In this review, I will talk about the latest single battery mod called DRAG M100S from Voopoo. The main thing: 100 Watts, 510 connector, 18650/21700 and a nice design!

The recently introduced DRAG 4 mod turned out to be frankly excellent, but it has one drawback – its decent size. While writing a review of DRAG 4, I was thinking, why doesn’t Voopoo release a smaller device on the same board, for one battery, maybe even a 21700. And that’s what happened. Meet the Voopoo DRAG M100S.

I received a pre-production copy for review, which is noticeable by the SAMPLE sticker on the packaging and the engraving on the battery block itself. e-liquids in australia However, the likelihood that devices different from this one will go on sale is vanishingly small.

With this device, Voopoo designers decided to change the boxes we are used to for something new. Both the color scheme of the packaging and the way the product is presented have changed. Now you can see it through a transparent window and evaluate, so to speak, both the dimensions and the real color. The back of the box is occupied by the usual inscriptions: delivery set, sticker with authentication code and other legal and technical information.

Package

The ends contain a list of the main features, the logo and the name DRAG M100S on a foil backing with a clever design. They made a very interesting approach to sealing the packaging: now you have to tear off the tape from below and you won’t be able to get inside without damaging the packaging.

Interesting thing: before opening, the tear-off tape contains the inscription OPEN, and after opening JUST DRAG, although in my opinion, it was the second one that should have been taken upstairs, it would have been a play on words “Just drag” to open the package.

Inside, the entire delivery set is covered with a transparent plastic insert with names. Here you will find the mod itself, a tank with maintenance-free UFORCE-L TANK evaporators, a second bubble glass (not directly included) and a box with spare parts (USB Type-A to USB Type-C cable, orings for the tank and instructions in several languages, reminder about batteries and two replaceable evaporators).

Construction of Voopoo DRAG M100S

Review of the DRAG M100S kit from VOOPOO – appearance

No matter how offensive it may be for DRAG fans, there are practically no common forms in the new model with its predecessors. Except that the front side is very similar to DRAG 4, and all the “square brutality” has been lost. Even the most recognizable narrowings on the sides of the screen are almost invisible. Even the DRAG inscription on the entire body, which was also on similar models Drag X, Drag X Plus, Drag S and Drag S Pro, has disappeared.

The fashion style has become more strict and precise, clear and crystalline, which is facilitated by the clever engraving on the side surface, which shimmers in different shades, visually forming a pattern of three parts. The mod, despite its decent dimensions, does not look too big, at least in my steel color. For those who like more colorful solutions, you can take red, blue, bronze or black options.

The complete tank is the same everywhere: UFORCE-L TANK, I’ve already looked at it in detail twice (here and here), and therefore I won’t dwell on it any more.

DRAG M100S – color options

I’ll pay a little more attention to the color; it’s not monotonous, but made with a gradient from light at the bottom to dark at the top. The steel model has a noticeable bluish tint, which is clearly visible compared to pure steel buttons. Although judging by the pictures on the site, you can’t say so, but I admit that these are the features of my test sample. So if you don’t like such shimmer, take the black or bronze version, they are more classic. But the blue and red ones will also have “special effects”.

Review of the DRAG M100S kit from VOOPOO – appearance

There are essentially no decorations on the side surfaces, except for two iridescent inserts. There are two depressions characteristic of the DRAG line, but they are almost invisible, and all the inscriptions are small and have moved to the bottom of the device. The slightly protruding bar on the back of the case interferes with a comfortable grip at first, but you quickly get used to it. But what’s not easy to get used to is the rather slippery texture of these same linings. So, in the summer, when picking up a mod with sweaty hands, you will have to be more careful. Again, I recommend looking towards the black or bronze version, where the linings are made to resemble wood and may be less slippery.

Review of the DRAG M100S kit from VOOPOO – connector

The upper part of the mod can accommodate any evaporator with a diameter of up to an impressive 29 mm. And if you get used to the minimal overhang that does not exceed the dimensions of the mod, then up to 30 mm! The platform itself has a metal insert in the center, decorated with the slogan Spark Your Life and the name of the DRAG device. The central pin of the 510 connector is spring-loaded, but the steel platform is practically not raised above the base, so with large tanks or drips, be prepared for scratches on the paint.

Battery Cover

The entire lower part is occupied by the battery compartment cover. The opening mechanism is concentrated in a round piece with a beveled side. To open, you need to move it to the side, in the direction shown by the arrow. This is not the most convenient activity, and regularly removing the battery will be stressful, and possibly fraught with rapid breakdown of the locking mechanism. So although I usually recommend charging batteries in external devices, in this case I will try to convince you to charge through the standard connector inside the mod.

