How good is the LED as a spotlight (how far does it project)?** A: The smaller light is sufficient to see within 30 feet but is not overly bright. The LED is much brighter and useful as a spot and will project well up to about 100 feet. **Q: Is the battery of the PowerTank safe for airplane checked baggage?** A: I see no serious complications. I have never checked a psu in my baggage, but I have checked computer components along with other dry cell batteries. **Q: Can the pack be charged in Europe (220 V)?** A: Hi! I live in Chile, and we use 220 ​​volts. And I have a PowerTank, and i don't have problem with the charge. I hope my comments will serve as a reference. Best regards. **Q: Is there an alternative we can buy since these don't seem to hold up?** A: Not sure what you man by "these don't hold up" because they last years if you take care of them and charge them up once in awhile while not in use. Look for the Power Tank Lithium as an option. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Power Tank. *by A***R on November 18, 2025* Reliable. Has lasted 10 years so far. Works great out in the field. ### ⭐⭐⭐⭐⭐ Nice power tank for my telescope with the 17 amp hour battery *by A***R on September 3, 2024* Like the size, battery capacity of 17 amp hours last a long time and easy to charge with the terminal's on the side. I use my 2 amp motorcycle charger and it works great. Like the red light, keeps the ground so I can see while using my telescope. ### ⭐⭐⭐⭐⭐ A good and versatile product. *by J***T on May 19, 2015* 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. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.ke/products/1928919-powertank-12](https://www.desertcart.co.ke/products/1928919-powertank-12) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-05-18*
