I am thinking about getting. The pocket model but I can’t fknd the stick or the Extender for it does it also come with a car charger

Not sure what 'stick' you're referring to.  FWIW, the DJI Store shows the accessories currently available and the videos show what's planned.  While no charger is shown in any of them, it appears that Power packs can be used to extend battery life and charge the battery.  

Hi, thanks for the inquiry. Sorry that we're not able to catch your concern exactly, what specific sticks are you referring? If you will purchase the Osmo Pocket, you'll be receiving Osmo Pocket, cover, smartphone adapter(lightning), smartphone adapter (USB-C) and a Power cable. You may visit the link below for your reference. Thank you for the support.

Just order the Accessory Mount from DJI Shop https://store.dji.com/product/os ... ?from=menu_products and for extension stick you can search Amazon, eBay, etc to buy whatever strikes your fancy.
