A 1ml all-in-one is a sealed, rechargeable pen with a tank of up to 1ml, a built-in battery and a ceramic heating core, supplied empty for licensed fillers. Six CCELL models in our range fit that brief: Blanc, DS01 Series, Skye II, Listo, Slym and Eco Star. Blanc has a zirconia ceramic post, DS01 comes in two builds, Skye II has a stainless steel housing, Listo holds 1.0ml on a 350mAh battery, Slym is 6.7mm deep and Eco Star has a biodegradable PLA body. These all-in-ones are available to approved trade (VIP) accounts. Below we narrow the choice using each listing’s published specification.
Key takeaways
- Listo is the only model locked to a single 1.0ml size; the other five offer smaller tanks as well.
- Four models charge by micro-USB (Blanc, Skye II, Listo, DS01 -UB) and two by USB-C (Slym, Eco Star).
- Four models name a heating generation: Blanc (EVO), Slym (EVO), Eco Star (EVOMAX) and DS01 (SE). Skye II and Listo use CCELL ceramic heating elements with no generation named.
- All six are available to approved trade (VIP) accounts, so contact us to apply for access.
The six devices side by side
The three tables below cover tank, battery and size, then body and charging, so each stays easy to scan.
| Listing | Tank options | Battery |
|---|---|---|
| Blanc | 0.3ml / 0.5ml / 1ml | 190mAh |
| DS01 Series | 0.3ml / 0.5ml / 1ml | 135 to 330mAh by version |
| Skye II | 0.5ml / 1.0ml | 190mAh |
| Listo | 1.0ml | 350mAh |
| Slym | 0.3ml / 0.5ml / 1.0ml in the spec; 0.5ml / 1.0ml in the shop | 280mAh / 210mAh / 280mAh |
| Eco Star | 0.5ml / 1ml | 180mAh |
| Listing | Dimensions | Body |
|---|---|---|
| Blanc | φ10.6 x 108.4 / 117.4 / 125.23 mm | Metal body, glass oil tank |
| DS01 Series | φ10.5 to 10.6 x 93.3 to 116.7H mm | Stainless steel, visible glass tank |
| Skye II | φ11.0 x 104H mm | Stainless steel housing, visible oil tank |
| Listo | 97.8H x 22.3W x 10.8D mm | Compact visible oil tank design |
| Slym | 99H x 19W x 6.7D mm (0.3ml and 0.5ml) | Full metal housing |
| Eco Star | 89H x 22.1W x 16.6D mm | Biodegradable PLA, corn stover based |
| Listing | Charging | Heating core on the listing |
|---|---|---|
| Blanc | Micro-USB | EVO |
| DS01 Series | Micro-USB on the -UB build | SE ceramic |
| Skye II | Micro-USB | CCELL ceramic element |
| Listo | Micro-USB | CCELL patented ceramic core |
| Slym | USB-C | CCELL EVO |
| Eco Star | USB-C | EVOMAX |
All six are inhale activated. A micro-USB port will not accept a USB-C cable, so a range that standardises on one cable should filter on charging first.
Heating cores and what they mean for oil choice
Core type is usually the first filter for a product team, because it decides which oils a device suits. SE is CCELL’s standard ceramic core, introduced in 2016, and suits pourable oils. EVO followed in 2022 for terpene-rich oils, and EVOMAX in 2023 for all oil types.
- Blanc: EVO heating, specified for high terpene extracts.
- Slym: a CCELL EVO core. CCELL reports 25% higher thermal efficiency than its first-generation core and up to 50% more vapour with live resin, which are manufacturer claims.
- Eco Star: an EVOMAX core, listed as compatible with all types of oils.
- Skye II: a CCELL ceramic heating element, with no generation named by CCELL.
DS01 uses CCELL’s SE ceramic element, and Listo uses a CCELL patented ceramic heating core with no EVO or EVOMAX generation named. Trial thicker oils before committing. Our comparison of EVOMAX and SE ceramic cores explains the trade-offs, and our blog on oil viscosity and intake aperture shows how thickness affects a fill. For temperature background, read terpenes and hardware temperature.
CCELL Blanc: ceramic post and mouthpiece in a metal body
Blanc is built around a zirconia ceramic post and aluminium ceramic mouthpiece, so ceramic sits at the points that touch the oil. A glass oil tank sits inside a metal body. Tank options are 0.3ml, 0.5ml and 1ml, with heights of 108.4mm, 117.4mm and 125.23mm on a 10.6mm diameter.
Two feature panel details matter for production. The snap-fit mouthpiece needs 60% less capping force, which the panel links to easier batch capping. The 190mAh micro-USB battery is described as rechargeable up to 10 times. The shop colour is Silver.
CCELL DS01 Series: two builds under one name
The CCELL DS01 Series is a pen-style device in three tank sizes. The spec list splits by build, and the -UB line adds a micro-USB port.
| Feature | Standard DS01 | DS01 -UB |
|---|---|---|
| Mouthpiece | Screw-on, food-grade | Snap-fit, food-grade |
| Centre post | Low-lead brass | Medical-grade stainless steel |
| Charging | Not listed | Micro-USB |
The -UB line is also smaller, and its snap-fit mouthpiece makes capping straightforward. Shop colours are Black and Silver. Because DS01 covers two builds, always state -UB or standard on the order. If material specification matters to your compliance file, request written confirmation for the exact variant before ordering.
CCELL Skye II: ceramic core in a stainless steel pen
The CCELL Skye II all-in-one is the follow-on to Skye I, formerly TH001. It offers 0.5ml or 1.0ml, a 190mAh battery and a φ11.0 x 104mm size. The listing names a CCELL ceramic heating element, a PA mouthpiece, a medical-grade stainless steel post and a stainless steel housing.

