FAQ

  • Is the USB Type-C™ adapter removable from the chargesync 2-in-1 cable?

    The USB Type-CTM adapter can slide along the cable, but it is not removable.

  • With the chargesync 2-in-1 cable (micro/USB Type-C™), is it USB 2.0 or 3.1?

    The chargesync 2-in-1 cable supports USB 2.0 data speeds.

  • With the chargesync 2-in-1 cable (micro/USB Type-C™), can I charge two devices at once?

    The chargesync 2-in-1 cable combines two connectors in one. You can either charge a USB micro B device or USB Type-CTM device.

  • What is an E-marker?

    An E-marker (electronic marker) is a term to describe the authentication between the charger and the cable.  It is also called a “handshake” that confirms they are compatible.

  • What is the difference between USB 3.0 and USB 3.1?

    USB 3.0 is an old term that has been replaced by USB 3.1 generation 1 (Gen 1).  USB 3.1 is designated as having two generations. Generation 1 has data speeds up to 5Gbps, while Generation 2 has a data speeds up to 10Gbps.

  • What is the difference between a Ventev chargesync C<->C 3.1 cable and a Ventev chargesync C<->C 2.0 cable?

    While it has the same current rating, the Ventev chargesync C<->C 3.1 cable provides faster data transfer speed.

    See the chart below:

    Data Speed Current Rating Cost
    a->c 480Mbps  1.5A-3A lowest
    c<->c 2.0 480Mbps  3A mid
    c<->c 3.1 10Gbps  3A highest
  • What’s the difference between USB 2.0 and 3.1?

    The main difference between 2.0 and 3.1 is the data speed. USB 2.0 can transfer data at a maximum speed of 480Mbps. USB 3.1 can transfer data at a maximum speed of 10Gbps. USB 3.1 can also support HD video and other alternate modes.

  • Are there any other benefits to using a USB Type-C™ cable?

    Yes, data speed is another benefit of using a USB Type-CTM cable. The real benefit is experienced when using a USB Type-CTM 3.1 cable.

    Data Speed Current Rating     Cost
    a->c 480Mbps  1.5A-3A     lowest
    c<->c 2.0 480Mbps  3A     mid
    c<->c 3.1 10Gbps  3A     highest
  • What type of resistor does the C<->C cable use?

    The C<->C cable does not have a resistor. It does not need a resistor because a CC wire is present within the cable. This specific wire provides the line of communication for power negotiation between the charger and device.

  • Is the USB Type-C™ cable reversible?

    Yes, the USB Type-CTM end of the cable is reversible – there is no wrong way to plug in.

  • What does a resistor do within the A->C cable?

    The resistor value allows your USB Type-CTM device to charge safely with your existing USB chargers.

  • What type of resistor does your A->C cable use?

    Our cable uses the 56K resistor which is the approved USB specification for A->C cables.

  • Will my A->C cable damage the current charger (any USB port) I am using?

    No it will not since Ventev USB Type-CTM products are USB specification compliant.

  • When plugging in my lightning cable to my device, I received an error message stating “this device is not compatible.” Is this normal?

    In previous iOS software updates, we have seen Apple devices not recognizing the previously used cables. This does not mean your cable is defective; there may be a glitch in the software update. Before submitting a warranty claim, please clean the cable connector and charging port of the device and reinsert the cable.

  • Is my lightning cable certified by Apple®?

    Yes. All Ventev lightning products are certified by Apple®. You can find the MFI (Made for iPhone) badge on our packaging for lightning products.
