​Quick Answer: The 5 Best Electric Weed Grinders For 2019

​What Is an Electric Weed Grinder and What Are the Benefits of Using One?

For any type of weed consumption—vaped, smoked or edibles—grinding is a necessary step.

Cannabis buds contain THCA, a non-psychoactive chemical compound that transforms into the potent THC—tetrahydrocannabinol—when heated.

Grinding cannabis buds into smaller pieces—or even a fine powder—allows more heat to travel through the plant material. This means more THC is present, making it more potent.

If you’d like to learn more about THC and its benefits, this short video might be helpful.

Many cannabis users invest in an electric blender or grinder to make this process faster. These can be battery or power operated. They should be able to grind your weed in seconds at the push of a button.

Is an Electric Grinder Better Than a Manual One?

Electric or manual? This is an ongoing debate, and there is no right or wrong answer. Each as its advantages and drawbacks.

Advantages of Electric Grinders

Little Preparation Time

When using manual grinders, you’ll most likely need to break down your buds to make them fit between the grinder’s teeth. Most electric grinders have a large capacity, so no advanced preparation is needed.

Simply place your flower buds in the machine and turn it on.

Easy to Use

Normally, the push of a button will get your electric machine going. Manual grinders need some elbow grease, which can be a major obstacle to some people. This is especially true for those who use weed for medicinal purposes to treat arthritis.

Faster and Finer Consistency

Electric grinders tend to grind your weed much finer than a manual shredder would.

For a coarser grind, only press the button a couple of seconds. If you’re looking for a powder-like consistency, add a few more seconds. This is much faster than when grinding manually.

Are you a hobbyist who doesn’t love the powder-like consistency? This only happens when people grind their weed for too long—this can be easily adjusted.

Large Capacity

Most manual grinders will only shred a small amount of plant material at a time. The process needs to be repeated several times to get the quantity of weed needed.

The best electric herb grinder for weed can grind up to 3 ounces of weed at once. This means that you won’t have to shred your buds on a daily basis.

Portability Options

While some electric grinders feature a large capacity, others are extremely portable. Some are shaped like a pencil, easily fitting into a pocket or purse. A portable electric weed grinder is recommended if you travel often or are generally on the go.

Most portable manual grinders can take up more space and are less portable. This is especially true if you own a 4-piece manual shredder.

A Few Downsides

The major drawback of electric grinders is the ability to retain kief, that precious crystal contained in your buds.

Kief is a very gluey resin that easily sticks to any container. Electric grinders don’t usually come with a kief catcher. You’ll most likely wash most of it away when cleaning the device.

Electric grinders tend to be more expensive than manual ones, especially when operated with batteries.

Finally, some users report that they’re more difficult to clean and aren’t as durable as many manual grinders.

Which to Choose?

Electric or manual, this is really a matter of personal preference. How much do you want to grind at once and how do you plan to utilize your weed? If kief is important to you, then a manual grinder might be best.

Is your main priority to grind your buds as efficiently as possible? In this case, electric grinders are definitely recommended.

Different Types of Electric Weed Grinders

When shopping for the best electric grinder for weed, you’ll realize that you don’t necessarily need a specialized one. Some of the best ones are coffee and regular herb grinders, or salt and pepper mills. These also do a great job at shredding weed.

Portable Grinders

The best portable grinders are pencil-shaped and designed to fit the smallest pockets.

This type of grinder is ideal if you need to shred a small amount of cannabis on the go. They do come at a higher price point. If portability is a concern, however, it might well be worth the investment.

Coffee or Herb Grinders.

Although marketed to grind coffee beans, nuts or spices, these machines make fantastic weed grinders.

The best electric grinder for cannabis will be able to shred a large amount of plant material at once, as mentioned above—up to 3 ounces. A quick press on the start button and your weed will be ready in seconds.

Ideally, you want the ability to switch from a coarse to fine shred. Even without this extra feature, most coffee grinders come with a transparent lid. You’ll be able to watch the process, and control the consistency of your cannabis.

Keep in mind that coffee and herb grinders are not compact, and so not particularly easy to transport.

Electric Herb Mills

Electric herb mills are the types of devices mostly used to grind pepper or salt. These might be a great choice if you’re looking to spread your shredded cannabis on your coffee or toast.

In order to use electric herb mills, you’ll need to ensure that your buds are fully dried. If they still contain even a small percentage of moisture, they won’t shred properly and might jam your grinder.

Electric herb mills don’t come with a storage chamber for your ground cannabis. You’ll have to either store your shredded weed it in a separate container or use it straight out of the device.

Are you planning to apply your shredded cannabis straight from the herb mill into your food or drink? Remember that your weed only becomes potent after being heated.

In this case, before placing your buds in the grinder, heat your weed for about 20 minutes in the oven.

Battery Versus Power-Operated Grinders

Obviously, electric weed grinders need to be powered. This might be from a battery, a USB charge, or directly from a wall outlet.

Larger devices, such as coffee grinders, usually need to be plugged into an electrical socket. This means you won’t have to worry about spare batteries.

Other devices can be operated with batteries. They may not seem as convenient since you’ll always need an extra set of batteries available with you. But they are almost always smaller and therefore more portable.

The best electric herb grinder for weed, however, can be recharged using a USB port. This makes your grinder chargeable at home, but also in a car while on the road. Some even come with LED lights to let you know when it’s time to recharge.

Other Feature to Consider

You should now know what to look for when selecting the best electric weed grinder. Here are a couple of other factors to think about.

Size

Consider first how much weed you’re using on a daily or weekly basis. Pencil-shaped grinders are super cute and convenient. But the reality is that you’ll soon become frustrated if you need to grind four times a day.

Same goes for larger grinders. Putting a very small quantity of weed in a large grinder could mean your cannabis doesn’t shred properly. It might also take a lot of space.

Accessories and Extra Features

The best electric grinder comes with a soft brush for easy cleaning. If not, you might want to consider buying one separately.

Whichever grinder you decide on, think about selecting one with a transparent lid or window to see what’s happening inside. This will give you better control over the consistency of your weed.
