Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
other is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
This power bank uses a polymer (likely polycarbonate or ABS) housing with an unspecified waterproof coating. The coating's chemical composition is the critical unknown: waterproof treatments commonly use Teflon-family coating, polyurethane, or silicone-based compounds, some of which may contain PFAS or other leachable additives. Without manufacturer disclosure of the coating type, you cannot assess whether chemicals migrate into food or skin contact scenarios, though risk is low for brief handling of a power bank itself.
The brand's record and disclosure
Waterproof Co. has not publicly disclosed the specific chemistry of its waterproof coatings, PFAS content, or manufacturing certifications. No established safety recalls or third-party testing results for this model are on record. The brand's silence on fluorochemical use is typical of smaller electronics manufacturers but prevents independent verification of claims. Purchase of this product amounts to trust in the brand's quality control without transparent chemical accountability.
How it compares in its category
Rugged power banks vary widely in waterproof approach: some use mechanical seals and gaskets (transparent, lower chemical risk), while others rely on protective coatings (hidden chemical risk). Higher-end brands like Anker and Goal Zero typically disclose coating materials and hold IP certifications that indirectly confirm seal integrity. This Techsmarter model sits in the mid-market segment where coating chemistry is rarely disclosed, making it harder to verify durability or leachable content compared to premium alternatives.
If you buy it
Keep the power bank away from prolonged skin contact with the coating (brief handling is safe). Do not submerge it unless manufacturer explicitly states full waterproofing; waterproof coatings can degrade over time, and exposure accelerates this. Inspect the housing monthly for cracks, peeling, or discoloration that signals coating breakdown. If the coating chips or flakes, discontinue use to prevent potential leaching of the coating material, and contact the manufacturer for replacement.
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 degradation and leaching
Unknown coating type means unknown durability and leachable compounds. Mechanical stress, UV exposure, and thermal cycling can degrade Teflon-family coating or polyurethane coatings, potentially releasing monomers or additives; risk is low during normal use but increases if coating is damaged.
Electrical safety (battery/circuitry)
No specific safety incidents recorded for this model. Standard lithium-ion power banks carry general risk of thermal runaway if damaged or defective, but this is not unique to this brand and applies to the category; purchase from sellers with return policies to mitigate defective unit risk.
Polymer off-gassing or odor
Polymer housings (ABS/polycarbonate) and waterproof coatings may emit volatile organic compounds (VOCs) when new; typically dissipates within days to weeks. Not a health hazard for brief handling but may indicate lower manufacturing standards if smell is strong or persistent.
Heavy metals in coating pigments or additives
No published testing or recall data available for this product. Risk is low because waterproof coatings are topical and not ingested, but absence of testing data means heavy metal content (e.g., lead, cadmium stabilizers) cannot be ruled out by available information.
Undisclosed PFAS in waterproof treatment
Waterproof coatings frequently rely on fluorinated compounds; brand silence on this chemistry suggests either PFAS use without disclosure or deliberate opacity. This hazard is graded separately in PFAS assessment but contributes to overall recommendation of caution.
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.
