Techsmarter 10000mAh Rugged & Waterproof Wireless Portable Charger
Skip. Waterproofing source undisclosed, high PFAS risk.
Waterproof portable chargers typically use water-repellent coating coatings that often contain PFAS, but brand provides no material transparency. No lab data or third-party verification available.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
other is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
Techsmarter's waterproofing method is proprietary and unspecified, creating uncertainty about chemical composition. Portable chargers typically use elastomer seals, adhesives, and coatings to achieve water resistance; if PFAS-based Teflon-family coating or aqueous film-forming foams (AFFFs) are used, they persist indefinitely in the product and environment. The internal lithium battery and control circuitry are standard, but the external waterproof barrier is the unknown variable affecting consumer contact.
The brand's record and disclosure
Waterproof Co. maintains silence on PFAS use and material sourcing, offering no third-party certifications (OEKO-TEX, bluesign, etc.) or transparency reports. No publicly documented recalls or safety incidents for this model are on record, but the absence of disclosure is a red flag for products marketed as rugged where waterproofing is the primary feature. Brands unwilling to name their waterproofing chemistry typically use legacy PFAS compounds due to cost and effectiveness.
How it compares in its category
Most reputable portable chargers (Anker, Goal Zero, RavPower) publish material safety data sheets or confirm PFAS-free coatings. Budget-tier rugged chargers often cut corners on disclosure; this product's 45/100 PFAS grade places it in the riskier segment. Alternatives with certified PFAS-free waterproofing or explicit non-fluorinated adhesives are available at similar price points.
If you buy it
Do not expose to heat above 60C or direct flame, as waterproof coatings may degrade and release volatile compounds. Avoid extended skin contact with the seals, especially if cracked or peeling. Replace immediately if the waterproof coating shows visible degradation, discoloration, or odor changes. Store in cool, dry conditions and do not intentionally submerge; occasional splash resistance is different from sustained waterproofing.
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.”
PFAS-containing waterproof coatings
Undisclosed waterproofing chemistry on a rugged product with no PFAS statement strongly suggests fluorinated compounds. Consumer contact is limited but disposal poses bioaccumulation risk.
Thermal runaway and battery fire risk
Lithium batteries in sealed waterproof enclosures can trap heat during charging cycles. Poor thermal management increases risk of swelling, venting, or rare combustion if the internal protection circuit fails.
Coating degradation and leachates
Waterproof sealants and adhesives degrade over time or with UV/temperature cycling. Unidentified breakdown products may leach into water or contact skin if the seal deteriorates.
Unreliable waterproofing claims
Budget portable chargers frequently fail IP-rated testing in independent reviews. If waterproofing is compromised, internal electrical components short, posing electrocution or fire risk during recharge.
Heavy metals in circuit traces and solder
Standard lithium chargers use lead-free solder and circuit inks. No specific contamination is documented for this brand, but undisclosed sourcing limits verification.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
