CCELL Sleek All-in-One: Specs, Filling and Who It Suits

The CCELL Sleek is an ultra-thin, fillable all-in-one built on the CCELL 3.0 heating core. It has a precision-machined metal body, a smart display screen, two voltage settings (L 3.0V and H 3.2V), a 210mAh battery and Type-C charging, and it comes in a 1ml or 2ml tank in Gold, Aurora or Blue. It is inhale activated and supplied empty for licensed filling. This guide covers the real specifications, how filling works for a closed all-in-one, how the Sleek compares with the other CCELL 3.0 all-in-ones we supply, and which brands it suits.

Key takeaways

• The Sleek is a sealed all-in-one: battery, tank and CCELL 3.0 heating core are one unit, with no 510 thread and no separate battery.
• Two sizes share one body width: the 1ml is 8.8mm deep and the 2ml is 9.9mm deep, both 41.1mm wide.
• A two-position toggle switch on the bottom selects L 3.0V or H 3.2V, next to the Type-C port.
• It is supplied empty, so filling belongs with a licensed brand’s filling line, not with the end user.
• For another 3.0 format, such as a longer bar, a dual tank or a three-voltage model, compare it with the rest of the CCELL 3.0 all-in-ones range.

What is the CCELL Sleek?

The CCELL Sleek is a slim, flat all-in-one from CCELL’s 3.0 platform. In CCELL’s launch material it is described by its thin profile and a precision-machined metal body, and the headline is that the 1ml version is only 8.8mm deep. That puts it closer to a card-shaped device than to the round pens and long bars most buyers know from the 510 range.

An all-in-one is a closed system. The battery, the oil tank and the heating core are built together, so there is no thread to screw a cartridge onto and no battery to swap. If you are still deciding between formats, our guide to 510, pod and all-in-one hardware explains the differences in plain terms. The short version is that an all-in-one trades flexibility for a clean, finished product that goes straight from the filling line to the customer.

The Sleek is sold empty. CCELL does not produce or sell oil, and the hardware is intended for licensed brands that fill it. 3DevicesCCELL supplies authentic CCELL hardware to UK trade buyers, and the Sleek is listed as part of the 3.0 all-in-one range.

CCELL Sleek specifications

The figures below come from the CCELL Sleek launch file supplied to 3DevicesCCELL and match the specification on the product page. We list only what the launch file states.

The launch file does not give a draw resistance, a charge time or a puff count, so we do not quote any. If a figure matters for your packaging or your insert, ask the trade team to confirm it in writing before you print anything.

Smart screen, voltage switch and Type-C charging

Two modes on a toggle switch

A simple slide of the two-position toggle switch at the bottom of the device changes the mode. L is 3.0V and H is 3.2V. The switch sits beside the Type-C port, so there is no menu and no button sequence to teach your customers. For a brand, that means one line of instruction on the insert: slide to L for the lower setting, slide to H for the higher one.

The difference between the two settings is only 0.2V, so the effect depends on the oil. Thicker, more viscous oils generally benefit from a little more heat and thinner, terpene-rich oils from a little less, which is the same logic we explain in our guide to voltage settings for distillate, live resin and rosin. Test both positions with your own oil before you decide which one to recommend on pack.

The smart display screen

The Sleek has a smart display screen intended to keep the user informed at a glance. In CCELL’s product images it shows the remaining power as a number and the selected L or H setting. We recommend checking a sample for the exact display behaviour before you write instructions or plan packaging, because the launch file shows images rather than a written description of every screen state.

Inhale activation and Type-C charging

The Sleek is inhale activated, so there is no fire button: a gentle draw on the mouthpiece starts it. The 210mAh battery is built in and charges over Type-C, which is the connector most customers already have a cable for. Because the battery cannot be removed, a customer who runs out of charge simply plugs the device in. Our general guide to how to use a CCELL all-in-one covers first draw, charging habits and fixes that apply to the whole all-in-one family, and it is a useful starting point for your own insert wording.

