FAQ

1. How fast is the 5W output, and will it overheat my watch?

The 5W output is the "sweet spot" for wearable devices. It provides an efficient charge while prioritizing battery health.

To ensure optimal performance:

Heat Dissipation: The premium aluminum alloy base acts as a heat sink, keeping the operating temperature within a safe range（0℃~35℃).

Input Requirement: For the best experience, please use a 5V/2A wall adapter to provide a stable power flow to the charger.

2. Is this charger durable enough for travel?

Absolutely. Designed with portability in mind, it weighs only 18g and features a compact 38mm diameter. The combination of an aluminum alloy shell and a high-grade PC surface makes it significantly more impact-resistant and scratch-resistant than standard all-plastic chargers. It’s built to withstand the bumps of travel while looking sleek on your nightstand.

FAQ

Q: What are the core technology upgrades of Qi2.2 compared to Qi2?

Power breakthrough: increased from 15W to 25W, can be charged to about 50% Qi in 30 minutes

Temperature control enhancement: When the output is 25W, the surface temperature of the charging module is forced to be ≤ 40 ℃, and the power will be automatically reduced if it overheats

MPP optimization: Magnetic alignment fault tolerance increased by 30%, making car bumps more stable

Energy efficiency improvement: Charging efficiency has increased by about 15% compared to Qi2, reducing heat generation and energy consumption

Standby power consumption: as low as 100 μ W without load, far lower than the 0.5-1W of traditional wireless charging

Q: Is wireless charging and heating normal?

Mild warmth: Normal (energy conversion inevitably generates heat)

Hot to the touch: Position deviation, thick shell, poor heat dissipation, non certified product

Qi2.2 Advantages: 40 ℃ temperature control threshold, power reduction immediately upon overheating, avoiding high-temperature damage

Q: How to identify the genuine Qi 2.2 certification?

The product is marked with the official logo of Qi 2.2 and 25W

The certification number can be checked on the WPC official website

The magnetic connection is precise, with a temperature of ≤ 40℃ when outputting 25W

There is no frequent power interruption or power drop phenomenon

Q: Can any mobile phone be charged with a wireless charger?

Only phones that support the Qi wireless charging standard can perform wireless charging. Mobile phones without built-in Qi wireless charging coils may require inserting the receiver pad or receiver case into the USB-C port. Without this support, the phone will not charge when placed on a charger.
