I installed it myself relatively easily. What came does not have the mirror support that the photo shows but has another one. I have it for a mobile phone that works for hours in the machine and does what I want better than I expected. At full power on the mobile and it still charges strongly. I have stopped caring if the mobile is charged and how long the Powerbank lasts. It hasn't gotten wet yet but it is worth its money and more. I am coming back after heavy rain, it has withstood with the cable connected and works normally. Also, on the positive side, it has a battery indicator.
