## Overview

The Celestron PowerTank 17 is a rechargeable 12V portable power supply boasting a robust 204 Wh capacity designed specifically for computerized telescopes and astronomy gear. Featuring a 17-amp hour lead acid battery, dual USB ports, a cigarette lighter adapter, and built-in AM/FM radio plus siren, it ensures extended stargazing sessions and emergency preparedness.

## Description

Take your telescope anywhere with Celestron’s largest capacity portable, rechargeable power supply. Whether you have a computerized telescope or operate your telescope using motors, Celestron specially designed this product with the amateur astronomer in mind. First, you’ll find a 12V cigarette lighter port for your astronomy gear. This battery is compatible with all Celestron computerized telescopes for maximum versatility. You’ll also find two USB ports on board to keep your smartphone, tablet, GPS, or speaker charged and ready all night long. When your eyes are dark adapted, grab the removable red LED flashlight to navigate your observing site without sacrificing your night vision. When the session is over, turn on the bright white LED flashlight to illuminate your site and ensure no lens caps or eyepieces are left behind. There’s also an AM/FM radio and siren feature built right in. When you’re not observing, keep this battery charged and at the ready for unexpected emergencies. PowerTank can help you top off a weak car battery with the included positive and negative terminals. This sealed lead acid battery offers safer and more stable chemistry compared to low-quality lithium ion batteries, and features a built-in circuit breaker for even more safety.

Review: A good and versatile product. - Well, it looks like a tank anyway. I camp out a lot. As such I've grown to appreciate having a power box available for the times I'm plop-camping (or "glamping"). I used to take a jump box with me, but I always felt a little funny (and inefficient) about something with attached jumper cables. Enter the Celestron Power Tank. Yes, it's intended to support the use of a telescope. But it can do oh so much more. For instance, there are two cigarette lighter plugs (I'm old enough where I can call them that). Plug in a suitable power inverter and you have a power outlet you can use to, say, inflate an air mattress. Two USB ports lets you charge your stuff. And there is a mack daddy spotlight on it. So it works. And as there are a two terminals on the back, with jumper cables I could theoretically use jumper cables with this. I also appreciate the off/on/charge switch...it makes it very clear what I'm doing, and it enables me to keep the unit plugged in without charging it. This is important as the instructions tell you to charge it regularly when in storage. Much easier to flip a switch while it's already plugged in, instead of unraveling a charging cable (after you spend twenty minutes looking for it) and plugging it in. The light is quite bright and can angle down. I really kind of wish it angled in all directions though, as I was using this as a tent light (and thus pointed straight up) but it kept tipping. Charging this at first use is unclear - on one hand (the printed directions) you're told to charge it for 14-16 hours out of the box, but on the unit itself you're told to charge it for 24 hours. You are then cautioned against overcharging it lest explosive gasses are generated and it explodes or something. Your takeaway - this is a easy to use and solid performer for times when you need a versatile power box. It's not overly heavy as jump boxes tend to be, it has a clever on/off/charge switch, and the light is plenty powerful for normal use. This is a winner.
Review: Excellent Remote Power For Telescopes - This is my second Celestron Power Tank. I had my original for about 15 years until recently it fell off a high shelf in the garage and, well, stopped working. Purchased this new one like my original and it appears to be like the original. A suggestion to extend longevity with this is to use a good charger instead of the power supply and internal charger that comes with it - it can easily over-charge the battery and render the Power Tank dead, and you'd have to replace the big battery. I highly recommend the "Battery Tender 12 Volt Junior Automatic Battery Charger" for this. It will keep the battery properly charged and never over-charge it. I think the reason most people may have issues with this tank is over-charging, or letting the battery go dead, which then ruins the battery also. I learned about the Battery Tender 12 Volt Junior Automatic Battery Charger long ago with my original and it lasted a very long time with zero issues. If you do use a Tender Junior charger be sure to leave the tank power switch in the off position (not chg and connect to the rear red and black battery terminals only. The Power Tank itself is well built and I use it to run a Celestron 8se, and a small 12V fan to reduce possible condensation that I point at a camera and lens on a SkyTracker mount I usually setup near my telescope. I use a dew shield for the telescope and 12V fan for the SkyTracker camera. I usually can get two full nights running both with the tank. And using the Tender Junior charger, the tank charges in much less time. I covered the main spotlight on the tank with tail-light red tape so it only shines red light. Works great.I highly recommend this product.
