The short answer: is YES, all Click n Charge chargers work the same and can be interchanged. I later read somewhere that all the technology for Click n Charge is the same and therefore the different chargers will always work on every toy that says it's Click n Charge

My experience: I have not used your specific toys, BUT, I have some of the older chargers for the Big Boss and my Stronic Eins arrived with a wall plug in charger that has a slightly different head (domed) for the contacts. Anyway, I recently received the Stronic Drei and it has the newer, USB charger with the red cord (and no wall mount adapter). For some reason, the charger for my Eins has never worked right and died on the second use. I thought the toy was broken, but read their info on the site and realized it was the charger. So I used the charger from my Big Boss which has the flat black disc with Fun Factory printed on it and it worked great. I also have tried the USB charger with a wall adapter from my Nook and it worked great on the Drei and also on the Eins. (If you do not see the indicator light, then it is not working and usually it's the charger that is at fault, not the toy. Look for the indicator light on plug in charger models.)
