This mark reads "Dai Ming Sei Ka Nen Sei" (太明成化年製), "Made during the Seika Reign of the Great Ming Dynasty". It is a Japanese forgery of reign marks from the Chenghua rule in China (1465-87) that dates to the Pre-1868 Edo period but also was continued afterward. Some of these marks are seen with the "大" (Great - Da in China) character, also pronounced "Dai" in Japan.
Your photos are too fuzzy for a guess at whether the charger is an older or newer piece.
