  "textContent": "A charging coil of a portable terminal charging apparatus is provided with a first detection coil, and a second detection coil disposed inward of the first detection coil and having a smaller diameter than a diameter of the first detection coil. The first and second detection coils are connected to a controller. If the ratio (V2/V1) of a second voltage (V2) detected by the second detection coil to a first voltage (V1) detected by the first detection coil is less than a first set value held in a memory between starting of conduction of the charging coil and connection of a charging load of the portable terminal, the controller performs a safety operation.",
