Nokia Charger

Seen physically, Nokia only has 2 charger, 2 mm and approximately 3.5 mm charger. But if you looks at the detailed specification, you will notice the difference, that is the current (I think the voltage is same). Here is the comparison table:

Type	Picture and Description	Connector	Output
AC-3	low-end charger	2 mm	DC 5V 350mA
AC-4	high-end charger	2 mm	DC 5V 890mA
AC-5	small-high-end charger	2 mm	DC 5V 800mA
AC-6	mid-ranged charger	microUSB	DC 5V 550mA
AC-8	high-end charger	2 mm	DC 5V 890mA
AC-10	high-end charger	microUSB	DC 5V 1200mA
DC-4	high-end car charger	2 mm	DC 5V 890mA
DC-6	mid-ranged car charger	microUSB	DC 5V 550mA
DC-9	mid-ranged car charger	2 mm	DC 5V 700mA
DC-10	high-end car charger	microUSB	DC 5V 1200 - 1500mA

So what the effect of different current?

For example you have a battery with 1000mAh. If you use AC-10 charger, it will charge your battery in less than 1 hour (phone is switched off). The current affects the charging time needed. Higher current means shorter charging time. But it may decrease your battery lifespan
