Review of the Helio Supply Smart Range Cartridge Battery

The Smart Range was sent to me for review. Well, actually, it was sent to me by the manufacturer to get my opinion of it, but I’ve chosen to do a review. This is an extremely small 510-cartridge vape device that fires as low as 1.2 volts and as high as 4.2 volts. It has an adjustable time-out feature and a 420mAh battery.


My first thought when pulling the Smart Range out of its box was how small it was. This device is super tiny; way smaller than I had expected. And that’s awesome because it takes up very little space in your pocket and also allows the device to be super discreet.

The specific measurements are 2.17″, 0.88″, by 0.90″

I think a lot of people will like this due to the size too, because one of my most popular reviews was a review of the Yocan Kodo, which people liked because of how tiny and discreet it is. I did that review in 2019 and I still get lots of comments about it today. The Yocan Kodo was cool, but the materials felt very cheap. The Smart Range feels much higher quality.

It has a triangular shape, which is also something I’ve never seen before. I wouldn’t say there’s any benefit to it other than that it’s a cool design. Although it feels good in my hands. And that shape might also help to prevent it from slipping and dropping out of your hand. But, really, I think it’s just a cool shape.

The casing is clear on the front, and the back panels have a space theme, sort of like looking into space and seeing thousands of tiny stars from very far away.

There is a 510 connection at the top. The front of the device has a screen, up and down buttons, and a firing button. On the bottom is a USB-C charging port.


The features are really important to mention because they make some big claims. They tout precise temperature control, the widest temperature range of any similar device on the market, optimal terpene preservation, and flavor retention.

So let’s go through some of those, starting with the precise temperature control. You can adjust the device anywhere from 1.2 volts to 4.2 volts. And you can adjust it in 0.1 increments, so you really do have a lot of precise control there.

I would also agree that this has the widest temperature range available, at least as far as I know. The 4.2-volt max is common, but I’ve never seen a cartridge vape go as low as 1.2 volts. Even in pre-heat modes, most devices run at around 1.8 volts.

So I think those two features—0.1-volt increments and going as low as 1.2 volts—contribute to the other two claims: optimal terpene preservation and flavor retention. You can fine-tune the voltage to exactly what you need for specific types of terpenes, even very low voltage levels, which prevents burning extracts and gives you the best flavor you can get.


You press the firing button five times fast to turn the device off and on. The screen shows your battery charge, the atomizer’s Ohm resistance rating, the voltage setting, a puff timer, and a puff counter. The screen is small, but everything is bright and clear.

If you press the firing button two times fast while the device is on, it’ll go into preheat mode. It runs at 1.8 volts for 10 seconds, and you can stop it anytime by pressing the firing button again.

You can clear your puff counter by clicking the firing button three times fast. And if you hold the up and down buttons for three seconds, you can lock or unlock the adjustment buttons. The lock prevents you from changing the voltage settings, but you’re still able to fire it and take hits.

This has a time-out feature that tells the device to shut off whenever you hit a specific number of seconds. It defaults to 10 seconds, but you can actually set it to as low as 3 seconds or as high as 30 seconds. This is a feature I’ve never seen in any vape device before so that’s really cool. To change your session time limit, press the firing button four times fast, adjust the time, and press the firing button or wait a few seconds, and that’s it. The time is set.

You can use any 510 atomizer that’s 0.8Ohm or higher.


The device charges using a USB-C cable, so it’s good to see that they didn’t go with a micro-USB. A micro-USB isn’t something you would expect from a new vape device these days, but the herb vaping industry tends to adopt technology a little slower.

They also include a small USB-C cable in the box. It’s very short at only 3 inches long, but I still think it’s nice that they included a cable because many companies don’t. It charges in only an hour.

The internal rechargeable battery is a 420mAh battery, which I love. That battery size has to be intentional, right? If not, that’s quite a coincidence. Either way, it’s funny. And I’d say that a 420mAh battery in a little tiny device like this is very surprising. That’s a big battery for such a little thing.

Final Thoughts

I think this is a very cool cartridge vape. The unique triangle shape is cool, and the case is nice, but what I really love about it is how small it is. This is super portable and discreet, which I know a lot of herb vapers will appreciate. You can adjust in 0.1 watt increments from 1.2 to 4.2 volts, so you have a lot of control there. And it charges using USB-C in only an hour. I think this is a great little device. I really can’t find anything wrong with it.

This was sent to me for review. You can get it from for only $25.00. But you might need to get it soon because they currently only have a limited supply of only 1,000 units. But maybe they’ll order more if it sells well.
