The MESII VAST ENERGY 30000 is the most instrumented device in this batch: a 360° LED strip wrapped around the body, a dashboard screen styled like a speedometer, and four output modes you cycle through with a touch.

The dashboard, and what it actually reports

The screen shows battery level, remaining supply and the active mode, laid out like a mechanical dashboard rather than a row of numbers. That styling is cosmetic; the information behind it is the useful part.

On a 30ml device the supply reading matters most. After a month the level is invisible from outside, and without a figure the last quarter is guesswork rather than a decision you can make.

Four modes instead of one

Eco, Pro, Plus and Max run the coil at increasing output. Eco stretches the reservoir and keeps the vapour cool; Max produces the fullest cloud and spends supply fastest.

The two in between are where most use lands. Having four rather than two means the step between settings is small enough to feel, which is what makes choosing one meaningful rather than arbitrary.

The details that are easy to miss

A child lock disables firing until a short sequence is repeated, which matters for anything that travels in a bag. A stealth setting dims the screen and the light strip for use in a dark room.

Both are the kind of feature that sounds like padding until it is needed. The lock in particular is the difference between a device that can be carried and one that cannot.

Dual mesh and the draw

Two mesh coils share the heating, which keeps the vapour even as the reservoir empties and shortens the ramp-up before each pull. At this capacity that is most visible late, where a single coil tends to turn harsh.

Airflow is fixed and the device is draw-activated. The mode is the only variable, and the wheel of settings is where the tuning happens.

Charging an 800mAh cell

800mAh across 30ml means a handful of charges rather than one. USB Type-C on a standard cable, roughly an hour from flat, and no dock.

The screen makes the routine visible. Because output changes with the mode, the charge drains at different rates depending on where you leave it, and a percentage is easier to plan around than a coloured light.

Who it suits

It suits anyone who likes knowing where they stand: charge, supply and mode all readable, with a lock for carrying and a dim setting for quiet rooms.

It is less suited to someone who wants nothing to configure. Four modes and two toggles are options, and a simpler device does without all of them.

What the light strip is for

The LED band wraps the full circumference rather than sitting on one face, so the device reads as lit from any angle. That is a display decision rather than a functional one, and it is worth being clear about the difference: the light does not indicate anything the screen is not already showing.

Where it earns its place is a dim room. A device that is easy to locate on a table without turning a lamp on is a small convenience, and it is the kind of detail that decides which of two similar devices gets picked up in the evening.

That is the whole case for a lit body: it is useful in exactly one setting, and useless in the rest.

Buying and delivery

UseeVape supplies the MESII VAST ENERGY 30000 in single units and in bulk, with wholesale pricing applied as the quantity rises. Orders typically start at around ten units; the price that applies to your quantity is shown on the product page rather than fixed here, so it stays accurate when pricing moves.

Stock is held across European and overseas warehouses, and the dispatch location depends on live availability at the time of the order, so no specific country warehouse is promised in advance. Confirming the quantity and the option mix together is the quickest route to a dispatch date.

Questions buyers ask

How many modes are there?
Four: Eco, Pro, Plus and Max, cycled with a touch or a single press.

Is there a child lock?
Yes. A short repeated press locks and unlocks firing.

Does the screen stay on?
It activates on use and dims when idle; a stealth setting darkens it entirely.

Is the airflow adjustable?
No, it is fixed. Output is set by the mode.
