Voopoo Doric 60, what its 4.2 V output really allows

Sixty watts, 2500 mAh, a resistance range of 0.1 to 3.0 ohms. The spec sheet of the Voopoo Doric 60 lines up broad figures that shops copy without ever linking them together. Yet Voopoo publishes one figure that none of the pages we checked repeats, the device’s output voltage. Set against the coil fitted, it shows how much power the tube can deliver, what the battery supplies on each puff and how much firing time one charge holds.

Voopoo Doric 60, the answer in three figures

The Voopoo Doric 60 lists an output voltage of 3.2 to 4.2 volts. Taken at face value, that upper limit keeps 60 watts for coils below 0.294 ohm, since power equals voltage squared divided by resistance.

Above that threshold, the real ceiling falls quickly. It drops to 39 watts on a 0.45 ohm coil, 17.6 watts on a 1 ohm coil and under 6 watts on a 3 ohm coil.

The two coils supplied in the kit stay well clear of that limit. Their published ranges both top out at 3.46 volts, the square root of 12, exactly like the low values of the same maker’s PnP X range.

The official Doric 60 spec, figure by figure

The values below come from the page Voopoo devotes to the Doric 60. Dimensions and weight, missing from that page, are left out here.

Item	Value published by Voopoo
Battery	2500 mAh, built in
Power	5 to 60 W
Output voltage	3.2 to 4.2 V
Resistance range	0.1 to 3.0 ohms
Pod	PnP, 4.5 ml
Coils in the kit	PnP-VM5 at 0.2 ohm (40 to 60 W) and PnP-VM1 at 0.3 ohm (32 to 40 W)
Firing	draw-activated or button
Charging	USB-C, 1.6 A

The 4.5 ml figure is the one on the maker’s sheet. The page includes a TPD packing list, without stating that version’s capacity in its text. Under the Tobacco and Related Products Regulations 2016, refillable tanks sold in the UK are capped at 2 ml, and nicotine e-liquid at 20 mg/ml in bottles of no more than 10 ml.

Power is set on three levels shown by the colour of an LED. Neither Voopoo nor the retailers we checked give the wattage of each level.

What 4.2 volts allows, coil by coil

A wattage range only means something for the coil that receives it. The calculation below applies the maximum published voltage to common values from 0.2 to 3 ohms, then keeps the lower of the two ceilings, the voltage one and the 60 watt one.

Maximum power for each resistance

Figures are rounded to the nearest tenth of a watt.

Resistance	Power at 4.2 V	Effective ceiling
0.2 ohm	88.2 W	60 W
0.3 ohm	58.8 W	58.8 W
0.45 ohm	39.2 W	39.2 W
0.6 ohm	29.4 W	29.4 W
0.8 ohm	22.1 W	22.1 W
1.0 ohm	17.6 W	17.6 W
1.5 ohms	11.8 W	11.8 W
2.0 ohms	8.8 W	8.8 W
3.0 ohms	5.9 W	5.9 W

The threshold sits at 0.294 ohm, which is 4.2 squared divided by 60. Beyond it, the chipset no longer sets the maximum, the available voltage does.

A 3 ohm coil, bounded below by the 5 watt floor and above by 5.9 watts, is therefore left with a window of less than one watt. The 0.1 to 3.0 ohm range is accurate, but its upper end offers almost no adjustment.

A 3.2 volt floor that does not hold

The lower limit raises another problem. At 3.2 volts, a 0.2 ohm coil already receives 51.2 watts, while Voopoo gives 40 watts as the bottom of the range for its own PnP-VM5. Those 40 watts need 2.83 volts, below the stated floor.

As written, the two figures cannot both be right. The page does not say whether the 3.2 to 4.2 volt range describes the chipset’s output or the battery voltage, and 4.2 volts is also the voltage of a fully charged lithium-ion cell. Only the ceiling is used as a reference in our sums.

The two Doric 60 kit coils and the battery

The wattage set fixes the current flowing through the coil, then the current the battery has to supply. Voltages and currents are worked out at both ends of each published range.

