Mophie Juice Pack Battery Case for iPhone 15 Pro
Lower concern. Battery cases lack typical PFAS-prone coatings; no public disclosure available.
Mophie Juice Pack is a battery case with lithium-ion cells and plastic housing. No waterproofing or stain-resistant treatments reported, reducing typical PFAS contamination pathways in consumer electronics.

The full breakdown
What it's made of and why it matters
The Mophie Juice Pack houses a lithium-ion battery cell with a plastic (likely polycarbonate or ABS) exterior housing and rubber grip surfaces. This material combination is standard in portable power products and avoids the problematic coatings (Teflon-type coating, epoxy resins, water-repellent treatments) that trap PFAS in cookware or textiles. The main chemical exposure pathways are minimal since the battery is sealed and plastic contact with skin or food is negligible.
The brand's record and disclosure
Mophie (owned by Zagg/Zagg Inc., now part of GN Store Nord) does not publicly disclose material safety data, PFAS use, or third-party certifications for battery cases. No major recalls or chemical safety controversies have been documented for this product line. The brand's opacity on chemical disclosure is typical of the mobile accessory industry but prevents verification of manufacturing claims.
How it compares in its category
Battery cases rank low-risk compared to cookware, cosmetics, or flame-retardant textiles because they avoid high-temperature cooking, skin absorption, and regulatory pressure for flame resistance. Competitors like Anker and Belkin operate similarly without enhanced transparency. The main differentiator across brands is build quality and battery cycle life, not chemical composition.
If you buy it
Keep the case away from direct heat (above 40-45°C / 104-113°F continuous exposure) to preserve the lithium-ion cell lifespan and prevent plastic off-gassing. Do not expose to water or humidity without the sealed design intact; corrosion can trigger short circuits. Replace the case if plastic cracks, the battery puffs, or charging becomes inconsistent, typically after 2-3 years of heavy use. Store in a cool, dry place and avoid compression under weight.
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-ion battery thermal runaway
All lithium-ion batteries carry low but non-zero risk of thermal runaway if damaged, overcharged, or exposed to extreme heat. This is not unique to Mophie but inherent to the chemistry; proper case design minimizes risk by including charge controllers and thermal cutoffs, which are standard in reputable brands.
Plastic off-gassing (volatile organic compounds from housing)
Polycarbonate and ABS plastics may emit trace VOCs during manufacturing or when heated above normal ambient temperatures. No recalls or test data specific to Mophie cases document problematic off-gassing under normal use conditions (room temperature, intermittent heat from charging).
Heavy metals in solder or internal circuitry
Battery cases contain internal circuit boards with solder and electronic components. Lead-free solder is standard in consumer electronics sold in EU and many US markets, but no third-party testing of this specific product has been publicly disclosed. Risk is minimal given sealed design and no skin contact pathway.
Rubber grip degradation and leachates
Rubber or elastomer grips may contain plasticizers or sulfur compounds that could leach with prolonged contact or when exposed to oils and sweat. No documented issues or recalls for Mophie cases; however, degraded grip material should be avoided if it becomes sticky or discolored.
Microplastic shedding from wear
Plastic housings and rubber grips can shed microparticles over time with repeated drops, compression, or friction. While the particle load is very small and not ingested (external product), accumulation in pockets or bags is possible and environmentally relevant over the product lifecycle.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
