Eleaf iStick Pico X Kit Review

Eleaf iStick Pico X Kit

Eleaf sure does know how to squeeze every variant out of the Pico line, their newest release is the Pico X. Just like the original Pico, it’s a single 18650 battery mod which can power up to 75 Watts.

The Pico X comes in a more lightweight, compact chassis. It has a rubberized finish, with grippy contours for extra ergonomics.

It also comes paired with the Melo 4 (D22) tank.

The Pico X is available in 5 colors: Silver, Black, Green, Blue, and Red.

The Good

Lightweight, ergonomic, good build quality, great performance from new mesh coils.

The Bad

Only fits 22mm atomizers, only 2ml juice capacity.

The Bottom Line

It’s another no thrills upgrade to the Pico line, that doesn’t bring much new to the table. However what it does bring are worthwhile and practical changes. The new lightweight plastic frame is incredibly comfortable, and the Pico X pairs well with the Melo 4. The new EC-M coils deliver good flavor and performance.

Eleaf iStick Pico X Kit

I know Eleaf have released so many Pico’s over the last few years that it’s becoming difficult to tell them apart and even to name them for that matter.

I’m not sure I entirely agree with this latest release being called the Pico X. I think using the letter ‘X’ tends to lend itself to something with an ‘X’ factor or more top of the line.

However, the Pico X is quite simple just a lightweight more ergonomic version of the original. They should’ve called it the Pico ‘P’ for its plastic frame…..(now you know why I don’t have a job naming products).

It’s been a while since a held an original Pico in my hand, but I can tell you for sure the Pico X does feel completely different even if it’s pretty much the same device.

Eleaf has ditched the zinc alloy frame and replaced it with a rounded plastic one. They have also paid attention to detail of the contours of your hand, and how it rests on the device while using it. The body has gentle swooping curves to match your grip, and even the fire button has a perfect slant to it.

However don’t be fooled by thinking this is a flimsy plastic device, it still feels solid in the hand. It also has that excellent rubberized finish which makes it feel even more pleasant to hold.

As for the design layout, everything remains the same. Unfortunately, the +/- buttons remain on the base of the device, and it has exactly the same threaded battery cover protruding from the top of the device.

Due to the Pico x’s compact size and battery cap design, the largest atomizer you can fit is a 22mm. Anything more substantial will collide with the battery cap.

Apart from the new lightweight frame, the most significant change with this kit comes with the included Melo 4 tank, and it’s mesh coils, which we will cover below.

Build Quality

Even though the Pico X is a plastic device, it still feels incredibly solid. There are no points where the plastic feels flimsy or gives in when you push it.

All of the buttons have a nice click to them, and there is no rattling whatsoever.

For a plastic device, I have no complaints about the build quality; it’s very good.

The Pico X is not only far lighter than any other Pico, but it’s also a little more compact than the original.

It measures in at 112mm high, 50 deep and 31mm wide with the Melo 4 tank attached, and only 73mm high without the tank. It also only weighs 65g without a 18650 battery inside.

The Pico X comes with all of the features you’d expect from an Eleaf device.

There’s temp control for SS, Ni, Ti, and three TCR memory modes in addition to a bypass mode.

There also a preheat option, which allows you to enter the power and duration of the preheat.

A single 18650 battery powers the Pico X, therefore, it has a maximum output of 75W.

It does have a micro-USB port for charging and firmware upgrading. However, there’s no fast charging on board, but it does charge a little over 1amp.

The Pico X has a 0.69-inch display. It’s quite a basic screen and can be quite cramped at times, but it does have good brightness levels.

Operating the Pico X is pretty much the same as any other Pico mod by Eleaf, so check out our detailed reviews on the Pico S or Pico 21700 for more operating details.

Eleaf iStick Pico X Kit - Melo Tank

The Melo 4 tank has been around for a while, but Eleaf has managed to adapt it to recent trends in vaping, by providing some updated coils included a mesh coil.

The Melo 4 has adjustable dual bottom airflow, and rarely seen in a sub-tank comes with a 510 drip tip. It has a top slide to fill system but only comes with a 2ml capacity.

The previous iterations of the Melo 4 if I remember correctly had a somewhat awkward small button you had to push to release the top fill system.

This version is the standard slide to fill which has a small arrow for indication on where to push. It works well and has the right resistance on the mechanism.

It doesn’t have the largest fill port but can comfortably accommodate most bottle size.

The Pico X ad Melo 4 comes with two coils included, which are both their new 0.15ohm EC-M coil.

This is a mesh Kanthal coil which is designed to operate at 30-75W. At the lower end of that wattage, you will have a slightly cooler vape and less vapor production.

I found they worked best at around 50-55W which is about perfect for a single 18650 mod. Any higher than that and you’d be draining that battery pretty fast.

It’s good to see the Melo utilizing mesh coils, and they perform really well, producing a decent amount of vapor with good flavor.

I’m actually struggling to tell the difference in performance between mesh coils these days, and the EC-M are as solid as they come.

The Pico X mod performs exactly as expected. It’s a solid no thrills mod that does the job it sets out to do as a compact single 18650 device.

It has plenty of features, but as always I found it works best in wattage mode. I did try TC with another tank, and it worked fine, but if you are a TC vaper then you probably already know there are better devices for that.

However, as the Pico X comes paired with the Melo 4 kit and Kanthal coils, it’s perfect to run in wattage mode. They also matched exceptionally well, and the new EC-M coils do give this entire kit a lift.

As a simple sub-ohm style kit, the Pico X and Melo 4 deliver on usability and flavor production in an excellent ergonomic package.

Battery Life

Obviously, this is going to be dependant on what wattage you are running the Melo 4 at, and which 18650 batteries you are using.

However, there were no glaring problems with battery life for me. It seemed very efficient for a single 18650 primarily running at 50W.

Good Vibes

  • Ergonomic
  • Compact
  • Lightweight
  • Easy to use
  • Rubberized finish feels good
  • Good build quality
  • Pre-heat settings
  • Solid performance
  • Good flavor from Mesh coils

Bad Vibes

  • Can only fit 22mm atomizers
  • Tank only 2ml capacity


Eleaf iStick Pico X Kit

It’s Eleaf, and it’s another Pico, so you could’ve probably guessed the overall verdict before we even started.

The Pico X may not have anything that really makes it stand out from the competition, or over previous Pico’s for that matter.

However, as a combined kit with the Melo 4, it is very good. It’s also without a doubt one of the most ergonomic and comfortable single 18650 devices to use.

It’s an incredibly affordable, lightweight kit that delivers on flavor and performance. As with most of the Pico range, there’s really not much to dislike.
