In for review this week is another mech, with a silhouette that has become pretty familiar over the last year or so.Dovpo Signature Mods Clutch X18 Product ShotIt’s the Dovpo Clutch X18 by Signature Mods, a dual battery version of the very well received 21700 Clutch.

What Can We Expect From The Dovpo Clutch X18 by Signature Mods?

First things first! This is a dual battery mechanical mod, as such there is no regulation and you are getting the full power of your batteries supplied directly to your atomiser.

If you don’t understand Ohm’s law, battery safety, and how to build to your mod, you probably shouldn’t be having a go until you’ve given yourself a good grounding! (If you’ll pardon the pun)

That out of the way, the Dovpo Clutch X18 is a bit of an oddity, as the batteries are arranged in parallel. This compares to the far more common series mods, where batteries can be stacked one on top of another, to double the power.

The difference is that with a parallel mod, the amount of voltage being supplied to your atomiser remains the same (so, 4.2V from freshly charged batteries). But the load in amps is spread over the two batteries, and the capacity or how long you can vape for, is doubled.

So no, you will not get double the amount of “power” with a parallel mod, but you will be able to vape for longer, and it will perform at its peak power for longer because of this.

This was sent over by Dovpo for review (thank you), as usual, I am not swayed by freebies and I shall report back honestly with what I find.

On to the review!

Design and Build Quality

The Clutch X18 comes in a choice of 6 colour ways at launch, Red, Blue, Green, Black and Gunmetal Grey.

Signature Mods Clutch X18 ColourwaysAlthough I’m sure there will be many interesting variations on these in the future, as there have been with the original clutch.

Body

The body is machined from a solid billet of aluminium, and as such it feel very rigid whilst still being quite lightweight. It’s then bead blasted and anodised, giving it a very silky premium feel.

As mentioned previously, this is a mechanical mod. As such it is really important that you know what you’re doing with it, and you have a good grasp of ohms law and the safety concepts around battery safety.Dovpo Signature Mods Clutch X18 Warning Sticker

Because of this, it’s really good to see a big battery warning information sheet as the first thing when you open the box. Even more than that, there is a sticker covering the mod which you have to remove before you can use it.

You should always use married batteries in a mod like this, ie. ones that have always been charged and discharged together.

Controls/Switches

The fire button is a lovely metal square, with some texture to the front of it. Signature Mods know that this is one area that people often like to customise, so I’m happy to say that it is fully compatible with the Clutch 21700 buttons.

It’s got a really positive throw to it, and I love how solid it feels.

Dovpo Signature Mods Clutch X18 FIre ButtonOther than the fire button, the only other control you have on the device is the little safety lock switch on the rear of the device (the other side from the one you put your batteries in).

Safety Features

This mechanical switch just rotates a little blocker, that when locked will prevent the switch from depressing and making contact.

Dovpo Signature Mods Clutch X18 Lock/Unlock

It’s a relatively simple design, but it’s been well thought out and acts exactly as you would want it to. There’s no chance of it getting moved accidentally, and it gives a lot of reassurance.

Speaking of reassurance, one of the new things from the original clutch is the introduction of a fuse in the base.

This little piece of metal is secured by 4 torx screws, and has a 37a limit. Basically if you try to push more than 37a through it the metal will break in the middle and cut the connection.

Please Note: This fuse is only designed to stop you placing the batteries the wrong way up. If you accidentally install them in series (one up, one down) it will break the fuse. If you were to place a super low resistance build in there or you get a short in your atomiser, it will not protect you.

This is a physical reverse polarity protection (something I’ve never seen before in a mech mod). It is not a safety feature to protect against an atomiser short.

Signature Tips Clutch X18 FuseThis is a great way of giving you a little extra safety. If you want, Signature Tips will be selling a solid metal bridge to remove this safety feature, but honestly I’m not sure why you would want to.

The only criticism I have of this is that although they give you a bag of 5 extra fuses, in case you are unlucky enough to blow one, they don’t provide you with a tool to unscrew them and replace them.

So bring your own screwdriver!

Base

Looking at the base of the mod, you can see all the expected regulatory marks, as well as the logos of those responsible for its creation. Signature Tips, Mike Vapes and Dovpo.

