Best Electric Grinders 2020

If you spend a lot of time smoking weed, you’ve probably spent a lot of time grinding up your herbs and cleaning your grinder to prevent sticky build-up. If you smoke because of a condition like arthritis, carpal tunnel, or another type of chronic pain that limits your dexterity, this can be a challenging and even debilitating process. Fortunately, the old-fashioned manual hand grinder is not the only option on the market for regular smokers. An electric weed grinder does all the dirty work for you, allowing for a virtually hands and labor-free experience.

What’s An Electric Weed Grinder?

Electric grinders are exactly what you’re picturing – an electric version of your classic weed grinder that does the work of your wrists for you. In some cases, electric weed grinders will even dispense your weed to fill a joint or bowl for you. As with most weed accessories, they can range anywhere from simple and affordable to luxurious and expensive. We’ve rounded up our favorite electric weed grinders so you can decide what piece is best for your needs and budget.

4 Best Herb Electric Grinders

Chewy 2.0 Electric Grinder



$ 49
  • 3 Grams Capacity

The Chewy Grinder is a unique contender in the electric grinder market, primarily for its design. While loading your herb, you’ll notice why it’s different. Opening the grinding compartment is like opening a stapler; when lifting up the top cover, it simultaneously pulls back a spring-loaded push block which is used to push the herb into the grinding teeth, imitating the pressure and motion of hand grinding. The Chewy also grinds differently: it slices the herb instead of crushing it, so you’ll end up with a fluffier product in your bowl and less of it stuck to your grinder.

The Chewy runs on a 9v battery, so there is never anything to recharge, and it gives off more power than other electric grinders. It’ll probably take about 3000 grinds before you’ll have to replace the 9-volt battery.

The design is sleek, and the one-handed operation requires minimal hand strength for those with arthritis. Boasting a capacity of 3 grams, and grind on-demand ability, The Chewy is a great portable electric grinder. The parts are removable and non-stick for ease of cleaning. The Chewy is not odor-proof and requires a separate bag to accomplish that goal.

Banana Bros OTTO Automatic Grinder

$ 128

The Banana Bros OTTO electric grinder is a bit more pricey than some of the other competitors, being in the $100+ range. It’s primarily advertised as an automatic rolling machine, however, does less rolling and more packing cone blunts. Although packing cones is its primary purpose, it can be used for filling other contraptions as well.

The design is simple and intuitive with the unit hinged at the grinding chamber with a tab latch, instead of being magnetic or screw-on. Depending on the difficulty of use with the tab latch, it should be easier on arthritic hands than a screw-on.

The grinding chamber is designed similar to a traditional herb grinder with big chunky teeth. One of the jaws is spring-loaded to imitate a traditional manual grinder by adding pressure to the teeth to enhance the grinding action.

Once loaded, the unit is actuated with the press of a button. The battery life claim is that it can fill 20-30 cones before needing to be recharged, which you can do with the included micro USB cable.

The cone loading tube is magnetic and odor-proof, so you can load those cones to perfection without raising any suspicions. Also included is a magnetic O-funnel to fill other devices as well.

What’s In The Box:

  • OTTO grinder
  • Measuring Cup
  • USB Rapid Charging
  • Cable
  • O-Funnel
  • 4-In-1 Tool
  • Fresh Seal Cone Tube
  • 20x Premium Cones

Quant Premium Electric Grinder


$ 79
  • Available In 2 Colors

The Quant Electric Grinder is a pen-style electric grinder made of stainless steel. Because of that material, it’s bound to be a bit heavier than some of the other portable grinders out there. The grinding blade is also made of stainless steel and shreds your herb at 24,000 RPM. Grinding is done with the touch of a button (for around 10 seconds) and dispensed with one hand, which is useful when packing a bowl, vape, or blunt.

The design is straight-forward but not modular as the battery, motor, and blade are all part of the same piece. The grinding chamber is screwed on and off, which could become a problem with the build-up of kief. The end of the grinding chamber has a nozzle for directing the herb where you want it, and has a magnetic cap for when you want to store it. Besides, the storage capacity of the Quant Electric Grinder is ample.

At around 6+ inches in length and about 1 inch in diameter, its less of a pen and more of a magnum marker.

