STARSEEKER Go50 Portable Coffee Grinder, 50mm Conical Burr

A campsite, an office, a rental kitchen: the coffee you get there is only as good as what you can grind there, which is usually nothing.

A grinder that runs on its own battery and refills from any USB-C source keeps real coffee with you wherever you land, instead of falling back to preground.

• One grinder that travels, not a second one to buy: it runs on a rechargeable battery the manufacturer says can be topped up from a power bank, a car charger, or a laptop, no outlet, no hunting for one.
• Fine enough for espresso: a conical burr set that reaches espresso range, so coffee away from home doesn't default to a coarser method.
• Micro-adjust wherever you land: stepless adjustment means you dial in against the water and beans you actually find there, instead of committing to one setting before you leave.
• Grounds go where you point them: a plasma anti-static system is fitted to keep grounds from clinging and scattering, which matters more, not less, on someone else's counter.

For the person who already knows what good coffee tastes like and refuses to give it up in a hotel room, a van, or a cubicle. If this would be the only grinder in your kitchen and you brew a liter of filter every morning, buy a plugged-in grinder with a hopper instead: a battery and a compact burr set are the wrong tool for volume.

Two purchase options. The grinder on its own, or the set, which the manufacturer describes as adding the Super58 manual espresso maker (58mm portafilter for an 18–20 g dose, two extraction modes, pressure gauge, aluminum body), a folding stand, and a carry case. The manufacturer does not itemize the case contents piece by piece. Email us before ordering if you need the exact packing list.

A note on the voltage line. The manufacturer's spec sheet lists 120V–220V for this listing, while the grinder itself charges over USB-C. We cannot confirm which component that rating refers to, so we are not going to interpret it for you. US household power is 110–120V; if you are buying the set and need mains details for the Super58, ask us and we will get an answer from the supplier first.

Shipping is free on every order. Orders are processed within 1–3 business days and delivered in 6–8 business days.

This grinder runs on a rechargeable battery and charges over USB-C, so there is no plug variant to choose.

Returns are accepted within 30 days of delivery under our Refund Policy. There is no restocking fee. If anything about the condition of your order is wrong on arrival, contact us before doing anything else and we will sort it out with you.

No manufacturer warranty is documented for this model in the information we receive from the supplier. We would rather tell you that than imply coverage that may not exist.

If your unit arrives damaged or fails on arrival, contact us at contact@atelier58coffee.com with photos and we will handle it with the supplier.
