HARIO Smart G Electric Handy Coffee Grinder

Meet the HARIO Smart G Electric Handy Coffee Grinder, a sleek and portable mill that blends the best of manual precision with powerful electric convenience. Designed for coffee lovers who value both quality and mobility, this grinder features ceramic burrs, a rechargeable motor, and a compact form factor so you can enjoy freshly ground coffee anywhere—from your kitchen countertop to a campsite or hotel room.

At its heart is a 24 g bean capacity, enough to grind for one to two cups in a single go. The grinder’s ceramic conical burrs deliver consistent grind size and minimal heat transfer, preserving the delicate flavour oils and aroma of your beans. Thanks to HARIO’s stepless adjustment, you can dial in a wide range of grind sizes—from filter to moka pot or French press.

What makes the Smart G truly versatile is its two-way functionality: use it as a conventional hand grinder with the crank handle, or attach the motorised Mobile Mill Stick to grind with just the push of a button. The motor is powerful enough to handle even hard, lightly roasted beans—no more tiring hand cranking when you’re in a rush.

Powered by an internal lithium-ion battery, this grinder is USB rechargeable and delivers approximately 25 grinding cycles (≈ 20 g per grind) on a full charge. This portability means you can grind fresh beans while travelling, camping, or commuting. The grinder’s on/off switch is simple and intuitive, making it ideal for both beginners and seasoned brewers.

HARIO built this grinder with practical materials: ABS resin for the body, stainless steel for the burr shaft, and PMMA for the hopper and holder. The total height is 332 mm, with a width of 59 mm and depth of 53 mm, making it compact enough to pack in a bag or backpack. It weighs in at around 800 g, battery and all, so it’s sturdy yet still portable.

Maintenance is straightforward. The grind chamber can be disassembled for cleaning and the ceramic burrs are durable and easy to rinse. The clear hopper allows you to monitor bean levels, and the adjustment knob gives you fine-tuning control over grind size. Whether you’re dialing in a pour-over recipe or brewing a quick moka pot, the Smart G adapts to your style.

For mobile baristas, travellers, or anyone who enjoys grinding on demand without the bulk of large grinders, the Smart G Electric Handy Grinder is a game-changer. It delivers reliable performance, versatility, and portability in a compact, thoughtfully engineered package.
