HorizonTech 100K Review: 100,000 Puffs From 40 mL
What a 40 mL, 1500mAh disposable gives you, and what buyers say it costs in size and charging.
7 min read
Key Takeaways
- HorizonTech rates the 100K at 100,000 puffs from 40 mL of e-liquid, which works out to 2,500 rated puffs per mL.
- The cell is 1500mAh with USB-C charging, and the maker fits a mesh coil behind an adjustable airflow.
- Buyers on ejuicedb.com describe the device lasting weeks, and the heaviest users report charging it every day.
- DirectVape lists 33 flavors, and nine of them carry the Slush name; the complaints on the sheet are about a flavor, not the hardware.
- Next to the 50,000-puff class, the 100K doubles the rated puff count, and buyers split on whether the size is a problem.
What the HorizonTech 100K Is
The HorizonTech 100K is a rechargeable disposable with a 100,000-puff rating, and that number is the whole point of the device. It holds 40 mL of e-liquid and runs a mesh coil on a 1500mAh battery, with USB-C to bring the cell back. HorizonTech made its name on refillable gear before it entered disposables, and the 100K reads like a maker that already knew how to build a coil. The size that comes with 40 mL is the trade-off to think about first, so this is a device for the desk and the car rather than a shirt pocket.

Battery and Charging
The 1500mAh cell is a large one for a disposable, and it needs to be, because 40 mL of e-liquid outlasts any single charge by a wide margin. HorizonTech charges it over USB-C, so the cable you already carry for your phone will do. The maker does not publish a charge time, and no buyer on our sheet gives one, so I will not guess at it.
What buyers describe is the rhythm of charging against a device that lasts a long time. A buyer on ejuicedb.com puts the cell on the right side of the ledger: "the flavors are great, strong and it lasts for weeks. The battery doesn’t die out fast either." Another buyer on the same site keeps the praise and adds the note I would expect from a heavy user: "They need charging everyday, but i like the amount of puffs and the look is nice too." Both reports fit a large cell driving a mesh coil hard, and a daily top-up is normal for a device you use all day.
E-Liquid and Flavor
At 40 mL, the 100K carries an unusually deep reserve for a disposable, and HorizonTech's rating works out to 2,500 puffs per mL. That is the maker's arithmetic, so treat it as a ceiling for short, light draws rather than a promise for long ones. What I can say from the facts is that 40 mL is the reason buyers describe this device in weeks rather than days.
DirectVape lists 33 flavors, and they fall into a few clear families. The Slush line is the largest at nine names, from Blue Razz Slush and Cherry Slush through Cola Slush, Mango Slush and Watermelon Slush. Mint and ice make up the next group, with Cool Mint, Miami Mint, Black Mint, Starlight Mint, Icy Mint and Mint Ice. The sour and candy names come next, including Sour Apple, Sour Straws, Sour Gush, Blue Rancher, White Gummy and Pink & Blue. The rest are straight fruit blends such as Triple Berry, White Peach Raspberry, Blueberry Watermelon and Strawberry Banana.
On taste the sheet splits by flavor rather than by device. A buyer on ejuicedb.com gives the Sour Apple one star: "Didn’t like the sour apple. Didn’t even taste like apples wish I could return it." A different buyer on the same site is lukewarm on the finish: "Good vape for the most part but it leaves a yucky after taste in my mouth." Both are notes on a recipe, and the Slush and mint groups draw no such complaint on the sheet before this post.
Draw, Airflow and the Screen
The airflow is adjustable, which matters more on a device this size than on a small one. With 40 mL to get through, you want to set the draw once and leave it, and a slider lets you move between a tighter pull and a looser one without changing devices. The coil is a single mesh unit by the maker's listing with us, which tends to favor a steady, even draw over the thick vapor of a dual mesh setup.
HorizonTech's facts with us do not list a screen, so I do not describe one as a specification. One buyer does. A buyer on vapesourcing.com writes that "tracking the juice level on the screen is super helpful for a device this huge." Two things in that sentence are worth keeping: the readout shows e-liquid level, and the device is large enough that the buyer calls it huge. Take both as one buyer's description and check the product page for the maker's current wording on the display.
What Buyers Say
The two themes buyers return to most are flavor and how long the device lasts, and the two tend to arrive in the same sentence. The ejuicedb.com buyer quoted above says it "lasts for weeks" and that the battery "doesn’t die out fast either," which is the combination HorizonTech is selling. Size is the point buyers disagree on. The vapesourcing.com buyer calls it huge, and a buyer on ejuicedb.com reads the same body the other way, with "nice flavor, great battery life and not too big and bulky".
The critical notes are about taste and about charging rather than about failure. The Sour Apple buyer and the aftertaste buyer, both quoted above, are complaints about a flavor, and the daily-charging buyer is describing what a mesh coil costs when it is run all day. Nothing dated before this post reports a dead unit or a leak, which for a device holding 40 mL is the fact I would weigh most.
Where It Sits
The 100K sits above our 50,000-puff class on the number that names it: 100,000 rated puffs against 50,000. It gets there with 40 mL of e-liquid and a 1500mAh cell, and the cost of those numbers is physical size, which one buyer calls huge and another calls not too big. If the puff rating is what you shop on and you do not mind the footprint, this is the one. If you want a device that disappears in a pocket, the 50,000-puff class is where to look, and you give up half the rated puffs to get there.
Pick It If, Skip It If
Pick it if:
- You shop on the puff rating and plan to use one device for weeks.
- You prefer Slush, mint or sour flavors, which make up most of the 33 names listed.
- You charge your devices at a desk or in a car and a daily top-up does not bother you.
Skip it if:
- You carry your device in a pocket all day and size matters more than capacity.
- You want a device that never needs charging between refills; heavy users report charging daily.
- You switch flavors often, because 40 mL is a long commitment to one.
The Verdict
HorizonTech built the 100K around one idea, and the numbers back it: 40 mL of e-liquid, a 1500mAh cell and a 100,000-puff rating that doubles the 50,000-puff class below it. The buyers we can cite agree that it lasts weeks and that the flavor holds, and the complaints are a flavor that missed and a daily charge, which is the cost of a mesh coil fed from a reserve this large. It is a big device for a specific person: someone who wants to buy one disposable and forget about the next for a long time. For that person it is the clearest choice in our disposables range.
