Sony video camera DCR-SR52, charging dock and remote control.
I have tested this when it is plugged into the charging dock and connected to mains and it appears to work fine. However the battery is only holding a very small charge and flattens very quick.
Looking on eBay the charging station alone is about £30 and the battery can be bought for £15.
This comes in a carry case and with the output lead, But no additional storage.
