Marsilen currently states about 7 days after dispatch for its listed warehouse routes, a 14-day change-of-mind period for eligible unopened products and a 48-hour reporting window for damaged, defective or incorrect deliveries. VapeSourcing uses different regional storefronts, so its shipping and warranty terms can change with the market and product type.

One Brand vs a Multi-Brand Store
| What you are comparing | Marsilen | VapeSourcing |
|---|---|---|
| Store type | Mainly Marsilen-branded products | Multi-brand retailer |
| Product choice | Smaller, focused range | Much broader range of manufacturers and device types |
| Product information | Product and brand information stay in one system | Specifications differ from brand to brand |
| Shipping | Depends on stock, destination and Marsilen warehouse route | Depends on regional storefront, warehouse and carrier |
| After-sales | Handled through Marsilen | Rules vary by product type and regional store |
VapeSourcing’s UK catalog currently includes brands such as Vaporesso, VOOPOO, SMOK, OXVA, Uwell, Geekvape, Aspire and Lost Vape. That is useful if you want to put several brands side by side.
Marsilen is narrower. Its current product range is built around a few quite different formats rather than hundreds of unrelated models.
That smaller range does not mean the devices are similar. They are not.
Marsilen Product Specs Side by Side

| Specification | Deimos | NOVA 4in1 | NOVA 3in1 | PRO 30K |
|---|---|---|---|---|
| Positioning | Higher-output DTL / MTL dual-mode device | 4 flavors in one device | 3 flavors in one device | Compact refillable device |
| Published puff rating | Up to 200,000 | Up to 80,000 | Up to 60,000 | Up to about 30,000 across 3 fills |
| E-liquid | 60 mL | 4 × 10 mL, 40 mL total | 3 × 5 mL, 15 mL total | 10 mL refillable pod |
| Battery | 1200 mAh rechargeable | 650 mAh rechargeable | 850 mAh rechargeable | 600 mAh rechargeable |
| Charging | USB Type-C | USB Type-C | USB Type-C | USB Type-C |
| Coil | 0.4Ω Mesh Coil | 1.0Ω Mesh Coil | 1.0Ω Mesh Coil | Mesh Coil |
| How it works | DTL / MTL with airflow adjustment | Rotate the top selector to change flavor | Rotate the top selector to change flavor | Draw activated |
| Display | Battery, remaining e-liquid and current DTL / MTL mode | Battery and overall e-liquid level | Battery and overall e-liquid level | No display |
| Flavor setup | Single flavor, 8 current choices | 4 independent flavor positions, 21 listed flavors, about 10 combinations | 3 independent flavor positions, 10 listed combinations | Uses the buyer’s refill liquid |
| Refillable | No, pre-filled | No, pre-filled | No, pre-filled | Yes |
| Published nicotine | 6 mg/mL | 20 mg/mL | 20 mg/mL | Depends on the e-liquid added |
Those numbers make the range easier to understand than a list of puff ratings.
The NOVA 4in1 has four separate 10 mL flavor chambers, giving 40 mL in total. The top selector lets you move between four flavor positions without carrying four separate devices. Marsilen currently lists 21 flavors across about 10 four-flavor arrangements.
The NOVA 3in1 uses the same basic idea with three independent 5 mL chambers. Total liquid capacity drops to 15 mL, but its battery grows from 650 mAh on the 4in1 to 850 mAh.
That is a useful reminder that the biggest battery does not automatically get the biggest puff number. NOVA 3in1 has a battery that is 200 mAh larger:
850 mAh − 650 mAh = 200 mAh
Yet its published puff rating is 60,000 rather than 80,000. Liquid capacity, coil setup and the way the device is used also matter.
The Deimos goes in another direction. Marsilen’s specification lists 60 mL, a 1200 mAh rechargeable battery and a 0.4Ω mesh coil. It also supports DTL and MTL use with airflow adjustment. The screen shows battery level, remaining liquid and the active mode.

Then there is PRO 30K. It is the simplest of the four on paper: 600 mAh battery, mesh coil, draw activation, no screen and a 10 mL refillable pod. Marsilen publishes up to about 30,000 puffs across three fills.
Not sure which Marsilen format fits your order?
Send the destination, product type and expected quantity. For wholesale orders, Marsilen can check current stock, the available version and pricing for the actual market instead of giving you a generic answer.
What the Puff Numbers Can and Cannot Tell You
The puff figures are useful for comparing published specifications. They are not a stopwatch.
