How to choose

Grind settings and burr types

Grind settings set how fine or coarse the grounds come out, and a burr mill crushes beans between two burrs for a uniform grind. The OutIn has 28 settings, the LEBURRY and the LAMIDO have 38 settings each, the AAOBOSI has 60 settings and the TIMEMORE has 30 settings. Compare the setting count with the brew methods you use each day.

Battery and charging

Battery size and recharge time decide how much use you get before you plug the grinder in. The OutIn recharges in 1 hour and gives up to 18 shots of espresso on a single charge, the AAOBOSI recharges in 3 hours and powers up to 35 cups, and the TIMEMORE reaches a full charge in 3 hours. The LAMIDO and the AAOBOSI grind while charging, so a low battery does not stop a brew. Compare recharge time with how much you grind away from an outlet.

Capacity and upkeep

Capacity is how much coffee the grinder holds per batch, and upkeep is how you clean it after grinding. The OutIn holds 25 g, the LAMIDO holds 25 g in its hopper with a 50g container, the AAOBOSI holds 80 g, the LEBURRY holds 110 ml and the TIMEMORE holds 50 g. Compare capacity with the amount you grind each day.
