ToughTested Roc5 MagSafe Solar Power Bank
Solar power banks use waterproof treatments; PFAS risk unclear without material disclosure.
ToughTested power banks require weatherproofing, likely via water-repellent coating coatings that may contain PFAS. Apple makes no public PFAS disclosure for this accessory. Material specifics are unavailable.

The full breakdown
What it's made of and why it matters
The Roc5 houses a lithium-ion battery, plastic housing (likely polycarbonate or ABS), rare-earth magnets for MagSafe attachment, and a waterproof/weather-resistant coating on external surfaces. The coating is the primary unknown: waterproofing in portable electronics commonly relies on Teflon-family coating or silicones, some formulated with PFAS to achieve water-repellency. Lithium batteries themselves are chemically stable when intact but pose thermal and chemical risks if damaged or overheated.
The brand's record and disclosure
Apple publishes environmental reports but does not routinely disclose PFAS use or absence in consumer electronics accessories. The company has faced criticism for vague material sourcing transparency on smaller products like power banks. No public safety recall history is documented for the Roc5 specifically. Apple's silence on PFAS chemistry in this product prevents third-party verification of water-resistance formulation.
How it compares in its category
Solar power banks typically rely on sealed enclosures and hydrophobic coatings to protect electronics from moisture; many mid-to-premium models use similar unspecified treatments. The Roc5's MagSafe integration and solar capability do not introduce additional chemical hazards beyond the standard battery and coating profile. Competitors often provide equally opaque material data, making direct comparison difficult.
If you buy it
Keep the device away from prolonged heat (above 50°C / 122°F) to avoid lithium cell degradation and potential venting. Store in a cool, dry place when not in use; the waterproof coating may degrade over years of sun exposure, potentially allowing moisture ingress into the battery compartment. Do not disassemble or puncture the housing. If the battery begins to swell, stop use immediately and dispose of it at an electronics recycling facility.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Lithium-ion battery thermal runaway
If the device is physically damaged or exposed to high temperatures (above 60°C), the lithium cell can overheat, vent, or ignite. This risk is inherent to all lithium power banks, not specific to the Roc5, but users should monitor for swelling or unusual warmth.
Waterproof coating chemistry (PFAS or alternatives)
The weatherproof finish likely contains fluorinated or silicone-based compounds; Apple has not disclosed the specific formulation. If PFAS-based, potential environmental contamination occurs during manufacturing and disposal, though direct consumer exposure is low in normal use.
Plastic housing leaching (if damaged)
Polycarbonate or ABS housing does not leach chemicals under normal use. However, prolonged UV exposure or cracks may degrade the plastic surface; no documented leaching into food or skin contact has been reported for this product.
Magnet safety (MagSafe rare-earth magnets)
MagSafe magnets are encapsulated and pose no direct toxicity risk. However, loose magnets can be a hazard to young children if separated from the device; keep away from infants.
Battery recycling and disposal contamination
Lithium batteries must not enter landfill or standard recycling; improper disposal risks environmental lead and cadmium release. Apple does not clearly advertise take-back programs for power bank batteries, leaving disposal responsibility to the consumer.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
