When it comes to a weed grinder, a weed grinder pen can offer many conveniences when it comes to grinding herbs. The ground herb is the end goal for herb grinder pens but the grinder and dispenser need to create a quality smokable herb that burns smoothly and increases surface area to increase potency. There are a variety of weed grinders that make the grade, but a pen grinder can offer true ease of use vs traditional weed grinders.

Best Electric Grinder Pen

For those that want convenience and electric power the electric weed grinder pen we recommend is the Rechargeable Electric Herb Grinder by LONZEN. This is a powerful grinder made from high-quality components.


With its steel blades powered with 24k RPM, it blazes through herbs in mere seconds. It also offers a viewing window so you can continually check on the efficiency of the pen grinder and its progress. This easy electric grinder is not your traditional weed grinder. It is so much more in that it places your grams of ground weed right into a smoke-able cone for you.

One thing we always look at when reviewing weed grinders that are electric is how long the battery life lasts on a single charge. The LONZEN rechargeable herb grinder meets the grade and lasts somewhere between 300 – 500 times before a new charge is needed, which is more than other electric grinders.

This electric grinder is also easily portable and can fit in just about any pocket or purse making it discreet. At 6 inches tall and just over an inch wide it is a bit bigger than others and grinds weed perfectly.

The electric weed grinder also comes with a 2-year warranty so you are covered if something breaks, a 30-day money-back guarantee in case you don’t like it, but we think you will. It has been well-received based on past customer reviews thanks to its helpful instructions included.

What is a Cannabis Grinding Pen?

A pen-shaped grinding tool is much like a traditional weed grinder but as the name implies it is shaped more like an ink pen. These types of weed grinders make it easier to dispense than a traditional herb grinder in that they have a cone-shaped dispensary outlet so you can easily fill a cone or a pipe fast and easy.

Traditionally a grinder pen is for those who enjoy smoking cannabis in joint or blunt form. By using a pen you have much more control with filling and grinding than other methods.


Depending on what kind of smoker you are, there is a perfect pen out there for you. From discreet grinding and filling to those that appreciate a perfect grind and cone every time, the choice is yours.


1. What are the best weed grinders to buy?

Choosing the best weed grinder can be difficult because of all the different options available. Weed grinders come in a variety of shapes and sizes, so it is important to consider your personal needs before making a purchase. If you are looking for an affordable option, then I would recommend purchasing a simple two-piece model as they are typically less expensive than more complex models with multiple pieces. However, if you need something that will last longer and work better over time, then opt for herb grinders with more features and add-ons.

2. Do they make electric grinders for weed?

Yes, electric weed grinders are available for weed. However, an electric grinder can be expensive. If you’re not looking for an electric grinder then a cheaper alternative would be using a manual grinder or even just rolling it up with your hands like in the old days!

3. What makes a good weed grinder?

A better way to use metal grinders is to use them as weed grinders that are home-grown. Many people pick these as the basis for grinding their cannabis. It is easy to keep clean, is sturdy, not exceptionally noisy, and is easy to transport. It also has a lock on the container, which helps cause it to remain closed.

4. Are Santa Cruz shredders good?

Of all the weed grinders I’ve used, testing with multiple weed samples, from damp and sticky to hard and dense, has confirmed the Santa Cruz Shredder’s capability to impart evenly fluffy trichome-rich herbal material. The herb is not mangled, and no trichomes come apart! Great enough for dry herb vaping, and its humidity is optimal for hassle-free smoking, as well.

5. Do you need to grind weed before putting it in a pipe?

It’s advised to cut back the flower using a grinder. One-hitters and small bowls are especially susceptible to breaking down cannabis with ground cannabis. Compressed air can flow more easily during the smoking process when the grind isn’t big.
