okay, so I was trying to save money. My regular Sony charger becomes defective a no. of years ago. I should have buy a new one. But instead I use the other charger from my NH1. I bought my NH1 directly from Japan, this is the gold plate version, so the charger is meant for Japan voltage system, a Sony AC-ES60BK, w/ input AC100V, 50/60Hz 12 VA, output DC 6V, 800mA
the original charger, was 115V. Since then, I notice this charger only takes 15 to 20 min. to charge a near empty battery, and likewise, the battery may be dropping juice somewhat faster. I am also certain the original charger takes much longer than 15 to 20 min. to recharge the battery
Moreover, for those who own the North American version of your NH1, could you please post a photo of the front plate of your charger, there is some specification that I need
