more than 9 V to charge Motorola MC220R

I got my first set of MC220R and as expected, the AC adaptor was 110VAC input only and outputs 9VAC/200mA. Since 220VAC is prevelent here, I got a 220VAC-9VAC/1A adapter from local market.

This adapter however is not a very good one and outputs around 14VAC (under no load). Havent been able to measure on-load voltage yet.

Can someone tell me if this voltage will reduce the battery charging time and how much.
