The AIVONO AIM FATMAX 50000 pairs 30ml of reserve with a dual smart display and an 800mAh cobalt cell — a device built to be read as much as used.

Two displays, two answers

The dual screen shows charge and remaining capacity as separate readings. On a 50,000-puff device that is less a luxury than a necessity: nobody keeps count across weeks of use.

It also settles the question that ends most large devices early — whether a weak draw means the battery or the supply.

Cobalt cell, thirty millilitres

An 800mAh cobalt cell holds its voltage longer than the cheaper chemistry used in much of this bracket. The practical effect is that the draw at the halfway point feels like the draw at the start.

Thirty millilitres is a generous fill for this rating, which is why the device finishes rather than running dry early.

Dual mesh

Two mesh coils share the heating load, keeping the vapour even across weeks of use. That is what stops the burnt edge that single coils develop near the end of a long reservoir.

The draw is tuned for mouth-to-lung: some resistance, a warm vape, and enough vapour to feel substantial without being a cloud device.

Figures reflect the current product record. Puff counts are manufacturer ratings and vary with draw length and frequency.

Charging and storage

Charging is over USB Type-C on a standard cable, and the display tells you when the next top-up is due rather than leaving it to a weakening draw.

Keep it upright and away from heat. A device held for weeks spends long enough in whatever conditions you store it in for that to matter.

Reading the display

Two numbers, two decisions, and both are worth knowing before the device feels wrong. Charge low and capacity fine means plug it in. Capacity nearly out and charge fine means the device is coming to the end of its life.

That is all the display is for, and on a 50,000-puff device it is the difference between finishing it and abandoning it half full.

Why the cobalt cell matters

Cobalt chemistry holds voltage better than the cheaper cells used across much of this bracket. The practical effect is that the hundredth draw feels like the first, rather than fading as the charge drops.

It also means fewer top-ups across the life of the device, even at this rating.

Care and end of life

Keep it upright and away from heat, particularly once the reservoir is half gone. There is nothing to refill and nothing to clean.

Towards the end the vapour thins slightly and the draw warms. Check the capacity reading before assuming a fault, because the answer is usually on the screen rather than in the vapour.

How it feels to use

Draw-activated, with no button and no menu. The only interaction is the inhale and the occasional charge, and the display does the rest.

In the hand it is a substantial device — 30ml and a cobalt cell are real weight — which suits a desk or a bag rather than a tight pocket. Set it down upright between sessions and it behaves; leave it on its side in a warm bag for a week and any device of this type will start to seep.

The end of the reservoir

Towards the end the vapour thins and the draw warms slightly. Check the capacity reading before assuming a fault: on a device this size, the supply usually runs out before the battery does.

Questions

What do the two displays show?
Charge and remaining capacity, as separate readings.

Is it rechargeable?
Yes. The 800mAh battery charges over USB Type-C.

How long does it last?
Weeks at a moderate pace. The 50,000 figure assumes short test draws.

How does the draw feel?
Tight and warm, in the mouth-to-lung style.