Both volumes share the listed 104mm height, which simplifies packaging for a two-size range. The shop colour is Silver, and the battery charges by micro-USB.
CCELL Listo: 1.0ml and a 350mAh battery
Listo is a single 1.0ml device with a 350mAh battery, which compares with 190mAh for Blanc and Skye II and 180mAh for Eco Star. It measures 97.8H x 22.3W x 10.8D mm and lists a compact visible oil tank, a food-grade PCTG mouthpiece, 316L stainless steel internals, a built-in LED indicator and micro-USB charging.

Listo comes in seven shop colours: Black, Blue, Orange, Purple, Red, White and Yellow. That makes it practical when each product in a range needs its own colour. Its heating is a CCELL patented ceramic core.
CCELL Slym: 6.7mm deep with EVO heating
The CCELL Slym ultra-slim all-in-one lists a full metal housing at 99H x 19W x 6.7D mm for the 0.3ml and 0.5ml sizes. Inside is a CCELL EVO heating core around a 316L stainless steel post, and it charges by USB-C.

The shop variation options are 0.5ml and 1.0ml, in Black, Gold and White, and the listing is open to customisation. The spec list prints dimensions for the 0.3ml and 0.5ml sizes only, so confirm the 1.0ml dimensions with us before you design an insert.
CCELL Eco Star: PLA body and a removable battery
Eco Star has a biodegradable PLA housing and a removable battery. It comes in 0.5ml or 1ml with a 180mAh battery, at 89H x 22.1W x 16.6D mm. The PLA is corn stover based, and the battery can be removed from the housing for separate recycling.

