HyperBar BE70K Review: 70,000 Puffs From 30 mL, Read From the Specs
The largest battery on the channel at 1200mAh, under the second-largest e-liquid capacity
4 min read
Key Takeaways
- HyperBar rates the BE70K at 70,000 puffs from 30 mL of liquid, the second-largest e-liquid capacity of any disposable on the channel.
- The battery is 1200mAh, the largest cell of any disposable we list, and it charges over USB-C.
- A dual mesh coil, adjustable airflow and a screen round out the body; the strength is 5%.
- The channel lists 10 flavors, and every figure in this review is the maker's rating as the catalog carries it.
Every number in this review is HyperBar's rating as the catalog lists it on August 19, 2026. Nothing was bench-tested, weighed or timed; the point is to read the specs the way a shelf tag would, so you know what 70,000 puffs on 30 mL means next to the devices beside it.
The HyperBar BE70K has been on the channel since July of last year. The spec table comes first, then the parts of the device one at a time, then a plain pick-it or skip-it call.

Puffs and Liquid
The headline is 70,000 puffs, and the number under it is 30 mL. On the channel only the HyperBar MX120K carries more liquid, at 40 mL for a 120,000-puff rating. Everything else we list sits below 30 mL, including the Lost Mary MT35000 Turbo at 18 mL for 35,000.
In use, 30 mL is a long stay on one flavor. If you finish an 18 mL device and wish it had kept going, the BE70K is built for you. If you change flavors every few days, 30 mL will outlast your interest in it.
Battery and Charging
The BE70K's 1200mAh cell is the largest battery on any disposable the channel lists. The MX120K, its bigger sibling by liquid, carries a smaller 1000mAh cell under a larger e-liquid capacity, and the MT35000 Turbo carries 1000mAh under its 18 mL. So the BE70K is the HyperBar that goes longest between charges, and the only one where the battery is the bigger number in its pair.
Charging is USB-C, the same cable as a phone. The screen on the front shows the state of the battery, so you plug in when the readout tells you to rather than when the draw goes weak.
Draw and Coil
The coil is a dual mesh, the same coil type the catalog lists on most disposables in this class. The airflow is adjustable, so you set the draw rather than taking the one the maker chose. Open it for a looser pull, close it for a tighter one; the setting is yours to change at any point in the 30 mL.
Against the MT35000 Turbo, which has fixed airflow, that is the one control difference. Against the MX120K, there is none; both HyperBar devices give you the same dual mesh coil and the same adjustable draw.
Build
The body is a tall rectangle with the screen on the front face. The screen reports the battery and the liquid, which on 30 mL of e-liquid matters more than it does on a smaller device, because you will own this one long enough to lose track of where you are in it.
Heads up: a device that carries 30 mL and a 1200mAh cell is not a small object, and the catalog carries no weight figure for it. If pocket size is the first thing you shop on, read the dimensions on the product page before you pick it.
Flavors
The channel lists 10 flavors of the BE70K, all at 5% strength. No flavor was tasted for this review, so there is no ranking here and no claim about which one lands; the flavor tiles on the product page name each one, and the device is the same under all 10. Pick by the name you already know you like, since the hardware will not change your mind either way.
Pick It If, Skip It If
Pick the HyperBar BE70K if you want the longest stretch between charges of any disposable on the channel, with a 1200mAh battery on 30 mL and a 70,000-puff rating. Pick the HyperBar MX120K instead if liquid is the only number you care about, since its 40 mL and 120,000-puff rating beat the BE70K and it accepts a smaller 1000mAh cell to get there. Skip the BE70K if you rotate flavors often, because 30 mL of one flavor is a long commitment, and the Lost Mary MT35000 Turbo at 18 mL is the shorter one.
The BE70K is listed under HyperBar on the channel, on the 50,000-puff disposables shelf.
