Frequently Asked Questions

Q: Can I adjust the grind size on the URGGU coffee bean grinder while it's grinding?

A: Yes! One of the standout features of this grinder is its 38-gear external adjustment system, which allows you to smoothly switch between coarse and fine grind settings even while the grinder is in operation — giving you full flexibility without stopping the process.

Q: How long does the 2000mAh battery last on a single charge?

A: On a full charge, the URGGU portable grinder is capable of completing 17 or more grinding sessions, making it ideal for daily use at home or on the go. It also supports pass-through charging, so you can plug it in via USB and continue using it while it recharges.

Q: Is the ceramic grinding core better than a metal one?

A: Ceramic grinding cores are heat-resistant and do not transfer excess warmth to your coffee grounds during grinding, which helps preserve the natural aroma and flavour of your beans. The ceramic core in this grinder is rated for up to 8,000 grinding cycles, ensuring long-lasting, consistent performance.

Q: What grind types can I achieve with the 38-gear system?

A: The 38 external adjustment gears cover the full spectrum of grind sizes — from ultra-fine (ideal for espresso) through medium (drip coffee, AeroPress) to coarse (French press, cold brew). This makes the URGGU grinder a versatile choice for virtually any brewing method.
