Earlier this year, the USB Implementers Forum (USB-IF) announced that USB-C devices will soon support 240W charging. Currently, power standards are limited to 100W, which is sufficient for most ultrabooks, but not for gaming laptops. Today the organization announced new certification logos for USB devices that support power delivery, which show exactly how fast each device or cable can charge.
There are two wattage ratings available for USB devices – 60W or 240W – and devices will be able to specify the level of power they support. Additionally, USB-IF has also revamped its USB4 certification logos, which indicate the maximum supported transfer speeds (40 Gbps or 20 Gbps). There are also specific unified logos for cables and devices that indicate both data rates and charging speeds. Additionally, there is a specific logo for certified USB chargers, indicating that they can deliver up to 240W of power to a device.
To clarify, this is not a new standard being defined today, it is just a visual representation of existing standards. Only devices that have gone through the USB-IF certification process may carry these logos or use them in marketing materials. As such, this is how consumers can determine if they can trust a given charger to power their devices.
If a cable, device, or charger bears any of these certification logos, consumers can rest assured that they will work with other devices that have the same USB power certification. The ultimate goal is to reduce confusion for consumers and prevent devices from breaking due to uncertified chargers or cables. The same goes for data rate indicators, so consumers can know exactly what speeds to expect just by looking at the logos.
“With the new higher power capabilities enabled by the USB PD 3.1 specification, which unlocks up to 240W over a USB Type-C cable and connector, USB-IF saw an opportunity to further strengthen and simplify its program. certified logo for the end user, ”said Jeff Ravencraft, President and COO of USB-IF. “With our updated logos, consumers can easily identify the USB4 performance and USB power capabilities of certified USB-C cables, which support an ever-expanding ecosystem of consumer electronics, laptops and smartphones. to screens and chargers. “
You can expect these certification logos to start appearing in marketing materials, brochures or product labels, or on the products themselves in the near future. It’s a good idea to research them before making a purchase if you want to make sure your devices are safe.
