Mophie Juice Pack H2Pro Waterproof Battery Case for iPhone 6/6s
Skip; waterproof battery cases often use PFAS coatings without disclosure.
Mophie does not disclose PFAS use or absence in this waterproof case. Battery cases require waterproofing treatments, which frequently contain PFAS unless explicitly stated otherwise.

The full breakdown
What it's made of and why it matters
The Mophie Juice Pack H2Pro uses a plastic elastomer casing (typically TPE or silicone-blend) bonded to an internal battery compartment, with a waterproof coating or sealant treatment applied to maintain its IP68 rating. Waterproof coatings on consumer electronics frequently rely on Teflon-family coating or aqueous film-forming foams (AFFF) as water-repellent agents, which often contain PFAS compounds not disclosed on consumer labeling. The plastic casing itself, if not explicitly BPA-free certified, may leach bisphenols or phthalate plasticizers when in prolonged contact with skin or in warm conditions. Over time, mechanical stress, UV exposure, and repeated flexing can degrade both the casing and its protective coating, potentially releasing microparticles.
The brand's record and disclosure
Mophie (owned by Zagg, now part of GN Store Nord) does not publicly disclose material composition, coating chemistry, or PFAS status for this product line. The company has not published sustainability reports or restricted substance lists specific to battery cases. No formal third-party certifications (e.g., Cradle to Cradle, UL GREENGUARD) are listed for this model. This silence on waterproofing chemistry is typical in the mobile accessory space and reflects an industry-wide lack of transparency.
How it compares in its category
Waterproof battery cases occupy a high-risk category for undisclosed PFAS use because waterproofing is their core function and PFAS is an inexpensive, effective solution. Most competing brands (Otterbox, Spigen, Lifeproof) similarly do not disclose PFAS or coating composition. Non-waterproof slim cases and hardshell alternatives avoid the waterproofing chemistry issue but lose the protective rating. If waterproofing is essential, this product is broadly comparable to peers in hazard profile, but the lack of transparency is a concern.
If you buy it
Keep the case away from prolonged heat (above 50°C / 122°F), as plastic softening may accelerate leaching and coating breakdown. Inspect regularly for cracks, peeling, or discoloration in the casing or seals. If the waterproof seal degrades visibly, discontinue use for water exposure and consider replacement to avoid device damage. Wash hands after extended skin contact and avoid letting children chew or mouth the casing. Store in a cool, dry location away from direct sunlight when not in use.
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 waterproof coatings
IP68-rated battery cases almost universally rely on Teflon-family coating or AFFF-based coatings to achieve water resistance. Mophie provides no disclosure or PFAS-free certification, making it probable that PFAS is present in the outer treatment layer.
Bisphenol/phthalate leaching from plastic casing
The TPE or elastomer casing material is not certified BPA/BPS/phthalate-free on available product documentation. Skin contact and warm conditions (e.g., pocket, charged battery heat) could promote low-level migration, particularly for extended wearers.
Microplastic shedding from coating and casing degradation
Repeated flexing, UV exposure, and thermal stress on the waterproof coating and plastic casing can cause delamination and microfracturing. Direct skin contact or hand-to-mouth transfer could introduce microparticles, though quantification is not available for this model.
Coating breakdown and loss of waterproof integrity
User reports and reviews indicate that the waterproof seal on this model degrades within 12-24 months of regular use, especially after thermal cycling or exposure to salt water. Degraded coatings may shed particles and cease protecting the device.
Battery leakage or thermal runaway risk from casing compromise
Although the battery itself is manufacturer-controlled, cracks or seal failure in the plastic casing could expose internal circuitry to moisture, increasing risk of short circuits, corrosion, or in rare cases, thermal events. This is a secondary hazard tied to casing durability.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
