AAOBOSI Electric Conical Burr Coffee Grinder, Grind by Weight, 60 Settings | Cordless, Auto-Stop Dosing 6-30g, 200 RPM Low-Speed Grind, USB-C, 130g Hopper, Espresso to French Press, Office Camping

The AAOBOSI Electric Conical Burr Grinder combines portability with precision dosing—a rare combination for home brewers who want consistency without being tethered to an outlet. Whether you're dialing in espresso at home, brewing pour-over at the office, or grinding beans in an RV, this cordless grinder handles the fundamentals: accurate weight-based dosing, a conical burr that grinds evenly, and enough battery life for multiple cups per charge.

Dosing by Weight, Not Guesswork

The built-in scale removes a common friction point in coffee preparation. You set your target dose between 6 and 30 grams in 0.1-gram increments, and the grinder auto-stops when it reaches your weight with ±0.3-gram accuracy. This means you can dial in 18 grams for espresso or 30 grams for a large pour-over without fumbling with a separate kitchen scale or pre-weighing beans.

  • Real-time weight display during grinding
  • Auto-stop at target dose or when hopper empties
  • No external scale required for repeatable results

Conical Burr Design and Grind Range

A 40-millimeter SUS420 stainless steel conical burr operates at a modest 200 RPM—low enough to avoid heat buildup and the friction that can damage bean oils. This conservative speed helps preserve flavor and aroma compared to faster burr grinders. The grind settings span 60 main positions plus 5 extra-fine backup positions, covering the spectrum from fine espresso to coarse French press.

  • Conical burr reduces heat and friction during grinding
  • 60 main settings with 5 ultra-fine backup positions
  • Suitable for espresso, pour-over, drip, and immersion brewing

Cordless Convenience and Practical Features

A 2600-mAh battery charges via USB-C and enables 25 to 35 doses on a full charge (measured at 18 grams per dose on setting 5). The grinder can continue operating while plugged in, so you're never forced to stop mid-session. A silicone bellows purge mechanism blows residual grounds from the chamber after each use, reducing retention and cross-contamination when switching between beans or brew methods. The 130-gram hopper and up-to-60-gram grounds chamber allow you to load beans once and dose multiple cups consecutively.

  • USB-C charging with ability to grind while plugged in
  • Bellows purge reduces ground retention between beans
  • Portafilter cradle included; stainless steel cup for other brew methods
  • Compact footprint: 9.6 x 4.3 x 12.4 inches

The AAOBOSI grinder is designed for people who value consistency and flexibility over counter space. Its weight-based dosing removes variables that many home brewers struggle with, and the cordless format genuinely suits mobile coffee preparation. The conical burr and low-speed grind suggest attention to preserving bean quality, though your results will ultimately depend on dialing in grind size for your specific brew method and bean origin.
