That ' s a myth she always said she would work with the Russians before instituting a no fly zone . She never planned to shoot down Russian planes . clintonsyriarussiaus 5614695 de 4 b 0 fad 1591 a 0574 <| sep |> No , because as I said in my reply to the parent comment , it ' s not a good solution physically . I ' d have to install a socket that is totally nonstandard ie , feeding a 230 v AC socket with 110 v DC and at some point , someone will try and plug something incompatible in and it ' ll cause issues on both the supply side and to whatever is plugged in . sockets don ' t fit into the space envelope available . sockets introduce multiple failure points as the environment has a lot of vibrations and over time , the socket will work loose . I ' d have to use a short USB cable to go between the charger and panel mounted socket rather than hardwiring . There would be some complexity in building in multiple USB ports . I potentially need 200 chargers working with a range of voltages and I want a solution that uses standard parts and just change the dcdc converters . It just seems like a bit of a rubbish solution .
