USB-IF introduces fast charging logolaad
The USB Implementers Forum, the organization for the dissemination and adoption of USB, has released a new logo for certified fast chargers that use the USB power deliver specification. The fast charging specification itself is not new.
The new logo should make it clear when a charger can fast charge via the USB-IF’s power delivery 3.0 standard, Businesswire writes. Manufacturers who wish to use the logo will have to have the charger certified by the USB-IF before it can bear the logo. Thanks to the logo, consumers can easily see that they are dealing with a safe charger. The power delivery specification supports voltages of 5, 9, and 15 volts with a current of 3 amps, and even 5 amps at 20 volts. Charger, charging cable and device must then be suitable for this.

There is often a lack of clarity about chargers with a USB (C) connection. Manufacturers who make (fast) chargers that use the physical USB connector are not obliged to use the power delivery standard. Qualcomm Quick Charge, for example, uses its own specification, just like OnePlus’ Dash Charge. Moreover, the USB-IF does not oblige the use of the logos, which does not reduce the confusion.
