I travel a lot or live overseas where the line or mains voltage is 220 volts. What AC adapter should I use to power my Celestron scope?

Use our model #18780. It’s a switching-type AC-to-DC power adapter that provides more power with less weight than a transformer-style power adapter. An additional advantage is it uses AC input from 100 to 240 VAC. This covers almost every power system worldwide.
The AC adapter has a US-style Type A AC plug as detailed here: http://en.wikipedia.org/wiki/AC_power_plugs_and_sockets#Type_A
You may need a plug adapter when using the #18780 outside the US. Many electronics stores and outfitters like REI carry them.
