Product Description

The PowerTank Glow 5000 is an essential for any amateur astronomer. This 2-in-1 device features a rechargeable handheld red LED flashlight with three brightness levels and a 5000 mAh 5V DC power bank to charge mobile devices.

The PowerTank Glow 5000 attaches onto one of your telescope tripod legs or other convenient locations using one of the two included silicone straps so it is safe and out of the way. A wrist strap is also included for handheld use.

Perfect astronomy flashlight

A red flashlight is one of the most beneficial accessories you can own as an amateur astronomer, no matter how occasional your night sky observations may be. The PowerTank Glow is the perfect astronomy flashlight as this will not compromise your vision at night with its red LED flashlight. This flashlight has three brightness levels that allows you to adjust the brightness depending on how dark your observing site is. When your flashlight needs power, no need to change out your batteries like traditional flashlights, just recharge the PowerTank Glow.

The perfect power solution for SkyPortal and other planetarium apps

Explore the Solar System with your phone or tablet without draining your battery. With hours of continuous use, planetarium apps like Celestron’s SkyPortal can drain your smartphone’s battery. What’s more, your phone may not be at 100% when you begin observing. Those worries become a thing of the past with PowerTank Glow 5000. This compact power bank delivers a full charge to mobile devices with its 5000 mAh capacity, so you can use your smartphone confidently to scan the skies, capture images through the eyepiece, and share the experience with friends on social media.

High quality lithium battery technology you can trust

The power bank has an output port for charging 5V DC devices, including smartphones and tablets. The input port is used to recharge the internal lithium-ion battery. The battery has a minimum of 500x charge cycles, so it can serve your astronomy needs for years to come. The input/output ports have integrated covers to protect them when they are not in use. The PowerTank Glow 5000 has overcharge protection, so the battery cannot be damaged if inadvertently left recharging for an extended period.

Easy to use in the field

The PowerTank Glow 5000 has a single button that controls all its functions. Short presses of the button turn the red flashlight on, cycle through the three brightness levels starting with the dimmest, and then turn the flashlight off. Pressing and holding the button turns device charging on and off.

The flashlight can be used while the output port is charging an external device. Four red battery indicator LEDs indicate the battery charge status, while a green LED indicates when the PowerTank Glow 5000 is providing power to a device.

12V power

There is no 12V power cable, to connect to my SkyWatcher 35 EQM 35 PRo.

Celestron PowerTank Glow 5000 (93585)

Really nice night flashlight, lasts days on a charge.

Still works great when you power your phone and you can get a couple nights using it as a battery bank and red flashlight.

Very bright Red led settings and at full power is really bright.

Great replacement for my original red flashlight from like 30 years ago!

Superb service from All-Star Teleacope as always!

Good !

Pretty cool

Celestron PowerTank Glow 5000

The light is great, strong distance coverage.
Only thing I don't like is the on/off button can be accidental turned on, its a light touch.


This is a great tool as it has multiple brightness settings, can charge devices, and has straps to attach it for hands free use. One of my favourite features is that it is rechargeable so no need to buy batteries.
