Key Features & Benefits
Type‑C fast charging (modern, universal): 1‑hour charge supports USB power banks, laptops, car chargers and mobile adapters — no need for disposable batteries, more convenient and eco‑friendly.
Long single‑charge use: 300mAh battery gives about 95 minutes per charge—sufficient for multiple family uses.
Bidirectional rotation & 2‑speed control: Low speed (7000 rpm) for sensitive newborn nails; high speed (9500 rpm) for older children/adults. Reverse rotation improves grinding efficiency and prevents nail dust buildup.
LED soft night light: Gentle illumination for precise trimming in dim conditions without harsh glare—perfect for nighttime touch‑ups.
Low noise & low vibration: Engineered for quiet operation so baby’s sleep and comfort are preserved.
Six graded heads: From ultra‑fine to coarse plus a metal/special head—covers newborn (0–3 months) through adult needs.
Ergonomic, portable design: Comfortable grip and pocketable size for travel or diaper bag.
Safe materials & easy maintenance: ABS housing and replaceable heads; heads can be cleaned and replaced as needed.
