Description
Coffee starts losing its aroma minutes after it is ground, which is why the hotel room, the office kitchen and the campsite are where good beans go to waste.
This grinder runs on a charge instead of a wall outlet, so whole beans travel with you and get ground the moment you want a cup.
- Fresh grounds with no outlet in sight: it charges over USB and runs on its own 1800 mAh battery, in a Denver hotel or a Tokyo rental.
- Burrs, not blades: a blade chops beans to whatever size it happens to hit, and uneven particles are where the bitter-and-sour-at-once cup comes from; the stainless burr core grinds to the size you set.
- One grinder across your methods: an adjustable scale from coarse to fine covers pour-over, French press and cold brew.
- The travel alternative is usually your arm: a 20 W motor does the grinding a hand mill asks you to crank, in a chamber sized for one or two cups.
Who this is for
A good fit if you already buy whole beans and brew a cup or two by pour-over, French press or cold brew, at a desk, in a camper, or anywhere without a free outlet. Look elsewhere if you pull espresso, because the manufacturer publishes no espresso grind range here and we will not imply one; if you brew for three or more, since the chamber means refilling and regrinding; or if it will never actually leave the counter, because part of this price is portability.

Shipping & Returns

Where good beans usually go to waste
Coffee starts losing its aroma within minutes of being ground. The hotel room, the office kitchen and the campsite are exactly the places where you fall back on something pre-ground, because there is no grinder and no free outlet.
This one runs on its own battery and refills over USB, from a power bank, a car, a laptop. Whole beans travel with you and get ground the moment you want a cup.
Not an espresso grinder
The manufacturer publishes no espresso grind range for this model, so we will not imply one. If you pull shots, look at our espresso grinders instead.
The chamber holds enough for one or two cups. Brewing for three or more means refilling and regrinding.
And if it will never actually leave your counter, buy a plugged-in grinder: part of what you pay for here is portability.
Frequently asked questions
Start with the brew method, not the spec sheet. Espresso needs a fine, repeatable grind and rewards flat burrs or a stepless conical. Pour-over, drip and French press run coarser and are far more forgiving, so a stepped conical covers all three.
If you are unsure, email us with how you brew and which machine you use. We will tell you whether a grinder fits — and if it does not, which one does.
Orders are processed within 1–3 business days and delivered in 6–8 business days after that.
The window is stated before you pay rather than after. If yours passes, email us and we will chase it rather than wait for you to ask twice.
US orders ship with the US plug variant. Where a manufacturer does not publish a voltage or plug type, we say so in the Shipping & Returns section above instead of assuming — and you can email us and we will get it from the supplier in writing before you buy.
Contact us first, with photos or a short video. We take it up with the supplier on your behalf and arrange a replacement or a refund.
Reach us before opening a payment dispute — it is faster, and we would rather fix it than argue about it.
Yes. Returns are accepted within 30 days of delivery under our Refund Policy. Contact us before sending anything back — returns received without notice take considerably longer to process.
Not yet as catalogue items. If you need a burr set or a spare for a grinder you bought from us, email us and we will source it from the supplier and quote you.
We would rather tell you that than list parts we cannot reliably ship.
