What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Water-resistant coating composition (unknown)
Unspecified coating formulation typical of this category may contain Teflon-family coating, some of which include PFAS. Without disclosure or third-party testing, actual risk cannot be quantified from available public information.
Plastic off-gassing (VOC/volatile organics)
Polycarbonate and TPE blends used in phone cases can emit low levels of volatile organic compounds, especially when heated. Risk is minimal under normal room-temperature use but increases with heat exposure or prolonged storage in hot vehicles.
Coating degradation and leaching over time
Water-resistant coatings degrade with physical wear and UV exposure. As the coating flakes or peels, the underlying plastic base and any residual coating chemicals may contact skin or food surfaces, though absolute risk remains unquantified.
Microplastic shedding from worn case
Extended use, flexing, and impacts can cause microscopic plastic particles to shed from the case surface. Risk is low for skin contact but possible if case fragments enter food or water handled by user.
Brand transparency and consumer accountability
Mophie's silence on material safety and PFAS use is a documented industry pattern; this is not a product-specific failure but a category-wide transparency gap that complicates informed choice.
The full breakdown
What it's made of and why it matters
Mophie Juice Pack cases are constructed from plastic housing, likely polycarbonate or TPE blend for shock absorption, with an unspecified water-resistant surface coating. The coating formulation is not publicly disclosed by Mophie, which is the primary concern here since water-resistant coatings on consumer electronics frequently rely on Teflon-family coating technologies that may contain PFAS. Without transparency on coating chemistry, the actual composition and leaching risk cannot be assessed from available information.
The brand's record and disclosure
Mophie (owned by Zagg Inc.) maintains minimal public disclosure on material composition, chemical hazards, or PFAS use across its product lines. The company has not published supply-chain safety reports, PFAS phase-out commitments, or third-party safety certifications for this case model. This silence is notable in an industry where some competitors (e.g., Spigen, Otterbox) have begun voluntary transparency initiatives on coating chemicals.
How it compares in its category
Battery cases are a niche category where water-resistant coatings are nearly universal, making this case typical rather than exceptional in its opacity. Competitors range from similarly non-transparent mid-tier brands to premium cases (Otterbox) with published material safety data. The Juice Pack competes on charging capacity and form factor, not material safety messaging, which reflects lower-tier transparency standards within the category.
If you buy it
Avoid prolonged contact with hot surfaces or direct sunlight exposure, as plastic housings can off-gas volatile compounds when heated. Do not immerse the case in hot water or place it on heated charging surfaces; room-temperature water exposure for cleaning is acceptable. Replace the case if the plastic shows visible cracking, clouding, or peeling of the coating, as degradation may increase leaching risk. Store in a cool, dry place away from direct heat sources and solvents.
