Phihong has developed a folding blade adapter that, with a 15 mm thickness when the blades are folded, is said to be the thinnest available. The PSA05F adapter is available with 5 V and USB A socket output, and meets the requirements of the United States’ Federal Energy Independence and Security Act of 2007 (EISA) as well as Energy Star EPS 2.0 requirements. Suitable for use in personal electronics, including digital cameras, PDAs, and MPEG players, the PSA05F adapter’s thin profile saves space, storage requirements and shipping fees due to its light weight and smaller size. Phihong’s PSA05F adapter features a fully regulated 5 V output, Level V Energy Star efficiency compliance, 5-Star Standby Power and 72.3 percent average efficiency. Additionally, the adapter carries cULus, TUV, SAA, C-Tick, and CE safety approvals and markings. The adapter also features short-circuit protection with auto restart and over-voltage protection. It measures 2.36 inches in length by 1.85 inches in width by 0.59 inches in height and weighs 3 ounces.
