Overview
This Relx Blade 50mg Nicotine review goes through the product listing for the RELX Blade, a disposable vape rated at up to 50,000 puffs and sold on our shop in Dubai. It is a specification-based review. We have not timed the battery, counted puffs or taste-tested every flavour for this article, so every figure below comes from the listing and is a maker claim, not a lab result.
The listing describes a 30ml pre-filled nicotine salt tank, an 850mAh rechargeable battery with Type-C fast charging, an advanced mesh coil, an LED screen for battery and e-liquid levels, Hit Boost technology and fourteen flavours. The strength is listed as 5% (50mg) nicotine salt, which is high, so this device is meant only for adult smokers who already use nicotine. In the UAE the buyer must be 21 or older, and UAE law may set a higher age limit in some settings.
Below you will find the full specification list, what each number does and does not tell you, the flavour and pack options, a pros and cons table, a comparison with other RELX models from our catalogue, delivery facts and four short FAQs. If you only want one part, use the table of contents.

Relx Blade 50mg Nicotine review: specifications at a glance
The product page lists the following for the RELX Blade. We have copied the figures as they appear and added a note where the listing is silent, because a missing figure is useful information too.
- Brand: RELX.
- Puff capacity: up to 50,000 puffs.
- E-liquid volume: 30ml pre-filled nicotine salt e-liquid.
- Battery: 850mAh rechargeable battery.
- Charging: Type-C fast charging.
- Nicotine strength: 5% (50mg) nicotine salt.
- Coil: advanced mesh coil, described as aiming for consistent flavour.
- Activation: draw-activated, with no buttons.
- Display: LED screen that tracks battery and e-liquid levels.
- Technology: Hit Boost, described as giving a stronger flavour and vapour. The listing does not explain how it works.
- Design: sleek, compact and ergonomic. Dimensions and weight are not stated.
The listing gives the strength in two ways, 5% and 50mg, and both agree with the 50mg in the product name. That consistency is welcome, because many disposable listings contradict themselves. It does not tell you how strong the device feels to use, only how much nicotine the liquid contains by the maker’s own figure.
The listing does not give a certificate number, a UAE.S 5030:2018 test reference or an ECAS registration. We do not repeat any claim of approval here, because the listing gives nothing to check it against. UAE.S 5030:2018 is the national technical standard for vaping devices and e-liquids, and ECAS is the conformity assessment scheme linked to it, so those are the terms to ask about if you want proof for a specific batch.
What the 50,000-puff rating and 30ml tank mean
A puff rating is a number the maker works out under its own conditions. Real use varies with how long each draw lasts, how often you vape and how warm the device gets. Two people can use the same device and reach very different totals, so treat 50,000 as a ceiling that describes the design intent, not a promise for your own habits. Note the wording too: the listing says up to 50,000 puffs, which is a maximum.
The more concrete figure is the 30ml of nicotine salt e-liquid. Volume is something you can compare directly between listings. In our catalogue the RELX Optimus 60000 lists about 30mL, the RELX Ace lists 22mL and the RELX Creator lists 20ml, so the Blade sits at the larger end of the RELX range on paper, with the same tank size as the Optimus despite a lower puff rating.
Nicotine salt is worth a short explanation. It is a form of nicotine that is generally described as smoother at higher strengths than freebase nicotine, which is why salt liquids are common in 50mg disposables. Smoother does not mean milder. The strength is still 5%, and a 30ml tank at that strength holds a large total amount of nicotine.
That is another reason this model is aimed at adults who already smoke or vape every day and not at occasional users. If you vape rarely, a lower-strength device is a more sensible match, and our disposable vape buying guide explains how to match puff rating, strength and daily use.
Finally, the listing does not publish an ingredient list or a PG/VG ratio. If either matters to you, for example because of an allergy, ask the shop before buying instead of assuming.
Battery, charging, screen and Hit Boost
The battery is the clearest spec on the page: 850mAh, rechargeable, with Type-C fast charging. A stated mAh figure is helpful because you can compare it with other listings. The RELX Optimus also lists 850mAh, while the RELX Creator lists 800mAh. What the figure cannot tell you is runtime, because that depends on the coil, the power output and how you draw. This review makes no claim about how long a charge lasts.
Type-C charging uses the same cable as most current phones and laptops, so you are unlikely to need a special lead. The listing says charging is fast but gives no charging time, so we cannot put a number on it.
The LED screen is the other practical feature. The listing says it tracks battery and e-liquid levels. For a device with a 30ml tank this is useful, because you can see when the liquid or the charge is running low. The screen size and layout are not described, so we are not going to describe them either.
The device is draw-activated. In plain terms, you inhale and it fires. There is no refilling and no coil to change, which is the point of a disposable format. When the device is finished it should be disposed of properly through electronic waste collection and not thrown in household rubbish, because it contains a lithium battery.
Two phrases in the listing are marketing terms. The mesh coil is described as advanced and aimed at consistent flavour, and Hit Boost is described as giving stronger flavour and vapour. The listing does not give the coil resistance, the power output or any detail on how Hit Boost is triggered, so we would not read anything technical into either phrase.
Flavours and pack options
The listing names fourteen flavours, covering fruit, menthol, dessert, coffee and tobacco styles. The descriptions below paraphrase the short notes in the listing. They are the maker’s flavour descriptions, not our tasting notes.
- Cola Ice: cola soda with icy menthol.
- Watermelon Raspberry: juicy watermelon with ripe raspberry.
- Kiwi Passion Guava: a tropical blend of kiwi, passion fruit and guava.
