Cordless Hair Straightener Brush S7

The Hyokyche S7 is a battery-powered straightening brush designed for people who need quick touch-ups away from a power outlet. It suits travellers, commuters and anyone wanting a compact tool that fits in a handbag or carry-on for on-the-go styling.

20-Second Heat-Up and 30-Minute Runtime

The brush reaches working temperature in 20 seconds and holds it across three settings: 160 °C, 180 °C and 200 °C. A full charge delivers up to 30 minutes of continuous use, enough for roughly 34 styling sessions, with consistent heat control when each section is held for 23 seconds.

Type-C Charging and Auto Shut-Off

Charging uses a standard Type-C port compatible with power banks, laptops or in-car ports, so no proprietary adapter is required. The 30-minute automatic shut-off adds safety during travel, while heat-resistant bristles stay cool to the touch. Buyers who need longer runtime for thick or very long hair may find the single-charge limit restrictive.

Questions about this item

How much heat does the 200 °C setting generate during a full 30-minute cordless session?

The brush reaches 200 °C in 20 seconds and holds each section for 23 seconds; the rechargeable battery delivers up to 30 minutes of runtime, enough for about 34 full styling sessions per charge.

What charging equipment do I already need to recharge the built-in battery?

A USB Type-C cable and any standard Type-C power source — laptop, power bank or in-car port — are all that is required; no proprietary adapter is included or needed.

Will the 212-gram brush fit inside the same travel pouch I use for my older corded straightener?

At 7.87 in × 1.77 in × 1.77 in and 212 grams, the cordless S7 is smaller and lighter than most corded models, so it will slip into an existing pouch with room to spare.
