## Description

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 : desertcart.in: Electronics

Review: I use this when doing nightscape photography and it does a great job of keeping the dew from forming on my lens. It has low, medium and high settings and so far I’ve only had to use medium. I power it with a usb battery bank. (Not included) Comes with a pouch that’s perfect for storing hit and the battery together.
Review: Astronomy. New to the hobby... and I am so glad these work as well as they do;-) Anyone who stares through a telescope on a winter night would understand. No drama, just plug it in and does the job nicely. Comes with a nice bag (some don't, I have others), has a nice cord that is easy to manage when cold. And the cord has been long enough to work fine for my needs (8"dob with a battery at it's base). I leave it on all night. In the beginning I checked the temperature regularly but now have just settled in to taking it for granted (sigh of relief)

## Questions & Answers

**Q: Does this device have to use the timer? Can it stay on and off without using the timer?   Is the the timer just an additional feature?**
A: You do not need to use a timer with this device.  Additionally, it has three heat settings:  low, medium, and high.

**Q: What's the wattage for each setting hi/med/lo ?**
A: Not sure wattage. I used in sub freezing (20*F) weather on lowest setting and had no fogging/dew on  Nikkor Z20mm 1.8, Nikkor Z70-200 2.8, and a Tokina 14-28 2.8. Works well, surprisingly low cost. (I use a cheaply rechargeable battery bank)

**Q: Recommended power bank that is known to work with this dew heater?**
A: Any that are 2.1 to 2.5 amps

**Q: Does this unit automatically turn off? i need a lens warmer that will last 4-5 days without turning off.**

*by J***Y on 31 October 2023*

The instruction print is a bit small. To turn on hold the button for about two seconds. What's nice: it's long, and it comes in a nice pouch. Con: It may be just me, but I prefer my cables to be modular, this isn't.
