xiaomi HyperCharge 2.0: 200W ultra-fast flash charging (laboratory data).
• vivo FlashCharge 4.0: 120W wired + 50W wireless dual fast charging.

3.Interface Selection

The USB-C interface has become the mainstream, with better compatibility, and can also charge other devices. The old interface may be eliminated.

4. Look for products with safety certification

The certification mark means that the product has passed strict testing and can effectively prevent safety hazards such as overcharging and overheating, protecting equipment and personal safety.

5. Choose a regular brand

Regular brands use solid materials, excellent workmanship, and perfect after-sales service. Miscellaneous brand chargers may falsely mark parameters and pose safety hazards.

In short,sufficient power, correct protocol, matching interface, complete certification, and good brand. The charger that meets these five conditions is the right choice!

Is a GaN charger worth buying?

Gallium nitride technology is a revolutionary breakthrough in the field of charging in recent years. Compared with traditional silicon-based chargers, GaN chargers are more than 50% smaller in size, have a 30% increase in heat dissipation efficiency, and support higher power density.It not only improves portability, but also can cope with the rapid iteration of charging technology.

If you are looking for a GaN charger that can charge all your devices at the same time, IDEAL's 102W GaN 2C+1A Charger will be your ideal choice.

20W vs 30W charger, how to choose?

Choosing a 20W or 30W charger depends on the device requirements and usage scenarios.

Performance difference

• Charging speed: 30W is about 30% faster than 20W. For example, it takes 30 minutes for an iPhone 15 to charge from 0% to 50% with 20W, but only 22 minutes with 30W.
• Compatibility: The 30W charger is backward compatible with 20W devices, and can also power tablets and thin and light notebooks, with a wider range of applicable scenarios.

The 20W USB-C Mini Charger is ideal for iPhone users, with its 20W charging power matching the official Apple charger. Its compact design makes it highly portable. In addition, IDEAL's advanced safety system enhances device safety by monitoring temperature and regulating power output, ensuring your iPhone is safe. It's an affordable, stylish and reliable charging solution.
