A:AnswerThese aren’t compatible with elite series and you are able to charge these without an Xbox.(I charge these using my Amazon fire Tablet charger)
A:AnswerI would say no as they are not branded for Razer. All you could try is buying some and look at the charging contacts to compare with your Razer device and if theres no perfect alignment return them to Best Buy but ALL things will have to be compatible especially with the rate of charge and output voltage etc.
A:AnswerIt’s 20 hrs per battery pack. 1 controller, 2 battery packs = 40 hrs of game play.

A:AnswerThe battery pack has female micro-USB port. The kit comes with a cable. One end of the cable has USB and the other micro-USB. The USB connects to the Xbox and micro-USB connects to the battery pack. They recommended to charge from XBox using one of the USB port.
