    with the 3 foot cable there is 25% less charging power, but it is still ridiculously fast

    I can reproduce the exact same effect. I have a 180 cm (6 ft) USB 3.0 extension and although the blue led lights up and it claims to be dash charging, it is not: Amperage is only 600mA.

    I have an USB 2.0 extension with the same length which charges at about 1000mA.

    This was tested under the same percentage: About 80% battery remaining.
    The USB 3.0 cable is not defective and tested on computer where the phone charges at 350mA.

    The specs of the tested cables are:
    USB 2.0: 28AWG/2C+24AWG/2C
    USB 3.0: AWM STYLE 20276

    I can assure you that the complete Sabrent Type-C to USB-A 3.0 Sync and Charge Cables 6ft 22AWG does NOT provide DASH charging on the OnePlus 3T.
    This is a standard sync/charge cable, NOT an extension.

    Just ordered a 10 footer in white. Thanks for the tip, I don't understand why the supplyed cable is so short. The shortesh cable I have ever received with a phone was 6 feet.

    Interesting to see this topic is [somewhat] still active after 2 years. For those referencing mAh readings via an app while using long cables, I wouldn't put too much weight in those findings. I would simply time the charge cycle and see if it is within 10% of the stock Dash charge using only the OEM cable.

    The key difference between the more traditional Qualcomm 3.0/4.0 and the OnePlus (VOOC - aka Dash) fast charging technologies is that while Qualcomm uses higher voltages to charge batteries, VOOC relies on delivering a higher amperage at a LOWER voltage.

    Example: Quick Charge 3.0 goes up to 6.5V at 3A, creating 19.5W, whereas VOOC delivers 5V at 4A to attain 20W. And that has a few advantages - such as the battery temperature is kept in check better and you can multitask while charging faster.

    The bottom line is -
    YES, cable voltage drop can affect Dash performance so it is important to get the best gauge wire possible within the cable(s).

    Here are some calculator shots and the proper formula showing the potential voltage drop using the 22AWG extension cable:

    With that said, I suggest the potential drop target should be kept below 10% so that could be a reason why the included OnePlus cable is short. Again, it's all in the quality of the cable and making sure the (2) USB3.0 DCV lines are active. Also, try measuring the actual time it takes to charge the phone and not what a watt meter tells you. There is a certain level of spoofing going on when attempting to test wattage outside of a Lab environment.