Under the cover you can see the negative contact and not see the holes for venting gases. The two holes near the contact lead nowhere; when you look at the closed cover, this immediately becomes clear. Recently, more and more manufacturers have neglected this aspect of safety. On the other hand, there are no o-rings here, so you can safely forget about water resistance too. But perhaps this was done precisely to remove gases in case of problems with the battery.

Supported batteries Review of the DRAG M100S kit from VOOPOO – battery installation

The mod can work on both 21700 and 18650 format batteries; for the latter, the kit includes a plastic adapter cup. Batteries are inserted with the plus side inward. When using 18650 cells, I recommend placing some kind of sticker on them, so you can be sure that they will not rattle inside the adapter due to their smaller thickness.

Review of the DRAG M100S kit from VOOPOO – charging process

Although the manufacturer promised a charge current of up to 2.5 Amps, I was unable to overclock the mod to more than 0.6 Amps on a 21700 Samsung 40T and 18650 Samsung 30A. On Murata VTC6A banks it was possible to increase the current to 2.2 Amperes, but only on three of the four available, the last one stalled at charging with a number of 0.06 Amperes. The LG HE2 mod battery refused not only to charge, but also to work on it at all. Why? It’s not clear, I’ll check with professional chargers if I can.

Screen and control of Voopoo DRAG M100S

The group of controls and screen are almost identical to those in DRAG 4, only the lock switch has moved from the top position to the bottom, almost right next to the USB Type-C port for charging. All the buttons are not marked in any way, although it is intuitively clear that the largest one is FIRE, the top one under the screen is “+”, the central one is small “-”, and the bottom one is not a button at all, but a switch.

The buttons themselves are metal and do not rattle at all even with vigorous shaking. They are pressed clearly, with a characteristic quiet click, and for convenience they have small indentations.

Interface and control

The mod is turned on and off by pressing the Fire button five times. Immediately after activation, the board is in the “smart” SMART mode, which automatically selects power depending on the resistance of the evaporator. At the same time, the maximum power is limited to only 80 Watts, and it is changed using the lower buttons in 1 Watt increments.

The screen displays a standard set of information:

Power/temperature

Mode name

Battery charge scale and percentage value

Voltage, resistance and duration of the current puff

Number of puffs

Voopoo DRAG M100S Menu

Simultaneously pressing the “+” and “-” buttons opens the device menu:

MODE – hovering mode.

SMART – the “smart” mode described above.

RBA – power limited to 100 watts, designed for use with serviced evaporators.

ECO is a variation of the SMART mode, but provides longer operation on a single charge, something around 10% according to the manufacturer

TC – select one of four thermal control modes: nickel, titanium, stainless steel 316 or stainless steel 430. In this mode, simultaneously pressing Fire and “-” switches the temperature display in Celsius or Fahrenheit. And by simultaneously pressing Fire and “+” you can set a power limit from 5 to 80 Watts.

SWITCH – select the operating mode of the lock switch.

Complete blocking of all keys (locks).

Completely turning off the device and instantly turning it on (Power).

Locks only the power change keys (W).

PUFF RESET – reset the puff counter.

ABOUT – information about the chip and some Level Code.

COLOUR – select interface color.

Classic is the most pleasant.

Green.

Pink.

Purple.

Yellow.

In the DRAG 4 review, I complained that the GeneTT 2.0 chip slightly cheats and underestimates the power on the coils. We’ll definitely check this version of the board as well. Let’s calculate the current strength (I=U/R), then the real power through it (P=I2*R). You can calculate without calculating the current strength (P=U2/R), but the numbers will be the same, and I calculated the current strength for control and safe use of batteries, not all of them work in such modes.

Input values: resistance 0.06 Ohm, set to 100 Watts and get live 2.6 Volts on the screen.

Current strength: 2.6/0.06=43.3 Amperes. Power 43.6*43.6*0.06=112 Watt.

Let’s double-check using reasonable values: the resistance is the same 0.06 Ohm, set it to 50 Watts and get 1.96 Volts on the screen.

Current: 1.96/0.06=32 Ampere. Power: 32*32*0.06=61 Watt.

All! I take my hat off and have no more questions.

Total

Conclusions will be extremely short. If you need a board that doesn’t underestimate power, and you know how to realize its potential, purchasing the DRAG M100S will be a great solution. The ergonomics are good, at least it’s easy to get used to. The controls are quite simple and not overloaded; there is even thermal control for fans. Mechanical locking with three modes is generally an excellent feature, but if it learned to switch the screen to stealth, it would be absolutely wonderful. It’s just worth understanding the reason for the incomprehensible leapfrog with charging batteries in fashion. Well, or just use an external charger, hoping that the battery compartment cover won’t fall off in a month.