The other thing that should be obvious is the two flat headed screws. These are your battery contacts, and you screw them down to make contact with the batteries.

Dovpo Signature Mods Clutch X18 Base

I was slightly worried by this at the beginning, as once you screw them down, the batteries can be held in place quite firmly (however don’t over tighten, as you don’t want to damage your batteries!).

In the event of something going wrong, the first thing to do is always to get your batteries out the mod quickly, so I was worried this wouldn’t be easy.

However, because you can take the door of the back of the mod as well, you can push the batteries out from this side.

As a quick tip, always screw down your atomiser before inserting the batteries and screwing down the negative screws.

Doors

Speaking of the doors, you get two sets in the box. This is such a simple thing for them to have done, but it’s a really welcome touch. They attach onto the body of the mod with 6 magnets each, and once they are in place there’s absolutely no movement from them.

Signature Tips Clutch X18 DoorsThe standard doors that come on the mod allow for up to a 25mm atomiser without overhand.

However, swap these out for the thicker doors and you can now go up to a 28mm.

You’ll also notice how the rear doors have a nice big polarity indication on them. Both batteries go positive side up.

Taking the doors off the mod you can see straight through to the other side. There is a 3d printed battery self that fits inside with your contacts. If you ever need to take this out, then you just need to screw the battery screws all the way in.

Lift the positive 510 connector away from the nice and chunky PEEK insulator, and slide it out. Your switch will come out at the same time.

How Does the Dovpo Clutch X18 Perform?

I’ve had the Dovpo Clutch X18 in for review for a few weeks now, and part of the reason it has taken me a long time to getting this written review up, is that I’ve been desperately searching for things that are wrong with it!

Dovpo Signature Mods Clutch X18 Handcheck

As a reviewer, I like to be able to tell you the good and the bad of a product, so you can make an informed decision.

But honestly I’ve struggled to find anything to complain about it.

In terms of power? It’s a mech, and hits like you would expect. If there is any voltage drop then it’s pretty minimal and certainly beyond my skill to notice.

But more than that, because of the parallel configuration, it continues to provide you with that “freshly charged battery” feeling, for a lot longer than you would get were it a single battery.

The fire button is a joy, and (when there were no batteries in it!) I would find myself just absent mind-idly pressing it as I enjoyed the feeling so much.

Dovpo Signature Mods Clutch X18 Size Comparison

I don’t own a single battery Clutch, but I have borrowed one on occasion. And my only complaint there was that it didn’t feel big enough. Because the X18 is not using dual batteries, it fit into the hand so much better, and the knuckle-duster profile it very comfortable.

Although it looks like it’s quite a “square” shape at the back, the corners are all nice rounded, so it’s never uncomfortable to hold.

  • Hits like a freight train
  • Parallel batteries means vaping for longer
  • Mechanical lock works perfectly
  • Fuse for a little extra safety
  • Changeable doors depending on size of atomiser

Cons

  • No torx screwdriver to replace the fuses

Final Review Verdict

So, that was the Dovpo Clutch X18 by Signature Mods and Mike Vapes.

I use mechs now and again, but I’m not a massive mech user, partly because I get irritated that the performance starts dropping almost as soon as you start using one. As the battery discharges, you get less and less power.

Having two batteries in parallel helps to make this less apparent, as you’re now draining the power from two batteries at the same time.

So with that irritation mitigated, I find I can really enjoy using a mech. There’s something really pleasing about the simplicity of it.

The fit and finish of the Clutch X18 is really good, the anodising feels quality, and the fact it was machined out of a solid billet of aluminium means there’s no seams where things are joined.

On the whole, it’s an absolutely cracking mod and a worthy successor to the Clutch.

I started my vaping journey in 2017 with a little AIO kit. I’d made several attempts to give up smoking over the years, and I finally nailed it with vaping. I knew right away that I wanted to learn as much about all these devices as possible, and I quickly got into rebuildables and replaceable battery mods. I’ve always enjoyed kit and technology, so I’ve built up quite a collection of different tanks and mods. I love knowing how things work and what to do to get the best out of them, so sharing that knowledge and helping more people quit smoking is something I’m passionate about.
