The 5 best electric and automatic weed grinders

Table of contents

The number one way to take your weed kit to the next level is to upgrade from a manual grinder to an electric one. A rechargeable, battery-powered grinder pumps out freshly ground bud at the push of a button, all without the tedious twisting and turning of an always-too-sticky manual grinder.

Electric grinders for weed are well worth the investment for the time and hassle they save you. Plus, many come with bonus features—like automatic rolling. So if you’ve upgraded your daily routine with a blender and a coffee maker, why wouldn’t you also upgrade to an electric grinder?

What is an electric weed grinder, and what do you use it for?

An electric marijuana grinder is a small device that breaks down large cannabis buds into a fine, fluffy grind—a consistency ideal for rolling into a joint or packing into a bowl. 

Instead of working away, twisting with a manual hand grinder, the electric version performs the same task automatically thanks to rechargeable batteries. 

What makes a good weed grinder?

A weed grinder, electric or not, has a single purpose—to produce perfectly ground up cannabis with minimal effort. So if you are shopping for an electric grinder, that’s the number one goal.

But, you’ll likely also want one that’s easy to clean and has a long-lasting battery. Depending on your budget and personal preferences, you might also want to take advantage of other features, including easy pollen collection, cone filling combo, or in-device storage.

Where is the best place to buy an electric weed grinder?

If you aren’t shopping directly with online headshops, like Grasscity or Smoke Cartel, Amazon is one of the best places to find a large selection of grinders. 

What’s more surprising is that electric weed grinders on Amazon are often listed at better prices than will be listed on the brand’s own website and come with a free shipping option too.

Just keep in mind that due to Amazon’s corporate policies, you’ll often find cannabis accessories listed as “herb and spice” grinders rather than as “cannabis” or “weed” accessories.

Why invest in an automatic weed grinder?

Why would you want to invest in a battery-powered grinder over a cheap $5 manual one? Above all else, electric grinders shave down on the time and labor required to roll that next joint or pack that next bowl. No more tiresome twisting back and forth—it transforms the process with a single button.

Plus, packing cones and blunt becomes astronomically easier with the dispenser caps included on some grinders, like the LONZEN and the Quant.

There are also mobility considerations. A resinous manual grinder can be challenging, even for those who don’t struggle with mobility issues. But if you have lost strength or dexterity in your fingers, this process is near impossible. Electric grinders ensure you can still access medicine, even if you experience limited mobility.

Can you use an electric coffee grinder or a blender  to grind weed? You absolutely can, but consider how difficult it will be to clean out the sticky crystal from your blender or coffee grinder. More importantly, grinders designed specifically for cannabis produce a fluffy flower consistency rather than a fine, dry powder. In other words, they

A final note: make sure to clean your grinder 

Just because you’ve gone electric doesn’t mean you can skip the cleaning routine. Your electric cannabis grinder needs as much care as manual ones, as sticky crystals can build up and slow down the mechanisms.
Learn how to clean your grinder properly. Typically, you can use isopropyl alcohol and a Q-tip to carefully clear out the resin from within the chamber and blades. Most electric grinders have a safety stop to ensure exposed blades won’t accidentally turn on when the machine is open. However, it’s best to revert to the user manual, as every electric grinder will have slightly different protocols.
