Outdoor Products Large SmartPhone Watertight Phone Case
Skip. Waterproof coating composition undisclosed, PFAS risk unclear.
Anccer smartphone cases use waterproof treatments but provide no material transparency or PFAS claims. Standard waterproof polymer cases often contain PFAS; no independent verification available.

The full breakdown
What it's made of and why it matters
This case uses an unspecified polymer shell with a waterproof sealing treatment of unknown chemical composition. Waterproof coatings on polymer housings are typically polyurethane, acrylic, or silicone-based, but Anccer does not publicly disclose which. The critical unknown is whether the sealing treatment contains fluorinated compounds (PFAS) for water repellency, which cannot be determined from available product information. Polymer degradation from UV, temperature cycling, and mechanical stress can release oligomers and plasticizers into contact surfaces over time.
The brand's record and disclosure
Anccer is a Chinese smartphone accessory manufacturer with no publicly established safety certifications, material transparency reports, or independent third-party testing on file for this product line. The brand has not issued statements regarding PFAS use, heavy metals in dyes or coatings, or compliance with EU REACH or similar regulatory frameworks. No major product recalls or safety controversies are documented in public health databases, but absence of disclosure is not the same as absence of risk. This silence means consumers cannot verify whether waterproof treatments meet any recognized safety standard.
How it compares in its category
Waterproof phone cases range from rigid polycarbonate shells to soft TPU (thermoplastic polyurethane) options; this Anccer product's exact resin type is not specified, limiting direct comparison. Premium brands (Lifeproof, OtterBox) typically disclose polymer composition and undergo third-party durability testing, while budget-tier cases like this one often do not. The lack of material transparency is the primary differentiator and risk factor relative to competitors at similar price points. Mid-range alternatives often provide material datasheets or at minimum confirm absence of BPA; Anccer does not.
If you buy it
Keep the case away from direct sunlight and heat sources above 140°F (60°C) to slow polymer degradation and coating breakdown. Inspect the sealing gasket and coating quarterly for cracks, discoloration, or peeling; replace the case if visible damage appears, as waterproofing integrity cannot be repaired. Avoid prolonged contact between the case and prolonged skin contact on very hot days, as leaching of degradation byproducts increases with temperature. Rinse with plain water after saltwater or chlorinated pool use and air-dry completely before sealing; standing water inside can promote bacterial growth if gaskets trap moisture.
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 composition
The sealing treatment is not chemically specified by Anccer. If Teflon-family coating-based, PFAS exposure is possible; if acrylic or polyurethane, volatile organic compounds (VOCs) and residual monomers may leach under heat or UV. Without testing, risk cannot be ruled out.
Polymer shell degradation and oligomer leaching
Unspecified polymer housings degrade under UV, temperature cycling, and mechanical stress over 12-24 months, releasing small molecular fragments and plasticizers onto skin and device. This is common in budget phone cases but exacerbated by undisclosed material grade.
Microplastic shedding from coating wear
Waterproof coatings can flake or shed microparticles as they degrade, particularly at seams and corners. Ingestion risk is low but skin contact and inhalation of coating dust during handling of worn cases is possible.
Dye or pigment heavy metals in case coloring
No documented incidents or testing of Anccer cases for lead, cadmium, or chromium in pigments. Standard for budget polymer cases, but not independently verified for this product.
Bacterial or mold growth in sealed gasket chambers
Trapped moisture between the waterproof seal and the case interior can harbor bacteria, mold, or mildew if not fully air-dried after wet use. This is a maintenance issue rather than a manufacturing hazard but is specific to waterproof case design.
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.
