  • Description

    The Guardian 40W mod is small and light, weighing just 109 grams and less than 6 cm in length, but still provides up to 40 watts of power - meaning, when combined with the included low resistance mesh coils, it can provide superb vapour.

    This compact device comes with a 0.49 inch OLED screen which supplies key data such as resistance levels, puff count, power levels and more. The device can be fully controlled by a sensitive ergonomic power button. An upgraded air-flow system is controlled by a bottom air-ring with 5 inlet holes, each with different sizes, to allow you choose between a restricted and a more airy vape.

    The Smok Guardian 40W comes with a USB-C charging port and can reach full charge in just 90 minutes.

    The included TF RPM Tank comes with a sealed gasket, redesigned air system and a secure locking mechanism which all help to eliminate leaking and flooding. The mesh and triple mesh RPM coils produce a thick vapour and a concentrated flavour and contribute to a fast ramp-up time. Depending on the coil used, this device can be used for either a Mouth-to-Lung or a restricted Direct-Lung inhale.

    Who is the Smok Guardian 40W Kit for?

    This kit is ideal for vapers who prefer a compact device which is still capable of producing dense vapour and concentrated flavour.


    The Guardian 40W mod will work with most tanks with a 510 connection.

    The TF RPM Tank works with Smok RPM series coils except for RPM2 and RPM160 coils. The replaceable 510 drip can be removed and replaced with any other drip tip with a 510 connection. It will work with most mods with a 510 connection.


    What e-liquid can I use with the Smok Guardian 40W?

    The lower resistance 0.4 Ω coil is best used with e-liquids with a higher VG:PG ratio, such as 70:30. The 0.6 Ω coil works well with e-liquids with a VG:PG ratio of 50:50 or 60:40.

    How long does the Smok Guardian 40W battery last?

    Do note that battery life depends on usage and a heavy user will need to recharge more frequently than a light user. Batteries will also last longer between charges when used at lower wattages. That said, the internal 1600 mAh battery combined with the 1 - 40 watt power levels means this device will provide most users with a day of usage before needing recharging.

    What is the difference between OLED and LED screens?

    OLED screens are brighter, lighter and thinner than LED screens, and produce a higher quality image.

    Can I charge my Smok Guardian 40W overnight?

    Lithium batteries should not be left unattended when charging. For more information see our battery safety infographic.

You Must Be Over 18 to Buy From E-cigarette Direct

Why do I have to prove my age?

To our website you look under 18.

So, as a responsible retailer, we need to check your age.

You'll only need to do this once and it takes less than a minute.

Our age verification system is quick and easy to complete. Simply enter your date of birth, and our system will use the information from your order to do the rest.

On rare occasions, you might find that you don’t succeed on first try. Don’t worry - our super-friendly customer service team is on hand to ensure that, as long as you are 18 or over, you can still get your vaping supplies!

Once you have confirmed your age we won’t usually need to check again. (Exceptions can occur, for example if you change your name).

(You can help us check your age by ensuring your name and address are spelt absolutely correctly in the order form :) )

How your data is used

We use as little data as possible. The only data that ECigaretteDirect keep is information needed to send your order, and your date of birth (so we only have to check once!)

Your age is checked using Experian, which will check the information you provide against information in existing records to confirm you are over 18. No credit check is performed but a record of the search will be visible to you on your credit report. This will not affect your ability to get credit.

Why do we check age?

As you may know, there has been some concern that under-18’s may try vaping.

This is against both our company policy and the law.

And as responsible retailers, we need to do everything we can to ensure that every customer is of legal age.

For more information, see our Terms and Conditions.

How Secure is e-Cigarette Direct?

Your privacy is important to us, and your personal information should remain just that - personal.

See the little green lock in the search bar? That’s our security certificate (SSL or secure socket layer to be precise). It encrypts all the information you enter so that no-one else can see it.

Information you provide for age verification is sent securely to Experian and no details of the checks are stored in our system. Ever.

If you have any concerns, please call our friendly customer services team on 01792 852843 (Mon - Fri, 9am - 5pm).

For the techies: Our SSL certificate uses an sha256 hashing algorithm.
