The full breakdown
What it's made of and why it matters
The Mophie Juice Pack Access uses a hardshell polycarbonate or ABS plastic casing around an internal lithium-ion battery. These rigid plastics are chosen for durability and impact protection rather than flexibility. The material itself is relatively stable during normal use, but the real concern is what chemical additives (including potential PFAS water-repellents or flame retardants) may be present in the formulation, which Mophie has not publicly disclosed.
The brand's record and disclosure
Mophie (owned by ZAGG Inc., now part of GN Store Nord) has not published material safety data sheets, chemical composition disclosures, or commitments to phasing out problematic additives in battery cases. The brand remains silent on PFAS use despite growing industry scrutiny. No major safety recalls have been issued for this specific model, but the lack of transparency is notable in a category where battery cases receive sustained contact with skin and pockets.
How it compares in its category
Battery case hazards typically center on battery thermal runaway, plastic leaching, and additive migration during heat or sweat exposure. Mophie cases are mid-tier for durability but lag behind brands like Anker that provide material transparency certifications. Many competitors remain equally opaque on chemistry, making this a category-wide disclosure gap rather than a Mophie-specific failure.
If you buy it
Avoid prolonged direct skin contact by using the case as designed (on the phone, not held bare). Do not expose to sustained heat above 50C (122F); battery cases generate warmth during charging and heavy use, so monitor temperature. Replace the case if the plastic shows cracking, discoloration, or warping, as this may allow internal battery electrolyte contact. Clean periodically with a dry cloth; avoid extended moisture exposure that could compromise the seal.
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.”
Plastic additives (flame retardants, plasticizers, water repellents) with unknown composit
Hardshell plastics in consumer electronics often contain brominated flame retardants, antimony compounds, or PFAS-based water repellents. Mophie discloses none of these; skin contact and heat exposure could increase migration risk, especially during summer or heavy charging cycles.
Lithium-ion battery thermal hazard and electrolyte leakage
Microplastics from degradation during device lifetime
Hardshell plastics can fragment under repeated bending, drops, or UV exposure over 2-3 years of daily use. The Juice Pack Access, while more durable than soft silicone, is not immune; users may inadvertently shed microplastics into pockets, bags, or soil.
Volatile organic compounds (VOC) off-gassing during manufacturing and early use
No independent testing or recalls document off-gassing from this specific case. Hardshell polycarbonate/ABS typically off-gasses minimally compared to softer polymers, but unaired new cases may release trace solvents for 24-48 hours.
Heavy metals in printed logos or labeling
The case features printed branding and possibly colored trim. No public data exists on ink composition for Mophie cases, but lead and cadmium in industrial printing inks are still possible in unregulated supply chains, though unlikely for a major brand.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
