The best portable electric coffee grinder for you depends on how fine you grind, how many cups you need between charges and how much room it gets in your bag. This guide covers six cordless burr grinders that charge over USB-C. The listings differ in grind settings, battery size, weight, bean capacity and how the parts come apart for cleaning.
Every detail here comes from each product’s Amazon listing, and we did not test these grinders in person. Scores follow the four criteria in the How We Score section, and our Editorial Policy explains how we handle listing data.

How to Choose the Best Portable Electric Coffee Grinder for Travel and Home
Pick a burr, not a blade
All six picks use burrs rather than blades, which grind to a set size. Burr size is listed on only two picks.
Check cups per charge, not just mAh
Battery size gives a rough idea, but a listed cups-per-charge figure tells you how often you will plug in.
Match the settings to your brewer
More steps help when you dial in espresso. If you mostly brew pour-over or French press, 30 to 40 settings can be enough.
Weigh the bag space
These picks run from 6.57 to 8.6 inches tall. Check the listed weight and whether a pouch or bag comes in the box.
Look at batch size
Single-dose grinders may hold 15 g, enough for one cup, while others list 30 g or more for two cups or a larger brewer.
