Digital Cameras Photo Reviews of Celestron Power Tank
Customer Review: Useful and Reliable
Summary: 4 Stars
I have used the 7ah model for about two years to power my telescope. On a full charge, I can get through a night's observing easily. I typically observe for about four or five hours. I use the flashlight with its red cover to check the area where I have been observing before I leave to make sure I am not leaving anything behind. The flashlight is bright enough to let me check the area just by sweeping the light back and forth. I rarely use the spotlight, but on the few occasions when I have needed it, it really came through. One time I was running an outreach program called Stars and Music. The musician was to play for an hour from sunset to dark. Unfortunately, the musician had forgotten to bring a light for the music stand. Since the performance was taking place outside under a ramada, I propped the Power Tank on a vent above a grill, pointed it up toward the ramada, and turned on the spot. It provided enough reflected light to get the musician through the whole performance. Of course, the unit was drained by the end of the performance, but when it came time for the Stars portion of the event, I simply took the power cord from the unit and plugged it into the cigarette lighter of my car to power the telescope.
Another feature of this unit that serves me well is the 3v outlet. I fashioned a red-LED desk lamp to use on my observing table, and I just plug the light cord into the 3v outlet on the Power Tank. So I have power for my telescope and power for the lamp from one convenient source. The Power Tank also has 6v and 9v outlets in addition to the two 12v sockets.
I never had any trouble with the charger, but I did manage to lose it. Rather than buying a new one, I took the 12v adapter from a cordless drill and now use it to recharge my Power Tank. It works perfectly. I have, though, had problems with the power cord that plugs into the 12v socket on the unit. Twice it has failed. The problem was finally resolved when I took the plug apart and replaced the nipple (which had fallen out) on the end of the plug with a screw and washer. Problem solved.
Other than that minor annoyance, I have been pleased with the Power Tank and anticipate getting another couple of year's use from it. The four-star rating is a result of the poorly designed and unreliable plug on the power cord.
