Orion Dynamo Pro 155 Wh AC DC USB Lithium Power Supply


The Orion Dynamo Pro 155wh AC DC USB Lithium Power Supply keeps all your astronomy equipment powered while in the field with its featured three 12V DC ports, three USB ports, and one three-prong AC output port.

The Orion Dynamo Pro Special Features

Impressive Versatility

Thanks to its wide variety of ports, bring it along on your next camp-out or road trip to keep all your gadgets powered up! The Dynamo Pro is the perfect “ride-along” on the base of a motorized XTg or XXg GoTo Dobsonian, so you don’t have to worry about tangling cords.

It also includes male and female auto-lighter socket adapters and an AC adapter.

Optimized Power

An indicator light will let you know the power supply needs a recharge. If no output is detected for 3 minutes, the power supply will automatically shut down saving you more battery power!

When not in regular use, recharge the Dynamo Pro every 3 to 6 months while in storage.

Red LED Technology

This power supply also features a handy red LED spotlight to help illuminate your telescope setup or campsite. Select between 5, 10, and 50% brightness settings for helpful red light while observing. You can also boost its 100% brightness setting when using red illumination.

Orion Dynamo Pro Lithium Power Supply

It works much better than the old Celestron PowerTank that I had. It is very light and runs my Losmandy GM8 and GM811 mounts very well.

Product Does Not Work

I charged this once 2 weeks ago and now its dead and will not charge. Never got a chance to use it. I'll contact OPT ASAP regarding this product.

Did great by me!

Everything with the order went very smooth! I will certainly do business with OPT again and would tell others about OPT.. The Lithium Power Supply Dynamo Pro is just as I expected. Perfect for my requirements! (and yes....I made this review of my own true experience).
