Portable Battery Powered Burr Coffee Grinder with 40 Adjustable Settings & 35g Capacity, 1800mAh Rechargeable Coffee Bean Grinder with Conical Ceramic Burr, for Travel, Camping, Office, Espresso, etc

20 BUCKS This grinder is very slow and should be. It's basically a battery operated hand grinder. I purchased this to use with my Bellman cx25p for camping/fishing. while testing this out I set it to the finest setting and ran 18 gram shot through my espresso machine with a pressurized basket (40 out in 27 seconds). It was a very balanced ,smooth espresso. I topped it off with 180 ml of frothed oat milk and was shocked how good the latte was. the battery lasted for over a 1/2 hour it takes about 12 minutes to produce 50 grams 25 g max in hopper. this is about how long my bellman takes to heat up so not a problem. to be able to grind fresh on the run is so nice. next i am going to see if i can put the motor to a K6 Kingrinder somehow, like they do with a drill. espresso makers and grinders fail often this is a great backup for 20 dollars.

Having to run the eggshells in a blender first.
