Understand that most adapters are made to power "1 device". Any further additions only strains the adapters and it will fail or falter. The simple making of a power strip makes sense here like an extension cord.You're best bet is using a variable power box as in used for a repair bench. Most are 12V, but 24V I'm sure is present or a flick of a switch. Electronic suppliers or possible surplus vendors may offer such, google away. I supply a surplus vendor below:
Of course have an AC power strip and using individual 24V adapters brought at low cost wouldn't be a bad idea either. be sure to review the specs as in "amps/watts" values required.
I have three of the same device that run off of a 24V 500ma ac adapter. I need to know if there is a way that I can power all three from one ac adapter. If so what do i need to get and how should I run the wire. If I don't find a way to do this I will be overrun by power adapters and their cost.
