mophie Juice Pack Case for Apple iPhone 17 Pro
Wait for mophie to reveal coating details and PFAS information.
Mophie keeps PFAS details about this battery case confidential. The waterproof coating is unidentified, creating uncertainty about potential PFAS content.

Material
Polymer case with unspecified waterproof/protective coatings
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
PFAS
Waterproof protective coatings on polymer cases frequently contain PFAS or other fluorinated compounds; mophie does not publicly disclose coating identity, leaving PFAS exposure status uncertain.
Source: ATSDR ↗Microplastic shedding from coating degradation
As the case ages and the protective coating breaks down, small polymer particles and coating fragments may leach into skin contact areas or the device. No testing data available for this specific product.
Volatile organic compound (VOC) off-gassing from polymer base and coatings
TPU/TPE blends and applied surface coatings can emit VOCs, particularly under heat or sunlight. Mophie has not published off-gas testing results for this case.
Bacterial or mold growth in seal crevices
Tight-sealing waterproof cases can trap moisture in edge seams if not dried promptly after water exposure, creating conditions for microbial growth in crevices.
What’s reassuring
Heavy metals
No reports of heavy metal contamination in mophie cases, but pigments in protective coatings are not independently verified and could contain cadmium or lead in low-cost formulations.

What it's made of and why it matters
Mophie Juice Pack cases are polymer-based (typically TPU or TPE elastomer blended with rigid polycarbonate) designed for shock absorption and water resistance. The waterproof capability comes from unspecified surface coatings or sealant layers applied to the polymer base, which are not publicly itemized by the brand. Without disclosure of coating chemistry, you cannot verify whether these layers contain PFAS, phthalates, or other problematic additives used to enhance water repellency and durability.
The brand's record and disclosure
Mophie (owned by Zagg Inc., now part of GN Store Nord) has not published detailed material safety data or environmental health statements for its case product lines. The brand does not maintain a public PFAS disclosure policy or third-party material certifications (such as Cradle to Cradle or bluesign) for polymer accessories. No significant recalls or hazard reports are on record for this specific product line, but the absence of transparency on coating composition is a material gap in safety assurance.
How it compares in its category
Protective phone cases typically use TPU/TPE polymer bases, but brands vary widely in coating transparency. Some competitors (e.g., Pela, made from plant-based biopolymer) publish material sourcing; others remain opaque. Mophie's waterproof claim without ingredient disclosure is common in the mid-market accessory space but falls short of industry best practice, which now favors PFAS-free water-resistant treatments or explicit non-PFAS certification.
If you buy it
Inspect the case regularly for cracking, peeling, or discoloration of the coating, which signals potential microplastic shedding or coating breakdown. Avoid prolonged exposure to direct sunlight or heat above 50°C (122°F), as polymer-based cases can off-gas volatile compounds if degraded. Do not assume water resistance is permanent; test the seal periodically, especially if the case shows wear. Consider replacement if the coating visibly deteriorates or if the case develops an odor, which may indicate polymer degradation.
