Great VR device, however it only has about 2 hours or so battery life. I experienced a lot of issues charging the device while in use using the provided cord and power adapter. It seemed to only charge for about 15 minutes and then would start draining. Support from Oculus advised this was as intended for "health and safety" of users. I understand this as I could only use the device for about 2 hours max before starting to get sore, however if I were using the device on a lounge or something while watching netflix, it would be frustrating if a movie did not finish in the time the battery lasted! My workaround for this is to simply use a portable power bank. Having this plugged in when I start using VR, keeps it at 100% for at least 2 hours (when I stopped using it).
