Material
Plastic housing, lithium battery, rubber grip, unspecified water-resistant coating
Brand disclosure

Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
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
Mophie does not specify the plastic polymer or additives in the Juice Pack housing. If polycarbonate or vinyl-based, BPA or phthalate plasticizers may be present; direct skin contact (grip area) raises potential for dermal absorption during warm-weather use.
Source: FDA ↗PFAS
Unspecified water-resistant coating on the Juice Pack is a known risk factor for PFAS content. No Mophie statement confirms or denies PFAS use; industry standard water-repellents often contain short- or long-chain PFAS, particularly on rubber or textured surfaces.
Source: ATSDR ↗Lithium battery thermal runaway and electrolyte leakage
While the Juice Pack has no known recalls, lithium-ion cells can degrade under heat, physical stress, or manufacturing defect, potentially leaking corrosive electrolyte. Risk is low but increases with age and repeated charge cycles over 2 to 3 years.
Contact dermatitis from coating or grip material
Prolonged skin contact with unspecified rubber or plastic additives (accelerators, UV stabilizers) can trigger contact dermatitis in sensitive users. Risk is individual-dependent and would be highest in sweaty conditions or with pre-existing sensitivities.
What’s reassuring
Rubber grip degradation and off-gassing
The rubber grip material is unspecified; some rubber compounds off-gas volatile organic compounds (VOCs) or contain allergens. No specific degradation or off-gassing complaints are on record for the Juice Pack, but material transparency would help assess this.
The full breakdown
What it's made of and why it matters
The Juice Pack uses plastic housing (material type unspecified by Mophie), a lithium-ion battery, rubber grip, and an unnamed water-resistant coating. The plastic housing is the primary contact surface with your phone and hands; without material specification (e.g., ABS, polycarbonate), we cannot rule out BPA or phthalate plasticizers. The water-resistant coating is the key concern: modern water-resistance often relies on PFAS (PFAS "forever chemicals") for durability, and Mophie provides no disclosure of what their coating contains.
The brand's record and disclosure
Mophie (owned by Zagg, now part of GPMHC) has not published PFAS ingredient disclosures or material safety documentation for the Juice Pack line. No major product recalls or chemical safety incidents are on public record for this specific model. The brand does not appear in major sustainability or transparency initiatives (e.g., BEUC chemical disclosures, Science-Based Targets for PFAS reduction), suggesting limited voluntary safety communication to consumers.
How it compares in its category
iPhone battery cases are typically plastic-housing devices with lithium cells and water-resistance coatings. Apple's official MagSafe battery uses proprietary materials with no public PFAS disclosure either, placing Mophie in the typical transparency tier. Third-party brands like Anker publish somewhat more material detail, though PFAS coatings remain industry-wide. The Juice Pack is mid-market; alternatives do not offer significantly better chemical transparency at this price point.
If you buy it
Keep the case away from sustained heat above 60 degrees Celsius (140F), as lithium batteries degrade faster and plastic may off-gas at elevated temperatures. Wipe the exterior monthly with a dry cloth to minimize skin contact with any coating residues. Replace the battery case every 2 to 3 years if it sees regular use; lithium cells lose capacity and housing can crack, risking chemical leakage. Avoid dropping or exposing to high humidity for extended periods; this stresses the water-resistant coating and can cause internal corrosion.
