Regulatory certification documents have revealed that Samsung is actively preparing a next-generation desktop charging accessory designed to accelerate wireless power transfer across its mobile ecosystem. The accessory, officially registered under model number EP-N2520 and designated as the Samsung Magnet Wireless Charger Duo, recently passed through the United States Federal Communications Commission equipment authorization database. The documentation details higher wireless wattages, magnetic coil alignments, and dedicated power management protocols for simultaneous device charging.
Regulatory Filing Outlines Magnetic Qi2 Upgrades
The regulatory filing under FCC identifier A3LEPN2520 identifies the desktop unit by its commercial name, confirming a dual-pad charging architecture tailored for modern handsets and smartwatches. Label artwork and operational descriptions submitted to the agency feature formal Qi2 branding rated for 25W output. This represents a significant evolution over current magnetic pads, which typically peak at 15W across older wireless charging standards tracked in Passionategeekz accessory insights.
To support higher transfer speeds, the EP-N2520 relies on advanced USB Power Delivery and Programmable Power Supply negotiation. Laboratory evaluation documents show that the charging stand requires an input overhead of up to 45W, drawing 20 volts at 2.25 amperes from an external wall adapter. Test setups paired the device with Samsung’s EP-T4511 45W fast-charging brick, suggesting the company could potentially bundle high-wattage power bricks in premium retail packages covered across Passionategeekz Samsung reporting.
Dual Device Power Allocation and Thermal Behavior
A crucial technical nuance uncovered within the regulatory disclosure relates to power splitting during concurrent usage. When charging a compatible smartphone in isolation, the primary magnetic pad delivers its full 25W headline speed. However, placing a companion wearable on the secondary puck simultaneously alters the power curve: the phone channel steps down to a continuous 20W ceiling, while the dedicated watch coil receives up to 5W of power.
The secondary charging module is engineered around coil assembly EP-OL715(D), configured specifically for high-frequency 5W fast-charging protocols. Internal test telemetry recorded compatibility with flagship wearable hardware, explicitly referencing the Galaxy Watch Ultra 2 under model code SM-L715U alongside secondary hardware model SM-L325U.

Ecosystem Alignment Ahead of Next-Generation Flagships
The timing of the FCC grant aligns closely with component preparations for Samsung’s upcoming premium smartphone refresh. As high-density silicon-carbon batteries and upgraded thermal dissipations become standard across flagship lines, pairing handsets with 25W magnetic wireless charging brings Samsung closer to matching top-tier wired speeds without mechanical cables. Industry watchers anticipate the accessory will launch alongside upcoming premium phones detailed under Galaxy S27 series leaks and wireless charging standards.
While official commercial retail pricing and regional shelf dates remain unconfirmed, the completion of telecommunications compliance testing confirms the product has transitioned past prototyping into pre-production stages.
