The full breakdown
What it's made of and why it matters
The Mophie Juice Pack uses plastic housing (type unspecified by manufacturer) surrounding a lithium-ion battery pack with synthetic polymer casing. The lack of public material specification means you cannot verify whether the plastics are polycarbonate, ABS, or other polymers, or whether coatings contain additives like BPA, phthalates, or flame retardants. This opacity is the core transparency issue: most premium battery cases disclose resin type, but Mophie does not.
The brand's record and disclosure
Mophie (owned by Zagg/ZAGG Ventures) has not published material safety data sheets or restricted substance lists for this product line. No public PFAS disclosure or commitment to PFAS reduction is available. The company has no known safety certifications (RoHS, REACH compliance statements) highlighted in marketing or regulatory filings for consumer battery accessories. This silence contrasts with competitors like Anker and Belkin, who provide material transparency.
How it compares in its category
Battery cases sit in a lower-hazard tier than cookware or cosmetics because plastic housing has minimal skin contact and internal chemistry is sealed. However, Mophie ranks below transparent competitors: Anker Nano discloses ABS plastic; OtterBox states polycarbonate use. The Juice Pack's lack of specification is a relative weakness in an otherwise safe product category, making informed comparison impossible.
If you buy it
Avoid exposing the case to direct sunlight for extended periods or temperatures above 45C (113F), as polymer degradation may release trace additives. Do not drop or puncture the case; physical damage to the battery compartment or housing can lead to electrolyte leakage or accelerated plastic off-gassing. Replace the case if cracking or discoloration develops. Clean only with dry microfiber cloth; avoid solvents that may leach coatings.
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.”
BPA or phthalates in plastic housing
Unspecified plastic resin makes it impossible to rule out BPA-containing polycarbonate or phthalate plasticizers. Contact with skin (hands, face) is intermittent but regular. No manufacturer statement excludes these additives.
Polymer degradation and leachate release
Lithium-ion batteries generate heat during charging. Over 1-2 years, repeated thermal stress on plastic casing may degrade polymers and release trace monomers or additives. Risk is low under normal use but increases if case is dropped or exposed to heat.
Flame retardants in plastic or battery casing
Battery accessories may use flame-retardant additives (brominated or phosphate-based) to meet UL or safety standards. Mophie has not disclosed whether flame retardants are present. Contact exposure is minimal; internal risk is low unless case ruptures.
Battery leakage and chemical exposure risk
If internal lithium-ion battery is damaged by drop, puncture, or pressure, electrolyte (organic solvent) and lithium salts can leak into plastic seams and onto skin. This is a physical integrity hazard, not a material hazard, but underscores the value of protective case design transparency.
Off-gassing of volatile organic compounds (VOCs) from coatings or adhesives
Plastic cases may use adhesives or surface coatings containing VOCs or formaldehyde. No public data on Mophie's manufacturing specifications. Risk is minimal for sealed plastic electronics but increases if case is heated or damaged.
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.
