Japanese camera site DCWatch has reviewed the PQI Air Wi-Fi Micro-SD to SD adapter. The adapter features a built-in Wi-Fi transmitter but, unlike rival FlashAir or Eye-Fi cards, does not feature any internal memory of its own – instead allowing you to swap MicroSD cards in and out. The adapter communicated with smartphones via an Android or iOS app from where you can browse and download images from the camera. The system allows you to swap inexpensive standard MicroSD cards, rather than buying multiple Wi-Fi cards, also allowing you to upgrade the speed or capacity of card without having to replace the Wi-Fi component.
