Dark Energy Poseidon Pro Charger
Skip. Waterproof chargers often use PFAS coatings, brand silent.
This waterproof charger brand does not disclose materials or PFAS status. Waterproof electronics frequently use fluorinated coatings; lack of transparency is a red flag.

The full breakdown
What it's made of and why it matters
The Dark Energy Poseidon Pro Charger uses an undisclosed waterproof coating applied to the housing, which is the core safety concern. Waterproof treatments on electronics frequently rely on fluorinated compounds (PFAS-based) to repel moisture, but Waterproof Co. does not publish material specifications or confirm what type of coating is used. Without transparency on whether the coating is Teflon-type coating, hydrophobic resin, or PFAS-based polymer, you cannot assess whether the product poses leaching or degradation risks during normal use or if damaged.
The brand's record and disclosure
Waterproof Co. provides no public disclosure of material composition, coating chemistry, or manufacturing certifications for the Poseidon Pro line. No established safety certifications (ISO, FDA, or third-party testing claims) are documented for this product. The brand's silence on PFAS and material transparency is a red flag in a product category where waterproof coatings routinely trigger regulatory and health scrutiny.
How it compares in its category
Waterproof phone chargers and power banks vary widely in coating strategy. Premium competitors (Anker, Belkin) either use Teflon-type coating with heat-management disclaimers or publish third-party testing results. Budget and lesser-known brands often apply unspecified hydrophobic treatments and avoid disclosure entirely, which is where Waterproof Co.'s Poseidon Pro sits. The lack of brand reputation or certification in the waterproofing space increases risk.
If you buy it
If you choose to purchase despite transparency gaps, avoid exposing the charger to high heat (keep away from direct sunlight and above 45C ambient temperature) in case coating degradation releases particles. Do not submerge the device in saltwater or hot water, as this accelerates unknown coating breakdown. Inspect the housing regularly for cracks, peeling, or discoloration. Replace immediately if the coating shows visible damage or if the charger produces unusual odors during charging.
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.”
Teflon-type coating fume risk (if coating contains Teflon-type coating)
Waterproof chargers sometimes use Teflon-type coating-based hydrophobic coatings. If the Poseidon Pro uses Teflon-type coating and is exposed to high heat or physical damage, Teflon-type coating degradation can release fumes. The brand does not confirm or deny Teflon-type coating use, so risk cannot be ruled out.
Coating leaching into skin/sweat contact
Waterproof treatments applied to electronics are not fully cured in many cases and can migrate or leach if the device is handled repeatedly or sweats. Unknown coating chemistry means unknown migration potential or skin irritation risk.
Degradation and microparticle shedding over time
Waterproof coatings on consumer electronics are known to degrade, peel, or flake when exposed to salt, sweat, or mechanical stress. Undisclosed coating type means you cannot predict lifespan or whether shedding particles are benign or toxic.
Off-gassing from unknown polymer or adhesive
If the waterproof coating is a multi-layer system with adhesives or volatile solvents, outgassing of VOCs during the first weeks of use is possible, especially in warm environments. No manufacturing data or curing protocol is published.
Electrical safety compounded by moisture entrapment
Poor waterproof coating application or degradation can trap moisture inside the housing, increasing risk of short circuits and thermal runaway. This is a secondary hazard tied to coating integrity, not chemistry, but brand silence on quality control worsens it.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 25% 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.
