@S.Yu - From what I've seen about USB in sockets, they ALWAYS advertise the TOTAL power. Aka, you do get 30W charging per port, but that is SHARED. So connecting 2 devices means they share the 30W.

Going to their website, and clicking details confirms just that as well:

What is the maximum charging output of the Leviton Dual Type-C with Power Delivery (PD)
USB Charger Outlet?
- Single port connected to PD-enabled device: 15VDC@2A (30W) or 9VDC@3A (27W)
- Single port connected to non-PD device: 5VDC@3A (15W)
- Both ports connected to devices: 5VDC@3A (30W total power)


It's just another one of those industry "caveats" you have to remember.(like hard drive manufacturers treat 1GB as 1000MB instead of 1024MB or how bandwidth speed is advertised in bits instead of bytes). Get used to it : /

I see... ???

The thing I've wondered about these is what happens if there is a power surge? They don't have built in surge protection do they?

Or do we have to get a whole house surge protector?


@S.Yu - it says 30W, not 60W. That said, it isn't impossible. A DART is same size as a cell phone charger and is 65W.

30W, two ports...unless it's 30W with one active but 15W each with both in use, that would be lame.

USB 3.0 charging technology built into outlets smart devices, & smart homes.represents the 1st change to the wall outlet in 85-years.

... doesn't look much of a futuristic socket to me. These American sockets still don't have on-off switches, behind the UK in 1947.

I thought it was surprising that they could fit a 60W 110-230v-15-5v transformer in there, then it occurred to me that it's likely 110V-15-5v only, so it could probably be smaller.
