what is this?

I use this charging hub I bought online. There's a hole on the side of the hub, and I don't know what it's for. I think it's for a charger, but I can't get any more info on what it is. Here's a similar item on eBay.

Appears to be the power input port.

Per the question answered by the seller here on Amazon, it's used to hook up a non-DJI charger. You will not need to use it since you're using the hub along with your DJI charger.

Or, is it to connect charging cable to remote control?

No.

What's the power requirements for a non-DJI charger? I might get a new one just for the hub.

Short answer: Use the specs on the original charger as basis.

Slightly longer version: The output voltage should be EXACTLY the same as the original charger but the amperage can be (in fact, preferably) higher since the hub can charge up to four packs simultaneously, a charger that can output higher current will help keep charging time short. That and it doesn't overwork/overheat the charger.
