Techsmarter Waterproof Rugged Laptop Power Bank
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic body, 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 Techsmarter Waterproof Rugged Power Bank is made of, ingredients and materials
This power bank uses a plastic body (material type not specified in available documentation, likely ABS or polycarbonate) with sealed construction for waterproofing. Plastic housings in portable electronics are inherently inert when unexposed to extreme heat or damage. The waterproof rating relies on physical seals and design rather than chemical coatings, which eliminates a major pathway for hazardous finish migration into food or skin 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.
BPA & bisphenols
Generic plastic composition is not declared. If the casing is polycarbonate, BPA leaching is theoretically possible under high heat or extended sun exposure, though risk is low for an external-contact-only accessory. Direct food contact is not a use case, reducing practical exposure.
Source, FDA ↗Microplastic shedding from surface wear
Repeated handling and weathering of plastic surfaces can generate fine plastic particles. This poses minimal direct hazard for a power bank (not in food or water intake), but environmental shed is worth considering if dropped or heavily abraded over years of use.
Lead
Standard practice in consumer electronics includes lead solder and trace cadmium in rechargeable lithium battery terminals. Exposure risk is negligible if the unit remains sealed and unbroken. Improper disposal (landfill vs. electronics recycling) poses environmental risk.
Source, ATSDR ↗Seal degradation over time exposing internal components
Rubber or silicone seals on waterproof cases naturally degrade with UV exposure, heat cycling, and flexing. Loss of seal integrity can allow moisture ingress, which may trigger corrosion of internal metal contacts and battery leakage of alkaline or lithium electrolyte.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Flame retardants
Consumer electronics are not typically flame-retardant treated in their external plastics in the way textiles or foam are. No recall or testing data suggests brominated or phosphate-based flame retardants in this product line.

The brand's record and disclosure
Techsmarter has not made public statements about material safety, heavy metal content, or flame retardant use in this product line. No recalls or safety controversies have been documented for this specific model. The brand's silent stance on PFAS and material composition is typical for consumer electronics accessory makers and does not necessarily indicate a problem, but limits independent verification of manufacturing practices.
How it compares in its category
Waterproof power banks in this segment typically use plastic housings with mechanical seals; chemical waterproofing coatings (which might contain PFAS) are less common in battery cases than in textiles or cookware. This product sits in the mainstream tier without premium material transparency claims or budget ultra-cheap construction flags. Sealed design is a safety advantage over non-sealed alternatives, which can trap moisture and degrade internal components.
If you buy it
Keep the charging port covered with its included cap when not in use to maintain seal integrity. Do not expose the unit to prolonged direct sunlight or heat above 60°C (140°F), as internal battery and plastic can degrade. Replace the unit if the seal cracks, the casing splits, or charging becomes intermittent; water ingress can trigger short circuits. Store in a dry place and check seals annually if used frequently in wet environments.