Take NOVA 4in1. If you divide its advertised 80,000 puffs by an assumed 800 puffs per day:
80,000 ÷ 800 = 100 days
The math is fine. That does not mean every device will last 100 days.
A person’s draw may be short or long. Use can be light one day and heavy the next. Airflow and power behavior also change consumption.
Deimos makes the point even clearer. Its published 200,000-puff figure is 2.5 times the NOVA 4in1 figure:
200,000 ÷ 80,000 = 2.5
That tells you the difference between the two published numbers. It does not prove that Deimos will last exactly 2.5 times longer for every user.
When VapeSourcing lists high-puff products from several manufacturers, the same rule applies. One brand’s “100K” figure and another brand’s “80K” figure may come from different testing assumptions. Unless the test conditions are comparable, the larger number is not an independent real-world result.
VapeSourcing Gives You More Product Types to Browse
VapeSourcing’s wider catalog is the clearest product difference between the two stores.
Its UK storefront currently separates products into reusable vapes, prefilled pod kits, vape kits, mods, atomizers, e-liquids, replacement pods, coils and accessories. It also carries a long list of manufacturers.
That makes it easier to shop across brands, but it creates a little more homework. Check who actually made the product and which version you are looking at.
A product called “Pro,” “Max” or “V2” may use a different battery, pod or coil from the model beside it. A replacement cartridge that looks right is not enough. The model number still needs to match.
There is another UK-specific point. The sale and supply of single-use vapes has been illegal across the UK since 1 June 2025. The ban covers both nicotine and non-nicotine single-use vapes and applies to online and physical sales.[3]
So when you browse VapeSourcing UK in 2026, its current reusable and prefilled-kit structure needs to be understood in that regulatory context. A product sold on another regional VapeSourcing site may not be the same version that can legally be sold in the UK.
Shipping: Start With the Warehouse
Marsilen’s current Shipping Policy says local warehouse orders typically take about 7 days after dispatch. The European warehouse also lists about 7 days after dispatch.
The European warehouse currently covers 24 countries:
Germany, Poland, France, Italy, Spain, Austria, Belgium, Bulgaria, Croatia, Czech Republic, Estonia, Finland, Greece, Hungary, Ireland, Latvia, Lithuania, Luxembourg, Netherlands, Portugal, Romania, Slovakia, Slovenia and Sweden.
Other supported destinations may ship from China through FedEx International. Marsilen says remote areas and customs can add time.
VapeSourcing UK uses UK, EU and CZ warehouse routes. Its current shipping page lists:
| Destination | VapeSourcing UK published estimate |
|---|---|
| UK | 1–4 working days |
| Europe | 5–7 working days |
| Rest of world | 15–20 working days |
These are VapeSourcing UK figures. They should not be copied onto its U.S., Japanese or other regional storefronts.
VapeSourcing UK also publishes same-day dispatch for qualifying Royal Mail orders placed before its weekday cut-off. Again, dispatch and delivery are two different things.
“Dispatched today” does not mean “delivered today.”
For example, two business days of warehouse processing plus seven business days of transit gives roughly nine business days before any unusual delay:
2 + 7 = 9 business days
For U.S. internet sales generally, the Federal Trade Commission requires sellers to have a reasonable basis for the shipping time they advertise. If a seller gives no shipping time, it generally needs a reasonable basis to expect shipment within 30 days. Delay, cancellation and refund requirements can apply if that timing cannot be met.[1]
Tracking Is Only Part of the Delivery Story
A tracking number may appear before a carrier makes the first physical scan. Cross-border tracking can also sit still for a while when a parcel moves between networks.
Marsilen currently tells customers to contact support if a parcel has not arrived within 25 working days after shipment.
25 working days = about 5 standard working weeks
That is the point for escalating an overdue order, not the usual delivery time.
If a Marsilen shipment looks stuck, the Help Center is the practical place to start. Keep the order number and tracking number handy.
Need to know which warehouse can serve your order?
For a larger order, send the destination and exact Marsilen model before you work from a general delivery estimate. Stock location can change the route, freight cost and final delivery time.
International Vape Shipping Has Extra Limits
Vapes are not handled like ordinary clothing or phone accessories.
USPS states that electronic nicotine delivery systems are nonmailable in inbound and outbound international mail. Domestic exceptions listed by USPS do not apply to those international shipments.[2]
So a website accepting an address does not automatically mean every carrier can legally move that product to the destination.
