Techsmarter 10,000mAh Waterproof Wireless Power Bank
Waterproof power banks often use water-repellent coating coatings; Samsung doesn't disclose PFAS.
Waterproofing in consumer electronics commonly relies on Teflon-family coating or PFAS-based treatments. Samsung hasn't disclosed PFAS content or committed to PFAS-free materials.

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
Waterproof power banks typically use water-repellent coating coatings; Samsung does not disclose whether this model contains PFAS or PFAS-free alternatives. Environmental and bioaccumulation risk is moderate if PFAS-containing coatings are used.
Source: ATSDR ↗Plastic off-gassing and leaching
Unspecified plastic housing composition creates uncertainty about volatile organic compound (VOC) emissions under heat or UV. Risk is elevated during charging when internal temperature rises.
Coating degradation over time
Waterproof coating durability and degradation products are not published by Samsung. As coating wears, micro-particles or leached chemicals may shed into the environment, especially if the device is heavily used or exposed to abrasion.
Battery thermal management and plastic stability
Lithium-ion power banks generate heat during wireless charging cycles. Generic plastic housings may not maintain structural integrity or chemical stability under prolonged thermal stress, though no specific failures are reported for this model.
Lack of material transparency
Samsung's absence of published material composition data for this product is consistent with industry-wide poor disclosure. Consumer inability to verify safety claims increases uncertainty and limits informed choice.
The full breakdown
What it's made of and why it matters
This power bank uses a plastic housing (material type not specified by Samsung) with an undisclosed waterproof coating. Waterproof coatings on electronics commonly rely on water-repellent coating (water-repellent coating) chemistry, which historically included PFAS compounds, though some manufacturers have shifted to PFAS-free alternatives. Without Samsung's material disclosure, the specific polymer composition and coating chemistry remain unknown, making independent verification of safety difficult.
The brand's record and disclosure
Samsung maintains largely silent public positioning on PFAS use in consumer electronics and does not publish material transparency reports specific to power bank coatings. The company has faced industry pressure on chemical disclosure but has not committed to third-party PFAS certification for this product category. No known recalls or safety violations are on record for this specific model, but Samsung's lack of proactive disclosure is typical of the consumer electronics sector.
How it compares in its category
Most waterproof power banks in this capacity range use similar plastic housings with proprietary waterproof treatments; few brands publicly disclose coating chemistry. Some competitors (e.g., Anker, Goal Zero) have begun publishing material safety summaries, but Samsung does not routinely do so for this category. Wireless charging adds minimal additional chemical risk but increases internal complexity and heat generation potential during use.
If you buy it
Keep the device away from sustained heat (above 40 degrees Celsius ambient or prolonged direct sunlight), as plastic housings can degrade and coatings may leach chemicals. Avoid charging in high humidity or enclosed spaces where off-gassing from the plastic casing could accumulate. Do not puncture, disassemble, or expose to high-pressure water despite waterproof rating. At end of life, dispose through electronic waste recycling rather than trash to reduce PFAS and plastic contamination risk.
