Smart USB Charger
Skip until waterproof treatment ingredients disclosed.
Smart USB chargers often use waterproof coatings that may contain PFAS. Waterproof Co. does not disclose coating composition or PFAS status, creating uncertainty.

The full breakdown
What it's made of and why it matters
This charger uses unspecified plastic housing with an undisclosed waterproof coating. The plastic shell likely contains common polymers (ABS, polycarbonate, or polyethylene), which are generally stable during normal use but can degrade if exposed to heat, UV, or mechanical stress. The waterproof treatment is the critical unknown: water-resistant coatings often rely on Teflon-family coating (PFAS-based) or other chemicals that may leach into hands or nearby surfaces over time, especially if the coating chips or degrades.
The brand's record and disclosure
Waterproof Co. has not publicly disclosed the specific chemistry of its waterproof coating or provided third-party safety certifications for this product. This silence on material composition is a significant transparency gap, particularly for a water-resistant device that may contact skin frequently. No established recalls or safety violations are on record for this brand, but the lack of proactive disclosure limits confidence in ingredient safety.
How it compares in its category
Most mainstream USB chargers avoid waterproof coatings altogether, relying instead on sealed enclosures and conformal electronics coating (non-fluorinated options exist). Brands that do market waterproof chargers typically disclose their coating type and safety testing; Waterproof Co.'s silence puts it at a disadvantage against competitors with transparent material sourcing. This product sits in a niche where waterproofing is a selling point but safety documentation is weak.
If you buy it
Avoid prolonged skin contact with the housing; keep it away from heat sources (direct sun, hot car interiors) to minimize any coating degradation and potential leaching. Do not submerge the entire unit in water unless your specific model is certified IP67 or IP68 with published test reports. Inspect the coating regularly for cracks, peeling, or discoloration; if visible damage occurs, discontinue use and replace. Request material safety data sheets (MSDS) from the retailer or manufacturer before purchase if possible.
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.”
Undisclosed waterproof coating leachables
Waterproof treatments on consumer electronics often contain fluorochemicals or other additives; without ingredient disclosure, leaching risk cannot be ruled out, especially if coating is damaged or heated.
Plastic off-gassing and degradation
Unspecified plastic housing may emit volatile organic compounds (VOCs) during manufacturing or under heat stress; long-term stability and potential for microcracking is unknown without material certification.
Coating chip and micro-inhalation risk
If waterproof coating degrades or flakes during use or storage, small particles could be inhaled or ingested, particularly if product is handled frequently or stored near food.
Electrical safety in moisture exposure
No safety recalls recorded; however, waterproof claims should be verified against published IP ratings and third-party testing to ensure electronics are adequately isolated from water ingress.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
