Material
Hardshell plastic casing, internal battery
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Unknown / proprietary coating
Has a special coating but the exact formula is secret.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Flame retardants
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.

Microplastics
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.
Source: EPA ↗What’s reassuring
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
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 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.
