They sent out the following for the purpose of review; six juices by Route 66 (review coming soon), six juices by Cheeky Monkey (check out my review by clicking here) and the iStick Pico 25 by Eleaf, which is what I have for you today.

Taking a look at the box

 The box came shrink wrapped, which was removed before images were taken. The main body of the box is green with a glossy finish and the internal box being white and with the same glossy finish.

On the front of the box you will find a photo of the device, the name of the device and a nicotine warning label.

On the base of the box you will find a list of contents, the distributors address and logo, some warnings in words and symbols and another nicotine warning label.

On the top of the box you will find the the company logo and the distributors logo. On the base you will find the different colour options for the device and an indication to which one is in the box.

On the sides of the box (which I’m not showing images of) you will find the company logo.

The iStick Pico 25 specifications:

  • Output Wattage – 1W to 85W
  • Powered by 1 x 18650 battery
  • Maximum charging current – 2A
  • Maximum output current – 50A
  • Screen – 0.91″
  • Modes – Variable Wattage/Temperature Control/Bypass
  • Resistance range: 0.05-1.5Ω (TC modes) 0.1-3.5Ω (VW mode)
  • Firmware Upgradeable

The device comes in six colour variations – Silver/Black, Full Black, White/Black, Blue/White, White/Greenery and Black/Red which is the one I have.

The size of the device:

  • Height including the tank – 114mm
  • Height without the tank – 70.5mm
  • Width – 50mm
  • Depth – 25mm
  • Height of tank – 45mm
  • Width of tank – 25mm
  • Weight – 96.5g

Taking a look at the MOD

The main part of the body is made from zinc alloy and painted black. The red part you can see on the device is a coloured plastic. Which is quite clear to see in the top two corner images.

On the top of the device there is the 510 connector with sprung loaded pin. Also there is the top cap to the battery chamber which has groves on it to give good grip, it also has a good thread. The bottom right image shows you the device without the battery cap and a battery.

On the front of the device there is a good sized fire button which is plastic and then there is the large screen and at the bottom there is a micro USB port. You can charge the battery through this port, but I would always advise to charge batteries externally. You can also use this port to firmware upgrade the device.

On the base of the device you will find the “+/-” button which is placed within an indentation. When the device is stood up on a flat surface you can not accidentally press it. You will also find seven ventilation holes.

The image below shows the tank broken down.

Taking a look at the Tank

The short and stocky tank comes with two large adjustable airflow holes which has stoppers when fully open and when fully shut.

The tank is top fill with a slide open top, there is the word ‘open’ embedded and a small arrow to aid you to push the top in the correct place. The top cap slightly clicks into place when opening and closing and needs a small amount of force to open/close. Which is a good thing as it won’t come undone whilst vaping. The hole is big enough to take a small unicorn style nozzle or pipette.

The drip tip is a chuff cap and is not 510 compatible.

Using the device

Placing the battery – screw off the battery cap, put one 18650 battery into the device and finally screw the battery cap on.

 Power on/off – Pressing the fire button 5 times will switch the device on, do the same again to switch off.

Stealth on/off – press the fire button and “-” button simultaneously when the device is
powered on to switch between Stealth On and Stealth Off mode.

Switch display mode – keep pressing “+” button and “-” button simultaneously for two
seconds when the device is powered off, the screen display will rotate 180 degrees.

Switch display interfaces – in power-on state, choose VW mode; keep holding “+” button
and fire button till the current interface flashes; when it’s flashing, press “+” or “-” button to switch among different interfaces; finally press fire button once to confirm the interface you chose.

Switch vaping modes – when the device is powered on, press the fire button 3 times in
quick succession, the device will display current vaping mode. Press the “+” or “-” button
to switch among VW, Bypass,TC-Ni, TC-Ti, TC-SS, TCR-M1, TCR-M2, TCR-M3 modes
and then press the fire button once or stay in the interface for about 10 seconds to confirm the vaping mode you chose.

Preheat function – in power-off state, keep holding “+” button and fire button till the M1
mode appears; press the fire button 3 times to ‘Power’, and press “+” or “-” button to
adjust the wattage of preheat; press the fire button again to ‘Time’, and press “+” or “-”
button to adjust the second of preheat or to turn off the preheat function.

Lock/Unlock resistance – in TC-Ni/TC-Ti/TC-SS/TCR(M1,M2,M3) mode, when the
device is powered on, keep pressing the fire button and “+” button simultaneously for two seconds to lock or unlock atomizer ‘base resistance’. The lock sign will appear when
resistance is locked and ‘Ω’ symbol will come back when unlocked.

The Setting of TCR Mode – when the device is powered off, keep pressing
the fire button and the “+” button simultaneously, then you will enter into the TCR
(M1,M2,M3) set menu:
1. Press the fire button repeatedly to choose among M1, M2 and M3 modes;
2. Press the “+” or “-” button to increase or decrease the TCR value according to the
material of the coil you use;
3. Keep pressing the fire button or stay in the interface for about 10 seconds to confirm
your setting.

I have listed the majority of the functions available, but this device will let you go into more detail within the different options – This device gives you so much control.

Thoughts and Conclusions

The first thing that really stood out for me was the user manual. A bit of a strange point to start on, but so many manuals are so badly written that you need a degree to decipher them. Not with this manual, well written and I actually know and understand the information being put across to me. Great manual.

On to the device itself, a great, solid little device that certainly delivers and packs a bit of a punch. It sits well in the hand. The control you have over its set up is vast, it has all your standard features that come with most devices, but there is a preheat function (which I really like). You can go to town when setting up the temperature control features, fine tuning the settings to exactly how you would like it.

The “+” and “-” button, at first I thought ‘why have you put it there?’. But after time and using it, it didn’t matter. In fact when going through the menu options I found the placing of the button helpful as I had the device on an angle to see the screen anyway.

I did check the temperature control, checking that it recognised the atomiser and performed well with an Aspire Cleito with 0.4Ω SS316L coil. (Doesn’t look as good as the Ello on this device, not that that matters).

Battery life is great, I was generally using the device between 40 to 50 watts and I found that the battery lasted a good day, which I definitely have no complaints about.

The tank, what a great little tank and really does produce some excellent vapour. In the box you get a guideline to the performance of the coils and for me the card is not right. For me the performance of the coils are opposite to what it suggests. HW1 coil was my favourite of the two delivering a good flavour and producing some good vapour. With the HW2 coil I found the flavour definitely muted in comparison and still produces some excellent vapour. The longevity of the coils for me was about two and half weeks which is pretty good. For me the HW1 coil is the better performer.

My thoughts on the look of the device, I looked online at the different colours  you can get and the Silver/Black one looks really smart. Personally I’m not keen on the plastic part of the body, I wish they had gone for a two part metal casing I think it would have looked a little more classy.

However, I think this is a really good little, stealthy device which goes into the pocket really easily. Though when you start to use it people are going to know about it. For me, with all the features that you get with this device I think that for a new starter they would be a little lost on. I think a device like this would be well suited to someone who was more intermediate to experienced. I think it is perfect as a secondary device something to have when out and about. That’s how I’ve been using it mainly.


  •  Solid, small device
  • Excellent User Manual
  • HW1 great coil, really good flavour
  • Great vapour production
  • Great battery life
  • Good top filling system


  •  HW2 if you like flavour, not a good coil
  • Drip tip not 510 compatible (Some people like to put their own drip tip on a tank)
