Before a product shortlist
Verification checklist
- Verify the exact model, power requirements, intended location, warnings, and current seller.
- Treat certification as claimed until the exact product record is matched with the issuing body.
- Search the CPSC recall database and record the date; a no-match result is not a safety guarantee.
- Stop use if the product becomes unusually hot, damaged, discolored, loose, or electrically unstable.
