Through various standards and charging techniques at work, it is much more difficult than it should be to determine what the cable can do. There are some things that deserve knowledge when shopping.
USB standards: The history of the Universal Serial Bus (USB) dates back to 1996, but it has seen many criteria, reviews and new types of conductors in the years. Instead of all running here, we try to highlight what matters.
Connects: Although USB-C has become a kind of standard delivery, you want cables with conductors that suit your current devices. Today, this may still mean USB-A, Lightning, or even MicroSB. Remember that the capabilities of any cable are limited to the oldest type of contact.
Data: Data transmission speed is always in Megabits per second (MBS) or Gigabits in a second (GBPS). You will know the speed that the cable should be able to according to the criteria:
- USB 2.0 480 Mbps supports
- USB 3.0 5 GB supports a second
- USB 3.1 supports 10 GB per second
- USB 3.2 Gen 1 supports 5 GB per second
- USB 3.2 Gen 2 supports 10 GB per second
- USB 3.2 Gen 3 supports 20 GB per second
- USB 4.0 40 GB supports
power: Although cable manufacturers always include the maximum charging rate, your device will determine the amount of energy that must be drawn, so it is important to know the criteria it supports and merge the cable with the correct power transformer. The cable charge rate is measured in WhatsApp (W). Sometimes, manufacturers will provide specifications on the cable in a small print. If there is no included, you can calculate it by hitting the voltage (V) and the current (A), assuming that it is listed.
The main USB-C cables can only carry up to 60 watts. Cables that can carry 100 watts or more, which are sometimes described as active, must contain electronic mark flakes that define the cable and its capabilities.
PDP PD (PD) is the closest to us to a common standard. A few manufacturers, such as OnePlus, Oppo and Xiaomi, still have ownership charging standards. Then there is a Charge Charge (QC) standard from Qualcomm, which was the most popular phones for many years, although Charge 4+ supports PD. Even PD has a variable called PPS, which is part of the USB PD 3.0 standard. PPS allows actual time adjustments to increase efficiency and shipping phones like Samsung Galaxy S22 domain At up to 45 watts instead of 18 customs, the latest addition to PD is the extended power range (EPR), which allows USB-C cables to carry up to 240 watts (it was limited to 100 watts).
Thunderbolt was a royal interface developed by Intel and Apple, but it is now open to the useless use (still accredited by Intel). With Thunderbolt 3, the standard adopted the USB-C connector and is able to transfer data up to 40 GB and can provide 100 watts of energy using a PD standard. Thunderbolt 4 brings different improvements related to the video signal (4K screens or 8K screen). It also supports the USB 4 standard and corresponds to previous standards.
Cable Certificate: There are some types of cable certificate. When the cable is adopted, this usually means that it was tested independently and corresponds to specific criteria. It gives you, as a buyer, peace of mind that your cable is like a manufacturer student. The certificate can be expensive, so many cable manufacturers avoid them, but this does not necessarily mean that its cables are of poor quality. the USB applications forum (USB-IF) is a non-profit organization dedicated to the progress of USB technology. It is managed by members such as Apple, Google, HP, Microsoft and Intel, determines the specifications and provides a certificate. If the cable is adopted by the USB-IF, it is tested to ensure its compliance with its criteria. Apple has an iPhone (MFI) certificate for lightning cables. Intel witnesses Thunderbolt cables. The approved cables are usually the relevant logo on the conductor. (For example, Thunderbolt cables contain lightning thunderbolt.)
