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. ## 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.jp/products/1928919-powertank-12v-rechargeable-telescope-battery-pack-84-wh](https://www.desertcart.jp/products/1928919-powertank-12v-rechargeable-telescope-battery-pack-84-wh) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-21*
