-
USB standard: USB 2.0 (480mbps)
-
Thunderbolt: n/a
-

-
The cable does not provide charging protocols that are not supported by the charger, i.e. if only PD65W is available without PPS, only PD65W will be available through the cable without PPS. The cable may also restrict the available charging protocols from charger.
-
Testing has determined support for PD3.1, PPS, FCP, SCP, QC4/5, Sam2A, Apple2.4, DCP. AFC. Not supported: PD AVS, AFC, QC2/3
-
When connecting a single consumer, maximum charging capability is available (e.g. PD140W) with a small allowance for cable electronics consumption.
-
The maximum power consumer (of the two connected) determines the charging protocol to be requested from the charger and determines the maximum power! (i.e. if a laptop with PD100W capability and a PD27W smartphone are connected, PD100W will be requested from the charger (and further distributed between the laptop and smartphone), even though the charger can deliver 140W.
-
If two smartphones are connected, each with the same maximum PD27W, only PD27W will be requested from the charger and further distributed to the consumers.
-
When a second consumer is connected, all available power is shared equally between the consumers. For example, when connecting a PD100W laptop and a PD27W smartphone, the laptop switches to the PD50W charging protocol and the smartphone receives PD27W and even if the second consumer requires little power (5W) the laptop is still limited to 50% of the maximum power. When two smartphones are connected PD27W max, each smartphone switches to PD13W protocol.
-
Different voltages for 2 consumers are supported (e.g. 20V and 9V).
-
When a second consumer is connected, the current is not interrupted, only the charging protocol is changed.
Key product features:
-
Flexibility: Relatively flexible
-
Surface: braided nylon
-
Color: Black
-
Max Power: 100W PD3.0
-
USB standard: USB 2.0 (480mbps)
-

The cable is unique in that it takes power (up to 100W) from USB PD protocol as input and further converts it to protocols:
-
PD: 5,9,12,15V-3A, 20V5A
-
PD PPS: 5-11V5A, 5-20V4.5A
-
Xiaomi 90W
-
QC2.0: 5,9,12V
-
QC3.0: 3.6-12V
-
Samsung 2.0
-
Apple2.4
-
DCP
-
Xiaomi's proprietary charging protocol is available also when powered by less powerful (<100W) charging adapters.
-
When one consumer is connected (the second plug must not be connected), the maximum charging capacity is available, e.g. PD100W.
-
When two consumers are connected, the energy is distributed in the following proportions:
-
100W input: 70W+30W
-
65W input: 45W+20W
-
45W input: 25W+20W
-
30W input: 10W+10W
-
20W input and below: even distribution between consumers
-
-
When a second consumer is connected, the power supply to the first consumer (which already receiving power) is not interrupted.
-
Thus, this special cable provides a unique opportunity not only to quickly charge two UsbC devices at the same time, but also to provide charging protocols that are not initially available for a USB AC adapter, such as PPS or Xiaomi.
Club3D CAC-1527 2in1 Y-cable 100W (UsbC-UsbC) (Amazon.de) (Amazon.com)
Key product features:
-
Flexibility: flexible
-
Surface: braided nylon
-
Color: black
-
Max power: PD3.0 100W (20V5A)
-
USB standard: USB2.0
-
Thunderbolt: n/a
-
Length:1.83 meters (6ft)
-
Resistance: not applicable due to power circuit in the cable.
-
The cable does not allow charging connected devices using protocols that the original device does not support. For example, if the charger is originally limited to the PD65W protocol without PPS, the PPS protocol will not appear when the cable is connected, unlike a similar cable from CUCKTECH.
-
Testing has determined support for PD3.0, PPS, FCP, SCP, QC4/5, MTK PE+, MTK PE+2.0, Sam2A, Apple2.4, and DCP.
-
PD AVS, AFC, and QC2/3 are not supported, even if they are available when connected directly to the charger.
-
The maximum power that was set by the testing laptop (capable of using 90W from PD protocol) via this cable is 90W via PD3.0 protocol (the second cable output was not connected).
-
When the laptop and smartphone were connected simultaneously, the laptop was switched to the PD65W protocol, and the smartphone received PD18W (without PPS).
-
When two smartphones were connected, neither of them was connected via the PPS protocol, only PD, and both were limited to the same power of PD13W and a maximum current of 1.5A.
-
When only one smartphone was connected, the PPS protocol was enabled with a maximum power of up to 40W (9V-4.5A).
-
The E-maker chip was not detected on any of the cable plugs, while the activation of the PD90W protocol indicates that the functionality of the E-maker chip is implemented differently than in conventional PD 5A cables.
-
When connecting/disconnecting the second device, both consumers are disconnected for 2-3 seconds, during which time the charging protocols are renegotiated.

When the laptop and smartphone were connected simultaneously, the laptop switched to the PD50W protocol, and the smartphone received PD13W (without PPS).
-
When only one smartphone was connected, the PPS protocol was enabled with a maximum power of up to 30W (9V-3.4A).
-
The E-maker chip was not detected on any of the cable connectors, while the activation of the PD90W protocol indicates that the functionality of the E-maker chip is implemented differently than in conventional PD 5A cables.
-
When connecting/disconnecting the second device, both consumers are disconnected for a fraction of a second, during which the charging protocols are reinstalled.
-
When connecting two PPS-compatible smartphones separately, neither PPS protocol is activated, only the fixed PD13W (9V1.5A) on both devices, although these smartphones are capable of activating more powerful PD3.0 charging than 13W on chargers without PPS support.
