The full breakdown
What it's made of and why it matters
This multi-port charger has a plastic housing with an unspecified waterproof coating or sealant. The coating is the critical unknown: waterproof seals on consumer electronics frequently rely on fluorinated compounds (PFAS) or other hydrophobic polymers to block moisture ingress. The internal circuitry and ports are standard electronic components (copper contacts, circuit board resins). The plastic housing itself, if polycarbonate or ABS, is generally stable at room temperature but can degrade or leach if subjected to heat, UV, or physical stress over time.
The brand's record and disclosure
Smartdevil is a smaller consumer electronics brand with no established public record of material transparency, safety certifications, or third-party testing disclosures. No independent recalls or safety controversies are documented for this specific model. The brand provides no stated information about waterproof coating composition, flame-retardant treatment of housing, or compliance with electrical safety standards (UL, CE marking status is unclear). Absence of disclosure does not confirm hazard, but it limits assessment.
How it compares in its category
Multi-port USB chargers from established brands (Anker, Belkin, Samsung) typically publish safety certifications and material specifications; Smartdevil does not. The waterproof feature is less common than sealed but not explicitly waterproof designs, which generally use silicone gaskets or simple coating rather than PFAS-heavy encapsulation. The 8-port configuration and portable form factor put it in the mid-budget segment where cost-cutting on materials disclosure is routine.
If you buy it
Keep the charger in cool, dry conditions away from direct water exposure despite the waterproof claim; submerging it is not advised even if labeled waterproof. Do not expose to heat above 60C (140F), as plastic housing can warp and coatings can degrade, potentially releasing trapped compounds. Inspect the housing and port contacts regularly for cracks, discoloration, or corrosion; replace if any develop. Avoid prolonged contact with skin if the coating begins to visibly deteriorate.
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.”
Waterproof coating composition (unknown PFAS risk)
The manufacturer does not disclose the waterproof sealant or coating chemistry. Waterproof coatings on consumer electronics commonly use PFAS-based Teflon-family coating or polyurethane; this is not confirmed for this model but represents the primary non-PFAS-graded concern. Leaching from deteriorated coatings is unlikely during normal use but cannot be ruled out.
Plastic housing degradation and leachables
ABS or polycarbonate housing under normal room-temperature storage poses minimal leaching risk for BPA or phthalates. No recalls or reports of degradation-related issues are documented for this model. Risk increases if charger is stored in hot environments (car, direct sun) or physically damaged.
Electrical safety and overheating
Multi-port chargers, especially in budget segments, can present overcurrent or thermal runaway risk if internal protection circuits are inadequate. No test data is available for this model. Always use with UL-listed or CE-marked power adapter; charger should not become hot to the touch during normal operation.
Port contact corrosion or bacterial growth in sealed design
Waterproof sealing can trap moisture if the charger is exposed to water and not fully dried, creating conditions for corrosion or mold growth inside ports. This is a design risk rather than a material toxicity risk but can compromise safety and function. Dry thoroughly after any water contact.
Off-gassing from internal circuit board resins or solder
Circuit board epoxy resins and solder flux residues can emit volatile organic compounds (VOCs) in very small amounts during manufacturing and initial use. No health hazard has been documented for this model. VOC emissions decline sharply after the first few days of use and are negligible if the charger is used in well-ventilated spaces.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
