When using both USB-C ports simultaneously, we recommend using the upper port for charging laptops.

Apple’s power-cable identification guide for details about figuring out which cable is which. Apple In the end though, it’s what’s inside a cable that matters the most and the Apple USB-C cable has top-notch wiring materials that can deliver the most power to your laptop, phone, or tablet. Want to charge your laptop at 100 watts all day? That shouldn’t be a problem for the Apple USB-C Charge Cable. Thunderbolt 3 is a data-transfer standard that can carry up to 40Gbps of information. It was built to work only with the USB-C connector style and specification. It can also carry all the kinds of traffic noted above for “plain” USB-C devices.Some USB-C cables feature a chip or e-Marker that contains information the device reads. This two meter cable’s e-Marker is incorrect. This heavy-duty braided option is a good choice for taking advantage of the most modern charging standards USB-C is a broadly defined connection and cabling format, rather than a protocol for defining specific kinds of data that passes over it. Hardware devices—like the 2015 to 2018 12-inch MacBook and some non-Apple smartphones, tablets, and laptops—use USB-C to carry USB 2.0, 3.0, and 3.1, as well as ethernet networking and DisplayPort/HDMI video signals (and even DVI and VGA!) via adapters.

There are many 100W multi-port chargers out there, but if it doesn't have Power Delivery, just turn around and walk away. Just walk away! Without a Power Delivery USB-C port that can offer 87W or more — preferably 20V/5A 100W charging if your devices support it — then it's only useful for charging a bunch of smaller devices. That can be useful but if you need to render out a project while charging your PC as much as possible, you'll want full power.Charge multiple devices at once with a total output of 100W, delivering rapid charging speeds to keep up with your busy lifestyle. iPhone 14 / 14 Plus / 14 Pro / 14 Pro Max / 13 / 13 mini / 13 Pro / 13 Pro Max / iPhone 12 / 12 Pro / 12 Pro Max / 12 mini / SE 2020 / SE (2nd and 3rd Gen) We didn’t test the temperature of each cable’s housing, but we did test the cheapest cable by running it at 5 amps and 20 volts for an hour. The housing heated up by 50 degrees Fahrenheit, and the cable itself became relatively warm (see the thermal image below). Not ideal, but it did this without failure. We subjected other cables to two-hour loads without failure, as well. Micro Type B) can’t pass a lot of power. They mostly manage USB 2.0 data (480 Mbps) plus no more than 15W (5 volts at 3 amps), which is enough to charge smartphones and tablets. These cables may have USB 3.0 SuperSpeed (SS + a USB logo) or similar branding or logos on one tip. Or not!(See figure above.) You’d think you could tell whether a cable is USB-C 2.0 cable by looking at the wires in the connector but that’s not the case. Some cables use connectors with pins that aren’t hooked up to anything.

We then looked at how fast the cable would charge and transfer data, and whether it supported an alternate mode to run a monitor, using real-world hardware. sells such a cable. These cables will always have the Thunderbolt lightning-bolt logo on each USB-C tipped cable end. For charging speeds we recorded the maximum wattage at which the cable could charge an Asus ROG Strix 15 gaming laptop over its USB-C port using USB-Power Delivery with an Aukey 100 watt USB-PD charger as the source while the laptop was under load.USB-PD today is limited to 100 watts (with a 240-watt spec on the way). Any USB-C to USB-C cable should handle 3 ampsat 20 volts, or 60 watts.All of the USB-C to USB-C cables fell into the standard 60-watt or 100-watt camps. The trouble intrudes when we talk about power delivery, a separate part of the USB specification and incorporated into USB-C and Thunderbolt 3. Before USB-C, even though it was possible to carry laptop levels of power over a USB cable designed for that purpose, manufacturers generally avoided this—probably to avoid cable confusion. Anker Due to MacBook charging identification, it is normal to see a plug symbol in the battery icon when charging a MacBook with a third-party wall charger. Charging will revert to normal automatically after around one minute.
