Q: What wattage does this cable carry?
A: This cable supports 100W.
Q: can this cord be used to retrieve contact number and photo's from one phone and load it to another
A: Yes, I used this cable to transfer files from one USB-C phone to another. Worked like a charm.
A: Yes, it would work. Rates at 60 watts, so your 45 watt charger need should be covered.
Q: Would this be safe to charge 100 watts on my phone without an e-marker chip
A: The Insignia™ 4' USB-C to USB-C Charge-and-Sync Cable supports charging up to 100 watts. However, using a cable without an e-marker chip for high-wattage charging can be risky. The e-marker chip helps ensure safe power delivery by communicating the cable's capabilities to the connected devices. Without the e-marker chip, the cable might not properly regulate the power flow, potentially leading to overheating or damage to your phone or charger. For safety, it's recommended to use a cable with an e-marker chip when charging at high wattages. If you have any other questions or need further assistance, feel free to ask!
Q: What is the voltage and wattage rating of this item? And, is it compatible with an iphone 16 Pro?
A: Thank you for your inquiry. I would like to confirm that our charging cable is compatible with the iPhone 16 Pro. Please note that this particular cable is not yet MFi certified, as it is still in the processing stage; however, most of our Insignia cables do carry Apple MFi certification.- Carl | Insignia Support
