What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
other is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
PFAS
Unspecified waterproof finish on plastic housing likely contains PFAS-based chemistry; no test data available, but this is the industry norm for water-resistant consumer electronics absent explicit PFAS-free claims.
Source: ATSDR ↗Coating integrity and moisture ingress
If the waterproof coating degrades over time (through UV exposure, mechanical wear, or thermal cycling), water may penetrate and damage internal circuitry, though this is a mechanical rather than chemical hazard.
What’s reassuring
Plastic housing degradation and leaching
Polycarbonate or ABS plastics used in battery cases do not typically leach BPA or other endocrine disruptors under normal use. No recalls or toxicity reports for Juice Pack casings are documented.
Off-gassing from plastic or adhesives
No reports of volatile organic compound off-gassing or formaldehyde release from Mophie battery cases. Sealed plastic assemblies with adhesive layers pose low VOC risk under normal room conditions.
The full breakdown
What it's made of and why it matters
The Mophie Juice Pack uses a plastic housing (likely polycarbonate or ABS blend for durability) with an undisclosed waterproof or water-resistant coating. This coating is the critical unknown: waterproof finishes on consumer electronics often rely on PFAS-based chemistry to repel moisture, and Mophie has not publicly specified whether their coating is PFAS-free. The plastic shell itself poses minimal acute risk, but the coating formulation is essential to evaluate.
The brand's record and disclosure
Mophie (owned by Zagg, a subsidiary of Clarios) has not published a PFAS disclosure policy or material composition statements for this product line. No public recalls or toxicity incidents specific to Juice Pack cases are on record. The silence on waterproof coating chemistry is the primary transparency gap; responsible manufacturers now voluntarily disclose PFAS use or commit to PFAS-free alternatives.
How it compares in its category
Battery cases in this segment typically use plastic housings with waterproof coatings. Competitors vary widely in transparency: some brands (e.g., Otterbox) have begun PFAS disclosures, while others remain silent. Mophie's lack of public commitment to PFAS-free coatings places it in the middle of the category regarding environmental and health caution.
If you buy it
Store in a cool, dry place away from direct heat or prolonged sunlight to avoid accelerated plastic degradation or coating breakdown. Do not expose to harsh chemicals or abrasive cleaning; wipe gently with a damp cloth only. Replace the case if the waterproof coating visibly cracks, peels, or degrades, as this may allow moisture ingress and internal corrosion. Before purchase, contact Mophie customer service to request explicit confirmation that the waterproof coating does not contain PFAS compounds.