What’s in the box:

  • Quant Electric Grinder
  • USB cable
  • User manual
  • Size & Weight: 27(D) * 160(L) mm
  • Grinder 198g
Pen Simple electric grinder


$ 69
  • Up To 1.2 Grams Of Storage

The Pen Simple is less of an electric grinder and more of an electric dispenser. You have to manually grind the herb (which isn’t great if you have mobility issues in your hands) and you can store up to 1.2 grams (or 3 grams without the grinder). So you can grind what you need ahead of time and store almost an eighter to take with you on your adventures. The Pen Simple allows for one-hand dispensing with the push of a button, which is rather handy when filling a bowl, pipe, doob, or vape. This means more herb where you want it, and less on the ground or in your lap.

Pen Simple’s modular design allows for you to adjust the device to suit nearly any type of need. You can utilize the Pen Simple in three ways: direct grind, grind/store/dispense, or store/dispense. Each piece is made of anodized aluminum that screws together to make a whole unit totaling about 7 inches (~175mm) in length and 1-inch diameter (~25mm), so less of a pen and more of magnum marker. The unit is water resistant and non-odor-permeable when the point plug is inserted, so you can enjoy your outdoor activities without worrying about ruining your herb or your experience. With a claim that you can dispense into 75 devices, and with the included micro USB charging cable, you don’t have to worry about replacing the battery.

There have been some minor complaints that the grinder doesn’t get as fine a grind as some might want, however overall it seems everyone that has this product is pleasantly surprised with its usability.

What’s in the box:

  • Pen Simple modular grinder/dispenser
  • Loading funnel
  • Micro USB charging cable
  • Point plug

Are there electric herb grinders with kief catcher?

Since electric grinders are still a relatively new introduction to the market, we have yet to find an electric herb grinder that has an efficient kief catcher. Surely with more time, testing and researchers, some of these companies will offer a kief catching option so you can save the kief and strengthen your doses.

How to use an electric weed grinder?

Electric weed grinders are designed to make your whole joint rolling (and bowl packing) experience as easy as possible. Gone are the days of wasting all of the goodness a flower has to offer — weed grinders make more surface area available, meaning more THC can be consumed from every flower.

There are both corded and rechargeable battery powered electric grinders but the process for use is the same.

How to clean an electric weed grinder?

Cleaning your electric grinder is a necessary part of the cannabis experience. All of that beautiful, THC-filled resin is also sticky and can interfere with the operation of your device so it’s best to keep it clean. The best way to do so is a somewhat controversial topic in cannabis culture and it also depends on the material your electric grinder is made out of.

If it’s metal, keep in mind water will rust it over time, and if it’s made from certain kinds of plastic, rubbing alcohol can break it down and warp it.

Obviously, since we’re talking about electric weed grinders, don’t submerge the whole device in ANY kind of liquid or it won’t worth next time you go to use it. If your grinder bowl is made out of metal, you can swab it, and the grinding teeth down with rubbing alcohol (or if this part is removable, soak the entire metal part in a bag of alcohol for maximum cleaning). If it’s plastic, you’ll have to try the same thing with hot water, best if it’s boiling, but be careful, use tongs etc etc.

How to make an electric weed grinder?

Making your own electric grinder requires a small motor, a battery, a couple of containers, and some sort of metal for the blades. It also requires a ton of patience and a willingness to putter around with electrical components. It can be done, for sure, and there are YouTube videos aplenty showing you how to make your very own but who has a small electric motor just lying around the house? Also, with so many great grinders out there, unless you are an engineering student or are a through-and-through DIY type, maybe it’s better to just buy one!

How to fix an electric weed grinder?

How to fix your grinder depends on what’s wrong with it. If the teeth aren’t able to move easily, try cleaning it (instructions above). If it simply won’t turn on, make sure it’s charged if it’s battery-powered and plugged in if it has a cord (we know, that’s basic advice but you’d be surprised how many times that’s the problem). If it STILL won’t work, check the manufacturer for any troubleshooting tips to try or perhaps a replacement if nothing else works. Keep in mind that you’re dealing with electrical parts so tinkering with it may not only void any possible warranty but it can also give you a jolt. We’re sure you don’t need us to tell you to be careful but be careful.
