About This Product
A 2kg / 0.1g rechargeable scale with built-in timing, sized for an espresso puck or a pour-over decanter. The headline specs are 2kg / 0.1g resolution, USB-C charging, and an automatic timer that triggers when the scale detects pour. Reviewers confirm the basic execution — two of 19 cite solid build, two cite a compact footprint that fits beside an espresso machine without crowding the counter, and one notes weight accuracy reads true. At this sample size we'd call those signals encouraging, with thin per-claim evidence behind each.
This is a tool for pour-over and daily countertop espresso routines where 0.1g resolution suffices; the automatic timing favors hands-free flow tracking on single-cup brews. Two reviewers cite long battery life with USB-C charging, suggesting it tolerates daily-use rhythms without needing frequent top-ups.
In day-to-day use, the auto-timer is meant to start when it senses the pour, leaving your hands free to manage the kettle or portafilter. The USB-C port and multi-month standby mean charging is an occasional task rather than a routine one, and the slim footprint sits beside an espresso machine without crowding the station.
The caveats cluster around espresso. Three of 19 reviewers report consistency problems on that workflow specifically — an erratic timer, unreliable pull-timing, and one charging battery that wouldn't hold. A separate reviewer flags that the marketing copy's 0.01g precision claim actually reads 0.1g on the unit itself, which matches the spec we'd expect from a scale at this size and price.
Reach for it if pour-over and casual home espresso are your main use cases and 0.1g resolution is enough; look elsewhere if you need a scale that has to time every espresso pull dead-reliably.
Is UNIWEIGH Mini Rechargeable Espresso Scale with Timer Right for You?
Does the auto-timer work reliably for espresso pulls?
Mixed signals at this review count. Three of 19 reviewers flag espresso-side reliability problems — an erratic timer, unreliable pull-timing, and one charging battery that wouldn't hold — clustered around the espresso workflow rather than pour-over. If consistent shot-timing on every pull is non-negotiable for you, this is the documented weak spot.
Is it actually 0.01g precision like the title suggests?
No — one of 19 reviewers explicitly flags that the marketing copy's 0.01g precision actually reads 0.1g on the unit itself. The headline spec is 2kg capacity at 0.1g resolution, which is adequate for pour-over and home espresso but not the finer precision the listing wording implies.
How long does the battery last between charges?
Two of 19 reviewers cite long runtime, and one specifically contrasts the USB-C charging with disposable-battery scales as a reason it tolerates daily use. That's encouraging at this sample size, though a separate reviewer reports a charging battery that wouldn't hold — so the battery story isn't uniformly positive.
Will this fit next to my espresso machine without crowding the counter?
Two of 19 reviewers describe the unit as small or compact enough to share counter space beside an espresso machine. The synthesis frames it as sized for an espresso puck or a pour-over decanter, so the compact footprint appears to be one of the more reliable selling points at this review count.
Is the build quality solid?
Two of 19 reviewers cite quality or good build, and one notes the weight accuracy reads true. Those are encouraging signals at limited sample size with thin per-claim evidence — call it adequately built for daily countertop work rather than uniformly proven.
Is this a good scale for pour-over coffee?
This is the use case the synthesis points to most clearly — pour-over routines where 0.1g resolution is enough and the automatic timing favors hands-free flow tracking on single-cup brews. The espresso reliability caveats reported by some reviewers don't appear to extend to pour-over use.

Can I use this for a high-volume espresso bar?
No — the synthesis explicitly flags high-volume espresso workflows that demand consistent timing on every pull as the not-good-for case. With three of 19 reviewers reporting erratic timer or unreliable pull-timing behavior, busy back-to-back shot pulling is where this unit appears to struggle most.
Does it charge over USB-C?
Yes — USB-C charging is one of the headline specs, and one reviewer specifically contrasts it favorably with scales that burn through disposable batteries. That matters if you're rotating it through daily-use rhythms without wanting to hunt for spare cells.
What's the maximum weight it can handle?
2kg capacity at 0.1g resolution, per the listing and the synthesis quality paragraph. That ceiling is comfortable for an espresso puck plus portafilter or a pour-over decanter, but it's not built for weighing a full kettle of water before pour.
How does the automatic timing actually start?
The synthesis describes the auto-timer as triggering when the scale detects a pour, which favors hands-free flow tracking on single-cup brews. Some reviewers report the trigger behaving erratically during espresso pulls specifically, so the hands-free claim appears to hold up better on pour-over than under espresso flow rates.
Can I also use this scale for weighing tea or general kitchen tasks?
The 2kg / 0.1g range and portable form factor make it functionally usable for weighing loose tea or small kitchen quantities, though the listing positions it specifically around espresso and pour-over coffee with the auto-timer geared to pour detection. No reviewer feedback in this sample addresses tea-weighing use directly.
Category: What features matter most when buying a tea scale?
Tare is non-negotiable so you can zero out a cha he or gaiwan. Look for a platform sized to your teaware (small jewelry footprints suit a tea tray better than wide coffee scales), a configurable or generous auto-shutoff so the scale does not die mid-session, and a large readable display. A built-in count-up timer is a strong nice-to-have because it consolidates two devices into one and shows weight and elapsed time simultaneously.

Category: What scale do I need for matcha?
Matcha is the one tea where 0.01 g jewelry-grade resolution earns its keep. Usucha uses about 2 g of matcha to 70-80 mL of water and koicha uses 3-4 g to 30-40 mL, so a 0.1 g scale leaves a 5% error on the dose that you can taste in the foam structure and thickness. A scale that simultaneously shows grams and elapsed whisking time makes the workflow easier.
Category: Why does my scale read a different weight each session?
The likely culprits are thermal drift (a cold scale brought near a kettle reads high or low until it equilibrates — let it warm up for five minutes), vibration from a nearby appliance, an uneven surface that corner-loads the strain gauge, or a battery dropping below about 30%. Tare accumulation can also compound rounding error over many add-tare cycles, so re-zero from empty between sessions. Chronic drift that persists after re-tare points to a failing load cell.
