#1 KYO Steri Warmer

This Onahole warmer from KYO has 6 UV lights along the stick shaft that both heat and kill 99% of all germs. It comes with English instructions which none of the other products on this list has.

You have to have your own power brick or a device with a USB port to use it.

There is also a self-turn-off function in the KYO heater so you don’t damage anything if you forget it plugged in.

What I like about it:

  • It heats and disinfects my Onaholes in a few minutes
  • The tiny base makes it usable with sex dolls and masturbators with legs
  • USB powered
  • Very easy to clean
  • English instructions
  • Fairly cheap for the features you’re getting

What I don’t like about it:

  • A large base would have been nice for smaller Onaholes
  • Only 5 inches long

KYO Warmer Final Conclusion

I love this product because it’s so effective both in terms of heating capacity and sterilization features. It does cost a bit more than some of the unknown brands but the quality is certainly there to support the little bump in price.

It’s a good idea to put a bit of water-based lube on the stick before inserting it, this will prevent damaging the entrance of your masturbator.

Overall, a fantastic product that works well for sex dolls, Onaholes, and pocket pussies.

 I recommend the KYO Steri Warmer if you’re after the best warmer on the market right now.

#2 Onahole Warmer Final Edition

The Final Edition Onahole Warmer has a large base which also contains a heating element. This is one of the biggest differences between this and the cheaper stick warmers that only heat the hole.

It has a heating time of just 8:30 minutes and you can always do another heating cycle if you have a very big and thick Onahole.

It has a self-turnoff feature after 1 hour to prevent damage to your Onahole and/or other items near it.

All you have to do is plug in the included USB cable put your Onahole over the heater stick and let it do its thing. You’re ready to enjoy your warm Onahole in less than 10 minutes.

This is what I like:

  • Very effective Onahole warmer
  • The base heats the entire front part
  • Heat your Onahole vertically so it doesn’t stick
  • USB powered
  • Easy to clean and use


  • Not ideal for Onahips because of the large base
  • The instructions are only in Japanese

Onahole Warmer Final Edition Conclusion

The name suggests that it’s the final edition which would be a shame, since all products can be improved.

This is by far the most expensive Onahole warmer that I own, but the price is still low and should not scare many users away.

I love that it heats the entire Onahole and not just the inside. Hitting a cold spot with your cock when you penetrate your Onahole can be quite a mood breaker.

I recommend the Onahole Warmer Final Edition if you want a warmer with a large base.

#3 Earth Stick

Okay, I have to admit that I’ve not tested this one out since it’s not even available yet, but it looks super cool and unique.

It’s a dual stick warmer and moisture absorber that you simply put in your Onahole once you’re done cleaning it. This will leave it completely dry inside and ready for the next masturbation session.

I hate waiting for my sex toys to dry so I can store them away, so this is a real game-changer. I’m looking forward to testing this thing out once it is available.

You can preorder the Onahole Warmer and Diatomaceous Earth Stick Set on Kanojotoys.

Update: It’s sold out 🙁

#4 Men’s Max UV Stick Warmer

This is a new kind of Onahole heater that also uses UV to disinfect while it heats your Onahole.

It will heat it to a nice warm temperature in just 5 minutes and a green indicator light will turn on when it’s ready.

This is what I like:

  • Very fast Onahole heater
  • Uses disinfecting UV light
  • High-quality build
  • USB powered
  • Easy to use and clean


  • Does not heat the Onahole entrance area
  • Cost twice as much as other stick heaters

Men’s Max UV Stick Warmer Conclusion

This is such a nice stick warmer for Onaholes that has included a UV light to also disinfect while it heats it. It’s also perfect for sex doll users who have a hard time cleaning their sex dolls after each use.

Another great thing is the size that allows it to heat even the deepest Onahole you could have.

I recommend the Men’s Max UV Stick warmer if you want an effective and smart way to heat your Onaholes.

Are there other ways to warm up my Onahole?

I’ve used the warm water methods before I got a dedicated Onahole warmer and it works okay. I just found that I had to refill with warm water after 10 minutes and it only really got warm inside after being submerged in warm water for around 20 minutes.

One downside to using warm water to heat your Onahole is that it becomes even more sticky after use. This is because TPE, as most Onaholes are made of, is a porous material that absorbs a small amount of water.

Always Use a Little Lube

It’s very important to use a little bit of water-based lube on the heating stick before inserting it into the masturbator that you wish to heat.

Forcing it in without will pull the fragile TPE material inwards and damage it. You might get away with it a few times but micro tears in the Onahole will only get bigger until it breaks.

Final Thought on Onahole Warmers

I’ve seen a great number of new products that aim to improve your masturbation experience and an Onahole preheater is one of them.

I’ve tested some of the early versions here on Kinkycow, but none worked for long and were a real fire hazard.

You have other options to preheat it but the price of a good Onahole warmer is just $20 and it’s so much better.

If you’re into high-end Onaholes like the Meiki Onaholes then it’s a must-have.

I highly recommend the KYO Steri Warmer if you’re after the best all-around heater right now.
