Material
Polymer/plastic battery casing with waterproof coating
Brand disclosure
Brand is silent on PFAS
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.
PFAS
Mophie has not disclosed the chemical nature of its waterproof treatment. Industry standard for sealed electronics is Teflon-family coating coatings, which often contain PFAS; however, absence of disclosure does not confirm presence. This is the primary uncertainty in the safety profile.
Source: ATSDR ↗Lithium-ion battery thermal runaway (general product hazard, not material-specific)
External battery packs carry standard lithium-ion fire/burn risk if damaged, overcharged, or used with faulty cables. Mophie packs have no documented recall history for thermal events, indicating standard safety engineering, but this remains an inherent hazard of the product category.
What’s reassuring
Polymer off-gassing (volatile organic compounds)
Plastic battery casings may emit trace VOCs (formaldehyde, toluene) during manufacturing and early use, but no reported issues specific to Mophie Juice Pack models. Risk is low with normal ventilation and storage conditions.
Microplastic shedding from polymer degradation
Polymer case may degrade over years of use, but external battery packs do not contact food or drinking water, so ingestion risk is minimal. Shedding into the environment is possible if discarded improperly.
Heavy metals
Modern battery pack manufacturers generally comply with RoHS (Restriction of Hazardous Substances) for lead and cadmium in solder. No specific testing data for Mophie is public, but major recalls for this hazard in this product category are rare.

What it's made of and why it matters
The Mophie Juice Pack uses a polymer (plastic) outer casing with an internal lithium-ion battery and a waterproof coating layer. The waterproof treatment composition is not publicly disclosed by Mophie, which is the main concern: waterproof coatings on consumer electronics historically use PFAS compounds (PFAS "forever chemicals") to repel water, though some manufacturers have begun switching to PFAS-free alternatives. The polymer casing itself is unlikely to leach BPA or phthalates under normal use, but the undisclosed coating is the opacity point.
The brand's record and disclosure
Mophie (owned by Zagg, itself owned by AAOS) does not publish material safety data sheets or PFAS-free certification for its battery accessories. The company has not released public statements on PFAS elimination in its product lines. No major product recalls for chemical contamination or battery hazards specific to this model are documented in FDA or CPSC records as of available information. This silence on material composition is standard for the mobile accessory market but represents a gap in transparency.
How it compares in its category
External battery packs (power banks) are a high-volume consumer category with mixed material disclosure practices. Most competitors (Anker, Belkin, Samsung) similarly do not disclose waterproof coating chemistry, making this product typical rather than exceptional. A small number of brands (e.g., some solar chargers) advertise PFAS-free coatings, but none dominate the iPhone accessory space. Mophie is mid-range in transparency for this category.
If you buy it
Avoid exposing the device to prolonged heat (do not leave in direct sunlight for hours) as polymer softening can stress the battery compartment seals. Clean only with dry cloths; avoid soaking or harsh scrubbing, which could degrade the waterproof coating and increase leaching risk if coating is compromised. Replace the unit if the casing shows visible cracks, peeling, or discoloration, which signal coating breakdown. Store in a cool, dry place when not in use to extend lifespan and minimize off-gassing from the plastic matrix.
