TimeMore Whirly 01S Portable Electric Grinder
The Whirly 01S Portable Electric Grinder combines functionality with portability for coffee drinkers who need consistent grinding performance in mobile settings. Its compact design works well for travel and small spaces while maintaining grinding precision.
The grinder features a 42mm S2C burr set that produces uniform grounds, enabling better flavour extraction across brew methods. Users can adjust grind settings for different preparations, from pour-over to French press. The rechargeable battery supports cordless operation, making the grinder practical for use outside traditional kitchen environments.
For ease of use, the Whirly 01S features a single-button control system and operates with relatively quiet performance. The retractable hopper design minimises popcorning and reduces the grinder’s storage footprint. A 40g plastic catch cup fits standard 58mm portafilter baskets for direct transfer of grounds.
Constructed with matte black aluminium, the grinder offers durability in a portable form factor. These features make the Whirly 01S suitable for travellers, small kitchens, and coffee enthusiasts who value both performance and space efficiency.

Can It Do Espresso?
Yes, but with caveats:
- The S2C burrs and 0.025mm adjustments enable espresso-fine grinding, but some users may find the steps slightly limiting for ultra-precise tuning (e.g., flow rate adjustments).
- Tested performance: ~90 seconds for 18g espresso grind, producing “syrupy” shots.
- Not for heavy use: While capable, it’s designed for occasional espresso rather than high-volume grinding. So Domestic use

- Cleaning: Disassemble and clean burrs and hopper regularly with a soft brush.
