gpwpat said:I don't understand the manual grinder. I have a small electric grinder. it is the size of a standard glass. Pretty much the same size as the manual grinder. most of us travel with some sort of power inverter. I just plug in my small electric grinder and get fresh coffee. Let the battery do the work.
Is the small electric grinder a conical grinder or a burr grinder? I'm not a fan of the conical grinder since you can overheat the beans as well as the inconsistent grind. I bought a small conical grinder a long time ago and now use it strictly as a spice grinder.
Also, I don't bring an inverter along. I don't bring anything along that needs 120V AC.
