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 Micro USB 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    USB 3.0 is an old term that has been replaced by USB 3.1 generation 1 (Gen 1).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 USB Type C-C 3.1 cable and a Ventev chargesync USB Type C-C 2.0 cable?

    While it has the same current rating, the Ventev chargesync USB Type 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 USB Type C-C cable use?

    The USB Type 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 USB Type 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 USB Type A-C cable use?

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

  • Will my USB Type 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.