The CCELL 3.0 heating core inside the Sleek

The Sleek uses the CCELL 3.0 heating core. CCELL’s launch file credits it with two named technologies. The first is a 3D Stomata ceramic, described as an interconnected heating channel structure that creates a “molecular highway” for predictable oil penetration, intended to help prevent clogging and leakage. The second is Nexus Film, a mesh-interlock heating layer that CCELL says reduces peak atomisation temperature by 30 percent and heats evenly, so that terpenes and flavour are preserved.

These are CCELL’s claims, taken from CCELL’s own launch file, and they are not independent test results. They are still useful to a buyer, because they explain why the 3.0 platform is positioned for flavour-focused and heat-sensitive oils. For the wider picture, read our pages on heating technology and the CCELL 3.0 platform, and the news piece on CCELL 3.0 heating for live extracts.

Filling the CCELL Sleek

The Sleek is supplied empty, and it is a closed system, so filling is a production step rather than a customer task. CCELL describes its all-in-ones as designed for automated filling, which is how they are meant to be filled at volume. The launch file does not publish a filling method, a fill line or a filling fixture for the Sleek specifically, so we do not describe one.

What a brand can plan for today:

• Choose the tank first. Decide on 1ml or 2ml before you buy hardware, because the pack, the label and the fill volume all follow from it.
• Fill on proper equipment. A brand that fills at volume uses a filling machine, and 3DevicesCCELL supplies a semi-automatic filling and capping machine for CCELL hardware. Its page names fixtures for TH2 cartridges and all-in-ones such as the Easy Bar. Ask the team whether a fixture is available for the Sleek before you assume one is, and confirm it in your quote.
• Test a small batch. Fill a handful of units with your oil, leave them upright for a day and check for leaks and for flooding at the mouthpiece before you commit to a run. Our guide to filling ceramic cartridges without leaks covers the general filling habits for CCELL hardware, and is worth reading alongside your own filling procedure.
• Keep it upright in storage. A filled unit lying on its side is a common cause of flooding, in any all-in-one.

Hand filling an all-in-one is not what the product is designed for. If you are weighing up a machine against filling by hand for your volumes, our separate guide to the filling and capping machine sets out when each makes sense.

Branding and OEM options

CCELL lists the following manufacturing options for the Sleek, and they are worth reading before you plan artwork:

• The mouthpiece is injection moulded.
• The oil tank is injection moulded with spray coating.
• The battery case is injection moulded with spray coating.
• The highlighted front area of the battery case can take silkscreen printing, colour printing or laser engraving.

The launch file marks a defined front area for printing and engraving on both the 1ml and 2ml bodies, which is where your logo and any compliance marks would go. Minimum quantities and artwork formats are agreed with the trade team. For the background on engraving and private label, read our guide to laser engraving and private-label hardware. Labelling requirements for the finished product are a separate topic, covered in our UK guide to cartridge and packaging labels.

CCELL Sleek compared with the other CCELL 3.0 all-in-ones

The Sleek is one of several all-in-ones on the 3.0 platform that we supply. They share the CCELL 3.0 heating core family, but they differ in shape, battery and controls. This table summarises the range using the specifications on each product page.

Three comparisons come up most often:

• Sleek or AirOne. Both are flat, both are 210mAh with Type-C and both offer 3.0V and 3.2V on a bottom switch. The Sleek adds the smart display and a metal body, while the AirOne has an indicator light and a wider choice of six colours.
• Sleek or GemBox. The GemBox is a box format with a postless prism-cut tank, and its smart display model adds preheat and a third voltage at 3.4V. The Sleek is thinner and simpler, with two settings and no preheat listed.
• Sleek or GemBar. The GemBar is a long, narrow bar with a larger 265mAh battery and a faceted tank. The Sleek is wider and flatter and carries a display, which suits a different kind of pack.

Our longer guide to the CCELL 3.0 all-in-one range goes into the older models in more depth, and our guide to 1ml all-in-one hardware covers other 1ml all-in-ones if you want to compare against models on different heating cores.

