I have an evolution mount and looking for a way to power an asiair pro and asi533  camera.  Woudl the Celestron Powertank Lithium LT be a good choice?  It looks small enough to strap on the leg of the tripod.

you can strap it easily to the leg of a tripod. I am powering my CPC800 with it as you can see here:

I just do not know how long you will last with the tank. I am using it only for the CPC.

Thanks for  sending the picture.  I am only going to use it to power the Asiair Pro and asi533 camera and don't typically observe for more than 2 hours so thinking it will be enough.  It looks like the asi533 uses 22 watts of power while haven't seen definitive information on what the Asiair Pro uses.

For two hours no problem as far a I concern.

 

However be aware that you will need a splitter cable because the power tank has got only one 12 V output. AND I never tried, but it is said that you can either use the 12 V OR the 5 V USB output, but not both at the same time. If you are interested I can test it. I just read it somewhere in one of the forum.

How are you dealing with cable management for you camera?  If I am going to strap the battery to the tripod leg and then power the Asiair Pro which is riding on the scope, I am thinking I will need a long power cable so when the scope slews, I won't run into problems.
