FAQ

Q: How to choose a suitable USB wall charger?

1) Power matching: on-demand selection, not blindly chasing high

Single device reference:

Phone: 20W-45W (iPhone 20W/30W, Android flagship 45W-120W)

Tablet: 30W -65W

Lightweight laptop: 65W – 100W (PD 3.0)

Gaming laptop/workstation: 100W – 240W (PD 3.1 EPR)

Total power: Multi port chargers look at the total output power, not the number of ports. For example, it is recommended that the total power of 4 ports be ≥ 60W.

Principle: The charger power should be equal to or greater than the maximum demand of the device. If it is too high, it will not accelerate and waste money.

2) Fast Charging Protocol: Deciding on 'True Fast Charging'

General Agreement (required):

OUSB PD 3.0/3.1: Cross platform universal, supports laptops/phones/tablets

OPPS: PD Upgraded Version, Voltage Fine Adjustment, Lower Temperature, Essential for Android Flagship

OQC 4+/QC 5: Universal for Qualcomm Android

OUFCS Fusion Fast Charging: A domestic universal protocol with wider compatibility

Private agreement (as needed):

Huawei/Honor: SCP/FCP (66W/80W/100W)

OOPPO/OnePlus/realme: VOOC/SuperVOOC

Xiaomi/Redmi: Pengpai Fast Charge/QC4+

3) Interface and Material: Practical and Durable

Preferred material: Gallium Nitride (GaN) -50% smaller in volume, lower in heat generation, and higher in efficiency with the same power, will be the mainstream choice by 2026.

4) Multi port power allocation: avoid "slow down with just one delay"

When charging multiple ports simultaneously, observe dynamic power allocation:

Example: 65W 2C1A → Single C-port 65W, Double C-port 45W+20W, C+A 45W+18W

Prioritize selecting models with high power reserved for the main C-port (such as 45W+for laptops).

Q: What is fast charging? Why do I need it?

To enable the fast charging function of the device, first confirm that your device supports fast charging and determine its maximum power. Then, purchase a charger and data cable that support this power. Fast charging refers to the charging speed of a device being faster than standard charging, and it needs to meet the following conditions: (1) the device supports fast charging; (2) Appropriate power supply; (3) Understand the maximum charging speed of the device.

Q: What impact will high or low power supply of the device have on charging?

Consumers usually do not need to worry about excessive power when charging their devices. Most wall chargers are designed to provide appropriate power to the device, so the risk of excessive power is extremely low. However, insufficient power is a more common issue that can result in slow charging speeds and even damage to device components.

For example, if you use a 45W charger to charge a device that only requires 20W power, the device will only consume the required 20W power and therefore will not cause any damage. However, using a 10W charger to charge devices with a minimum charging power requirement of 20W may result in slower charging speed and even damage to the device or battery.

Q: Will wall chargers damage battery devices?

Qualified charger: will not be damaged. The built-in intelligent chip will dynamically match the current according to device requirements, and automatically cut off when the voltage is unstable or fully charged.

Poor quality charger: will be damaged. Unstable voltage and high ripple can cause power IC breakdown or accelerate battery aging during long-term use.

Does fast charging damage the battery?

In theory: Yes. High current generates more heat, and high temperature accelerates the chemical decay of the battery.

Actually, it can be ignored. The phone has temperature control and trickle protection (speed drops after 80%), and there is no noticeable difference within two years of normal use. The real damage to the battery is playing large games while charging (continuous high temperature) and frequently shutting it down.

Q: What is USB-C PD 3.1?

USB-C PD 3.1 is a transmission standard that enables high-power power supply through the USB-C interface. It integrates two core functions on one cable:

Powerful fast charging: The output power can reach up to 240W, which can power devices such as gaming laptops and monitors.

High speed transmission: Supports high-speed data transmission while charging.

This design maximizes the flexibility and functionality of the USB-C interface.
