Looking for a cordless mini straightener for bangs (travel/festival)

Hey!

I'm looking for a cordless mini hair straightener that I can use on my bangs.

I already have a regular straightener that I really like, so this one would only be for travel (mostly festivals, so no access to electricity). Because of that:

• It has to be cordless
• Battery should last at least a couple of days with light use (I only straighten my bangs, so it takes like a couple of minutes max)
• It doesn't need super high heat. My hair is already pretty straight, just slightly wavy
• Prefer something not too expensive since I'm only going to use it a couple of times a year

I'm mostly looking for something small, easy to carry, and reliable rather than super powerful. I've been trying to look around myself, but it's kind of hard to tell what's actually good vs just looks good online, especially when it comes to battery life.

Would really appreciate any recommendations or real experiences!
