USB Charging Doctor


I have seen a lot using a Charging Doctor or Safty USB tester.
I want to get one since I want to be able to REALY see the current flow Amperage and also the CORRECT Voltage of my chargers - So I will be able to get ONLY the one that works (next time I purchase)
I have seen Don also using one.
I would be happy if you could suggest the one I should get within a reasonable price range :slight_smile:


I am thinking to get this one:
What do you think? It looks OK.
