I don't. it also depends on the capacity of your battery. with 4500mw i don't notice a different consumption than normal.

To use a power bank you need a special adapter. Don't know wich one would work for iphone. I use mine with the Steam Deck and Samsung devices, to charge and use the glasses at the same time I use the adapter from Viture.

it depends. there's a VR mode, in which case the image moves, and a screen mode, in which case it doesn't move. The real problem is the viewing angle. I have to lower the arms of the glasses on the outside of my ears, halfway up, to see the whole screen... otherwise it's fine for watching films.

Unfortunately, the manufacturer does not specify the IPD, only the dimensions of the product 175mm x 166mm x 51mm, so direct contact should be made with manufacturer support for more accurate information.

Good day After checking the manufacturer's website, here is the information: "The TCL NXTWEAR S is an evolution of the TCL NXTWAR Air, offering a range of features that free users from fixed screens. The smart wearable glasses offer a wide viewing environment equivalent to a 140-inch screen four metres away, with two 1080p Micro OLED displays that provide a private, high-quality viewing space. TCL NXTWEAR S transforms everyday tasks while enhancing the leisure activities of gamers and streamers - anywhere, anytime."
