Ac Adapter Power Supply Cord For Tech 21 bsdr Bsdr-v2 Sansamp Bass
Lower concern, standard power adapter with no known PFAS application
AC power adapters typically use copper wire, plastic housing, and rubber insulation with minimal PFAS risk. Tech21 makes no PFAS disclosures; no red flags identified in standard construction.

The full breakdown
What it's made of and why it matters
This adapter consists of a plastic external housing enclosing a transformer with copper windings and internal metal conductors, plus rubber or PVC insulation around the cord. The plastic housing is molded to protect internal components and insulate the user from electrical hazard; rubber or PVC cord insulation is standard for low-voltage applications like this bass amplifier supply. No exotic materials or known problematic coatings are used in typical Tech 21 power supplies of this type.
The brand's record and disclosure
Tech 21 is a well-established audio equipment manufacturer without documented safety recalls or disclosure statements specific to their power adapters. The company does not publicly advertise material certifications or PFAS policies on this product line. No major controversies or safety findings have been published regarding their standard power supply cords. Brand transparency on chemical composition is minimal but typical for this product category.
How it compares in its category
Power adapters for musical equipment are largely commoditized, and this falls within normal construction standards. Most third-party and OEM supplies use identical plastic and rubber materials without differentiation. Tech 21's offering is neither above nor below typical market safety profiles for this application. No credible evidence suggests their adapters pose greater or lesser risk than generic equivalents.
If you buy it
Keep the cord away from heat sources and pinching to preserve insulation integrity. Inspect regularly for cracks, exposed wires, or discoloration; discard immediately if damage is visible. Avoid wrapping tightly around sharp corners or the adapter itself, as cord stress can degrade insulation over years of use. Replace the cord if it becomes warm during normal operation or shows any sign of degradation.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Cord insulation degradation over time
Rubber and PVC insulation can crack, harden, or peel with age, flexing, heat exposure, or UV light. Once exposed, internal conductors pose electrical shock risk. This is a function of use conditions and product age, not a manufacturing defect in this adapter.
Plastic housing leachables under heat stress
No known heavy metals, BPA, or other leachables have been reported in Tech 21 adapter housings. Typical plastic used in power supplies is ABS or similar; risk would only apply if the adapter overheats due to malfunction, which is rare in this product class.
Internal component failure / electrical hazard
Manufacturing defects in the transformer or circuitry could theoretically cause overheating or short-circuiting, but no recalls or safety advisories exist for this specific model. Standard electrical safety testing applies to all power adapters sold in regulated markets.
Counterfeit or aftermarket substitution risk
Third-party sellers may supply inferior copies with lower insulation quality or unregulated plastic that could release fumes or fail electrically. Verify you are purchasing from an authorized Tech 21 distributor to mitigate this risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
