I believe this is a second generation Flir One so about 10 years old. Device still works with the Flir One app available for free on the App Store. Everything you see in the pictures is everything that comes with it. Unlike newer generation this does not run off the battery from the phone so needs charged before use via mini USB cable. You could potentially plug it in to a power bank while attached to the phone but I have never tried it. The camera powers on and works as it should but you get about 10 minutes before the battery dies. I bought this second hand for a specific job which has now been carried out.
