Timemore Nano Grinder: The Tiny Hand Grinder That Punches Above Its Size

The Timemore Nano is one of the smallest hand coffee grinders you can buy. It's designed for travel, camping, and anyone who wants to grind fresh coffee without carrying a full-sized grinder. At about the size of a Red Bull can, it fits in a jacket pocket or a small bag compartment. If you're looking at the Nano, you probably want to know whether something this tiny can actually produce a decent grind. The answer is yes, with a few caveats.

I bought a Timemore Nano specifically for travel and have taken it on about a dozen trips over the past year. Here's my honest review covering grind quality, capacity, build, and how it compares to other portable options.

What You Get in the Box

The Timemore Nano comes in minimal packaging:

  • The grinder itself (body, burr assembly, handle, cap)
  • A carrying pouch
  • A small cleaning brush

That's it. No instructions beyond a basic diagram, but the grinder is simple enough that you don't really need them. The body unscrews in the middle to access the burr assembly, and the grind adjustment is done by turning a numbered dial at the bottom of the burr shaft.

Build and Materials

The Nano uses a combination of aluminum alloy for the outer body and stainless steel for the burr assembly. The handle folds flat against the body for storage. The entire unit weighs about 350 grams (12 ounces), which is light enough that you barely notice it in a bag.

The build quality is good for the price ($60 to $80). It doesn't feel as premium as a Comandante C40 or 1Zpresso K-Max, but it also costs less than half what those grinders cost. The aluminum body has a smooth matte finish that resists scratches reasonably well.

Grind Quality

The Burrs

The Nano uses Timemore's E&B (Espresso and Brew) burr set. These are 38mm stainless steel conical burrs. For reference, most full-sized hand grinders use 38mm to 48mm burrs, so the Nano isn't compromising on burr diameter despite its smaller overall size.

The E&B burrs are designed to work across a wide grind range, from espresso fine to French press coarse. In practice, the Nano performs best in the medium to coarse range (pour-over, AeroPress, French press). It can grind fine enough for espresso, but the smaller capacity and longer grind time make it impractical for that purpose.

My Testing Results

I tested the Nano across three brew methods:

Pour-over (V60): - Grind setting: about 15 to 18 clicks from closed - Results: Clean, even extraction with good sweetness - Comparable to my 1Zpresso JX at a similar setting - This is the Nano's sweet spot

AeroPress: - Grind setting: about 10 to 14 clicks from closed - Results: Smooth, balanced cup. The slightly wider particle distribution from the small burrs actually works well with AeroPress's immersion brewing - My go-to travel setup: Nano + AeroPress + insulated mug

French press: - Grind setting: about 22 to 26 clicks from closed - Results: Acceptable but not amazing. Some fines make it through at coarser settings, leading to slight siltiness - Still much better than pre-ground coffee

Espresso: - Grind setting: about 6 to 8 clicks from closed - Results: It works, but grinding 18 grams takes over 2 minutes and gives your hand a real workout. The grind is fine enough for a pressurized portafilter but may not satisfy unpressurized basket users - Not recommended as a daily espresso grinder

Capacity and Grinding Speed

The Nano holds about 15 to 18 grams of beans depending on the roast level (darker roasts are less dense and take more volume). That's enough for one large cup of pour-over or AeroPress, or one small French press serving.

Grinding time at a medium setting:

  • 15 grams: About 50 to 60 seconds
  • 18 grams: About 70 to 80 seconds

This is slower than full-sized hand grinders like the Comandante (30 to 40 seconds for 18 grams) because the Nano's smaller body gives you less leverage. Your hand and forearm will feel it if you grind more than two doses in a row.

The short handle is the main culprit. Full-sized grinders have longer handles that create more torque with less effort. The Nano's folding handle sacrifices leverage for portability. Fair tradeoff for travel, but you wouldn't want this as your only grinder.

