Now you can take your telescope anywhere with this portable rechargeable power supply. Whether you have a computerized telescope or operate your telescope by using motors, this power tank was especially designed to fit the amateur astronomer's needs -- it is equipped with several useful features.
Not only is it the right choice for setting up and powering your scope, but it can also be used as an emergency roadside accessory, because it includes an emergency light, and booster terminals for starting weak or dead car batteries.

Please consider the following advice to improve the lifetime of your battery:

• Never discharge your battery completely. Turn off your mount before. So you can protect your mount from overvoltage.
• Do not store the battery, when it is empty.
• Do not charge the battery too long. Turn off your charging station as soon as the battery is fully loaded.
