Assessment process
Product details
The vertical stand has a unique appearance, it can be charged at any time, no need to pick it up, just touch it to unlock Mobile phone, it is more convenient to view information, and it is also very stable to support the tablet computer.
The main body of the stand is made of aluminum alloy, and the panel part of the charging panel is made of ABS plastic, which can prevent liquid splashes.
It is not fully enclosed, and there is a cooling vent on the back.
The maximum output power is 18W, but since it only supports 2A current, so It is necessary to cooperate with high-voltage charging heads (such as 9V/2A, 12V/2A), and avoid using high-current charging heads (such as 5V/4.5A), otherwise the charging power will not increase.
< /p>
The main body weighs 118g, which is about 30-50g heavier than common horizontal wireless chargers.
Functional test
Waterproof
A small amount of liquid splashing is not a big problem, the accumulated water will flow away automatically, no need to wipe, nor affect the charging effect.
dirt resistance
The surface of the plastic is smooth, and the dust, oil and other stains can be cleaned with wet and dry paper towels, and the effect of wet paper towels is more significant.
Charging induction distance
The official claim that the maximum inductive charging distance is 2-5mm. We have passed the test of stacking playing cards (each card is about 0.3mm thick), and the actual measurement is 5.1mm for Apple mobile phones and 8.4mm for Huawei mobile phones. Both can be charged normally.
Charging speed
At 10% power, it takes about 140 minutes for iPhone 13 (capacity 3227mAh) to be fully charged, and 160 minutes for Huawei mate 40 pro (capacity 4400mAh) to be fully charged.
charging power
During the charging process, the charging power of the two mobile phones fluctuated between 7w-12w, and the power gradually decreased after the power reached 90%.
Fever status
At room temperature of 20°C, the surface temperature of the charger fluctuates around 36-44°C. According to the GB/T 37687-2019 national standard for low-power wireless chargers, the temperature of the plastic surface does not exceed 95°C, and the metal surface does not exceed 70°C. OK.
