Main trade-off
TIMEMORE C5 Pro
Its 640 g body adds weight, and the 25 g cup is smaller than the chamber.
Head-to-head
TIMEMORE C5 Pro vs 1Zpresso Q Air: A 24 g brew fits C5’s cup but exceeds Q Air’s capacity
The short answer
Choose C5 Pro for a larger single filter brew and a folding handle. Choose Q Air for a lighter kit and smaller doses. At an assumed 60 g/L, a 400 ml brew needs 24 g: that fits the C5’s 25 g cup but exceeds the Q Air’s 15–20 g capacity.
Before you choose
The reasoning and the trade-offs
The size of your mug can matter more than the number of drinkers
One person filling a 400 ml travel mug at 60 g/L needs 24 g of coffee. That fits the C5 Pro’s 25 g cup but exceeds even the Q Air’s 20 g upper capacity, so the smaller grinder needs a split load. A 250 ml cup needs 15 g and fits both published ratings. These are recipe examples using brew-water volume. Your preferred strength and bean density can change the result.
What this is based on
TIMEMORE C5 Pro: 25 g catch capacity. 0.4 L × 60 g/L = 24 g. 1Zpresso Q Air: 15–20 g stated capacity. 0.25 L × 60 g/L = 15 g.
Main trade-off
1Zpresso Q Air
A large solo brew can already need two loads, and the optional case is not included.

What matters in practice
The differences that matter
The size of your mug can matter more than the number of drinkers
One person filling a 400 ml travel mug at 60 g/L needs 24 g of coffee. That fits the C5 Pro’s 25 g cup but exceeds even the Q Air’s 20 g upper capacity, so the smaller grinder needs a split load. A 250 ml cup needs 15 g and fits both published ratings. These are recipe examples using brew-water volume. Your preferred strength and bean density can change the result.
How we reached this conclusion
TIMEMORE C5 Pro: 25 g catch capacity. 0.4 L × 60 g/L = 24 g. 1Zpresso Q Air: 15–20 g stated capacity. 0.25 L × 60 g/L = 15 g.
A lighter bag trades against a more self-contained handle
The Q Air removes about 275 g, roughly 43% of the C5’s stated grinder weight, from a carried kit. That is meaningful if coffee gear travels daily. The C5 instead folds its handle against the body, while the Q Air handle is a removable piece and its case is optional. The weight comparison excludes cases, beans and accessories and says nothing about the force needed to grind.
How we reached this conclusion
TIMEMORE C5 Pro: Approximately 640 g with a folding handle. 1Zpresso Q Air: 365 g specification with an optional case. (640 - 365) / 640 is approximately 43%.
Neither solves constant setting changes with an external dial
If two people use different brewers every morning, both grinders require access to an internal adjustment. The C5’s larger usable batch and the Q Air’s lower weight do not remove that recipe-change step. Record settings for each method and be prepared to adjust when beans change. If easier setting access is the real reason to upgrade, compare an external-dial model before choosing between these two.
How we reached this conclusion
TIMEMORE C5 Pro: Internal adjustment beneath the burrs. 1Zpresso Q Air: Internal Q-series adjustment beneath the burrs.
Choice A
TIMEMORE, C5 Pro Black
C5 Pro
The standard C5 Pro keeps the folding handle and metal body, with coarser adjustment steps than the ESP version. It suits a measured daily filter brew.
- Best matched use
- Your usual filter brew is around 400 ml at 60 g/L.
Checked facts
- Usable batch limit: 25 g manual load limit and catch cup
- Published weight: Approximately 640 g
- Handle: Folds against the body
- Adjustment location: Internal
Choice B
1Zpresso, 1Z-QAIR01-BK
Q Air
A light, small-dose hand grinder for one filter coffee. The 15-to-20-gram capacity makes it less convenient when a partner wants a cup too.
- Best matched use
- Your priority is a light kit and a small solo dose.
Checked facts
- Usable batch limit: 15–20 g capacity
- Published weight: 365 g specification
- Handle: Removable, non-folding Q Air handle
- Adjustment location: Internal
Meaningful differences
What changes the fit
| What changes | TIMEMORE C5 Pro | 1Zpresso Q Air | Why it matters |
|---|---|---|---|
| Usable batch limit | 25 g manual load limit and catch cup | 15–20 g capacity | Follow the C5 manual’s 25 g loading recommendation rather than its 30 g chamber headline. |
| Published weight | Approximately 640 g | 365 g specification | The Q Air saves about 275 g before accessories. |
| Handle | Folds against the body | Removable, non-folding Q Air handle | Do not apply Q2 S folding-handle instructions to Q Air. |
| Adjustment location | Internal | Internal | Both require access below the burrs when changing grind settings. |
What you give up
Every choice has a cost
If you choose TIMEMORE C5 Pro
- Keep loads within the manual’s 25-gram recommendation. A 30-gram chamber specification does not override it.
If you choose 1Zpresso Q Air
- The adjustment dial is internal, so switching methods is less direct than turning an external ring.
Recommendation switch
