So this is capable of charging my JR Q, and reciever

Yes it is and you can do both at the same time, fast charge or trickel.

Do I have to purchase leads that connect to my radio and receiver of is this charger equiped allready?

yes you need to buy leads...well maybe, do you have a voltage checker and leads? if so you can use them with the charger. The charger uses standard banana plugs to plug in, the outputs would need to be set up for JR. you can buy the leads for less than ten bucks.

BTW if you don't already have a volt checker and leads you NEEDED them anyway
