I'm aware tha Jr charger has a diff. polarity than the Futaba.
Can I use all them together without burning something?
Only the transmitter side of your JR wall charger has reversed polarity to match your JR tx which is the only brand that uses this on their transmitter charge plugs. The Receiver side of
your JR wall charger is not reversed from the other current brands with the centerpin positive.
