Our take on the Portable Electric Coffee Bean Grinder

This is a small cordless burr-style grinder with a clear lower chamber and a dial for stepless fine-to-coarse adjustment. It runs on a 1500 mAh battery charged over USB-C and is rated to grind about 25 g of medium coffee three times a day for a week per charge. The bean and powder bins are dishwasher safe, and a light signals charging status. It suits one or two cups at a time, travel and office use; it holds far less than a countertop grinder and its plastic body and small motor put it below burr grinders for espresso-level consistency.

About the Portable Electric Coffee Bean Grinder

This is a portable electric coffee bean grinder with a cylindrical body. It has a matte upper section with a round power button and a transparent lower chamber, so you can see the grinding as it happens. An adjustable dial marked for fine and coarse settings sets the grind thickness continuously.

The finest setting grinds coffee powder to 30 mesh (more than 90%). The grinder stops automatically when there are no beans left to grind. A blue light shows while it works, and a red light flashes to signal that it needs charging.

It charges through a USB Type-C cable and has a 1500 mAh lithium battery. A 3-hour charge gives about one week of use at 3 grinds a day, with 25 g of medium-thickness coffee beans per grind. The bean bin and powder bin are dishwasher safe.

Questions and answers

How fine can it grind?
The maker claims the finest setting reaches 30 mesh, with over 90% of grounds at that size. That is fine enough for most drip and pour-over brewing, but expect less consistency than a dedicated espresso burr grinder.
How many cups per charge?
The maker rates one charge at about a week of use, grinding 25 g of medium coffee three times a day. A full charge takes about 3 hours over USB-C.
Can I wash the parts?
The bean bin and powder bin are dishwasher safe. The motor housing and battery section should not be immersed.
How much coffee does it hold?
A single load is around 25 g of beans, enough for roughly two to three cups depending on strength. It is not built for grinding a full bag at once.
Does it work while charging?
The description does not say. The light shows charging status, and the maker lists a 3-hour charge time, so plan on charging before use.
What is in the box?
The grinder and a USB-C charging cable. No wall adapter is listed.
