For simplicity, I would be thinking of a pot of water on the fire. Lol. It would help if we knew how much stuff you were taking camping. Cooking over a fire or do you have gas? I’m sure you’ve sorted it

First place to look would be a camping store. Next I would check on eBay. I didn’t go camping with a bottle fed baby so I’ve never used any

if you are camping you could just simply get a container of warm water and put the bottle in it

have you tried the heat packs they not only good for aches n pains but require no batteries and when you finish you just boil it back up and press when needed

We had one that just plugged into the car it was fantastic. I cannot tell you what is was though as that was years ago.

there are some good comments here

I would ask at your local camping shop, they have little gas kettles, otherwise could you make it with warm water from a thermos?

maybe look online like ebay and things

Hope you managed to find one.

Checking out what the really big camping stores have is a good idea, eg Anaconda.

what did you end up with? i didnt even know these things existed

check out the camping and baby shops as they might have some good ones too

how did you go? 🙂

the snap and go sounds like a fantastic option

Did you find one that was suitable.

What did you end up getting?

What did you end up buying?

I hope that you have found one

Great advice here, I hope you found one!

Hope you were able to source one