Who the CCELL Sleek suits

The Sleek is a good fit for:

• Brands that want a slim, premium-feeling all-in-one on the 3.0 platform, where the metal body and the display carry the shelf appeal.
• Fillers who want a choice of 1ml or 2ml in the same body width, so one pack design can serve both sizes.
• Retailers who want three clear colours: Gold, Aurora (a blue to pink-purple gradient) and Blue. Send us your colour split when you enquire.
• Brands that want a simple customer instruction: draw to use, slide the switch to change setting, plug in over Type-C to charge.

It is not the best fit if you need a removable battery, a 510 thread so that customers can swap cartridges, or a dual-tank format. For those, look at the 510 batteries and cartridges, or at the MixJoy. It is also worth being honest about what the launch file does not give us: there is no preheat on the Sleek, no third voltage and no published charge time, so a brand that needs any of those should compare it against the GemBox smart display model.

Ordering the CCELL Sleek: trade pricing, minimums and UK delivery

Pricing for the Sleek is trade pricing, ex VAT, and it varies by tank size. We do not publish figures in this guide, because they are tiered and are confirmed with each enquiry. Ask the trade team for current pricing on the 1ml and the 2ml, and tell them the colour split and quantity you have in mind. Our guide to CCELL wholesale in the UK, minimum orders and trade pricing explains how orders work in general.

UK delivery is available, and the stock status shown on the product page is the current position. If the Sleek is showing as out of stock, contact the team through the contact page, because availability can change between restocks and the team can confirm timing.

Is the CCELL Sleek authentic, and what about UK rules?

3DevicesCCELL supplies authentic CCELL hardware as an authorised UK distributor, and the Sleek is no exception. If you want to know how to check a unit from any supplier, our guide to how to spot fake CCELL hardware lists the checks.

CCELL states that these products are intended for CBD use only and are not to be used by minors, and the hardware is sold empty. Whether a particular device and fill meets UK product rules is a question for your own legal adviser, as is the position of any all-in-one under the UK single-use vapes ban. Our hardware supplier checklist for the Tobacco and Vapes Act is a useful starting point for the questions to ask.

FAQ

What is the CCELL Sleek?

The CCELL Sleek is an ultra-thin, fillable all-in-one on the CCELL 3.0 platform. It has a 1ml or 2ml BPA-free PA tank, a built-in 210mAh battery, a smart display screen, two voltage settings and Type-C charging, in Gold, Aurora or Blue. It is supplied empty for licensed filling.

What sizes and colours does the CCELL Sleek come in?

The tank is 1ml or 2ml. The 1ml measures 69H x 41.1W x 8.8D mm and the 2ml measures 72.9H x 41.1W x 9.9D mm. The colours are Gold, Aurora and Blue. Confirm the tank size and colour split in writing when you order.

How do the two voltage settings work?

A two-position toggle switch on the bottom of the device, beside the Type-C port, selects L at 3.0V or H at 3.2V. You can change between them at any time without a menu. Test both with your own oil before you recommend one to customers.

Does the CCELL Sleek need a separate battery or a 510 thread?

No. The 210mAh battery is built in and charges over Type-C. The Sleek has no 510 thread, so it does not work with 510 batteries or cartridges, and it is not a replacement for them.

How is the CCELL Sleek filled?

It is supplied empty and is a closed system, so it is filled by the brand during production. CCELL designs its all-in-ones for automated filling. The launch file gives no filling method for the Sleek, so ask the trade team about a suitable fixture or process before you plan a filling line.

Can the CCELL Sleek be branded or engraved?

CCELL lists silkscreen printing, colour printing and laser engraving on the highlighted front area of the battery case, with spray coating on the case and tank. Ask the trade team about minimum quantities and artwork formats.

How much does the CCELL Sleek cost wholesale in the UK?

Trade pricing is quoted ex VAT and varies by tank size, so we do not publish a figure here. Ask the trade team for current pricing, and check the product page for stock status. UK delivery is available.
