Frequently Asked Questions

FAQs

Is this really an electric burr grinder at this size?

Yes. It uses genuine 420 stainless steel conical burrs — the same material used in professional hand grinders.

The electric motor does the work; the burrs do the precision.

I have a ZenithShot Elite. What grind setting should I use?

Start at click 10. We don't recommend going finer than that. Anything below click 10 can choke the extraction.

If your shot pulls too fast, adjust one click finer at a time until you find your sweet spot.

How many grinds do I get per charge?

Over 13 full grinding sessions on a single charge; enough for a full week of daily brewing.

Exact count varies with grind fineness and bean density (light roasts require more energy), but you won't need to think about charging during a long weekend trip.

What does the twist-expand mechanism actually do?

In compact mode (14cm), the grinder is pocket-sized and ready to toss in your bag.

When you're ready to grind, twist the bottom section and it extends to 19cm, creating a dedicated chamber where your grounds collect — clean, separated, and ready to pour directly into your brewer.

When you're done, twist it back and it collapses to travel size.

Can it grind fine enough for espresso?

Absolutely. The grind range starts at click 6, which produces a fine espresso-grade grind.

With 64 total settings, you can micro-adjust to dial in your exact shot.

How do I clean it?

The twist-expand design means grounds collect in a separate chamber — not packed around the burrs.

Disassembly is tool-free, and a quick brush clears retained grounds in seconds.

Can I take it on an airplane?

Yes — in your carry-on bag. The TSA and FAA permit coffee grinders and small battery-powered electronics in carry-on luggage.

The built-in 800 mAh lithium-ion battery is well within the FAA's 100 Wh carry-on limit. However, per current FAA and airline regulations, we recommend always packing it in your carry-on rather than checked luggage, as most airlines now require or strongly recommend lithium battery devices travel in the cabin.

How long does it take to charge?

The 800 mAh battery charges via USB-C — the same cable you already carry for your phone. A full charge takes approximately 1–2 hours depending on the power source.
