About this item

  • 【Enhanced Heating with FPC Technology】 Designed with FPC (flexible printed circuits), this lightweight yet durable lens heater uses polyimide films as the insulator for reliable dielectric performance, and thermofoil as the heating element for improved thermal conductivity and higher heat transfer efficiency to quickly and evenly warm up your lens. Note: The lens heater is bendable but cannot be folded
  • 【Effective 16"/400mm Heater Length】 Eliminate dew, fog, and condensation with our specially crafted lens warmer during cold weather photography. For optimal performance and even heating, it is recommended to use on lenses or telescopes with a circumference of up to 16"/400mm and a diameter of 127mm
  • 【Safe 5V 2A USB Power Supply】 Through the 6ft/1.8m USB cable, the lens heater can receive power from any USB power source with a 5V 2A output and feature overheating/overvoltage protection for safe use. A regulator offers 3 temperature levels (High: 125.6°F/52°C; Mid: 113°F/45°C; Low: 98.6°F/37°C) for different environments
  • 【Touch Fastener Attachment】 Thanks to the flexibility and thinness of the FPC, the heater can easily wrap around your lens via the touch fastener. Note: The heating area length is 16"/400mm, and the total length is 22"/550mm including the touch fastener
  • 【A Multifunctional Heating Tool】 As a multipurpose heater with a whole length of 22"/550mm (including the fastener part), it can also keep your coffee mug warm in winter (use with care). Can also be used on telescopes, scopes, etc

As a night and nature photographer, this has been a godsend. It’s versatile and easy to use. I plug it into a power bank, which I’ll usually hang from a bag from my tripod or shove in my pocket if I’m handheld. It wraps up small and is easy to store. I’ve used it on several lenses of varying sizes, with and without lens hoods, without issue. It really helps keep the fogging down in cold and damp environments.

Zero stars. They shut off after a few minutes and will not stay on. Useless.
Okay, but problems

寒い季節の夜空撮影。気を抜くとレンズが真っ白に曇って写真が台無し。が度々あり、これはレンズヒーター買わねばと検索したらこちらに出会いました。昔の電池のヒーターは重い割にあまり効かずでしたが、今のレンズヒーターは軽くて使いやすいです。

The heater I originally purchased would not work right out of the box. So I contacted Neewer Customer Service, described the issue, and within a few days there was a replacement on my doorstep.No hassles - I like that!

5V／2.2A／11W（HIGH）使用したい時間÷2.2(A)＝必要なバッテリーの容量温度は「HIGH」で人肌と同じくらい。一定の温度に達すると電流が止まり、温度が下がると電流が流れる。一定の温度を保つことができる。冷えたカメラレンズを温かい室内に入れたときの結露防止になればと思い購入。この製品単体では、このような状況の結露は防げないが、ないよりはマシ。もっと温かい（カイロくらいの温かさ）と、自分の用途には適しているので星－1。製品のベルトの黒い部分、40cmの範囲はすべてが発熱する。縫製は良い。

400 mm fits a 102 nicely with some overlap, a great handy back up if something goes on the main system or as a travel system heater with a battery as extra.Not my first one, My last one made it 1 year using a powered USB hub.Astrophotography is brutal on gear, so that's something to say for this inexpensive heater without the controller cost.
