A 0.1-gram scale to two kilograms with four modes including flow rate, and thirteen hours of use per charge.
Where we land on it Thirteen hours of continuous use or ninety days of daily brewing on one charge, in a 4.1-inch square that fits under most machines. The only battery figure on this shelf, and a flow-rate mode to go with it.
Eight listings. Three say AAA. Two give a cell capacity in milliamp-hours, which tells you nothing without a draw figure. One gives hours and days.
For a rechargeable scale that lives under a machine, that is the number that decides whether it is charged when you want it.
Weight, time, ratio and flow rate. Nothing else on this shelf puts all four on the display — one scale shows flow, one mentions ratio in its text, and the rest show weight and a clock.

That is the maker’s figure for daily use, alongside 13 hours of continuous running. No other scale on this shelf publishes any battery figure at all — three run on AAA cells and two more give a capacity in mAh without a duration.
It shows the powder-to-liquid ratio as you brew, which is the number behind every pour-over recipe. One other scale here mentions the 1:15 to 1:18 rule in words; this is the only one that puts the ratio on the display.
For a portafilter and a cup, no — that is what it is sized for. For a V60 with a server, yes: the Hario on this shelf is 120 by 190 mm (7.48 in) for exactly that reason.
These coffee machines share the category and the price bracket. Only what each one states is shown; an incomplete column would mislead.

A small espresso bench where the scale lives on the drip tray and gets charged once a season
Amazon reports what buyers took in the month before this page was last checked: at least 500.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for coffee equipment and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
2 kg (4.4 lb) × 0.1 g (0.004 oz) · 6 modes · water resistant
The one scale here built to survive a drip tray. Six modes, auto-start timers and a silicone cover — which addresses the thing that actually kills coffee scales.
Best for: Espresso on a wet drip tray, which is where scales go to die.
2 kg (4.4 lb) × 0.1 g (0.004 oz) · built-in timer · V60 footprint
Built around the V60 rather than adapted to it: the footprint fits a dripper and a carafe, and the timer sits right where you are looking.
Best for: Pour-over and immersion brewing, where a timer matters more than refresh speed.
0.1 g (0.004 oz), 750 g (26.5 oz), 5.7 × 3 × 0.7 in, lid that becomes a tray, 6 units, no timer
A slim 0.1-gram espresso scale to 750 grams, whose lid flips over into a grounds tray.
Best for: Dosing beans and shots beside an espresso machine, where the timer is on the machine already
