The power plug is different! Where do I get a charger?

I just bought an Inspiron 13 7000 series. So far I like it a whole lot. I like it so much, in fact, that I'd like to buy a second power adapter to keep in its travel bag. The thing that confuses me is that the plug that goes into the laptop to charge it is smaller than the standard Dell plug that I'm familiar with. This is the first Dell machine that I've seen that doesn't use the large barrel plug.

Looking on the Dell website, I can't find a single charger that looks like it will fit this machine, nor is the model listed in the compatibility list for any of the chargers that match it's power requirements. Looking at the Dell shop app that came preinstalled on the laptop itself turns up nothing in the way of actual accessories and parts for this model. Searching for the power adapter's model and part numbers on Google and Amazon brings up a surprising range of adapters from the old heavy bricks to newer slim models, all with the right power specs, but none with the right connector.

I want to throw my money at Dell, but they don't seem to want to take it. Is it possible to buy another power adapter for this model, either direct from Dell or through Amazon? If so, how do I find it?
