The facts from the product FAQ and the box — nothing more.
- Charging: over USB-C with the included USB Type-A to Type-C cable, from a USB power adapter or a computer port. While it charges, the battery-level lights flash in sequence; all lit means full.
- Use while charging: no. Charge it before use and do not run it while it is plugged in; SABRENT's manual advises against it for safety and battery life.
- Auto-shutoff: smart power management switches the BLOWZER X6 off after 3 minutes of inactivity, and it shuts itself down if it overheats.
- Battery: 4000 mAh, built in, not user-replaceable. Battery life depends on the mode — Gentle uses the least power, Blowzer Mode the most. The battery-level lights show what is left, each about a quarter of the charge; when all of them flash it is time to recharge.
- Modes: Gentle 40,000 RPM · Boost 80,000 RPM · Blowzer Mode 130,000 RPM, one button; blue LEDs show the mode.
Designing a charging dock? The USB-C port sits in the grip's end cap; the mounts in the MODS library keep a slot and an underside cable channel so the unit charges while docked — the exact position is in the reference pack's DIMENSIONS.md.
