Just wondering if this power supply can be tricked into turning on to run battery chargers?

Most likely a remote antenna unit.

Due to their high carrier frequency 2.4Ghz radio systems have a very small wavelength, so are prone to being blocked by metal parts of model plans and things at long range when banking and turning.

By placing a second antenna in a different spot (like on each side of the model), you greatly reduce the likely hood that your engine or something will get in the way of line-of-sight between your receiver and transmitter.

So, basically it improves long range reliability. not usually required for Robot use where the machine is so close, that the Rx antenna is likely completely immersed in the near-field signal and cant be easily blocked.

would the reciever still work if the extender was cut off?

i took mine off when i bought it. as has everyone else here using them i believe. works just fine.

the extra unit plugs in too so no cutting and resoldering required.

what are the dimensions of the reciever?
(last question i promise )

I just noticed another SS radio: http://www.amainhobbies.com/product_info.php/utm_source/07_16_2009_newsletter/utm_medium/email/utm_content/5086372/utm_campaign/ProTek%20R/products_id/34416/n/Traxxas-4-Channel-TQ-24GHz-Radio-System-No-Servos

This one is not the cheapest wheel radio on the block at $139 USD, but it has 4 channels, which would make it ideal for a bot like Demon with extra features

that radio looks good. defo looking into it now apparently you can hack the 2ch one into 4ch
