FAQ

Before you buy.

Can the T38 Plus grind fine enough for espresso?

Yes, absolutely. The Geimori T38 Plus features a high-precision stainless steel conical burr. We recommend settings 0-15 for Espresso. It can grind fine enough for both unpressurized and pressurized portafilters, delivering rich crema.

Is T38 Plus battery powered?

No. T38 Plus uses an AC–DC adapter for stable plug-in power and requires a wall outlet.

Can I use it with 220–240 V power?

Yes. The T38 Plus comes with a global voltage adapter (100-240V). You can use it safely in the US, Europe, Asia, or anywhere else worldwide without a voltage converter. It is the perfect travel companion for coffee lovers. A destination-appropriate plug head may still be required.

How should I reduce retained grounds?

The straight-through design minimizes retention naturally. For the best results, we recommend two simple pro tips: 1) Use the "RDT" to eliminate static, and 2) Press the hopper bellows at the end of the grind to purge any remaining particles.

Is the grinder noisy?

It is whisper-quiet (< 60dB). Thanks to the high-torque, low-speed motor, it runs much quieter than blade grinders or high-speed burr grinders. It's perfect for early mornings, offices, or camping without disturbing others.
