All our products support mainstream charging protocols (PD, QC, SCP, FCP, etc.), and are compatible with mobile phones, tablets, laptops, and other mobile devices from globally renowned brands such as Apple, Samsung, and Huawei. Please provide your device model before purchasing, and we will assist in confirming accurate compatibility; some products support automatic multi-protocol identification and can intelligently match the device's charging needs.

Please check the following steps:
Confirm that your device and charger support the same fast charging protocol (e.g., PD, QC).

Use our high-quality data cable; inferior cables do not support fast charging and data transfer.

Check if the charging port is making good contact.

Some phones will automatically reduce charging speed when the battery level is too high (e.g., >80%) or the temperature is abnormal.

Ensure the phone is placed in the center of the charging pad.

Remove any excessively thick protective cases, metal brackets, or foreign objects between the phone and the charger.

Confirm that you are using the matching power adapter; insufficient power can cause slow charging.

Check if your phone supports the power output of the wireless charger.

Slight heating during charging is normal. Our products have built-in temperature sensors and over-temperature protection to ensure safety. We recommend using it in a well-ventilated environment and avoiding covering it.

Buck-boost technology in car chargers refers to the core technology where the charger has a built-in intelligent voltage regulation chip that can automatically identify the car battery voltage (12V/24V universal) and stabilize the output voltage required by the device (such as 5V/9V/12V fast charging levels) through boost or buck conversion. In short, whether your vehicle is a 12V passenger car (sedan, SUV) or a 24V commercial vehicle (truck, bus), or experiences voltage fluctuations during idling/starting, a buck-boost charger can precisely adjust to ensure stable charging.

Most regular car chargers have a fixed voltage input (supporting only 12V), which has two major drawbacks:

1. Poor compatibility: Unusable with 24V commercial vehicles, limiting applicable scenarios;

2. Insufficient stability: The voltage may spike to over 14V upon vehicle startup and drop to as low as 11V during idling. Regular chargers are prone to charging interruptions, overheating, and even damage to phone batteries due to voltage fluctuations. Chargers with buck-boost functionality can stabilize the voltage in real time, supporting a wide voltage input range of 12V-24V, adapting to all vehicle models, and providing safer and more stable charging.

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).
