You can use power bank though **Q: What size voltage power bank do you need?** A: Whatever the voltage is on a USB battery, I believe about 5 V **Q: Does this dew heater work with a Nikon 55-200mm kit lens? Sorry if this is a dumb question** A: This lens warmer works with any size lens that the wrap can fit around. I use it for a 61 mm telescope, and there’s plenty of spare wrap to accommodate a larger lens. I had a 55 to 200 and it was similar diameter to my telescope It is also effective to stave off, frost and condensation as long as use the wrap right along the plane of the lens area. I keep the setting also on high during the coldest nights of winter to discourage condensation. **Q: What is the device's power consumption? How long will it stay warm with a 10,000 mAhr power bank?** A: I plug mine into a 33,800 mA hour battery and I believe it will last most all night. So I imagine 10,000 mA hours will last at least 3 to 4 hours if not more. If the setting is on low it would last longer; there are three settings, low, medium, high. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Keeps dew from forming *by T***A on December 21, 2024* Works as expected, keeps dew from forming on lens. ### ⭐⭐⭐⭐⭐ It works and works well......what else is there? *by S***E on December 14, 2022* alright, this is used for 2 inch eye pieces on a telescope and my canon lenses. For anyone who has used the telescopes at night, or done photography in cold weather, you know that foggy or misty lense.......drives you to drink!! This will be a bit big for the smaller eye pieces, but the 2 incher's are just fine. For 90% of standard lenses you will be good also. For me, the usb power supply meshes very well with the adapter I have that turns my Dewalt 20v batteries, into power sources for these warmers. And they work!!! If they can handle the Michigan Winters, they should be able to handle most of what can be thrown at them. Power draw is moderate, allowing me to power 2 of these, from a 5h battery, for several nights, viewing 3-5 hours per night. For me, this is a no-brainer ### ⭐⭐⭐⭐ Big and gets the job done. *by A***R on December 18, 2021* This lens warmer definitely gets the job done but I wish there was an indicator light to show when it's powered on. This is more of an issue on my end, but I have a rather small USB battery bank I take with me so the warmer works great when it has enough juice but went the battery gets low it warms less and less until it doesn't do anything anymore. It would be nice it have an indicator to see if its still running.I've got a 80mm cassegrain that would fog over in about 15 minutes if not for the warmer. With my tiny power bank I can get like 45 minutes before having to worry about that. ## Frequently Bought Together - Lens Warmer,LOSHARP Dew Heater for Telescope Lens Heating defogging and dehumidification, 3 Gear Regulator Temperature 　for Telescope Camera Upgrade Version/with Control Switch - Lens Warmer with Cold Flexible Cable Down to -25℃, 350mm Dew Heater Strip Prevents Lens from Dew, Fog and Condensation for Astrophotography, Lens Heater Compatible w/ Telescope and Camera in 4.26" - USB Lens Warmer, Lens Dew Heater Strip with Temperature Regulator, Condensation Prevention for Telescopes Camera DSLR Lens Telescope Eyepieces Less Than 3.15 inch (80mm) in Diameter --- ## 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.is/products/358546968-usb-powered-lens-warmer-dew-heater-for-telescope-camera-3](https://www.desertcart.is/products/358546968-usb-powered-lens-warmer-dew-heater-for-telescope-camera-3) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-14*
