Is this power supply to strong for a Midland Alan 78 plus or other CB radios?

No.

It's more 'powerful' than you need, but it will do the job admirably.

It's rated for 22 Amps, but it will only provide whatever the radio 'pulls', up to the maximum of 22 Amps.

It's regulated to provide 13.8V as long as you don't try to 'pull' more than 22 Amps from it.

Your Midland will only be 'pulling' about 2 or 3 Amps.

As long as your radio (and any accessories you may plug into it) 'pull' no more than 3 (or 5) amps.

The model I have is rated as a 7 Amp continuous (10 Amp for 50% duty cycle, 12 Amp Surge), power supply. Just in case I need it to power any accessories (ahem...).

I look at the CB power supply. The output is typically 13.8 volts. You bring a rig out of the car into the house. You were running it off a 12V car battery, now you connect it to this power supply. Am I missing something? All I could think of was that 13.8V was a off-load figure that would drop to the true 12V on-load.

13.8 is the voltage a car runs at when charging so a dropper should be 13.8 or there about as well for peak performance
