FAQ

PPS (Programmable Power Supply) is an extension of USB-PD. It adjusts the voltage in real time to reduce heat generation and battery damage.

The cross-industry standard (supported by Apple, Android, Windows).

USB-C is the universal standard for charging processes.

Thanks to the USB Power Delivery (USB-PD) standard, you can flexibly charge everything from smartphones to high-performance laptops using a single cable and power supply. The symmetrical design also offers maximum user-friendliness.

Power classes (wattage):

The charging power varies depending on the charger, cable, and device used:

Up to 15 watts: The basic standard (5V / 3A). Ideal for small devices like headphones or smartwatches.

Up to 100 watts: The standard for USB-PD. Sufficient for most tablets, office laptops, and phones.

Up to 240 watts (EPR): Extended Power Delivery standard. Designed for extremely high-performance gaming laptops and workstations.

The most important charging protocols:

Charging power is controlled by protocols that dynamically adjust power output and voltage:

USB Power Delivery (USB-PD): The cross-industry standard (supported by Apple, Android, Windows).

PPS (Programmable Power Supply): An extension of USB-PD. Adjusts the voltage in real time to reduce heat generation and battery damage.

Manufacturer-specific protocols: Technologies such as Qualcomm Quick Charge, Samsung AFC, or Huawei SuperCharge. Often only usable at maximum speed with the respective original power supply.

Important practical tips:

Not every USB-C cable is the same: To transfer high wattages (e.g., over 60W), the cable often needs to contain a special E-marker chip. Therefore, always check the manufacturer's specifications when purchasing.

Cable length: Very long cables (over 2 meters) can reduce charging performance due to higher electrical resistance.

Safety: Thanks to intelligent communication between the power supply and the end device, you can easily charge your phone with a powerful laptop power supply. The device only ever draws as much current as it can actually process.

Yes, a power supply can generally have a higher power rating (wattage).

A more powerful power supply does not automatically deliver more current; it merely provides the maximum available power. The connected device determines how much it actually draws.

Important details for operation:

Current consumption: A device rated for 50 W, for example, will only draw the required 50 W even when connected to a 1000 W power supply.

Voltage: This must match the device's requirements exactly. If the voltage is too high, the device may be damaged.

Current (amperage): The amperage rating of the power supply must be equal to or higher than what is required by the device.

Advantages of a more powerful power supply:

Efficiency: Power supplies operate most economically (often between 40% and 70% load) when they are not running at their limit.

Noise level: A power supply that is less heavily loaded usually stays cooler, and the fans spin more slowly or not at all.

Expandability: You still have power reserves for future, more powerful components.
