Mophie Juice Pack Battery Case for iPhone 16 Pro Max
Skip until waterproofing materials disclosed by Mophie.
Battery cases typically use coatings for water resistance and durability. Mophie does not publicly disclose waterproofing chemistry or PFAS status for this product, creating moderate uncertainty.

The full breakdown
What it's made of and why it matters
The Mophie Juice Pack uses silicone and TPE (thermoplastic elastomer) as primary materials, which are generally stable and do not leach BPA or phthalates under normal conditions. The case encases a lithium-ion battery pack with unknown protective or waterproofing coatings applied to seams and connectors. These coatings are the primary concern: manufacturers often use PFAS-based water repellents on textiles and elastomers to achieve water resistance, though Mophie has not disclosed what is used here.
The brand's record and disclosure
Mophie (owned by Zagg/Incipio Group) has not published a PFAS disclosure policy or chemical safety transparency report in public databases searched by consumer advocacy groups. The brand does not list materials or coating compounds on product pages or safety documentation. This silence on chemical composition is the primary issue; competitors like Anker and Belkin have begun to address PFAS use in accessories, but Mophie has not engaged visibly on this topic.
How it compares in its category
Battery cases are a high-contact product category where waterproofing is standard. Most major brands use silicone or TPE bodies, but differ widely in coating transparency. Mophie's lack of disclosure places it in the middle-to-lower range for transparency compared to brands with published restricted substance lists. Cases using hard plastics (polycarbonate) instead of coated elastomers may reduce PFAS risk, though they trade off durability and comfort.
If you buy it
Do not expose the case to temperatures above 60°C (140°F) as silicone and TPE can degrade and release compounds at higher heat, and battery stress may accelerate coating breakdown. Avoid prolonged contact with oils, solvents, or strong detergents that can weaken seams and coatings. Replace the case if you notice visible cracking, peeling, or separation at seams, as this signals failure of the protective barrier. Clean with lukewarm water and mild soap only; air dry thoroughly before charging.
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.”
PFAS in waterproofing coatings
Undisclosed coatings on seams and connector ports likely contain water-repellent compounds; PFAS presence is standard in elastomer treatments, but Mophie provides no verification or alternatives. Water contact during use or cleaning could mobilize trace PFAS into skin or household water.
Silicone and TPE degradation over time
Silicone cases are documented to yellow, harden, and crack after 12-24 months of use, especially in heat or sunlight. Degradation can expose the underlying lithium-ion battery casing and breach the water resistance seal, increasing risk of leakage or short circuits.
Lithium-ion battery thermal runaway or leakage
If the protective case is punctured or seals fail, the battery can overheat or leak electrolyte fluid. This is a rare but documented risk in damaged battery cases; electrolyte can irritate skin and eyes.
Microplastics from case wear
Silicone and TPE shed microscopic particles as they degrade from friction, thermal cycling, and UV exposure. These particles are not captured by the case design and may contaminate skin or the charging port area over time, though systemic exposure via hand contact is likely minimal.
Heavy metals in battery connector coatings
No recalls or test reports document lead, cadmium, or nickel in Mophie case battery contacts. Standard gold or nickel plating is typical and does not pose acute risk with normal handling, but connector degradation could theoretically increase contact; no evidence of this in the field.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 40% 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.
