I am looking to run virtually my whole set up through a Pegasus Power box using a Albrect SW102 power supply.  The power supply has banana plug outs so I need a cable with banana plugs on one end and a 2.1 dc connector on the other… AND it needs to have a 10 amp rating so I dont risk any problems.  Perhaps over kill with 10 amps but just so.  I'm finding it rather difficult to find cables with any ampere rating and difficult to find banana to 2.1 DC.

These kind of power supply boxes are sold on many astro equipment supply stores.. but cables are sadly lacking…  Anyone know of a resource for such things. I am located in Bergen Norway

You may not find amp rating, but you typically do find the AWG (gauge) of a cable; for 10 amps you want a 16 AWG cable (which is not big at all). Anything smaller than that (yes, AWG moves the opposite direction of amps) is way overkill.

That is pretty specific. I suspect you would be better off making your own with plugs and silicone wire (especially the latter in Norway due to temps).

The main problem is voltage drop if you use longer cables. If you can keep the cable length short (<1m) you can probably get away with the standard cheapo cables.

I've been using something like this for several years without issues to distribute the power on my scope. It carries 2 cameras, filter wheel, 2 heaters, Auto focuser and a mini PC. Power supply is off the shelve 12v 10A. Total cost for power supply and cable <40€.

Teleskop service in Germany sells them. I have it for 13.8V  10-12 Amp supply. Edit: mine is also an Albrecht.

Hei @Habib Sekha .  Thanks for the link !  I see that the ampere rating is not included, but I suppose given they sell with the same power supply it will be strong enough.  I wrote TS and asked if they could check it for me.