Marsilen also states that import duties, VAT and other customs charges may remain the customer’s responsibility. Buyers are asked to check local customs rules before ordering.
Returns: 14 Days Is Not the Same as 48 Hours
Marsilen uses separate deadlines depending on what happened to the order.
| Situation | Current Marsilen term |
|---|---|
| Eligible change-of-mind return | Within 14 days of receipt |
| Defective, damaged or incorrect delivery | Report within 48 hours |
| Initial response to return request | Within 1 working day |
| Approved refund after inspection | 7–14 working days |
The Marsilen Return and Refund Policy says a normal change-of-mind item needs to stay unopened, unused and in its original undamaged packaging.
For hygiene reasons, e-liquids, disposable e-cigarettes and cartomizers or atomizers only qualify for a change-of-mind return while unopened and sealed. A genuine defect or wrong item is handled separately.
The difference between the two main clocks is big:
14 days = 336 hours
48 hours = 2 days
If a parcel arrives damaged, waiting a week because you remember seeing “14 days” on the return page is a bad idea. Photograph the product, carton and shipping label when you open it and report the problem promptly.
VapeSourcing Warranty Depends on the Product
VapeSourcing’s regional structure makes after-sales rules less uniform.
Its UK storefront currently lists different warranty periods for different product types:
| VapeSourcing UK product type | Published condition |
|---|---|
| Coils and pod cartridges | Material-defect claims within 3 days after receipt |
| E-liquids | Damage on arrival |
| Atomizers / tanks | 3 months from delivery |
| Batteries / mods | 6 months from delivery |
| Charging equipment | 6 months after receipt |
| Disposable vape kits | Damage on arrival |
For ordinary non-faulty returns, the UK policy excludes e-liquid and disposable vapes. Other eligible items need to stay unopened with the outer seal intact.
Missing or incorrect-item claims on that storefront should currently be reported within 48 hours of delivery.
So there is no useful global statement such as “VapeSourcing has a six-month warranty.” Six months applies to some hardware on the UK storefront, not every item sold by every regional site.
A Defect Report Is Better With Numbers
Imagine a store receives 500 units and 12 have the same charging problem.
12 ÷ 500 × 100 = 2.4%
You can tell support that the shipment has a 2.4% observed issue rate.
Do not turn that into “the brand has a 2.4% defect rate.” It is one shipment, not a factory-wide statistic.
For a useful claim, keep:
- the order number;
- the exact model and SKU;
- the total number received;
- the number affected;
- batch or package details if available;
- photos of visible damage;
- a short video for a functional fault;
- the steps already tried.
Marsilen asks customers to include the order number and supporting photos or video where needed. VapeSourcing UK asks for similar details, including product name, serial number, problem description and visual evidence.
Do Not Mistake a Policy for Service Performance
A return page can tell you that a claim should be filed within 48 hours. It cannot tell you how happy customers are with the result.
Neither retailer publishes enough independent data to make a solid comparison of:
- average support response time;
- average resolution time;
- overall device defect rate;
- percentage of orders delivered on time;
- refund approval rate.
Marsilen currently says its wholesale team targets a reply within one business day. That is useful when sending an enquiry, but it is still a published target rather than an independently measured average.
Wholesale Buyers Should Look Past the Unit Price
This is where small differences become real money.
Imagine two quotes for 1,000 units:
| Illustrative cost | Supplier A | Supplier B |
|---|---|---|
| Product price | $8.20 | $8.70 |
| Freight per unit | $0.95 | $0.45 |
| Import / local handling | $0.40 | $0.25 |
| Landed cost | $9.55 | $9.40 |
Supplier A looked $0.50 cheaper at first. Once the example freight and handling are added, Supplier B is $0.15 cheaper.
$9.55 − $9.40 = $0.15 per unit
1,000 × $0.15 = $150
These numbers are examples, not live Marsilen or VapeSourcing quotations.
A $0.50 difference also gets bigger quickly:
- 500 units = $250;
- 1,000 units = $500;
- 5,000 units = $2,500.
The lower product price only saves money if freight, import costs and problem stock do not eat up the gap.
Ask What the MOQ Applies To
Marsilen’s wholesale program does not publish one MOQ for every device. Larger business terms depend on the model, order size, market and current stock.
That is worth checking because “MOQ 100” can mean very different things.
If 100 units can be mixed across several flavors, you buy 100.
