Nuxkst Premium USB Charger Charging Cable for Mophie Juice Pack Air Plus
Low risk. Standard USB cable with no known PFAS concern.
USB charging cables use PVC or TPE insulation without intentional PFAS. Cable materials are not typical PFAS application areas.

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.
PVC thermal degradation and plasticizer migration
If the cable uses PVC, prolonged exposure to heat (>60°C) can soften the insulation and may release trace plasticizers (typically diisononyl phthalate or DINP). Normal USB charging generates minimal heat at the cable sheath, but coiled storage or proximity to heat sources increases risk. TPE variants eliminate this concern entirely.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Electrical safety and insulation failure
No recalls or reported failures of this specific cable exist. Standard USB cables for Mophie Juice Pack products are manufactured to meet UL and FCC electrical safety standards. Risk of shock or fire is extremely low under normal use and storage.
Copper conductor corrosion and contact degradation
The internal copper conductors are shielded by insulation and connectors. No documented cases of corrosion-induced failure or contamination from this cable type exist. Moisture exposure or salt spray (not typical for indoor charging) would be the only realistic concern.
Connector material leaching (brass, nickel)
USB connectors are typically brass or copper-plated steel with nickel. No skin contact hazard exists in normal use. Nickel sensitivity is not triggered by contact with the outside of a connector; internal conductor exposure only occurs if the cable is damaged and stripped bare.
Microplastic shedding from cable insulation
PVC and TPE do not shed microplastics under normal use conditions. Visible disintegration would require advanced degradation (UV, high heat, or mechanical abrasion) not typical of stored or gently used charging cables.
The full breakdown
What it's made of and why it matters
This is a standard USB charging cable using either PVC (polyvinyl chloride) or TPE (thermoplastic elastomer) insulation around copper conductors. PVC is rigid and cost-effective but can degrade with heat; TPE is more flexible and heat-resistant, making it preferable for frequent use. Both materials are chemically stable under normal charging conditions (low voltage, room temperature) and pose minimal leaching risk to skin contact or in the intended use environment. The cable interior is copper, which does not leach under these low-stress conditions.
The brand's record and disclosure
Mophie (owned by Zagg Inc.) manufactures widely used mobile charging accessories and has no public safety recalls or hazard warnings on record for USB cables. The brand does not advertise specific material certifications (RoHS, phthalate-free, etc.) in standard marketing, though third-party testing typically confirms compliance with FCC and basic electrical safety standards for consumer USB peripherals. No documented controversies regarding material toxicity or manufacturing disclosures exist for this product line.
How it compares in its category
USB charging cables are a commodity category with minimal differentiation in safety profile. This Mophie cable sits in the mainstream tier, better build quality and durability than ultra-cheap alternatives, comparable safety to Apple or Samsung OEM cables, and likely superior to counterfeit or heavily discounted unbranded knockoffs. All legitimate USB cables sold in major channels (Amazon, Mophie direct, retail) meet baseline electrical safety standards; the main variable is longevity rather than acute hazard.
If you buy it
Store the cable at room temperature away from direct sunlight and extreme heat (do not leave in cars or near radiators, as PVC can soften above 70 degrees C). Inspect regularly for visible cracks, exposed wiring, or discoloration; replace immediately if damage occurs, as a compromised cable poses electrical risk. Do not wrap tightly around chargers or devices immediately after use if warm; allow cooling first to avoid insulation fatigue. Standard lifespan is 1-3 years depending on flex frequency; replacement is inexpensive and recommended proactively if the cable is bent repeatedly or shows stiffness.
