mophie Juice Pack Air Battery Case for iPXS Max
Skip; waterproof battery case likely uses PFAS-based water repellents.
Mophie does not disclose PFAS use or absence. Battery cases typically employ water-resistant coatings that often contain PFAS. No third-party verification available.

The full breakdown
What it's made of and why it matters
The Juice Pack Air is a rigid plastic housing (likely polycarbonate or ABS) with integrated lithium-ion battery cells, rubber grip accents, and unspecified protective coatings. The waterproof design almost certainly uses fluorochemical water repellents (PFAS or PFAS-like compounds) to seal the charging port and seams, a standard industry approach for water-resistant electronics. No public material safety data sheet or detailed composition disclosure is available from Mophie for the rubber or coating compounds, which limits full hazard characterization.
The brand's record and disclosure
Mophie (owned by Zagg Inc., now Zagg Inc./Zagg Ventures) does not publish specific material composition data or PFAS avoidance commitments in its consumer communications. The company has no known formal environmental certifications (e.g., iFixit repairability score, Declare labels, or EPEAT listing) for this product line. No safety recalls or heavy-metal contamination incidents are on record for Juice Pack Air variants, though the brand has faced typical lithium battery expansion complaints in older model reviews on retail sites.
How it compares in its category
Battery cases in this segment (e.g., Apple Smart Battery Case, Anker) share identical water-repellent coating and lithium chemistry risks; Mophie's lack of transparency is slightly worse than competitors offering recycling programs or material disclosures. The Juice Pack Air's sealed design reduces user exposure to internal components compared to modular cases, lowering direct contact hazards. However, the integrated battery makes replacement difficult and extends e-waste risk if the product fails before the iPhone itself needs replacement.
If you buy it
Do not charge if you notice any bulging, heat beyond normal warmth, or visible coating cracks, as lithium cells can vent or catch fire when degraded. Keep away from heat sources and high humidity; store at room temperature with 40-60% battery charge if not in use for months. Inspect the charging port seal yearly for wear and do not attempt to open or repair the battery yourself. Recycle through an e-waste program rather than trash; Mophie does not operate a take-back scheme, so contact local hazardous electronics recycling centers.
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.”
Lithium battery thermal runaway / expansion
Integrated Li-ion cells degrade over 2-3 years of charge cycles; physical damage or manufacturing defects can cause bulging or thermal failure. No independent testing results for this specific model are published; user complaints in online reviews mention slow charging and warmth after 18+ months.
Coating degradation and leachables from unspecified rubber/plastic treatments
Rubber grip accents and protective coatings lack public composition data; wear and microcracking over time may release unidentified additives. Mophie provides no guidance on safe lifespan or coating safety.
Fluorochemical (PFAS or PFAS-like) water-repellent coatings
Waterproof battery cases universally rely on fluorochemical water repellents applied to housing seams and the charging port. These compounds accumulate in the body and environment; no alternative is standard in consumer electronics yet. (See separate PFAS assessment for full risk grade.)
Plastic housing off-gassing (polycarbonate/ABS)
Rigid engineered plastics in sealed casings do not typically off-gas significantly at room temperature; no reports of chemical odor complaints specific to this product. Risk is minimal under normal storage and use.
Heavy metals in pigments or solder joints
No cadmium, lead, or mercury contamination has been documented in Juice Pack Air teardowns or testing. Lithium battery internal solder and contacts are standard for the industry and do not pose exposure risk in a sealed case.
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.
