One of the many highlights of the reversible USB-C connector and cable is undoubtedly the increase of guaranteed power, more than triple from USB 3.1’s 4.5W (5V 0.9A) to current 15W (5V 3A). When coupled with USB Power Delivery 2.0, output can be increased by severalfold to 100W (20V 5A) over a USB-C connection to power and recharge even the most power-hungry laptops.
That being said, there are two types of USB-C power banks and wall chargers you can buy today. The ones that leverage USB Power Delivery (PD) 2.0 standard can supply power more than the usual 15W. They are needed to recharge everything from MacBooks to Nintendo Switch.
Third-party USB-C AC chargers commonly support anywhere from 30 to 60W output whereas current generation of power banks can deliver 45W of power. In comparison, non-PD chargers and batteries are limited to maximum output of 15W (5V 3A) over USB-C.
Some of these products are supplemented with proprietary charging technologies (i.e. Samsung Fast Charge and QualComm Quick Charge). Their respective fast charging modes, however, only kick in when paired with compatible phones or tablets. In other words, they cannot supercharge your devices (e.g. Nintendo Switch, Apple MacBook, Dell XPS, Razer Stealth etc.) that comply with the USB Power Delivery 2.0 specs.
As of this writing, there are only a handful of USB PD power banks and power bricks that can recharge a USB-C laptop at full-speed while it’s under active use. Improved versions will certainly come as the technology matures and as market demand increases.
For comparison, below is a product chart featuring some of the latest USB-C power banks as well as third-party USB-C wall and car chargers we found to be worth checking out.