Airflow runs through two clog-free vents, with an airway isolated from the electronics. The snap-fit mouthpiece is batch-capped 25 pieces at a time. Shop colours are Black and Cream.
Environmental wording
If you mention the PLA housing or removable battery in marketing, keep to the wording on the spec sheet and check any environmental claim with your own advisers. For a starting point on regulatory conversations, read our UK and EU hardware compliance overview and our Tobacco and Vapes Act hardware supplier checklist.
Tank size, battery size and rechargeability
Battery capacity scales with tank size on several of these listings, so the right question is how long the battery lasts against the oil it carries. DS01 uses smaller cells in its 0.3ml and 0.5ml versions, and Slym lists 280mAh, 210mAh and 280mAh by tank size. Listo and Eco Star hold a single battery figure for each model.
Rechargeability matters for a different reason. The DS01 feature panel says the micro-USB -UB line prolongs shelf life and removes the worry of a drained battery with unfinished oil. Blanc’s panel gives a figure of up to 10 recharges. A device without a charging port can leave oil unused, which is why we flag the port type in every comparison.
When a 0.3ml tank makes sense
A small format keeps unit costs low and lets a brand offer a trial size without giving away a full unit. It also suits retail or regulatory contexts where a smaller quantity is preferred. Only Blanc and DS01 list 0.3ml as a shop option on the product page, so check the live variation list before you plan around it.
Testing the six side by side
Because the six differ in post material, core and charging port, a side-by-side round should hold everything else constant.
- Use the same oil and fill volume in each device, choosing the 1ml or 1.0ml size where the device offers it.
- Cap each device with the method its mouthpiece suits: snap-fit press for Blanc, DS01 -UB, Slym and Eco Star; screw-on for standard DS01.
- Leave the test units upright for the rest period your quality process sets, then inspect.
- Draw through the whole tank, including the last draws when the oil level is low and flow changes.
- Test recharge on each and note the port type.
- Record results with the model and build name so the chosen device can be reordered exactly.
Choosing a 1ml all-in-one
This table matches a brief to the model to test first.
| Your brief | Start with | Why |
|---|---|---|
| Ceramic post and mouthpiece, 0.3ml option | Blanc | Zirconia post, EVO core |
| Brass or stainless post under one model name | DS01 Series | Standard and -UB builds |
| Stainless housing, one height for both volumes | Skye II | 104mm for 0.5ml and 1.0ml |
| Single 1.0ml size, seven colours | Listo | 350mAh battery |
| Thinnest body with USB-C | Slym | 6.7mm deep, EVO core |
| Plant-based housing, all oils | Eco Star | PLA body, EVOMAX core |
Battery figures run from 135mAh, the low end of the DS01 range, up to Listo’s 350mAh. If your range standardises on one charging cable, filter on the port first: micro-USB for Blanc, Skye II, Listo and DS01 -UB, and USB-C for Slym and Eco Star.
Branding and ordering
All six list customisation or a laser engraving add-on on their product pages. Our engraving page sets out the artwork we need and how proofs are approved, and laser engraving is a UK service.
Fix these lines on every order:
- Model, and for DS01 the build (standard or -UB).
- Tank size from the shop options.
- Colour as listed.
- Artwork for customisation, if used.
These all-in-ones are available to approved trade (VIP) accounts. Our guide to CCELL wholesale in the UK explains MOQ, trade pricing and how to order, and free shipping applies over £80, to be confirmed at checkout. Hardware leaves our Bolton premises empty, for licensed UK businesses that fill and sell under their own approvals.

FAQ
Which of these devices has a ceramic centre post?
Blanc is the one with a ceramic centre post, listed as zirconia ceramic, alongside a snap-fit aluminium ceramic mouthpiece and a glass oil tank. The others use stainless steel posts, apart from the standard DS01 build, which lists a low-lead brass post. Ask us for written material confirmation if your compliance file needs it.
Which offer a 0.3ml tank?
Blanc and DS01 Series both list 0.3ml, 0.5ml and 1ml tank options. Slym also prints 0.3ml in its spec list, although its shop variation options show only 0.5ml and 1.0ml. Skye II, Listo and Eco Star do not offer 0.3ml. Confirm the size with our team before ordering a smaller tank.
Which use USB-C?
Slym and Eco Star charge by USB-C. Blanc, Skye II, Listo and the DS01 -UB build charge by micro-USB, and a USB-C cable will not fit a micro-USB port. If you want one cable across your range, choose from the USB-C pair or standardise on micro-USB for the other four.
What does -UB mean on DS01?
The -UB marks the DS01 build that swaps in a snap-fit mouthpiece, a medical-grade stainless steel post and a micro-USB port. It is also smaller than the standard build. The standard DS01 uses a screw-on mouthpiece and a low-lead brass post, so state which build you want on every purchase order.
Does Eco Star support batch capping?
Yes. Eco Star’s snap-fit mouthpiece is batch-capped 25 pieces at a time, which tightens the seal and shortens capping time on a filling line. Blanc’s snap-fit mouthpiece also needs 60% less capping force. Test capping on your own equipment, since results depend on your tooling and oil.
Can anyone buy these 1ml all-in-ones?
No. These all-in-ones are available to approved trade (VIP) accounts rather than as open public stock. Licensed UK brands and filling businesses can contact our team to apply, and trade terms are explained in our wholesale ordering guide. The buyer remains responsible for its own licences, testing and labelling.
