Very poor build quality, the Anker 521 or Anker 535 would both have been better, or the Sharge Storm2 works for about 3-4 few hours as it has direct DV12V out. The PowerPacs website is also particularly poor for documentation.

For use with the 1.5x Extender: To use with the ASI2600MC you do need the TKA31201 CA 35 Adaptor plus the OU073 M54 to M48 Adaptor.
But you will need to substitute the 21mm T2 Adaptor that ships with the ASI2600MC with a Baader Varilock 29 and set that to 20.2mm to achieve the necessary 56.2mm back focus distance from the TKA31201