If it means 100 units for each of 10 flavor combinations:
100 × 10 = 1,000 units
If two nicotine strengths are treated as separate SKUs:
100 × 10 × 2 = 2,000 units
Ask whether the MOQ applies per order, model, flavor, nicotine strength or SKU. One short question can change the opening inventory requirement by hundreds or even thousands of units.
Have a quantity and market in mind already?
Send Marsilen the exact product, destination and expected quantity. If you need a specific nicotine level, package version or business document, add that to the same enquiry so the quote is based on the version you actually need.
Market Version Matters
A global product page is not proof that the same device can be sold in every country.
For relevant nicotine-containing e-cigarettes in the EU, Article 20 of Directive 2014/40/EU limits nicotine-containing liquid to 20 mg/mL. Dedicated refill containers are limited to 10 mL, while relevant cartridges and tanks are limited to 2 mL.[4]
That does not mean you can look at one number on a global product page and decide whether the product is compliant. Product format, market version, packaging, notification status and national rules still matter.
For wholesale orders, confirm:
- exact SKU;
- nicotine strength;
- liquid and pod configuration;
- retail packaging;
- destination market;
- available product documents.
This is especially important when the same product name appears in more than one country.
U.S. Buyers Have Separate Age Rules
In the United States, federal law prohibits retailers from selling tobacco products, including e-cigarettes, to anyone under 21. FDA rules also require retailers to check photo ID for anyone under 30 who tries to buy covered tobacco products.[5]
Other markets use their own age, product and sales rules. A retailer’s checkout page is not a substitute for checking the rules that apply where the product will actually be sold.
Product Specs Are Not Health Claims
A 1200 mAh battery, 0.4Ω coil or 200,000-puff rating tells you something about the published device specification. It does not show that the product is safer.
CDC states that there are no safe tobacco products, including e-cigarettes, and advises adults who have never smoked or used other tobacco products not to start. CDC also notes that most e-cigarettes contain nicotine.[6]
The same care should be used with wording such as “smooth,” “stronger” or “better performance.” Those phrases should not be turned into health or risk claims.
Battery Problems Need a Simple Response
FDA says reported vape battery fires and explosions appear uncommon but can cause serious injuries. Its guidance recommends using the correct charging equipment, charging on a clean flat surface away from flammable materials and avoiding extreme temperatures.[7]
If a rechargeable device becomes unusually hot, swollen or visibly damaged, stop using and charging it.

FAQ
Is Marsilen the same type of store as VapeSourcing?
No. Marsilen mainly sells its own products. VapeSourcing is a multi-brand retailer with a much wider list of manufacturers.
Which Marsilen device has the largest published capacity?
Among the four models compared here, the current Marsilen specification lists Deimos at 60 mL with a 1200 mAh rechargeable battery. NOVA 4in1 lists 40 mL total, NOVA 3in1 lists 15 mL total and PRO 30K uses a 10 mL refillable pod.
Which Marsilen model gives the most flavor choices in one device?
NOVA 4in1 has four selectable flavor positions. Marsilen currently lists 21 flavors across about 10 four-flavor combinations. NOVA 3in1 has three flavor positions.
Which one ships faster, Marsilen or VapeSourcing?
There is no reliable independent head-to-head delivery dataset. Marsilen currently publishes about 7 days after dispatch for its listed warehouse routes. VapeSourcing UK currently lists 1–4 working days for UK delivery, 5–7 for Europe and 15–20 for the rest of the world. Those VapeSourcing numbers apply to the UK storefront.
How quickly should a damaged Marsilen order be reported?
Marsilen currently asks customers to report defective, damaged or incorrect deliveries within 48 hours. Eligible unopened change-of-mind returns use a separate 14-day period.
What should a wholesale buyer compare first?
Start with the exact SKU, destination, quantity, MOQ rule and warehouse. Then calculate landed cost. A $0.50 difference already becomes $500 across 1,000 units.
Bottom Line
Marsilen is easier to compare when you already know you want one of its product formats. NOVA 4in1 gives four independent flavor positions and 40 mL total capacity, NOVA 3in1 uses three 5 mL chambers and a larger 850 mAh battery, Deimos moves to a 60 mL dual-mode setup with a 1200 mAh battery, and PRO 30K is the refillable option. VapeSourcing gives you far more brands, but shipping and warranty terms depend more heavily on the regional store and product type. Before paying, check the exact SKU, warehouse and claim deadline. For wholesale orders, add MOQ, market version and landed cost to that list.
