Available for $29.99 from Binoid

Binoid, a brand with a name that makes them sound more like a robot and less like a hemp company, is currently making the strongest delta-8 cartridge that you can get online.

Their Guava strain sits at an impressive 99% delta-8 THC mark. Guava is a fruit used often in the making of jellies, which fits because a cartridge this strong will have your brain and body feeling like a spreadable condiment. It’s also shocking that a brand like this, that pulls off a potency like that, charges only $29.99 a cartridge. Sometimes you don’t need to be a billionaire to go to the moon, you just need some Binoid.

Available for $35 from Harbor City Hemp

Harbor City Hemp, a Florida based brand with a catchy name and a punchy product, finds themselves as an intriguing contender in the fight for the strongest delta-8 cartridge.

Offering both CO₂ extracted and steam distilled cartridges, 16 different strains, and comprehensive lab reports to accompany their products, this is one of those companies that you can feel safe purchasing from. But strength is why you’re here, not strains or paperwork. And strength is something these guys have. Their most potent distillate came back with a 93% delta-8 THC concentration; which means you’re going to be 100% stoned after giving them a try.

4. Delta Extrax Delta-8 Cartridge

Available for $29.99 from Delta Extrax

Delta Extrax is offering a small line of delta-8 THC vape cartridges sitting in the 90-91% range. This is a company with mixed reviews, some people love what they make and some people say to yield caution. As previously stated; this is a potency list, so the fact that they test at 90% is why they’re on here.

Outside of that, their testing doesn’t include reports on pesticides, toxins, or heavy metals. Hence the yielding caution. There are six strains to choose from, they’re relatively inexpensive, and enough people have said they’ve enjoyed the effects. They could be worth testing, but for my money I’m choosing one of the above brands instead.

Pros & Cons


  • Affordability is the top quality
  • Fairly strong effects
  • Smooth vape


  • Incomplete lab results 
  • Small selection of only 6 strains
  • Does not ship to 12 states 
  • Reports of a “NyQuil” type taste

5. Delta-8 Cartridge

Very potent delta-8 THC vape cartridge

Available for $29.99 from is one of the hardest brands to write about because they named themselves after the damn product. Every article about them quickly turns into an Abbott and Costello sketch. Quirky name choice aside, this is one of the most surprising and effective delta-8 cartridges being offered.

Though lab results show testing at 84% Delta-8 THC, I’ve sampled this cartridge on numerous occasions and each time it holds its own, if not exceeds, the higher potency options. Don’t let the numbers fool you, this is a smooth and sweetly strong option. Few cartridges have relaxed me as much as their carts. These carts cost only $29.99, are chock full of cleanly tested ingredients, and will supply you with a deeply euphoric experience.

Pros & Cons


  • Sneaky strong potency
  • 84% delta-8 concentration plus 5% cannabis terpenes
  • Reputable COA’s 
  • Major anxiety relief effects 
  • Smooth tasting
  • Free of any cutting agents (MCT, Vitamin E, PEG, PG, or VG)


  • Cheap looking packaging 
  • Small product selection, only offering 6 strains
  • Does not ship to 11 states

Available for $39.99 from MoonWlkr

MoonWlkr has easily become one of the most recognizable names in delta-8 – continually pump out superb products with noticeable effects and that starts to happen. Their delta-8 cartridges are no different. The selection is small but the quality is noteworthy. Seven pages of clean lab results accompany each cartridge.

There’s no guessing with MoonWlkr, you know exactly what you’re getting. This is the type of vape where the effects will be quick, they start at the head and disperse evenly throughout the body. The one downside? At $39.99, for an 800mg cartridge, this is a very pricey product considering the same quality of product is available for cheaper.

Pros & Cons


  • 800mg delta-8 potency plus plant-derived terpenes and natural flavors
  • Reputable, big name brand with quality lab results 
  • Fast acting effects within puffs 
  • Vibrant packaging that stands out amongst competitors
  • Mind and body high
  • Clean ingredients, doesn’t use any cutting agents
  • Cartridge made with stainless steel and food-grade silicone


  • Priced way too high
  • Need to add more strains, currently offering only 4

Who are these max potency delta-8 cartridges for?

Max Potency doesn’t necessarily mean this is reserved for those with the strongest tolerances.

I’ve found that some of the cleanest products on the market, free of toxins and pesticides, have the highest delta-8 concentrations. It makes sense because with more delta-8 put into a product, the less cutting agents are needed. So when that high percentage of delta-8 THC pops on a lab result you know there’s a smaller chance of tainted ingredients. And with cartridges, you can take one puff and put them down.

So these are products anyone, even beginners, can experiment with. You choose how much you want, when you want it.

What’s the maximum strength offered for delta-8 cartridges?

The most potent delta-8 cartridge we could find online came in at 99% (990mg) delta-8 THC oil from Binoid. There’s a handful of others that sit in the 90% range, and it’s not rare to see credible brands coming in with 80% (800mg) concentration.

Numbers can sometimes just be numbers though. Cannabis is such a unique experience for so many. There are some 80% cartridges that have hit me harder than 95% cartridges.

What you want to ultimately look for is a clean product that’s been tested, then start sampling these and find which suits you best. Anything above 80% should, if legit, be able to produce notable effects.

Final Thoughts

If you’re looking for the strongest delta-8 THC vape cartridge, Binoid is leading the class with the highest grade of a 99% delta-8 THC oil vape. But with countless companies currently churning out clean, safe, and effective cartridges, this list will provide you with a wide range of choices to explore.

Vaping delta-8 is one of the best ways to not go overboard and take it puff by puff as the day goes on. With all these brands you have the choice to take a few puffs and move about freely, or hunker down, rip a plethora of pulls and melt into your favorite couch. That’s the beauty of a cartridge. You’re the conductor of your own high. And as the conductor, we’ve given you quite a few options to steer, so hopefully this list helps you find your best high.
