In the product images of the different versions, you can see that the blue contact carrier is sometimes aligned slightly differently. This is probably due to slight manufacturing tolerances in the production of the USB port. Such small deviations are normal and do not usually affect functionality. It is also possible that the contact carrier adapts and aligns slightly with repeated use of the port.
According to the data sheet under "Downloads", the fastest port USB-C1 delivers a maximum of 28V at 5A, which corresponds to 140 watts. As far as I am up to date, 200W PD via a single USB-C cable is not yet on the market.

If this is not the case with power supply units of the same power, this may be a manufacturing defect.
there are plenty cables available also on galaxus. just filter for desired power category and choose lenght you need/want. actually prefer it that way since usually the set-cable lenghts are a trade off. not long enough to move your device around a lot and not short enough when e.g. just using on your desk.
Yes, you can charge a Microsoft Surface Pro 8 with the digitec GaN 3-Port Fast Charger (65 W). This charger supports Power Delivery 3.0 and has a total output of up to 65 watts, which is enough to charge devices such as the Surface Pro 8, which is typically charged via USB-C. Make sure you use a compatible USB-C cable.
Apparently nowhere. I crawled under the table especially for you and dismantled my power supply unit from there. Oh, how nice I am again!
But to answer your question: 105g
I haven't measured mine, but the power density of this device is very high because it is so compact. It does indeed get quite hot under prolonged full load. I strongly suspect that this is normal. But if you need 63W as continuous power, I would personally recommend a more powerful device that doesn't run permanently at the limit. Just my two cents...
Under "Downloads" you will find the data sheet with the performance of the individual ports:
USB-C1:
5.0V DC/3A 15W
9.0V DC/3A 27W
12.0V DC/3A 36W
15.0V DC/3A 45W
20.0V DC/5A 100W
28.0V DC/5A 140W
PPS: 3.3-21V 5A
USB-C2:
5.0V DC/3A 15W
9.0V DC/3A 27W
12.0V DC/3A 36W
15.0V DC/3A 45W
20.0V DC/5A 100W
PPS: 3.3-21V 5A
USB-C3:
5.0V DC/3A 15W
9.0V DC/3A 27W
12.0V DC/3A 36W
15.0V DC/3A 45W
20.0V DC/3A 65W
PPS: 3.3-11V 5A
USB-A:
4.5V DC 5A 22.5W
5.0V DC 4.5A 22.5W
9.0V DC/3A 27W
5.0V DC/3A 15W
12.0V DC/3A 36W
20.0V DC/3A 60W
The intelligent power distribution will then "get the best possible" up to the limit of 240W when several devices are connected.
Unfortunately, there is no specific information in the text provided about the watts per port for the "GaN 2-Port Fast Charger (48 W)" from digitec with the product ID "DG-092BA". However, it can generally be assumed that a 48 W charger with two ports splits the power between the two ports.
Typically, such chargers support Quick Charge or Fast Charging via one port, while the other port is operated at a lower power, often around 5V/2A (10W). If both ports are used simultaneously, the power could be split so as not to exceed the total power of 48W. For example, one port could deliver up to 30W while the other port reaches about 18W.
A big factor in the daily prices is the suppliers, who either adjust our purchase prices for products on a daily basis, cancel them or add new ones. We sometimes have over 10 different sources of supply for an item in our range, and these prices are constantly changing. Major price jumps upwards occur when the previous supplier can no longer supply the item and the sales price is therefore calculated on the next most favourable purchase price. Larger price jumps downwards occur when we are suddenly able to purchase an item from a new supplier at a lower price.
With our own brand, we are the supplier ourselves; we are therefore not dependent on a purchase price from a distributor and can therefore keep the price more stable.
The GaN 3-Port Fast Charger (65 W) is suitable for the iPhone 16 Pro as it supports Power Delivery 3.0 and is compatible with USB-C. You can charge your iPhone 16 Pro safely and efficiently as long as you use a suitable USB-C charging cable.
The power of the charger is sufficient for the iPhone 16 Pro, as this device can be charged with up to 27 W and the charger delivers significantly more. The additional ports allow you to charge multiple devices at the same time.
Charging with this charger is safe for the iPhone 16 Pro battery, as modern iPhones automatically regulate their power consumption.
The power of the individual ports on the "GaN 4-Port Fast Charger (240 W)" from digitec is regulated by intelligent power distribution. There are a few important points to note here:
- The total power of the charger is 240 W, and this power is distributed dynamically to the connected devices.
- If only one device is connected, it can utilise the maximum power of the corresponding port without the power being reduced.
- If multiple devices are connected, the power is distributed intelligently to ensure that each device receives the required power without exceeding the total power.
- You can leave all four cables plugged in at all times, even if only one device is connected, without the power being reduced. The charger automatically regulates the power distribution to ensure efficient and safe charging.
It is therefore no problem to leave all cables plugged in, even if only one device is being charged.
I don't have the described laptop myself, but from what I read on the Internet, the laptop cannot be charged via a charger with 130W according to USB specifications...
The 130W Dell "USB-C" AC adapter (https://www.digitec.ch/de/s1/product/dell-usb-c-ac-adapter-130-w-notebook-netzteil-24661326) delivers an output current of 6.5A according to the specification. 6.5A x 20V then gives the 130W. However, the USB C specification limits the current to 5A in any case, as the cables and plugs are not expected to deliver more.
This is probably a case of "manufacturer overtakes specification on the right". When USB Power Delivery (PD) was introduced, the power was limited to 100W (5A x 20V). Dell probably wanted / needed more and bent the specification a bit (Dell will probably say that a specification-compliant alternate mode has been implemented - but this does not change the fact that a standard power supply according to PD version <=3.0 cannot deliver 130W). Since May 2021 and USB PD version 3.1, higher voltages (up to 48V) and thus 240W can be supplied via USB C with "Extended Power Range" (EPR) and with suitable cables. This is exactly what the digitec Charger delivers on port 1: 5A x 28V = 140W. However, the current remains limited to 5A even with the latest specification - and the power is therefore limited to a maximum of 5A x 48W = 240W. Dell is still outside the specification with its 6.5A and 130W (see e.g. https://www.reddit.com/r/UsbCHardware/comments/q5du07/130w_pd_charger/).
In short: You have done everything right, but unfortunately you still need the Dell power supply to be able to charge at the maximum speed, as Dell does not adhere to specifications.
Unfortunately, I was unable to find out whether your laptop charges with at least the standard-compliant 100W (5A x 20V) with the charger you purchased. At least with the early 130W "USB-C" laptops, not even that seemed to work (see e.g. https://www.reddit.com/r/UsbCHardware/comments/gj4d60/130w_over_usb_c/).
