I ordered a 4k Phone Charger model I tried it and the video quality was awful. I looked into the actual data of the video and found that instead of the 3840 x 2160 pixel that is standard, the video produced is actually only recorded in 1920 x 1080 which is HD, not the 4k I paid for. What makes it even worse is that it is recorded in 1199 x 810 which is only one-third of HD resolution. This is a complete scam and the company is banking on the fact you don't know how to check resolution of the sensor that is taking the video. DO NOT BUY.
