How to choose an efficient, stable, multi-purpose and lightweight fast charging head for your mobile phone charger?

With the widespread use of electronic devices, households now typically own multiple gadgets such as smartphones, iPads, smartwatches, laptops, power banks, and more. As a result, chargers pile up at home, and power strips often become insufficient.

Given the frequent use of electronic devices, the demand for fast charging has grown significantly. Additionally, the portability, charging efficiency, and versatility of chargers have become essential for travel, business trips, and other outings.

Recently, Apple stopped including chargers with iPhones to reduce carbon emissions, requiring users to purchase them separately. However, official chargers are notoriously overpriced.

Many people feel uncertain about how to choose an efficient, stable, multi-purpose, and lightweight charger for different scenarios.

What You Need to Know About Fast Charging Technology:
Can fast chargers from different brands be used interchangeably?

Each brand has its own fast-charging protocol, and there is no unified industry standard.

For example, if you use a Huawei charger with an iPhone, it will not support fast charging—only slow charging, which may even damage the battery and pose safety risks.

The reason is simple: different protocols mean compatibility is rare. This gap has led to the rise of third-party charger brands.

Therefore, fast chargers from different brands are not interchangeable.** When buying a third-party fast charger, pay attention to compatibility. Opt for chargers that support **PD 3.0 + QC 3.0**, as they can charge iPhones, Android phones, and iPads.
Note: Older devices like the iPhone 7 and below or iPad mini do not support fast charging—only standard 2.4A charging.*

What is GaN (Gallium Nitride) Technology?
In short, GaN is a third-generation semiconductor material composed of nitrogen and gallium. GaN chargers are smaller, more efficient, and more stable at the same power output, enabling compact designs with high power.

Can High-Power Chargers Charge Low-Power Devices?
Apple’s MacBooks have the highest power requirements (e.g., 91W, 61W, 30W). Can a MacBook charger be used for an iPhone that supports 18W fast charging?

Answer: Yes, but with one condition—the charging protocol and cable must match.

The wattage (91W, 61W, 18W) listed on chargers refers to the **maximum output power**. In reality, the device intelligently regulates the charging power. Higher power consumption (e.g., during CPU/GPU-intensive tasks) increases charging power accordingly.

Why Does Fast Charging Slow Down After 80%?
To protect the battery, charging power drops significantly after reaching 80%. Thus, the final 20% takes longer—this is normal.

Fast Charger Selection Criteria:
1. Fast-Charging Protocol
Choose a charger that supports multiple protocols (e.g., PD 3.0 + QC 3.0).
2. Power Output
Select a charger with ≥ the maximum power requirement of your devices. Higher-wattage chargers are backward compatible.
3. Size, Weight, and Stability
Consider portability, heat dissipation, and charging stability.
4. Brand and Safety
Reputable brands ensure better quality, reliability, and safety—especially since chargers are used daily.

Since Huawei and Vivo use proprietary protocols, their official chargers are the best (but expensive). A third-party charger that supports these brands’ protocols would be a cost-effective alternative.

Introducing the ESC-C016 Charger
This charger ESC-C016supports multiple plug types (US, EU, and UK—the only charger in the market with all three built-in). Equipped with AiFAST’s proprietary chip**, it is compatible with Huawei, OPPO, Xiaomi, Vivo, Motorola, and most other brands’ fast-charging protocols.

Final Reminder
A charger is a crucial accessory—don’t overlook it. A poor-quality charger can ruin your device’s experience or even pose safety hazards.

While premium brands may cost more, they offer better reliability. Since a charger often outlasts your phone, why not invest in a good one?
