How to choose empty disposable carts for cannabis oil brand？

Creating high-quality cannabis oil is only part of the equation—pairing it with reliable empty disposable carts is just as important. Poor-quality carts can lead to leaks, clogging, and poor vapor production, resulting in dissatisfied customers and lost sales.

To compete in the market, cannabis oil brands must invest in both premium oil and well-engineered vape hardware. The right combination improves user experience, encourages repeat purchases, and boosts profitability.

Here’s what to consider when selecting empty disposable cart suppliers.

Determining Vape Hardware Specifications: Style, Capacity, Functionality, Material Requirements

• Step 1: Choose the Right Battery System Based on Market Demand

  The first step in selecting empty disposable carts is deciding on the battery system that best fits your market. The three main options are:

  • Disposable Vape Pens – Convenient, pre-filled, and ready to use.
  • 510 Thread Cartridges – Versatile and compatible with various batteries.
  • Pod Systems – Designed for specific pod-based vape devices.

  Choose the option that aligns with your brand’s positioning and customer preferences.

  Step 2: Determine the Ideal Cartridge Capacity

  The capacity of empty disposable carts typically ranges from 0.5ml to 6ml. However, it is recommended not to exceed 5ml, as larger capacities may lead to:

  • Clogging issues due to oil thickening.
  • Incomplete vaporization, resulting in wasted product.
  • Unpleasant odors from overheating and residue buildup.

  For optimal performance and customer satisfaction, choose a size that matches your oil’s characteristics and intended use.

  Step 3: Select a Ceramic Heating Coil Based on Oil Type

  The heating coil plays a critical role in vaporizing the oil efficiently. In 2024, full-ceramic cartridges (without a metal center post) are gaining popularity because they:

  • Enhance vaporization quality by ensuring even heating.
  • Eliminate metal contact, preserving pure flavor.
  • Reduce concerns about heavy metals, improving safety and compliance.

  When selecting empty disposable carts, prioritize models with full-ceramic technology for better user experience and product consistency.

• 

• Step 4: Choose a Variable Voltage Battery Based on Oil Characteristics

  Different cannabis oils require different voltage settings for optimal vaporization. Selecting the right voltage range ensures smooth vapor production and preserves flavor.

  • Live resin carts typically require a three-mode adjustment between 2.2V and 3.0V for optimal performance.
  • Delta-8 THC pens perform best with a three-mode adjustment between 3.0V and 3.7V to efficiently vaporize the thicker oil.

  Choosing adjustable voltage batteries allows users to customize their vaping experience based on the oil’s properties.

  Step 5: Select the Right Oil Intake Hole Size for Oil Viscosity

  The size of the oil intake hole significantly affects vaporization efficiency.

  • For high-viscosity oils, carts with a center post should have intake holes between 1.8mm and 2.0mm to ensure proper absorption and prevent clogging.
  • Bottom full-ceramic heating chambers provide a better solution, as they function like a funnel-shaped flat-bottomed pan, allowing oil to be absorbed and vaporized efficiently without the need for multiple intake holes.

  Step 6: Keep Up with Evolving Hardware Trends

  Vape technology is constantly advancing, and staying updated with the latest features can help brands stay competitive.

  • Adjustable voltage displays were previously a major selling point.
  • In 2024, new trends include electronic display screens that show:
    • Battery level
    • Puff count
    • Custom brand logos

  Integrating these features into empty disposable carts can enhance the user experience and add value to your brand.

Collecting Samples and Finding Suppliers

Before finalizing a supplier, it’s essential to gather samples of different empty disposable carts available in the market. This allows you to evaluate quality, functionality, and compatibility with your cannabis oil. There are three main sourcing channels to consider:

Local Wholesalers

• Quick access to bulk empty disposable carts and vape pens.
• Ideal for small-scale purchases (below 5,000 units per month).
• Higher costs compared to sourcing directly from manufacturers.
• Limited customization options, as most wholesalers stock standard designs.

Local wholesalers are a good choice for small businesses looking for immediate stock without the need for extensive customization.

Chinese Factories

• Best for businesses purchasing over 5,000 units per month.
• Direct access to the latest vape cartridge designs at factory prices.
• Full customization options (logo printing, packaging, voltage settings, and materials).
• Lower costs per unit, making it more profitable for long-term growth.

If you need large volumes and want to keep procurement costs low, sourcing from Chinese factories is the best option.

Chinese Trading Companies

• Suitable for brands that need a variety of customized products but don’t meet high MOQs.
• One-stop procurement support, offering multiple product options from different manufacturers.
• Slightly higher prices than factory-direct sourcing but more flexibility in product selection.

For brands that want customization without committing to large orders, Chinese traders offer a balanced approach.

By comparing samples from these different channels, you can determine which supplier best meets your quality, pricing, and customization needs.

How to Find Empty Vape Cartridges Manufacturers from China?

Before September 2022, China has approximately 4000 electronic cigarette manufacturing enterprises of various sizes. After September 2022, the Chinese government issued Electronic Cigarette Production Licenses to qualified enterprises, with over 400 companies obtaining this license and ordering the closure of all unlicensed electronic cigarette factories. Please make sure that your Chinese manufacturer has the following legal production licenses.

 

Alibaba and Made in China have already blocked suc products. Currently, there are only three ways to find Chinese factories:

Trade Shows: Attend exhibitions such as CHAMPS Trade Shows, MJBizCon, and Tobacco Product Expo.

Google Sources: Search for Chinese electronic cigarette factory websites.

Social Media: Utilize platforms like LinkedIn, Facebook, and Instagram.

Product Testing and Evaluation for Empty Disposable Carts

Ensuring the quality of empty disposable carts is essential before committing to a supplier. Even without a professional testing facility, you can conduct effective evaluations using the following steps:

Step 1: Visual Inspection

• Examine the build quality and craftsmanship for any visible defects.
• Check for scratches, dents, or misaligned parts in electric pens and cartridges.

Step 2: Drop Test for Durability

• Drop several empty disposable carts from a height of 1.2 meters to test for breakage.
• Assess whether the product remains intact and functional after impact.

Step 3: Oil Filling and Capping Test

• Evaluate whether cartridges are easy to fill with oil.
• Ensure secure and leak-proof capping to prevent spills during storage and transportation.

Step 4: Leakage Test

• Fill the empty disposable carts with oil and let them sit for 48 hours.
• Check for any leakage, seepage, or condensation around the cartridge.

Step 5: Usage and Vaporization Test

• Assess flavor quality, vapor production, and aroma after filling.
• Check for any burnt or off-flavors during use.
• Record the puff count on a full charge—0.5ml and 1ml carts should ideally function without recharging.
• Evaluate whether the cart fully vaporizes the oil without leaving residue.
• Test for clogging issues or oil leakage into the mouthpiece.
• Verify the effectiveness of preheating functions, ensuring oil flows smoothly in low temperatures.
• Test different voltage settings (high, medium, low) to confirm they work as intended.

Step 6: Packaging, Storage, and Transport Evaluation

• Assess the ease of packaging and storage to ensure the product remains secure.
• Simulate shipping conditions to confirm no leakage or damage occurs during transport.

After testing, select at least three qualified suppliers and create a comparison table to assess their performance.
