Celestron Telescopes 2.5 amp 110v AC Adapter 18778 is a plug-in power source for many of Celestron Telescopes.Celestron 2.5amp AC Adapter 18778 replaces Celestron AC Adapters 18772 and 18773 and 18776. Celestron AC Adapter 110V 18778 is compatible with all Celestron Nexstar i, Celestron Nexstar GPS Telescopes (also compatible with Celestar 8, Ultima 2000, CI700, CG Telescopes). Because Celestron AC Adapter 18778 has a 2.5 amp (not 1.5 amps like older models) 12-volt DC output, it is compatible with larger Celestron Telescopes which require 2 amps (some models of Celestron Advanced Series Computerized Telescopes, Celestron CGE Telescopes, Celestron CPC Telescopes). And of course this Celestron AC 110 V Adapter is suitable for all Celestron Computerized Telescopes, which require 1.5 amp.Celestron Telescope AC Adapter #18778 allows a telescope to be connected to ordinary power outlet.
This AC adapter has an AC to DC transformer in the center, with a non-polarized 2-prong AC plug on a 6’ 3” cord that plugs into any wall outlet or extension cord on one side and a second 6’ 3” cord terminating in a 5.5mm female plug for connecting to the telescope on the other. It plugs into the drive base of any Celestron telescope using a 5.5mm DC input jack – such as the Celestron NexStar i, NexStar GPS, CPC, CGE, and Advanced Series telescopes (and older Celestron Celestar 8 Deluxe, Ultima 2000, CI700, CG9, CG11, and CG14 telescopes). It allows these scope to be connected to and powered by an ordinary household 110/120 Volt 60 Hz AC power outlet. The transformer has a 2.5 amp 12-volt DC output.
If used with an extension cord, do not use the transformer where the transformer/extension cord interface can accidentally be dragged into a swimming pool or puddle of standing water. Do not lay the transformer/cord interface on dew-soaked grass that might short out the transformer, or on grass where dew might be expected to form as the evening progresses. Placing the transformer/extension cord interface on a piece of insulating material (cardboard, an old rubber bathmat, etc.), putting the transformer/cord interface inside a plastic sandwich bag and zipping it shut with only the cables coming through the mouth of the bag, or suspending the transformer/cord from the telescope tripod so that the transformer can’t come in contact with dew-soaked grass might help alleviate the concerns of the ultra-cautious.
We have yet to hear of anyone turning themselves into toast because their transformer got some dew on it, but the scope and transformer manufacturers (and we) feel more comfortable exonerating ourselves from any possible liability in advance. Don’t say we didn’t warn you.
