Yes just plug it in no inline battery means it doesnt have a battery attached to it that it runs off - see the 3.7v PT to see what i mean - a 5v doesn't have that. Just open, plug in and go.
(Though I'd recommend getting a USB/AC wall plug rather than risk your PC ports - Ive also found my PC doesnt put out enough go-juice to power my 5v PT as well as the adapter madvapes sell
2 amp AC to USB Adapter, ideal for Passthroughs which I use all the the time with my PT)
