1. Best Vibrating Grinder: Tectonic9 Manual Herb Grinder with Electric Dispenser
Pros:- Electric vibrating motor makes sure ground herb doesn't get stuck in grinder
- Combines the best of manual and electric grinders
- Anodized aluminum body is super durable
- Perfect fluffy grind (I tried it)
Cons:- Not technically an electric grinder (but has an electric dispenser)
- Still need to manually turn it
- Sometimes you need to bang it against the table to get the dispenser working again (but it always starts working again!)
The Tectonic9 Manual/Electric Herb Grinder combines the best of manual and electric grinders.
It’s not a fully electric grinder, but its motor sure helps you get the job done.
You still have to manually twist the grinder, like with traditional weed grinders. But unlike traditional grinders (where you have to manually scoop out your herb), this machine actually vibrates the herb out through a funneled dispenser. You can place the opening right above your bowl (or vaporizer chamber), and the machine will dispense a perfect waterfall of ground herb directly where you want it.
Full disclosure: I received a free unit to test out. It works perfectly! While many grinders can get gummed up with the resinous byproducts of grinding, the electric vibrations simply dispel all the ground herb at the touch of a button. It’s awesome!

2. Best Herb-Viewing Window: LONZEN Rechargeable Electric Dry Herb Grinder
Pros:- Can grind up to 2 grams at once
- For added safety, it will not operate while stainless steel blades are exposed
- Features window to show you herb being ground
- Includes two-year warranty
Cons:- Window is made of glass, so it can break if you drop it
- More expensive than some grinders
- Does not fit as much herb at once as some grinders
The LONZEN Rechargeable Electric Dry Herb Grinder stands out because, unlike the other electric handheld marijuana grinders on this list, it features a glass window so you can see your herb while it’s getting ground up.
It boasts a long battery life, so it can be used around 300 to 500 times between charges. This automatic weed grinder also comes in a wide variety of colors. This would make a great gift for the person with hand or wrist issues who also loves nifty gadgets.
It features sharp blades, but it won’t operate while they’re exposed, as an added safety measure.

3. Electric “Tobacco Shredder”
Pros:- Customers say its perfect for cannabis
- Grinds a large amount quickly
- Easy to pulse (and view through lid) to quickly reach desired grind consistency
Cons:- No kief catcher (but customers found great solution -- see review for details)
- It's possible to over-grind into powder (so be careful, and don't grind for too long)
- Does not work for actual tobacco! (Just cannabis!)
This Electric Tobacco Shredder actually works perfectly for cannabis, according to dozens of reviews. And one of my friends swears by this machine!
Fun fact: The only negative reviews of this product are written by people who wanted to shred actual *tobacco* in it.
Customers love how well (and how quickly) it shreds their herb. Some comment that it’s the perfect consistency for a vaporizer. Some don’t know how they lived without it before.
Unlike some herb grinders, this does not have a kief catcher. However, multiple customers mentioned that they used a small paintbrush to remove the kief after grinding.
Be careful not to over-grind your herb. If you press the button for too long, you may end up with a fine powder! However, you can see through the clear lid, so you’ll know just to pulse carefully until you see that your herb has reached the perfect consistency.

4. OTTO Electric Herb Grinder and Roller
Pros:- Grinds directly into paper cone joint
- "Smart" device calibrates milling needs
- Comes with a charger
- Great for marijuana patients with hand or mobility issues
- Just one button to press
- Can be used as electric herb grinder for other smoking devices
- Comes with dozens of paper cones that fit perfectly
Cons:- May need to refill grinder to get enough material fill joint
- May need to bang against table while in use to ensure joint gets filled
- Expensive
- May stop working after a while
This OTTO Electric Grinder and Roller is the best electric grinder and roller available today.
The Otto Herb Grinder uses “artificial intelligence” to calibrate the perfect milling pressure for your cannabis, which is ground directly into a cone. (It comes with unbleached, organic paper cones, which fit perfectly into the transparent lower chamber.)
You do need to tap the affixed plastic chamber down against the table while your robot grinder hums and whirrs. If you don’t tap it during the grinding process, the ground herb may not descend into the paper cone, and may get stuck in the grinder. But since the plastic is transparent, you’ll be able to tell if this is happening.
Full Disclosure: I received a free one to test out. It fills the included cones perfectly. You twist off the end and it’s all set and ready to burn. The package includes one cylindrical plastic “doob tube,” so you can send a friend off with a perfectly-rolled joint, too.
This is perfect for anyone who struggles to roll joints due to hand tremors, injuries, or other motor function challenges. It’s also great for anyone who has cannabis allergies, and doesn’t want to touch their marijuana more than necessary. (Cannabis allergies are actually more common than you might think — they generally pop up after years of exposure to the plant.)
But the OTTO Electric Grinder and Roller reduces the need to actually touch your herb. When the joint is filled, you simply push up on the plastic sides, and it comes out of the chamber. You twist the end and you’re ready to go.
Side bonus: The opening at the bottom of the grinder also fits perfectly over the mesh chamber of a Volcano vaporizer. They’re exactly the same size. (You can use the electric grinder portion of this unit, without attaching it to the plastic lower chamber that normally holds your cone upright.) So if you use other smoking methods, aside from joints, you can still grind cannabis directly into your other hardware.
With this humming robot sidekick, you may feel like a savvy stoner from the future.

