The batteries are nowhere near 4800 mAh. Otherwise they work fine.

As usual for really cheap things like this the capacity of the batteries has been grossly overstated. You can tell that instantly because they are feather light next to a real xbox battery pack. A real battery pack weighs about the same as two Amazon Basics NIMH AA Rechargeable batteries which makes sense because that's pretty much what is inside the plastic case. These barely weigh anything at all, not even a quarter of the real thing. As a result the battery only lasts about two hours from a full charge. Otherwise they work fine. The cables work like they are supposed to and seem to be of decent quality. NOTE: because of the way wireless controllers work, you cannot connect the cable and then use it as a wired controller. The cable is used for syncing and charging ONLY, no positional or button data is transmitted over the cable. This is not the fault of the cable, it's just the way the controllers are made. If you want to connect them to a computer you will need the correct wireless usb adapter which you can find for around $15 here on Amazon.
