Tech21 Wireless Charger
Lower concern. Wireless chargers rarely use PFAS coatings.
Tech21 wireless chargers use standard plastic and metal electronics with no disclosed water-resistant coatings. No PFAS risk signals identified for typical device use.

other is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
Tech21 wireless chargers use standard thermoplastic housing (likely polycarbonate or ABS), copper/aluminum induction coils, and standard circuit board components. The plastic casing is not a high-heat exposure surface during normal operation, so degradation and leaching risk is low. No coating, glaze, or fabric component means absence of common plastic-category hazards like BPA or phthalates in contact with food or skin.
The brand's record and disclosure
Tech21 is a widely distributed consumer electronics accessory brand with no publicly documented safety recalls or material disclosure failures on wireless chargers. The company does not explicitly publish material composition or chemical safety statements, which is typical for this product category but leaves some ambiguity. No known controversies regarding heavy metals, allergens, or hazardous substance use in their charger lines are on record.
How it compares in its category
Wireless chargers are among the lowest-risk electronics categories because they contain no coatings, adhesives, flame retardant treatments, or thermal stress components that trigger off-gassing. Tech21's design is representative of standard market offerings with no known material shortcuts or cost-cutting that would elevate hazard profile compared to competitors like Belkin or Anker.
If you buy it
Keep the charger away from sustained heat sources and do not block ventilation slots, as internal coil operation generates modest warmth. Do not immerse or expose to water despite splash resistance claims; moisture can corrode coils. Replace if the plastic casing cracks, as this could expose internal metal parts. Standard electronics recycling at end of life prevents landfill leaching of trace metals in circuit components.
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.”
Plastic housing degradation and leaching
ABS or polycarbonate casing is not in direct contact with skin or food and operates at low temperature. No established leaching of BPA, phthalates, or other plasticizers has been reported for this product class under normal use.
Electromagnetic field (EMF) exposure
Wireless chargers emit non-ionizing radiofrequency energy within FCC/CE regulatory limits. No credible evidence links exposure at charger distance to health harm; this is a regulatory compliance issue, not a material hazard.
Coil corrosion and metal leaching
Copper and aluminum coils can corrode if the housing is cracked or moisture enters, potentially releasing trace metals. Risk is minimal under dry conditions but increases if water exposure or physical damage occurs.
Fire or thermal runaway from defective electronics
Tech21 chargers must meet UL or equivalent safety standards for overcurrent protection and thermal shutdown. No recall history for fire hazard is on record, indicating standard safety margins are met.
Off-gassing from circuit board soldering or potting materials
Circuit boards may use lead-free solder and epoxy potting compounds; these do not off-gas volatile organic compounds under normal operating temperature (below 50°C for housing exterior).
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.
