Banana plugs are only good to 3 amps according to my HP power supply manual.
From experience, I can
assure you that they get hot fast.

I'll grant there are some poorly designed bananas out there, but the good
ones handle up to 15 Amps at 60V - see
<http://www.pomonaelectronics.com/pdf/d_mdp_4892_98_1_01.pdf> . I wired my
house with + and - 12V (similar to how most US houses have 240 VAC split
into 120VAC circuits) eighteen years ago, using double banana jacks
arranged so I can get +12, -12, or 24V at each tap. Haven't damaged a
single connector in all that time. My Sunfrost is hard-wired for minimum
loss, but the previous fridge, which actually took more power and at 12V
instead of 24V, was plugged in with double bananas for years.

Why not just get the cigarette lighter plugs that are readily available in auto

parts stores? I also think there are some NEMA plugs specified for 12VDC.

And they also tend to suck.

I chose the 240V connectors (that look like standard 120V except one
prong is turned at right angles to the norm) which meet code since I
don't have 240VAC in the house.

Only problem is, I'm not inclined to permanently modify my 12V stuff
with the 240V plugs, such that they can never be used in a vehicle
again. (Handy sometimes!) As a result I invariably end up plugging the
cig lighter plug on the unmodified gizmo into an adaptor into my fancy
240V connex. This is not really progress!

I guess I could put the 240V plugs on all the gizmos and then build a
lighter plug to dual 240V socket adaptor for vehicle use.

<sigh>

Life's a compromise.
