| 1 | Confirm legal compliance | Check whether the product is legally permitted in the country or region where it will be sold and used. | Applicable national tobacco, consumer-product, electrical-safety, packaging, and age-restriction requirements. | The seller cannot identify the responsible importer, local distributor, or required market authorization. | Check the official health or regulatory authority in your jurisdiction before purchasing. |
| 2 | Inspect the safety labeling | Look for warnings, nicotine information, ingredients, manufacturer or importer details, batch identification, and disposal instructions. | Labels should be legible, durable, locally required, and consistent with the product packaging. | Spelling errors, missing warnings, unclear nicotine strength, or labels applied only with a loose sticker. | Compare the device, box, leaflet, and online listing for matching information. |
| 3 | Verify product authenticity | Check the batch number, serial number, tamper-evident seal, and official verification method where available. | Codes should be unique, readable, and accepted by the authorized verification channel. | Repeated codes, damaged seals, mismatched packaging, or a verification page that asks for unusual personal or payment information. | Keep the receipt and photograph the packaging before opening it. |
| 4 | Review battery protection | Check for protected charging, overcharge protection, short-circuit protection, overheating control, and a stable battery enclosure. | Clear charging instructions and evidence of relevant electrical or battery-safety testing from a competent laboratory. | A damaged, swollen, hot, leaking, or unusually loose battery; exposed wires; or charging without safety instructions. | Use only the supplied or specified charger, and never charge the device on a bed or unattended overnight. |
| 5 | Check electrical certifications carefully | Determine whether displayed conformity marks apply to the complete product and the destination market. | A traceable declaration of conformity, test report, or certification from a recognized and competent assessment body. | Unexplained logos, copied certificate numbers, or claims that a single mark proves overall product safety everywhere. | Search the issuing body or regulator when a certification claim is important to your purchase decision. |
| 6 | Assess e-liquid information | Review nicotine concentration, ingredient disclosure, volume, lot number, expiry or best-before information, and child-resistant packaging where required. | The liquid information must match the cartridge or bottle and comply with local labeling and concentration rules. | No ingredient list, leaking container, unclear nicotine units, or a nicotine claim that differs between the box and device. | Avoid contact with skin and eyes; nicotine liquid can be toxic if swallowed or absorbed. |
| 7 | Evaluate construction quality | Inspect the mouthpiece, tank or pod connection, seals, airflow openings, charging port, and activation control. | Parts should fit securely, operate consistently, and show no cracks, sharp edges, residue, or fluid leakage. | Loose components, persistent gurgling, burnt odor, automatic firing, or liquid around the battery area. | Stop using any device that becomes unusually hot, leaks, or activates without deliberate operation. |
| 8 | Check age and marketing controls | Confirm that the seller applies the legal minimum-age requirement and does not market the product to minors. | Responsible sales practices, age verification, and marketing that avoids youth-oriented imagery or unauthorized health claims. | Cartoon imagery, candy-style promotion, sales to minors, or claims that vaping is harmless. | Keep all devices and nicotine liquids away from children and animals. |
| 9 | Review after-sales support | Check the return policy, warranty period, safety-recall process, user manual, and access to replacement parts or compatible pods. | A traceable seller, written warranty terms, safety contact information, and clear instructions in the local language. | Cash-only sales, no receipt, no safety contact, or a seller that refuses returns for defective products. | Buy from a retailer that can provide documentation and respond to safety complaints. |
| 10 | Plan responsible disposal | Determine how the battery, device, cartridges, and e-liquid container should be disposed of in your area. | Local household hazardous-waste, battery-recycling, or electronic-waste guidance. | Instructions to burn, crush, puncture, or place lithium-battery devices in ordinary household waste. | Do not puncture or incinerate the device; use an approved battery or electronic-waste collection point. |
