It will likely work. However, if the devices draw too much current, then a fuse will likely blow somewhere in the car, and everything will stop working until that fuse is replaced.
If I were you, I'd try it. If a fuse blows, you have three options...decrease the number of devices you're trying to power, wire the devices more permanently with larger wire, or buy an aftermarket cigarette lighter receptacle and run a larger wire from your battery to it.