Travel Performance

This is where the Nano truly excels. I've packed it for:

  • Weekend camping trips (paired with an AeroPress and a kettle)
  • Business travel (hotel room coffee that doesn't taste like sadness)
  • Day hikes (Nano + AeroPress Go + thermos of hot water)
  • Visiting family who only have pre-ground Folgers

The compact size means it fits places other grinders can't:

  • Carry-on luggage (never had issues with TSA)
  • Jacket pocket
  • Glove compartment
  • Small daypack side pocket

One tip: I keep a few doses of beans in a small ziplock bag alongside the Nano in its pouch. That way I have everything I need for a fresh cup without digging through my bag for a separate bean container.

Nano vs. Other Travel Grinders

Nano vs. 1Zpresso Q2

The 1Zpresso Q2 is the Nano's closest competitor. Both are compact, both cost $60 to $80, and both target the travel market.

  • Grind quality: Very similar. The Q2's burrs are slightly more refined at espresso-fine settings, but for filter coffee they're neck and neck.
  • Build: The Q2 has a slightly more premium feel with its aluminum body. The Nano's folding handle is more portable.
  • Capacity: Both hold about 15 to 18 grams.
  • Adjustment: The Nano's external numbered dial is easier to read than the Q2's internal adjustment.

If portability is your top priority, the Nano wins because of the folding handle. If grind quality at finer settings matters more, the Q2 has a slight edge.

Nano vs. Comandante C40

This isn't really a fair comparison since the Comandante costs $250+, but I get asked about it. The Comandante is a full-sized hand grinder that produces noticeably better grind quality, especially at espresso settings. It's also faster to grind due to the longer handle. But it's three times the size and four times the price. If you're traveling light, the Nano is the obvious choice.

Nano vs. Porlex Mini

The Porlex Mini ($60) is an older travel grinder that the Nano has largely replaced in the market. The Nano has better burrs, better build quality, and a more precise adjustment mechanism. Unless you find a Porlex at a steep discount, the Nano is the better buy.

Maintenance

The Nano is simple to maintain:

After Each Use

  • Tap the grinder upside down to knock out loose grounds
  • Use the included brush to sweep the burr area
  • Blow into the opening to clear fine particles

Monthly

  • Disassemble the grinder completely (unscrew the body, remove the burr assembly)
  • Brush all surfaces with a dry brush
  • Wipe the burrs with a dry cloth (never use water on the burrs)
  • Inspect the burrs for any chips or damage
  • Reassemble and test the grind adjustment

Yearly

  • Check the burr alignment
  • Replace the bearing if grinding starts feeling rough or gritty
  • Consider replacing the burrs if you grind daily (they should last 2 to 3 years with regular use)

FAQ

Is the Timemore Nano good for espresso?

It can produce a fine enough grind for espresso, but the small capacity (15 to 18 grams) and long grind time (2+ minutes at espresso fineness) make it impractical for daily espresso use. It works in a pinch, especially with a pressurized portafilter, but I wouldn't buy it specifically for espresso.

How many cups can the Timemore Nano make per fill?

One cup. The capacity is about 15 to 18 grams, which is enough for a single pour-over, AeroPress, or small French press. For multiple cups, you'll need to refill and grind again.

Can I take the Timemore Nano on a plane?

Yes. I've taken mine through TSA multiple times without any issues. Coffee grinders are not restricted items. The compact size fits easily in carry-on luggage.

How does the Timemore Nano compare to the Timemore C2?

The C2 is Timemore's full-sized budget hand grinder. It has the same E&B burrs but a larger body, longer handle, and 25-gram capacity. The C2 is faster and easier to grind with. The Nano is smaller and more portable. If you don't need the compact size, the C2 is the better value at a similar price.

Is the Nano Right for You?

The Timemore Nano is a purpose-built travel grinder, and it does that job really well. If you travel frequently and refuse to drink hotel coffee or pre-ground beans, the Nano gives you genuinely fresh grinds in a package that fits almost anywhere. It's not a replacement for a full-sized home grinder, and it's not ideal for espresso. But for pour-over, AeroPress, and French press on the go, it's one of the best compact options available. Pair it with your favorite travel brewer, pack some good beans, and you'll have better coffee than 95% of the places you visit.
