Looking for a coffee grinder that balances portability and performance?
The Starseeker 2-in-1 Coffee Grinder features a dual-mode design with both manual and electric grinding, allowing you to switch freely between the slow, ritual feel of hand grinding and the speed and convenience of powered grinding. Its 10-core stainless steel conical burrs deliver uniform particle size with minimal fines, helping to lock in the full flavor of your coffee. The external micro-adjustment dial lets you quickly switch between grind sizes for espresso, pour-over, siphon, and French press, offering intuitive control and a professional feel for both home and outdoor brewing.
The Starseeker “Explorer S 2-in-1 External-Adjustment Manual & Electric Coffee Grinder” is a portable grinder that combines both manual and electric grinding modes, designed to meet a wide range of brewing needs including home and outdoor pour-over, espresso, siphon, and French press.


ual-mode switching design
Manual mode: Remove the electric module, attach the handle, and grind at your own pace with smooth, low-effort hand grinding.
The magnetic handle connection design eliminates the need to align threads, making attachment and removal smooth and secure.


How do you switch between manual and electric modes?
Electric mode: Turn off the Starseeker Electric Coffee Grinder and remove the hopper, then gently pull out the electric module and insert the magnetic handle into the slot. To switch back to electric mode, remove the handle, align the electric module with the slot, insert it, and once you hear the “click” of the magnetic connection, you are ready to grind.


How long does the Starseeker battery last, and how long does charging take?
The built-in lithium battery in the Starseeker 2-in-1 Grinder takes about 2 hours to fully charge. In electric mode, it can run continuously for around 60 minutes (equivalent to grinding for roughly 15–20 cups of coffee), which is more than enough for over a week of everyday use.


Grinding core and burr adjustment structure
Equipped with 10-core stainless steel conical burrs,
the finely finished cutting surface produces uniform particles with low fines, preserving flavor to a high degree.
Grind adjustment: An external micro-step adjustment dial on the body allows precise grind size control according to your brew method (espresso, pour-over, siphon, French press, etc.), with intuitive and easy operation.


Note: Allowing the lithium battery to fully discharge may result in failure to recharge.
(12-month warranty in Hong Kong; burrs are not covered under warranty.)
