In addition to powering Celestron scopes, the Power Tank 17 can also be used with 12V Meade scopes, including current LX200GPS models. However, a Meade #607 DC cord is needed to connect the Power Tank to a Meade 12V scope due to the difference between the sizes of the 12V DC input plugs on Meade and Celestron scopes. Because the Power Tank has a 12-volt DC output, it cannot be used with older Meade non-GPS LX200 scopes that require an 18V DC external power supply.
To calculate how long the Power Tank 17 will operate your particular complement of equipment, add up the maximum amperage ratings of your telescope and your telescope accessories. Divide 17 by the total draw of all your components to find the worse case number of hours that the Power Tank 17 will operate your system. Keep in mind that accessories will usually not operate continuously at their full rated amperage. A dew heater might be rated at a 1-amp draw, but that is when it is turned up to maximum power. Seldom are dew heaters turned on full and left at that setting. Operating at only 1/4 to 1/3 of the rated power is usually more typical. The actual operating time of the Power Tank 17 on a single charge can therefore often be two to three times the length of the worst-case scenario calculated above. Your operating time will depend on the ambient temperature and the particular combination of components you are using.
Unfortunately our dealer agreements with Meade, Coronado, Celestron and Orion only permits us to ship their telescopes and accessories to addresses inside the United States of America.
