Omegon Powertank - Always power wherever you observe
With the Omegon Powertank, you can take your telescope to places where there is no electrical outlet. Think of a dark meadow, a mountainside or a remote observation spot. You're no longer tied to your garden or balcony. Plug in and observe for as long as you want.
Ideal for GoTo telescopes and tracking motors
This power tank provides stable 12V power for GoTo telescopes and simple tracking motors. Place it next to your telescope and plug it in via the cigarette lighter socket. Your telescope will continue to operate reliably for hours, with no loss of voltage. That means accurate tracking and trouble-free observing.

Clear status, no surprises
Thanks to the LED indicators, you can see at a glance how full the battery is. You immediately know when it is ready to use or when recharging is required. This way you will never unexpectedly run out of power. With the included power adapter, you can easily charge the Powertank from any power outlet.
Handy light for set-up and observation
When setting up or taking down your telescope, you use the built-in bright light with multiple LEDs. For while observing, you switch to the red light. That preserves your night vision, so your eyes adapt well to the dark.

More than just for telescopes
In addition to 12V connections, the Powertank has USB ports. So you can also charge your phone, tablet or other accessories. One compact power source for all your astronomical equipment.
