Reviewer comments on business characteristics

Eleaf advances its pawns with consistency, evidenced by this evolution to 100W, which can now be upgraded to deliver 120 (announced "on paper"), with the V1.10 here.

The latest-born (the Pico has just released) from the Chinese manufacturer, after 20 boxes, 30, 40, 50, 60W, offers the best of existing technology for a safe, controlled and sustainable vape, it adopts the fire bar, which replaces the button switch, already present for a few months on the recent XCubes from Smoktech. It offers 3 modes of vape: VW, TC, mechanic (bypass) protected.

We will detail below the other options of this box, but already we can say that for the asking price, it's a good deal. The manual is in French, the batteries are not provided, you will care to dedicate two identical 18650 batteries, new and at least 25A to your box, for good performance in complete safety.

It is however a material of a relatively large size which will probably repel many of our sisters, used to the previous models, finer and much better adapted.

Reviewer's comments on physical characteristics and perceived quality

The shell and lids are aluminum, covered with a good paint that seems resistant to shocks and other scratches, (to the extent that you do not throw it on the ground and do not intend to rub it heavily on an abrasive surface, it's okay without saying). The lids are held by magnets that give them a very good performance once closed. Five heat dissipation vents are visible in the upper part, in the center, before the arrival of the positive pole of the batteries, against the chipset.

The top cap features a stainless steel 510 connection with an air intake function and a two-position mechanical lock (lock) to prevent inadvertent firing, all the easier to produce in view of fire system. The brass positive pin is floating.

The bottom cap has five small venting vents and a micro USB port for charging via a computer.

The set is 94mm long and 23mm thick, the width is 52mm, the sides are rounded in half circle of 23mm in diameter. It is comfortable enough for the grip, but the coating is not anti-slip, it is better to hold it firmly.

The Istick of the test is white and does not leave visible fingerprints, the function fire bar (firing bar = cover) is active on the upper part of the box, its stroke is short and pleasant.

The settings part and the screen are located on the inside of a flat, transparent, smoked plastic cover. The buttons float a little in their home and that is understood. The screen measures 17,5mm on 4mm, it is protected, quite visible and remains discreet.

Reviewer's comments on functional features

The usual security features are in the menu of features, I will not return, the box cuts after ten seconds of pulse.

You can choose to vape without the screen, in "stealth ", when you have finished and locked your settings, to increase the autonomy of your batteries. Simultaneously press the bottom button and the fire bar. To lock the settings (box lit), simultaneously press the [+] and [-] buttons 2 seconds the display will show "Lock" and a small padlock will appear next.

lock settings

You will notice three buttons on the adjustment part of the Istick. In addition to the classics [+] and [-], another rectangular button at the bottom of the case made its appearance, it's handy since it allows you to switch between modes is access to the menu of features.

4 setting

To invert the screen direction, (box off), simultaneously press the [+] and [-] buttons 2 seconds, the display rotates by 180 °.

To go from one mode to another press and hold down the rectangular button at the bottom, you will have access to the following modes: VW - Bypass (protected mecha) - TC Ni - TC Ti - SS TC - TCR (Temperature Resistance coefficient) M1 - TCR M2 - TCR M3. note that the range of resistance values ​​from 0.1 to 3.5Ω corresponds to VW / Bypass modes.

As Meca modes, TC and VW have no secret for you, I will detail the operations to be performed in TCR mode.

3 setting

First of all we have to make sure that the resistance value of our assembly is in the range 0,05 - 1,5 Ohm; (beyond 1,5 ohm, the box automatically switches to VW mode).

The box must be off. Press the [+] and the firing bar simultaneously, you enter TCR mode, the first is the M1, to memorize a first ato setting. To select an M, press the [+] or [-] buttons, to confirm the selected M, press the firing bar.

To increase or decrease the TCR value of your choice, it is with the [+] or [-] buttons. To confirm the setting press the firing bar (I change a little) or leave in the state for ten seconds until the electronics is fed up and decides to take into account your last position (eg in SS mode ).


As also the record is in French, I will just confirm the alert messages, and invite you to read it when you operate your settings.

  • No atomizer or short circuit = " Atomizer Short "or" No Atomizer »
  • Battery under 3,3V (each) = " Lock », You must reload (or replace the acus) to unlock.
  • « Temp Protection »Relates to the coil temperature (TC Ni, Ti, SS, M1, M2, M3 modes) and warns you that it exceeds your settings.
  • When the device has a little fever, the box cuts and displays Device Too hot ". Patience, no antibiotics, remove the batteries instead and let him breathe fresh.

We did the trick quickly but essential, to begin to handle the beast as it should, it is done quickly.

Reviewer's comments on conditioning

A cardboard box in the colors of the brand which contains, on the upper floor, the box in its housing of semi-rigid foam.

The floor below is provided with the instructions and the USB / microUSB charging cable. That's all, it's enough and you can flash the QR code (on the back of the box) to go to the Eleaf website, check the authenticity of your purchase, and update the firmware.

Reviewer's comments on the use of the product

If from 1 to 50W the regulation dispenses rather well the powers required, it is not the same from 75W, where we can see a shift between the actual output values ​​and those displayed on the screen. Below, a table summarizes the percentage gaps of the values ​​tested, with 3 typical resistance values.

efficiency of regulation

This being so, the box is very reactive, the stable signal and its fairly precise settings, the resistances of my atos have been correctly evaluated.

The mechanical locking function of the fire bar is effective. I regret a little the position of the charging module and its output under the box, but I do not advise to use it systematically, a dedicated charger will be much more suitable and preserve the life of your batteries (only flat top in the Istick).

This box has, as they say, fishing! It is more designed for the sub-ohm than for the high resistances. Beyond 1,5Ω, the first 2 seconds will surprise you, as the Istick 100W has a tendency to boost from the start, it follows a brutal heating / coils and not necessarily a pleasant flavor rendering, while on the contrary to 0,3 ohm this boost is beneficial to avoid the lag.

All in all, it's good material, inexpensive and, I hope, is expected to last.
