Cordless/rechargeable hair tool recommendations

About to go on a long vanlife expedition but still wanna look cute when I can!

Does anyone have any recommendations for rechargeable hair tools?

Ideally wanting a heated round brush but I’m open to straighteners/curlers if people have personal experience with them and can recommend.

Tried ordering the Lady Jayne Volumising brush because it was on sale at Chemist Warehouse but they’ve just emailed to say I’ve been refunded because it’s out of stock :((