Kit coil	Published range	Voltage	Current through the coil
PnP-VM5, 0.2 ohm	40 to 60 W	2.83 to 3.46 V	14.1 to 17.3 A
PnP-VM1, 0.3 ohm	32 to 40 W	3.10 to 3.46 V	10.3 to 11.5 A

On the battery side, take a nominal voltage of 3.7 volts and 90 per cent conversion efficiency, assumptions of ours rather than manufacturer data. Set to 60 watts, the circuit then asks about 18 amps of the built-in cell, against 12 amps at 40 watts and 9.6 amps at 32 watts. With the battery low, around 3.2 volts, those 60 watts call for nearly 21 amps.

Voopoo publishes neither the cell’s part number nor its discharge rating. The 18 amp figure therefore measures the load placed on it, without saying whether the cell handles it with headroom. To read that rating on a removable cell, our page on the 21700 battery and its runtime sets out the method.

What 2500 mAh means in firing time

Multiplied by 3.7 volts, 2500 mAh comes to 9.25 watt-hours. With the same 90 per cent efficiency, about 8.3 watt-hours reach the coil of the Voopoo Doric 60, close to 30,000 joules per full charge.

Wattage set	Total firing time	Three-second puffs
60 W	about 8 min 20 s	about 165
40 W	about 12 min 30 s	about 250
32 W	about 15 min 35 s	about 310

These times ignore the capacity a cell loses as it ages, standby drain and accidental firing. They give an order of magnitude, not a runtime stated by the maker.

The gap between the rows matters more than the values themselves. Going from 60 to 32 watts, with the matching coil, nearly doubles the firing time available on one charge.

Doric 60 Pro, the same electrical envelope on a different pod

The Doric 60 Pro keeps the figures the calculation rests on. Voopoo’s official page for it lists a tube 128 mm long and 26.1 mm across, the same 2500 mAh built-in battery and the same 5 to 60 watt output across three levels. Above all, it publishes the same output voltage, 3.2 to 4.2 volts.

What changes is the pod, which moves to the PnP X platform. Voopoo lists it at 5 ml, with a 2 ml TPD version, the only one that meets the UK cap. The kit comes with a 0.8 ohm and a 0.3 ohm coil.

Since the published voltage is identical, our maximum-power table applies to the Pro as well. The ranges of the PnP X coils we took apart also top out at 3.46 volts for the three lowest values.

FAQ

Five practical questions the Doric 60 spec sheet leaves open.

How do you change the power level on the Doric 60?

Three quick presses on the button open the level choice, and each further press moves to the next level. The LED turns white for the highest level, green for the middle one and blue for the lowest.

How do you switch the Doric 60 on or off?

Five quick presses on the button, either way. Switching the device off before slipping it into a pocket avoids an accidental button press.

How do you read the Doric 60 battery level?

After a puff, the lights above the button show the charge left. Three lights mean more than roughly two thirds, two lights a charge between one and two thirds, a single light less than a third.

How long does a full recharge take?

Voopoo lists USB-C charging at 1.6 amps. Divided by that current, 2500 mAh gives a theoretical minimum of about 1 hour 34 minutes. A lithium-ion cell finishes charging at a falling current, which makes the real time longer.

Do you have to press the button to use the Doric 60?

No. The tube fires when you draw, and the button stays available for manual firing, which stops as soon as you let go.

Voopoo Doric 60, power best read with its coil

On paper, the Voopoo Doric 60 covers 5 to 60 watts and 0.1 to 3.0 ohms. Read through its 4.2 volt output, the spec narrows, with 60 watts kept for coils under 0.3 ohm and higher values receiving only a few watts.

Both kit coils sit inside that envelope, with the same 3.46 volt ceiling as the PnP X range. Relating each wattage to the coil that receives it remains the most reliable way to read a pod spec sheet, the Voopoo Doric 60 as much as the models that followed it.
