The 8311 portable coffee grinder combines a ceramic burr grinder, coffee mug, and reusable filter into one compact, travel-ready unit. With 7 precise grind levels—from extra coarse for French press to very fine for espresso—you can tailor every brew to your preference.
The low-heat ceramic burr preserves your beans' natural oils and aroma, while the rechargeable battery delivers 25+ cups per full charge via Type-C USB. Simply add beans, double-click to start grinding, pour hot water slowly, and enjoy fresh coffee anywhere.
Its lightweight, cordless design fits easily in backpacks or suitcases, making it perfect for camping, hotels, offices, or RVs. The 300ml cup capacity and BPA-free, food-approved materials ensure safe, convenient use. One-button operation and easy cleaning make this 3-in-1 system your ultimate travel coffee companion.
