1. How long does the battery last per charge for styling?
The 3500mAh lithium battery provides 45 mins of continuous use (1.5-hour charge time via USB-C), enough for 5-7 full styling sessions. The LED power display prevents unexpected shutdowns.

2. Can this one tool really straighten, curl, and smooth hair?
*Yes, the 3-in-1 rotating ceramic plate works at 160-210°C:

Straighten: 210°C for thick hair
Curl: 180°C with rotating barrel
Smooth: 160°C + 10M negative ions to reduce frizz*

3. Does the negative ion technology really prevent damage?
The built-in negative ion generator (10M/cm³) neutralizes static and seals hair cuticles, reducing breakage by 30% vs. traditional heat tools (tested at 185°C on bleached hair).
