It worked well. For less then $20, problems solved. Used my BLUETTI EB 55 as power supply, but a smaller 10,000 amp power supply would have worked fine. Review: Works very well - Astronomy. New to the hobby... and I am so glad these work as well as they do;-) Anyone who stares through a telescope on a winter night would understand. No drama, just plug it in and does the job nicely. Comes with a nice bag (some don't, I have others), has a nice cord that is easy to manage when cold. And the cord has been long enough to work fine for my needs (8"dob with a battery at it's base). I leave it on all night. In the beginning I checked the temperature regularly but now have just settled in to taking it for granted (sigh of relief) ## Features - 【Widely Used】: ***NOTE:Due to the adjustment of the controller's appearance, but the function has not changed, the inventory of the new and old versions may be mixed together, so the new and old versions will be shipped randomly.*** suitable for telescopes, viewfinder lenses, digital cameras of most sizes (Diameter less than 80mm).
