Key Factors When Buying Empty Vape Pens
Atomizer Technology
Modern wickless ceramic atomizers are considered the gold standard, offering superior taste, reduced burning, and increased safety compared to outdated wick-based designs [o2vape.com].
⚠️ Avoid: Cotton, fiberglass, or carbon fiber wick cartridges – they’re prone to leaking and burning

Most cartridges come in 0.5ml and 1ml sizes, with growing popularity of 2ml options. Larger capacities like 2g disposables are trending for their convenience [VPM].
- 0.5ml: Compact, portable, good for testing
- 1ml: Most popular, best balance of size and capacity
- 2ml: Longer-lasting, fewer refills needed
Closure Types
Choose between screw-on caps for easy refilling or press-fit tamper-evident seals for retail products. Many sites offer both options [Packlahoma].

Authenticity, Testing, and Shipping in the USA
Why Heavy Metals Testing Matters
The vape industry has seen serious issues with toxic cartridges failing safety requirements. Always verify that your supplier provides verifiable heavy metals testing for lead, arsenic, mercury, cadmium, chromium, nickel, and copper [o2vape.com].
What to Look For:
- Recent lab test certificates (within 6 months)
- Third-party testing from accredited labs
- Transparent COA (Certificate of Analysis) documents
- Batch-specific testing results

US Shipping Advantages
All recommended sites ship from US warehouses, ensuring fast delivery (typically 2-5 business days), better customer service, and easier returns compared to overseas suppliers. This also reduces the risk of customs delays and quality control issues.

Frequently Asked Questions
Empty vape cartridges (510 thread) require a separate battery and can be refilled multiple times. Empty disposable vape pens include a built-in battery and are typically single-use. Cartridges are more cost-effective for regular users, while disposables are better for retail products or one-time use.
Look for suppliers that provide heavy metals testing certificates from accredited labs. Avoid cartridges with cotton, fiberglass, or carbon fiber wicks. Choose reputable sites like O2VAPE, VPM, or VapePensWholesale that explicitly mention safety testing and use materials like glass, ceramic, or stainless steel.
For thin oils (e-juice consistency): 0.9-1.2mm holes. For medium viscosity (distillate): 1.2-1.6mm holes. For thick oils (live rosin, RSO): 1.6-2.0mm holes. Using the wrong size can cause leaking (hole too big) or poor flow (hole too small).
The best wholesale sources include VapePensWholesale (lab-tested, US shipping), Packlahoma (cannabis business focused), and Budtank Wholesale (customization options). Always request samples first and verify testing certificates before placing bulk orders.
Most empty 510 cartridges work with any 510-thread battery, but voltage matters. Ceramic cartridges work best with 3.7V+ batteries, while older wick designs need lower voltages (under 3.3V). Always check the cartridge specifications and match the voltage for optimal performance.
