Product Details



Description


Innovation Power Supply Design

With DAC Decoder
USB intelligent Charging
By internal NX3 it's a 2400mAh large-capacity litchium polymer battery,charging 0.5hour,it can work 5 hours.
220V working voltage can give full play to the op-amp and guarantee the good performance. NX3 is able to drive high impedance headphones which enough dynamic level range
NX-3 can adapt to the charge output of computer USB port and varitey of plugs. It automatically adjust the suitable charging current with the fastest speed to supplement the battery.

 

 



 

 

Fetures


Aluminum shell,although automatically produced in the high accurate processing center,it also need 46 technology from Aluminum block to finished product.

 

The two color appearance,was produced with polishing technoloy to get the effect which is the same as MACBOOK
air

When low battery,NX3 power source light will turn red to remind you to charge,and the remaining power can support the machine for
0.5 hour.
Double channel intelligent charge(patent)
no matter 0.5A output of PC USB socket or 1A output of phone charger.
NX3 can identify and automatically charge with signal channel(0.5A) or double channel(1A).
When use 1A,the charging time is less than 4 hours.
It will matching 1A charging current when the output of charger is more than 1A.
