Review: Power Tank 17 - A great power source for Telescopes And More... - I have bought both the Power Tank 17 , and it's little brother (though this may be harder to find). Before my review points, please remember to charge the Power Tank after use. Don't let it get go flat, after multiple uses. It may have many Watts of power left, after each use but is a sealed Lead/Acid battery at its core. This needs a little care and time to charge after each use to keep it in prime condition. Even a top-up charge of a few hours, is recommended if not used for a few months. Note that there is a "back door" flap containing the "Cigarette lighter" cable. This is not always well mentioned. Don't go out and buy that. Unless you need another 12V outlet. It is great that there are 2 "Cigarette Lighter" sockets, but it is important to know that they are Not The Same. One is centre Negative (-ve), the other is centre Positive (+ve). For my Celestron C8, it is the right-hand; centre Positive. So if you think the Power Tank isn't working, for your appliance, try the other one ! Plus the great fuse protection provided, may need a quick check. If you are using this Power Tank for astronomy, the red light gives you the "night sight adaption", protection. You can change eyepieces and see what you are doing without any white light "dazzle". Excellent. The main beam is on a ratchet, so you can point it downwards, while walking around in the dark, great to avoid dips in the ground, tree roots etc, if out in the countryside. Which brings me to another point, that the Power Tank can be a great aid if camping/caravaning etc. I wouldn't get it wet, but when away from any mains supply, there are 2 x USB 1.5 Amp (5V) charging ports. Very usefull, for charging phones/tablets etc. I have even found the Power Tank a blessing in a power cut. Keeps a light on and phones etc running. There is the added joy of a radio on the Power Tank 17..... AM & FM ! Surprised by the tonal quality on both bands. Obviously keep volume appropriate to where you are. And then... The Siren Setting ! Who thought of that ? Initially surprised by this lovely fun function, but could be Really handy if someone is lost or needs to get attention when out camping, in a dark observing site etc. I think that the price, is fair, for such well thought-out and good capacity device. You get what you pay for. I recommend it for astronomers, with portable motorised telescopes as myself, and to all others with a need for portable power. Nice One Celestron ! Review: Good power tank - Feels like a premium and robust power tank able to power a demanding mount for a few hours. I am not given the chance to take it out and try its capabilities yet, but I will definitely update my review, if the item does not meet my expectations. ## Features - 2 x 12 V OUTPUT CIGARETTE LIGHTER PORTS: For your astronomy gear - BUILT-IN (2) USB PORTS: Charge portable devices - FLASHLIGHT AND SPOTLIGHT: Built-in flashlight with red filter cap; Energy efficient LED spotlight - CIRCUIT-BREAKER: Built-in Circuit Breaker for safety - COMPATIBILITY: Use with any Celestron Computerized Telescope ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00008Y0U5 | | Amperage | 7 Amps | | Best Sellers Rank | 164 in Telescope Accessories | | Box Contents | Cigarette lighter adapter and AC Adapter | | Brand Name | Celestron | | Colour | Black | | Compatible Devices | Camera, Smartphone | | Connector Types | CIGARETTE LIGHTER (DC), USB (DC) | | Country of Origin | China | | Current Rating | 7 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (1,413) | | Global Trade Identification Number | 00050234187749 | | Input Voltage | 12 Volts | | Item Dimensions D x W x H | 33D x 17.8W x 27.9H centimetres | | Item Weight | 8.5 Pounds | | Manufacturer | Celestron | | Manufacturer Part Number | 18774 | | Model Number | 18774-CGL | | Number of Ports | 4 | | Output Voltage | 12 Volts | | Specification Met | UL, FCC, CE, RoHS | | UPC | 050234187749 | | Unit Count | 1.0 count | ## Product Details - **Brand:** Celestron - **Colour:** Black - **Item weight:** 8.5 Pounds - **Output voltage:** 12 Volts - **Product dimensions:** 33D x 17.8W x 27.9H centimetres ## Images ![Celestron 18774-CGL PowerTank 7, 12V -7Ah, Black - Image 1](https://m.media-amazon.com/images/I/61z5ak3t2VL.jpg) ![Celestron 18774-CGL PowerTank 7, 12V -7Ah, Black - Image 2](https://m.media-amazon.com/images/I/61fkwjo+ngL.jpg) ![Celestron 18774-CGL PowerTank 7, 12V -7Ah, Black - Image 3](https://m.media-amazon.com/images/I/61TEgk1mS1L.jpg) ![Celestron 18774-CGL PowerTank 7, 12V -7Ah, Black - Image 4](https://m.media-amazon.com/images/I/51qxn2miQiL.jpg) ![Celestron 18774-CGL PowerTank 7, 12V -7Ah, Black - Image 5](https://m.media-amazon.com/images/I/61QWxQAbSPL.jpg) ## Questions & Answers **Q: Can I run a laptop from it?** A: Yes, you can. Make sure you charge the Power Pack regularly otherwise goes completely empty and you may not be able to charge and use again. My one broke down after 3 months not charged. **Q: Does this replace the battery pack that comes with Celestron telescopes (i.e. the one one with several large batteries in)?** A: yes 8 battery's will only last 3/4 hour,battery pack is a very good buy **Q: Does this come with a cable which connects to a telescope?? NexStar 8se** A: Yes. You plug the 12v cigarette lighter cable, which comes with the device, into one of the 12v sockets on the device, and the other end into the telescope. See photo at top. **Q: Will this work with my meade lx65 mount** A: The PowerTank is essentially a 12 Volt power supply if your Meade mount requires a 12 Volt supply, then the PowerTank will work for you! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Power Tank 17 - A great power source for Telescopes And More... *by A***. on 26 April 2025* I have bought both the Power Tank 17 , and it's little brother (though this may be harder to find).

Nice One Celestron ! ### ⭐⭐⭐⭐⭐ Good power tank *by M***. on 20 December 2024* Feels like a premium and robust power tank able to power a demanding mount for a few hours. I am not given the chance to take it out and try its capabilities yet, but I will definitely update my review, if the item does not meet my expectations. ### ⭐⭐⭐⭐⭐ GREAT BUT NOT VERY LONG LASTING *by C***E on 20 July 2022* Bought two of these (Β£43) in Jan 2007 to run my telescopes etc. They were excellent, plenty of power to run LX8 and LX12 and lasted most of the night. Very easy to charge, great to have a fuze as a safety backup as well, yes they took a few hours to charge but with two I never encountered any problems. Unfortunately, the first one stopped accepting a charge back in early 2011 and the second in 2014. The 2014 one, nearly 7 years I though was reasonable but not the 2011, less than four years seemed far to short a lifespan. I still have them both as bricks in my shed, can't bring myself to dump them. :-) ## Frequently Bought Together - Celestron – PowerTank 12 Telescope Battery – Rechargeable Portable 12V Power Supply for Computerized Telescopes – 84 Wh Power – Built–in 2 USB Ports, Cigarette Lighter Adapter, Built-in Flashlight - Celestron - SkyPortal WiFi Module - Control Your Celestron Computerized Telescope via Smartphone - Telescope Wi-Fi Accessory - Celestron 14 Piece Telescope Accessory Kit - Plossl Eyepieces, Barlow Lens, Colored Filters, Moon Filter, and Sturdy Carry Case --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/48187703-celestron-18774-cgl-powertank-7-12v-7ah-black](https://www.desertcart.it/products/48187703-celestron-18774-cgl-powertank-7-12v-7ah-black) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-08*