- Strawberry Mango: sweet strawberry with juicy mango.
- Lemon Mint: zesty lemon with fresh mint.
- Peach Mango Watermelon: a tropical fruit medley.
- Cappuccino: a coffee flavour inspired by creamy cappuccino.
- Mix Berry: blueberry, raspberry and strawberry.
- Watermelon Ice: watermelon with icy menthol.
- Pistachio Ice Cream: sweet pistachio with ice cream notes.
- Strawberry Kiwi: sweet strawberry with tangy kiwi.
- Strawberry Watermelon: a fruit fusion.
- Creamy Tobacco: a smooth tobacco flavour with creamy undertones.
- Grape Ice: purple grape with icy menthol.
A small inconsistency is worth knowing about. The description spells one flavour as Watermelon Raspberry, while the selector on the product page shows it as Watermelon Rusberry. They are most likely the same flavour, and the shop can confirm. Flavour availability changes, so choose from the live selector and not from this article.
The pack options are 1 PC and a box of 10 PCS. The single device is the right choice if you are trying the model for the first time. The box suits a household or a business that wants a mix on hand, but at 5% strength it is a lot of nicotine to store, so keep it locked away from children and pets. To see every model from the maker, visit the RELX brand page.
Pros and cons
The table below is drawn from the listing alone. Positives are things the listing states. Negatives are gaps or cautions we can see in the same listing. Nothing here comes from hands-on use.
| Pros | Cons |
|---|---|
| Rated at up to 50,000 puffs | The puff rating is a maker claim and depends on how you vape |
| 30ml pre-filled nicotine salt e-liquid | Dimensions and weight are not stated |
| 850mAh rechargeable battery with Type-C fast charging | 5% (50mg) nicotine is high and unsuitable for non-smokers |
| LED screen for battery and e-liquid levels | No certificate number, UAE.S 5030:2018 reference or ECAS detail on the listing |
| Fourteen flavours, sold as 1 PC or a box of 10 PCS | Hit Boost and the mesh coil are described only in marketing terms |
| Strength stated consistently as 5% and 50mg | One flavour name differs between the description and the selector |
How it compares with other RELX models
To keep the comparison fair, every row below was checked against the live product listing on 15 October 2026. We chose three other RELX disposables from our catalogue that cover a higher rating, a mid rating and a smaller starter-style model. Where a listing leaves a figure out, the table says so.
| Model | Puff rating | E-liquid | Battery | Nicotine | Price |
|---|---|---|---|---|---|
| RELX Blade | Up to 50,000 | 30ml | 850mAh | 5% (50mg) | AED 49 |
| RELX Optimus 60000 | Up to 60,000 | 30mL approx. | 850mAh | 5% (50mg) | AED 55 |
| RELX Peace 25K | Up to 25,000 | Not listed | High-capacity rechargeable, mAh not listed | 20mg (2%) | AED 45 |
| RELX Creator Starter Kit | Up to 15,000 | 20ml | 800mAh | 30mg (3%) | AED 55 |
Reading across the rows, the Blade and the Optimus share the same tank size, battery and strength, and the Optimus adds 10,000 rated puffs for AED 6 more. The Peace 25K and the Creator both list lower nicotine strengths, so they are the rows to look at if 5% is more than you want. You can read our separate RELX Optimus 60000 review, RELX Peace 25K review and RELX Creator review for each model in more detail.
The table can only show which listing promises more on paper. Without tested output, runtime and flavour data, a higher rating is not proof of a better device. For a wider view of the very high puff-count devices we stock, see the 50,000 puffs disposable vape range.
Who it suits, price and stock
Who it may suit. Adult smokers, aged 21 or over, who already use 5% nicotine, want a large-capacity device and like a wide flavour choice, including a tobacco and a coffee option.
Who should skip it. Anyone who does not smoke, anyone under 21, anyone who wants a low nicotine strength and anyone who needs a small pocket device. Skip it too if you need a published ingredient list or certificate before buying, because the listing has neither.
Price and stock. When we checked on 15 October 2026 the variable product showed a price from AED 49 and was in stock. Prices and stock change, so use the RELX Blade 50000 puffs 50mg nicotine product page as the source of truth. Our disposable vape category shows the rest of the range if you want to compare before you decide.
One practical point: a single device at AED 49 is below the AED 100 minimum order, so you will need to add another item or choose the box of 10 PCS to check out. The delivery section below explains the fees.
UAE rules, age limit and delivery
Vaping products in the UAE are regulated, and the technical standard for devices and e-liquids is UAE.S 5030:2018, with ECAS as the conformity scheme. You can read the official position on the Ministry of Industry and Advanced Technology (MoIAT) website. The rules can change, so check the current notice before you buy and never assume a product meets them just because it is on sale.
This is an adults-only product. You must be 21 or older to buy it, and UAE law may set a higher age limit in some settings. Our age verification and responsible use page explains the checks we apply. Nicotine is addictive, and this is not a product for non-smokers, pregnant women or people with heart conditions.
Delivery in short. The full details are on our vape delivery Dubai page and our delivery and payment page. The key facts are below.
- Delivery is free above AED 350. An order of exactly AED 350 pays AED 30, and orders below that also pay a flat AED 30.
- The minimum order is AED 100.
- Dubai, Sharjah and Ajman: about 2 hours, from 10am to 11pm, 7 days a week. Pay by cash, card or bank transfer.
- Other emirates: courier within 24 hours, Monday to Saturday. Pay by cash on delivery or bank transfer.