5. Wakit Grinders Best Electric Grinder
Pros:- Good customer service
- No manual turning needs
- Battery life lasts a very long time
- Charges with USB
- Ball and chain mechanism grinds to perfect texture
- Durable
- Can see herb being ground
Cons:- Could use an extra tray on the bottom

- Not made in US
The Wakit Grinders Best Electric Grinder stands out because an LED light allows you to actually see your herb being ground up inside.
This way, you get to choose how fine of a grind you want. For example, if you’re using a vaporizer, you might want your cannabis extra finely ground. So with the Wakit grinder, you could press on the button for longer, and watch your herb get ground up into the exact fluffy texture you want.
It’s also convenient that it comes with a USB charger, and the battery life lasts a really long time.

6. Mamba Battery-Powered Herb Grinder
Pros:- Designed for one-handed operation
- Battery powered
- Grinds up to half gram at once
- Funnel attachment for easy packing into nearly any smoking/vaping device
- Affordable
Cons:- Batteries sold separately
- Difficult to clean
- Teeth could break off after sustained, repeated use
This Mamba grinder stands out because it’s super easy to use. You simply place the funnel-shaped tip over your bowl, and ground herb falls directly into your bowl. You don’t even need to touch your weed.
I actually bought this as a gift for someone. It was a huge hit.
The Mamba is designed for one-handed use. People with mobility issues or conditions like muscular dystrophy might appreciate that.
The teeth switch directions, so you won’t get it clogged up. You can grind up to a half gram at once — plenty for one perfectly-ground bowl pack.

7. Best Electric Coffee Grinder for Weed: Cuisinart Supreme Grind Automatic Burr Mill
Pros:- Great for grinding large quantities of cannabis
- Has 18 different grind options
- Removable grind chamber for easy cleaning
Cons:- More expensive than some grinders
- Too bulky for when you only need a small amount of ground herb
- Takes up counter space
The Cuisinart Supreme Grind Automatic Burr Mill is perfect for anyone who has a large quantity of cannabis to grind at once.
Longtime high-consumption stoners know: A coffee grinder will get the job done, fast.
If you need to grind more than an eighth or so at a time, using a normal grinder — even an electric one — could take too long.
Plus, with this grinder, you can choose between 18 different grinds. That means you can specialize the grind for the type of weed you have — or even the type of consumption you have in mind.
For example, if you’re making edibles, a rough grind is totally fine, because you’ll strain the plant material out of your oil or butter anyway. But if you’re going to vaporize this herb, you’d want a much finer grind.
With 18 different grinds, this machine can accomodate all your marijuana uses!

8. Best For the Multitasking Foodie: Cuisinart SG-10 Electric Spice and Nut Grinder
Pros:- Respected kitchenware barnd
- Includes storage pocket
- Dishwasher-safe bowl and lid
- Easy-to-use
Cons:- Only has three speeds of blade
- Bottom container doesn’t detach from unit
- Takes up counter space; not portable
This Cuisinart Herb and Spice Grinder isn’t for your average stoner. It’s for the enlightened cannabis consumer who understands that the right stainless steel appliance can really tie the kitchen together.
Cuisinart makes everything from pots and pans to toaster ovens. They also make an electric weed grinder. Makes sense. You might heat up a snack after using it.

