I got a telescope and several accessories including the celestron power tank (my telescope is a celestron). There is no way to connect the power tank to the telescope. The slot for the power into the telescope requires a special connector that looks like a phone jack. The power tank has a 4" cable with that connector, but the other end does not connect to any part of the power tank. There is no way to bridge the connection.I had to go to radio shack to buy the parts to make my own cable to connect the power tank to the telescope.
