Well, on DJI's website there are the recommended chargers. I'm crazy and went with the PH4C-160W Phantom charger. It's the most expensive ($85 plus cord)but it charges those batteries RIGHT NOW!!! Otherwise the PH4C-100W ($69 plus cord) should work. If you're for sure only going to plug in the Crystalsky battery charger, then the Osmo battery charger is $50 and comes with a cord. I dropped about $100 because I was also using it with the advanced battery charging hub from the Mavic Pro. It's unclear if something like that will become available for the Mavic 2. If your budget is tight, get the Osmo charger. However, since you're getting the big dog screen, now may not be the time to get CHEAP!
Here it is on Amazon. That page also shows the cord you need for various prices $11-5, It's $65 plus the cord and they'll get it to you quick for free.

Great advice, thank you Lon. That's just helped to complete my order for the lot, much appreciated...and you're right not worth being cheap, especially since I use them for work. Looking forward to making it all work.