9. Best Industrial Electric Grinder: Waring Commercial WSG30 Electric Spice Grinder
Pros:- Stainless steel blades grind herb in seconds
- Super heavy-duty
- Comes with three jars for storage
- Easy to clean
- Includes pulse function
Cons:- Cannot be overfilled
- Plant material must be dry
- Expensive
The Waring Grinder stands out because it’s gigantic. And powerful.
Are you rolling hundreds of joints? We don’t need to know why. (Are you handing them out at a protest? Or just throwing an awesome party?)
No explanations necessary. (You’re making a music video!) But if you for any reason need to grind weed on an industrial scale, you’ll want a commercial grinder. This one has a brushed stainless steel exterior, so you’ll look pretty pro while pulsing ounces of cannabis into a perfectly ground heap.
(If you do have this much cannabis lying around, you might also want to check out our guide to the best herbal infusers for cannabis. Turn that herb into canna-butter with another awesome kitchen appliance!)
A word of warning: This grinder only works with perfectly dry cannabis. If your herb hasn’t been fully dried and cured properly, it will gunk this up.
But with his machine, if you decide to switch gears, you can also grind cinnamon sticks in seconds (according to reviews). And you might want some cinnamon toast, after smoking all 23 joints you just rolled.

10. Best Electric Grinder with USB Charging: FREETOPHOME Electric Herb Grinder Pen
Pros:- Charges with USB, which makes it super easy to charge
- Very strong motor
- Automatically grinds for 40 seconds when you press button
Cons:- Motor doesn't have variable speeds (just one speed, which is very powerful)
- If your herb is super dry, you may end up with a finer grind than you intended (just stop the motor early!)
- No kief catcher
The FREETOPHOME Electric Herb Grinder Pen stands out because it’s so easy to charge. You can charge it with a USB charger, which you probably already have lying around.
A smart LED light alerts you when it’s charging, and lets you know when it’s fully charged. The battery charge can last for several weeks, even with frequent use.
People with arthritis love with this device. It fits a little more herb than some other electric herb grinder pens, and thanks to the clear plastic, you can watch your herb being shredded.
It has a powerful motor, and an automatic grind time of 40 seconds. This may result in a very fine grind. In fact, if you’re using super dry herb, you may end up with more of a powdery consistency. But you can stop the grind early — after just a few seconds — for a perfect grind.

11. Best For Grinding Weed in Your Coffee Grinder: Chefman Coffee Grinder
Pros:- Cup detaches for easy clean up
- Incredibly strong motor
- Fantastic customer service
- Can grind up to 2.5 ounces
- Dishwasher safe
Cons:- Electrical cord is shorter than some users expect
- Not portable
- If you use it for coffee as well, your herb may taste like coffee
The Chefman Coffee Grinder is perfect for grinding large quantities of cannabis.
Cannabis consumers are resourceful. Sometimes, a coffee grinder will work in a pinch. This is great for grinding large quantities. Just don’t forget to clean it before your next coffee grind.
Can you buy an electric weed grinder with kief catcher features?
Yes! But most of these models are poorly reviewed. Customers say they don't work well, and just end up creating more work for the user. But if you noticed the Easy Grinder Electric Weed Grinder Pen reviewed above, you'll see that it stores kief underneath the blades. Customers say they can obtain the kief from beneath the blades (carefully!) after using the device.
What is an electric weed grinder pen?
Electric weed grinder pens are awesome. They're sleek and cylindrical, and about the size of a pen. (Hence the name.) But don't let the name confuse you: there's no relation to vape pens.
The only drawback to electric weed grinder pens is their size. If you need to grind a lot of herb at once, they may not be right for you. They can only grind about a half gram or so effectively at once.
But if you're filling a vaporizer chamber, or a bowl, or even a pre-rolled cone, they're amazing. Because the grinder has a nozzle, you can simply position it above the item you want to fill, and press the button. This is about as easy as packing a bowl will ever be.
This makes electric weed grinder pens particularly convenient for anyone with cannabis allergies, who wants to avoid touching herb with their fingers any more than absolutely necessary.
What's the point of an electric weed grinder and roller?
You may have noticed the Otto Electric Grinder and Joint Roller reviewed above. This model grinds your herb and automatically fills a pre-rolled cone, creating a perfect joint. You don't even have to touch the herb.
And that's precisely the point: Convenience. Make joint-rolling easier on yourself (or a loved one -- particularly one with hand or wrist issues).
Of course, if smoking is really getting too difficult, you could consider eating edibles instead. In that case, you won't need a grinder at all. Just check out our guide to making your own cannabutter for detailed instructions!
