A single USB port of the GaN 4-Port Desktop Charger cannot deliver the full 120 W of power. The total power of the device is 120 W, which is distributed across all ports. The exact power per port can be found in the technical data sheet.
I think someone from Digitec should reply, I've seen the same behaviour.
I'd just like to say that there is a certain logic...
Given that the power supplied by the ports depends on the number of devices connected and their power requirements, I'd imagine that each time the configuration is changed, the charger recalculates the power it's going to deliver to each port, then switches off and restarts at the correct power.
Thank you very much for your feedback! If necessary, you are welcome to leave this via our star function so that it is more visible to our customers.😊 I will be happy to forward your request to the responsible department.🫡
A good charge is only achieved if the device is charged via a USBc-USBc cable, but not via a USBA-USBc cable. My son pointed out to me that USBA supposedly only delivers half the mA of USBc. Since then I have only used a USBc-USBc cable
Hello Alberto,
With my desktop charger, I have found that you have to pay very close attention to the quality of the USB cable in order to be able to draw the full power. With my devices, I was able to measure a maximum power output of 105 watts, which corresponds pretty much exactly to the specifications of the USB cable used. With 0815 USB cables, I was able to measure a maximum of 60 watts with the same device.
Cheers
Based on my several months of experience with this charger, I can confirm that the three LEDs only serve to indicate that the charger is switched on. They do not provide any information about the charging progress of a device.
USB-A can never be PD. PowerDelivery is a USB-C standard.
In the technical data sheet you can see the charging speeds of the individual and combined ports: https://static.digitecgalaxus.ch/Files...
Chargers never deliver too much power. The consumer, i.e. the headphones, only uses as much power as it needs.
So there is definitely no danger. Kind regards
Even if your Digitec GaN 120W charger is technically very powerful (up to 5 A and 120 W), this alone is not enough to activate OPPO's SuperVOOC fast charging technology.
You need both a cable and a SuperVOOC-compatible charger to achieve the full charging speed.
Honestly, it looked very clear to me and I don't know what makes me think it could be a powerbank. Also the socket to plug in indicates that it connects to the power as a transformer. Also the category where it is found is under 'mobile device chargers' and not under the 'powerbank' category.
