Active cooling on Qi2 wireless chargers works: Kuxiu D5 keeps phones cool at 25W, likely required for future 50W standard
Tags Hardware · Consumer · Infrastructure
The Verge's Thomas Ricker tested the $59.99 Kuxiu D5 Qi2.2 charging dock and found its integrated fan meaningfully reduces phone temperature during sustained 25W wireless charging. The reviewer concludes active cooling will become mandatory when the Wireless Power Consortium finalizes the 50W Qi3 standard, as passive thermal dissipation is insufficient at higher power densities.
Technical significance
This is a rare case where a charging accessory review signals a platform-level shift: Qi3 at 50W will require active cooling as a compliance requirement, not a premium feature. That raises BOM costs for all Qi3-certified chargers and may accelerate adoption of wired fast charging (USB-PD 3.1 at 140W+) for users unwilling to accept fan noise. Phone thermal design will need to accommodate charger-to-device heat feedback loops.
