This looks like rubbish. If you care about coffee get yourself a kingrinder knockoff on AliExpress or any solid aluminum model with a stainless steel burr on Amazon.

If you drink light roast coffee then I wouldn't use a grinder with stainless steel burrs. Likewise uncoated stainless burrs can dull after as little as 10-15 kg of coffee. As they dull the particle size deteriorates leading to bitterness from an uneven extraction. Hand grinders with a DLC coated burrs are around $140-$150 last I looked. This ceramic burr grinder at $10 is a decent purchase if you drink light roast coffees that have a "softer" bean.

I used to grind my own beans and this looks like fun for camping and such, but I tried Nespresso at a friend's and it was a game changer. Melozzio and Double Espresso for the win. A little on the expensive side sure, but that first cup of coffee each day is something to look forward to so it ought to get worthwhile attention. I'd be more inclined to buy a power source that could run my Nespresso on a camping trip than go back to grinding. I may have a problem.

Will this work for grinding peppercorns?
I would think yes. Coffee beans are harder.would be interesting to see the resullt.
Edit: it's the other way around. Peppercorns are much harder.

That's when you chew the beans. I don't know how humanity invented something that requires so much effort for so little result.

I do appreciate a fresh ground cup of jo, but when you accept a 2nd cup from your friend and then watch 3 minutes of grinding you start to feel bad.
I was in a situation, and I chewed the roasted beans. Wow did that stain my teeth a deep yellow for the day, and I don't think they've ever been as white since.

Can't speak on this model, but I've been using a Timemore C2 for 5 years now, and since I only make one cup at a time I really have no interest in an electric grinder. Once you get your grind size honed in, you're only spending 10-15 seconds grinding, and you're already waiting for the water to heat up so there is really no downside.

Yeah but ... I have an electric grinder and haven't even unboxed it. I have a hand grinder that I've already used to the point it loosens every time I use it why I'm just looking at this one.

Point is, that for coffee nerds like me and your friend the grinding is kind of ... Zen. And enjoyable in its own right. FWIW...
Serious question, but how long does it take to hand grind enough for a full 12cup pot? I am not that big of a coffee nerd and I like my conical burr grinder but my best guess answer to that question is definitely a blocker for me (and it may not even be relevant for a lot of coffee nerds but I just like the convenience of drip and to get things moving in the morning because I hate the mornings haha)

grinding 23 g of beans (standard 1 serving) on medium for a fresh pour over takes <1 minute. I know because I've timed it and I do it every day.

I'll be honest though, lately I've been creatively lazy and attach my power drill to the top and let it do the cranking. I got this idea from a high end coffee shop that I saw do the same.
Brilliant; I do similar but witha hand beater attachment to stir my peanut butter. I felt compelled to share in case you don't already do it too because damn does it work well

Previous reply got mangled and then the content lost.

Anyway, I too have a cheapo we've been using for a while, and expressly for when we want something different, or Mrs. Gryhnd wants her own type etc. Downside is the manual burr grinders are all slow in my experience. So if you have tennis elbow, consider the irritation, lol

Hand grinder is really just for a 23g (of beans) single serve... maybe double serving... it's not for 12 cups haha.
