The full breakdown
What it's made of and why it matters
The Mophie Juice Pack Case uses thermoplastic elastomer (TPE) as its primary shell material, a flexible synthetic polymer that resists cracking and provides grip. TPE itself is considered low-toxicity compared to PVC, but Mophie applies a water-resistant coating to meet the case's IP-rated durability claims. This coating is the unknown variable: water-resistant treatments on consumer electronics often rely on fluorinated compounds (PFAS-based) or silicone-based alternatives, and Mophie provides no public documentation of which.
The brand's record and disclosure
Mophie (owned by Zagg/ZAGG Inc., now part of GN Store Nord) has not published material safety data sheets or PFAS-avoidance commitments for its phone cases. The brand does not appear on transparency registries for chemical disclosure or on major PFAS-free certifications. Mophie's website emphasizes durability and design but omits ingredient transparency. This silence is not unusual for the accessory category but represents a gap versus competitors who have begun public PFAS disclosure.
How it compares in its category
Battery cases occupy a niche between protective sleeves and integrated charging devices, making them subject to durability claims that drive coating use. Competitors like Spigen and OtterBox have similarly undisclosed coating compositions. Few brands in this category (protective cases with integrated electronics) publish PFAS inventories; Mophie is neither ahead nor behind peer transparency. The case's main differentiator is battery integration rather than material safety, making it typical for its market segment.
If you buy it
Store the case away from direct heat sources and extreme humidity when not in use; water-resistant coatings can degrade faster under thermal stress. Inspect the case every 6-12 months for peeling, cracking, or clouding of the coating, which signals loss of protective function and potential leaching of coating components. If the coating visibly degrades, discontinue use rather than repair it with adhesives. Avoid prolonged contact between the case interior and bare skin or food-contact items while the coating integrity is unknown.
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.”
Water-resistant coating leachables (non-PFAS)
Mophie has not disclosed the chemistry of its water-resistant treatment. If silicone-based, leaching risk is low; if fluorocarbon-based but non-PFAS, risk remains unclear. Degraded or damaged coatings pose higher leaching exposure to skin and sweat.
TPE polymer off-gassing or migration
TPE is generally considered chemically stable and low-volatility. No public recalls or toxicity reports for Mophie cases specifically. Risk increases if the case is heated (e.g., in a hot car) and comes into contact with skin for hours daily.
Coating degradation and particulate shedding
Water-resistant coatings on elastomers can chip, peel, or flake with wear, particularly at high-stress seams or corners. Inhalation or ingestion of shed coating particles is unlikely during normal use but possible if the case is handled roughly or stored in warm, humid conditions.
Battery and electronic component safety (adjacent to material hazard)
Mophie's battery units have had no major recalls in recent years, but the case's insulating properties depend on coating integrity. Failure of the water-resistant coating could theoretically expose battery components to moisture, a fire or injury risk.
Allergen potential from coating or plasticizers
TPE formulations can include various plasticizers and colorants, but Mophie has not disclosed these. Individuals with sensitivities to synthetic polymers or coatings should patch-test by wearing the case for short periods first.
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.
