The CED M2 IR-Power Bank Cable is a specially designed USB cable that will power the CED M2 Chronograph Infrared Screen Set from any Power Bank with 5V 2A Output minimum capacity.  

In fact, testing indicates that a 20,000 mAh power bank should run the IR set for over 10 to 14 hours of continual use depending on the age of the Power Bank itself.  There is no need to purchase a NiMH Battery Pack or use AC power to run your IR Screens!  With this special designed USB cable, most power banks will do the job instead.

NOTE: Power Bank or any other M2 accessories shown in photos not included. Only the charge cable.
