Material
Plastic housing, synthetic polymer battery casing, unspecified coatings
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.
BPA & bisphenols
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.
Source: FDA ↗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.
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.
What’s reassuring
Flame retardants
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.
Source: EPA ↗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.
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.
