Celestron PowerTank Glow 5000
The Ultimate Night Vision-Friendly Flashlight and Power Bank for Astronomy
If you’ve ever found yourself fumbling with dim red flashlights or watching your phone battery dwindle while running your favorite star app, the Celestron PowerTank Glow 5000 is about to make your nights a whole lot easier. This 2-in-1 essential combines a rechargeable red LED flashlight with a high-capacity USB power bank, making it a must-have accessory for any observer—casual or committed.
Designed specifically for astronomy, the PowerTank Glow 5000 slips onto your tripod leg, tucks into your pocket, or hangs from your wrist, ready to illuminate your charts and charge your gear without ruining your night vision.
Preserve Your Dark Adaptation—Without Sacrificing Functionality
Unlike white LED flashlights that ruin your hard-earned dark adaptation, the PowerTank Glow’s red LED beam keeps your vision tuned to the night sky. It offers three brightness levels, so you can match your light output to your observing site’s darkness. Need to read your star chart, check a focuser, or just not trip over your tripod leg? The Glow has you covered—without turning your observing neighbors into light pollution victims.
When it’s time to recharge, just plug the PowerTank into a USB port. No battery swaps, no fiddling in the dark—just plug and go.
Keep Your Phone Powered for Star Hopping and Sharing
Whether you’re running planetarium apps like Celestron’s SkyPortal, capturing photos through the eyepiece, or texting friends about that incredible view of Jupiter, astronomy can drain your phone battery fast. The Glow 5000’s 5000 mAh internal battery delivers a full smartphone recharge through its USB Type-A 5V/1A output port, keeping your device online all night long.
And yes, the flashlight works while charging another device, so you don’t have to choose between power and visibility.
Field-Ready Design
The PowerTank Glow 5000 is built for real-world observing. Its slim cylindrical body is just 5.5 inches long and 1.3 inches in diameter, weighing less than half a pound. A wrist strap is included for handheld use, along with two silicone straps that let you securely mount it to your tripod leg, eyepiece tray, or gear case handle. Keep it within reach and out of the way—exactly where you need it.
The flashlight’s single-button control keeps operation intuitive, even with gloves on. Tap to cycle through brightness levels; press and hold to activate or deactivate device charging. Four small red LEDs show battery status, and a green LED confirms when it’s powering a device.
Reliable Power You Can Count On
The PowerTank Glow uses a rechargeable lithium-ion battery rated for 500+ cycles and includes built-in overcharge protection. Weather-sealed to IP65 standards, it shrugs off dust, dew, and the occasional knock. It charges fully in about 3.5 hours, so you can top it off during the day and know it’s ready when the Sun sets.
Observing Tip:
Mount the PowerTank Glow 5000 to your tripod leg using the included silicone strap and set the light to its lowest brightness level. You’ll have enough illumination to see your setup without compromising your vision or annoying your observing companions.
Final Thoughts
Whether you're planning an all-night session under the stars or just want a reliable backup light and charger for your grab-and-go rig, the Celestron PowerTank Glow 5000 is one of the best-value accessories in amateur astronomy. Thoughtful, rugged, and purpose-built for dark sky observing—it’s a red light you’ll actually look forward to seeing.
