Celestron Power Tank

Now you can take your telescope anywhere with this portable rechargeable power supply. Whether you have a computerized telescope or operate your telescope using motors, Celestron specially designed this product with the amateur astronomer in mind -- this model is packed with useful features.

Not only useful for setting up and powering your scope, this model can also be useful as an emergency roadside accessory as it includes an emergency light, and booster terminals in place to start weak car batteries.

An all-in-one 12V DC power supply for operating your telescope and power-hungry accessories in the field. This sealed-case Celestron Power Tank rechargeable battery works with all telescopes that can be powered by a 12V DC external power supply. It is particularly useful for simultaneously operating a telescope and a CCD camera and/or a dew heater system.

In addition to powering Celestron scopes, it 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.
