This project is too good to be true. Suspiciously inexpensive, I was not excepting much. I got this for my PSVR2 controllers due to their short better life. These extend their battery life by 5x. They can be used to recharge after play or be used as a battery pack during VR play. I also use them on my head lamps and phone. They can be attached to any type c device for significantly extended play. I even used it on my Xbox controllers. Couldn’t be happier with this product. And it comes with 2 in the box. Read more

Still need a cord to charge this block but does make a small cheap little gift for someone. Read more
