I still found the price of the BJ-6 charger for Ricoh GR bit steep, I have decided for this apparently identical Panasonic charger. (A third party is Sigma.) Abandoning the Ricoh logo given me 50% price advantage. The loader is suitable for Ricoh Battery type DB-60 and DB-65 (according to Panasonic S005). The supply by battery-net was prompt. The Sealed loader was delivered in a carton ungebrandeten without instructions or other Panasonic papers. (The simple operation is described in the camera but manual.) You may not sell the device from Panasonic individually, but distributed only as a spare part. I do not care, I have a compact, reliable loader at an acceptable price.
I almost forgot it: The power cord is equipped with 1.80 m unusually long. If you are traveling with the device, you might prefer a shorter.
