I image all night, and have found I need at least a 500Wh unit, although I
have ran out before but rarely (depends on the temp, length of night, and
dew zapper usage), so I have a couple of units. The Jackery Protable Power
Station
<https://www.amazon.com/gp/product/B07SM5HBK1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1>
is reasonably priced, and works nicely.
I run the C-11 with iOptron CEM60EC mount, a Laptop and accessories
(Including Dew Zapper in winter and spring) on these.
You also may need to use this calculator to help compare units since some
units show capacity in mAh and other in Wh. You will need to know the draw
(voltage). For the units showing mAh, they usually are for 12 volts.

My preference goes to jump starting battery packs with a 12v output option.
It's a nice thing to keep in the car, even when not using the telescope.
If you want something more compact, I've also used this one for several
years and am happy with it: https://www.amazon.com/gp/product/B00DN0KBXU/

The nice thing about this one is that you can change the output voltage (5V
/9V/12V/16V/19V/20V) which I've used successfully to power a laptop in the
field (useful for astrophotography)
