Cordless Electric Grinder SS Burrs - Silver

This small, electric coffee grinder features a conical stainless steel burr set, an external adjustment ring, and a USB-C rechargeable battery. It works really well for most roast levels but can jam up (and break) on under-roasted coffee. The 25 g capacity is perferct for pour over drippers, Clever brewers, and Aeropresses, and the compact size is great for tight spaces or for putting away in a drawer after your daily brew. Also available in Graphite.

It might seem odd to talk about an electric-powered "hand grinder" for coffee, but here it is! This USB-C rechargeable mill comes from the same factory that makes our all-metal hand mill, and features the same stainless steel conical burr set.

It can do a wide range of grinds, from espresso fine to Chemex coarse, but the sweet spot is in the pour over range where there is a significant amount of adjustability. Grind adjustments are handled via an external adjustment ring with 38 steps that makes adjusting the grind much easier, more straightforward, and more repeatable. That being said, the grinder might not get coarse enough for people who like a really coarse French press grind, and even though it can grind fine enough for espresso it really lacks adjustability in that range. Using our Lelit MaraX, water barely passed through the puck using a "1" grind and a "4" resulted in a pretty watery espresso pouring out of the portafilter with gusto. So it grinds very fine, but we might not call it an espresso grinder.

The slow burr rotation speed is really akin to a hand grinder, except you don’t have to labor over actually grinding the coffee nor wait around for it to finish. The mill turns itself off when the grinding is done, and grinding 25 grams takes about 30-45 seconds depending on the coffee and how fine the grind is. Very fine grinds will take a little longer, of course. The body has plastic components while the burrs and drive shaft are stainless steel. It’s worth noting that static causes some grinds to cling to the burrs after grinding, but we've found a few gentle taps to the body of the grinder can knock the grinds loose without too much trouble. The grinds catcher presses on to the bottom of the grinder with a friction fit, so don't tap that part too hard or the grinds might go flying!

The power button on top has a LED on top which illuminates steady blue while it's grinding, and switches to flashing blue when the grinder completes the job and turns itself off. The LED changes to a red color when the battery is low and while it's recharging. You'll know its fully charged when the LED turns to blue... and then turns off. Blink and you'll miss it! The battery can last a good amount of time; we have gone 2+ weeks of daily use between charges. 

The grinder itself is pretty compact, some might even call it portable! The fact that it can go back in the drawer with other coffee stuff, keeping precious counter space clear, is an added bonus. It’s relatively quiet compared to electric mills, certainly way more serene than an old Krups that wakes up the whole house. For us, it fits the bill and takes some of the work out of our morning brewing routine. If you don’t need large amounts of coffee, and want something that can be put away after use, we think this is a great option! We also have this mill available in a nice blue gray, or what we're calling 'Graphite'!

Recharging:

  • Use the included USB-C cable to charge the grinder.
  • Standard power charging bricks (5w - 20w) are recommended.
  • When you plug in the grinder, the LED on the power button should turn red. That indicates it is charging.
  • When the grinder is done charging, the LED will briefly blink blue and then turn off.
  • Do not use high wattage or super-speed charging bricks as these can cause charging issues.

Cleaning the Burrs:

  • You can easily clean the burrs from the bottom with a dry brush.
  • Turn the grind setting full course and use the included brush to sweep out old grinds.
  • We do not recommend removing the lower burr for deep cleaning, though you may do so at your own risk.
  • Damage or malfunction caused by removing the lower burr is not covered by any warranty.

Cleaning the Grinder:

  • Do not submerge any part of the grinder in water, and certainly don't put any part of the grinder in your dishwasher.
  • Wipe the exterior of the grinder with a dry towel or brush as need.
  • A damp towel can be used to wipe the sides of the grinder, but be mindful to keep water away from the power button and USB-C port.

Filling the Hopper:

  • Do not overfill the hopper.
  • Take care to line up the "Lock" and "Unlock" symbols with the triangle indicator.
  • Forcing the motor section onto the burr shaft when its not aligned or when the hopper is too full is not good for the mill and can make it stop functioning.

Grinding:

  • Do not grind anything besides roasted coffee.
  • Grinding un/under-roasted coffee or other materials can damage the grinder and is considered user error.
  • Always make grind adjustments with an empty grinder.
  • Avoid adjusting the grinder when the hopper is full or while grinding as this can put unnecessary stress on the adjustment mechanism.
