I am currently building a gauntlet for a costume. I would like to put up a standalone touchscreen display in it. This should be rechargeable or at least battery powered. I am not good with wiring, so I would like to buy something online that's pre-wired with the battery. I see a lot of products online but not sure which one to buy. Most of them have smaller displays, so I need options with a bigger screen and a smaller screen. Can you suggest me readymade ones that I can buy it right away online?
