Celestron Telescope Power Tank-17 Power Supply Review

What Makes Celestron Telescope Power Tank-17 Power Supply Stand Out?

The Celestron Telescope Power Tank-17 Power Supply is more than just a battery pack; it’s a lifeline for amateur astronomers who want to escape the confines of their backyard and explore the cosmos from darker, more remote locations. Celestron, a trusted name in the astronomy world, designed this power supply to keep your telescope running smoothly throughout long observing sessions. Its promise is simple: uninterrupted stargazing without the worry of draining batteries.

My own need for a reliable power source arose during a particularly frustrating meteor shower. I lugged my telescope to a remote hilltop, only to have its batteries die halfway through the peak. That night, I missed countless celestial fireworks, a loss I vowed never to repeat. The Celestron Telescope Power Tank-17 Power Supply became my solution.

My initial impression upon unboxing was positive. It felt solid and well-constructed, a significant upgrade from the flimsy jump starters I’d considered. The weight suggested a substantial battery capacity, reassuring me of its ability to last through the night.

Compared to generic power banks or car batteries with inverters, the Celestron Power Tank offered several advantages. Unlike generic power banks, it’s specifically designed for telescope power requirements and provides consistent voltage. Car batteries, while powerful, are bulky and require an inverter, adding complexity and potential points of failure. It seemed like a purpose-built solution that streamlined my setup and reduced the risk of equipment malfunctions.

I was undeniably excited about the potential it held. It promised freedom from power cords and the ability to fully immerse myself in the wonders of the night sky. My initial disappointment from missing that meteor shower quickly turned into anticipation for the clear, uninterrupted viewing sessions to come.

Real-World Testing: Putting Celestron Telescope Power Tank-17 Power Supply to the Test

First Use Experience

My first test took place at a dark sky site about an hour outside the city. I used the Celestron Telescope Power Tank-17 Power Supply to power my Celestron NexStar 8SE telescope during an all-night observing session targeting deep-sky objects. The sky was clear, but the temperature dropped significantly overnight, testing the power supply’s performance in colder conditions.

The Power Tank performed admirably throughout the night. I used the telescope for over six hours, slewing frequently between targets, and the power indicator barely budged. The telescope operated flawlessly, and I didn’t experience any of the voltage fluctuations that can plague less robust power sources.

Using the Power Tank was straightforward. I plugged it into my telescope and turned it on. No complicated setup or troubleshooting was required. This simplicity was a welcome change from previous experiences with makeshift power solutions.

The only minor issue I encountered was the brightness of the red LED power indicator. While helpful, it proved a bit distracting during dark-adapted observing. I easily remedied this with a small piece of electrical tape.

Extended Use & Reliability

After months of regular use, the Celestron Telescope Power Tank-17 Power Supply has proven to be a reliable and essential piece of my astronomy gear. It has accompanied me on numerous trips to remote observing locations, consistently providing ample power for my telescope and other accessories. It has also been used at a campground, powering my telescope and phone for a weekend.

The Power Tank has held up well to the rigors of transport and outdoor use. The housing shows no signs of cracking or damage, and the battery continues to hold a charge as expected. The construction feels rugged, and the materials appear to be high quality.

Maintaining the Power Tank is simple. I recharge it after each use and store it in a cool, dry place. The instructions recommend fully charging the battery every few months to maintain optimal performance, a practice I follow diligently.

Compared to my previous experiences with unreliable battery packs and cumbersome car batteries, the Celestron Power Tank is a game-changer. It provides consistent, long-lasting power in a convenient and portable package. It has eliminated the anxiety of running out of power during critical observing sessions, allowing me to fully focus on enjoying the wonders of the universe.
