Geimori T38 Portable Coffee Grinder

Geimori T38 Portable Coffee Grinder
38mm 6-Axis Conical Burrs | 3600mAh Rechargeable Battery | 80+ Doses Per Charge | Stepless Adjustment | Zero Retention | All-Metal + Walnut Build

Café-quality grinding. No outlet required.

The T38 is the grinder for the coffee standard that doesn't stay home. Where the T38 Plus brings the same 38mm conical burr performance to a plug-in countertop format, the T38 takes it fully cordless — a 3600mAh rechargeable battery, USB-C fast charging to full in 1.5 hours, and 80+ doses per charge that covers a week of camping, a month of office mornings, or a daily home routine without a power outlet factoring into the equation at all. The freedom is genuine, and the performance that comes with it is not the kind most cordless grinders can offer.

The 38mm 6-axis conical burrs are CNC-machined from high-nitrogen stainless steel at HRC58 hardness — the same burr geometry and material specification as the T38 Plus, built for the even bean feeding and consistent particle distribution that espresso extraction demands and every other brew method benefits from. The 0.01mm stepless adjustment covers the full range from fine espresso to coarse French press with the precision that fixed-step grinders can only approximate. Low-RPM grinding keeps heat transfer minimal and operating noise below 60 dBA — the grinding speed that preserves delicate aromatics rather than processing them away in the interest of throughput.

The straight-through grinding path keeps retention minimal by design, and the included bellows purge the remaining particles at the end of each dose. The anti-static technology keeps grounds contained rather than scattered across whatever surface the grinder is sitting on — which, for a grinder that travels, covers a wider range of surfaces than most. The magnetic dosing cup snaps on and auto-aligns for a clean, contained workflow wherever the dose is going. Tool-free burr removal makes cleaning fast enough to do consistently, whether the grinder is at home or on a trail.

The all-metal aluminum alloy body with walnut wood accents is built without plastic — a material choice that reflects both durability and the environmental intention that runs through the T38's design. At 101x66x180mm and 900g, it fits in a backpack, a suitcase, a kitchen drawer, or a palm — proportioned for portability without feeling provisional.

Native Manor Note: The difference between the T38 and the T38 Plus is a single but meaningful one: the battery. The T38 Plus plugs in — fast, capable, and compact for the kitchen or the hotel room with an outlet nearby. The T38 needs nothing. A 3600mAh battery rated for 5+ years of daily use, USB-C charging that restores it fully in 1.5 hours, and 80+ doses per charge that makes the question of power availability irrelevant for most real-world travel scenarios. The same 38mm 6-axis conical burrs, the same stepless precision, the same all-metal and walnut construction — in the format that goes wherever the coffee needs to go, without a cord determining where that is.
