AC USB PD 3.2 charging adapters (wall chargers)

Key product benefits:

• The charger supports the latest PD 3.2 AVS SPR protocol with a power of 67W in standard mode (non-peak).

• The PD 3.2 AVS SPR protocol is necessary, in particular, for the maximum charging power of the iPhone 17 at 40W.

• PPS 21V support is important for some smartphones, such as the Google Pixel 9/10 Pro XL, to get 37W, and can only be achieved if the charger supports the PPS 21V protocol. 

• PPS 21V will also enable 45W charging for Samsung S25-S26 (Plus and Ultra) and 60W for S26 Ultra (SFC3.0)

• Very low standby power consumption - class VI.

• Very high efficiency - 93%

• Maximum heating 66°C at full load, no drop in output power at maximum heating (throttling) detected.

• Delta Electronics Inc., the OEM manufacturer of the adapter, has established itself as a reliable equipment manufacturer.

• Power distribution between ports:

  • One port C1 or C2: 67W

  • Two ports: 67W distributed dynamically between them (for example, the following pairs were recorded during testing: 52W(PD)+14W(PPS), 24W(PPS)+21W(PPS))

• PPS remains available even when both ports are used simultaneously - a rare feature, since in most chargers below 67W, PPS is disabled in dual-port mode.

• Both ports are equivalent in terms of power distribution. A more powerful consumer draws more power from whichever port it is connected to (the laptop drew 52W regardless of which port it was plugged into - USB-C1 or USB-C2 - while a second device was connected to the other port).

• When the second consumer was disconnected, all unused power was returned to the first port's budget (the laptop had access to all 67W without interruption).

• Weight: 151g

• Dimensions (mm): 66x28.5x56.5 (94.3 with European plug)

 

Product drawbacks:

• The reset-free feature is not fully implemented. If the charger is fully loaded, connecting a second device may (but not always) interrupt the power supply to the first device. However, if both devices together do not exceed the power capacity of the charger, there will be no interruption in the power supply.

• No PD 12V support

• No PPS 5A support for the 5-11V range, which does not allow you to get the full 45W for Samsung S22-S24 Plus/Ultra smartphones, only 21-25W.
