No coating described, and no PFAS statement from the brand.
The product information we reviewed describes lithium battery, plastic housing, elastomer seals, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Mophie Juice Pack Apple iPhone 17 Pro Max is made of, ingredients and materials
The Mophie Juice Pack is a battery case combining a rechargeable lithium-ion cell, plastic housing (likely polycarbonate or ABS), and elastomer seals for water resistance. The lithium battery poses thermal and short-circuit risks if damaged; the plastic housing may leach BPA or other plasticizers under stress or heat, though modern phone accessories typically use BPA-free formulations. Elastomer seals are generally inert and designed for durability, not degradation into the device or food contact.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Lithium-ion battery thermal and electrical hazard
Integrated rechargeable lithium battery carries inherent risk of overheating, short-circuit, or fire if housing is cracked or seals fail. No product-specific incidents on record, but this is a known class risk for all battery cases.
Seal degradation and water ingress
Elastomer seals on battery cases are consumable components; degradation over months of use and temperature cycling can allow moisture into the battery compartment, risking short-circuit or corrosion.
Volatile organic compound (VOC) off-gassing from plastic and adhesives
Plastic casings and internal adhesives may emit low levels of VOCs (odor) during initial use, particularly if stored in warm conditions. This is typical for electronics plastics and not documented as a hazard for Mophie specifically, but sensitive users may notice odor.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Mophie does not disclose whether the polycarbonate or ABS housing is BPA-free. Modern phone cases typically use BPA-free resins, but no public statement from Mophie confirms this for the Juice Pack line.
Source, FDA ↗Heavy metals
No testing or disclosure from Mophie on colorant or additive composition. Consumer electronics generally avoid cadmium and lead, but lack of third-party certification leaves this unverified for this specific product.

The brand's record and disclosure
Mophie (owned by Zagg, now part of GN Store Nord) does not publicly disclose detailed chemical composition, PFAS use, or third-party safety certifications for this product line. No major product recalls or chemical hazard alerts have been documented for Mophie Juice Packs in standard consumer safety databases. The brand's silence on PFAS and material sourcing reflects industry norm for accessories rather than a known red flag.
How it compares in its category
Waterproof phone cases typically rely on sealed enclosures and elastomer gaskets rather than chemical coatings, placing Mophie in the lower-risk subset of the category. Battery cases specifically carry inherent lithium-ion hazards absent from purely protective cases; Mophie's certification compliance (CE, FCC) is standard. Similar products from Otterbox, Spigen, and Apple's own battery cases use comparable plastic and elastomer chemistries with comparable disclosure levels.
If you buy it
Inspect seals monthly for cracks or delamination that could allow water ingress and short-circuit the battery. Do not expose the case to temperatures above 60C (140F) for prolonged periods, as this accelerates plastic aging and battery degradation. Replace the case if seals visibly fail, cracks appear in the housing, or the battery no longer holds charge reliably. Avoid prolonged immersion beyond the rated depth (typically 1-2 meters); seals degrade faster in saltwater.
