  1. A tale of two Droks: one good, one not I supported PortPilot on Kickstarter … and I like it.But, I wanted to try the much less expensive Drok device.[Amazon is conflating the *TWO* different Drok USB analyzer products … my review of the Drok Dual USB device is showing up for both it and for the Drok Mini device … so, I’ve edited the review to discuss each device.]1. Drok Dual USB …The DROK dual-usb hub/charger/etc. is significantly less expensive than the PortPilot and does a great…

  2. Find the truth about phone and GPS power draw I never really knew how dirty the usb specification was until I tried different combinations of stuff in different ports around the home and office. I have a Lenovo keyboard at work I love for its shortcut buttons and usb ports, but don’t try to charge anything but a fitbit off the ports. . they drop in voltage and amperage very quickly, leaving them best used to run a wireless mouse dongle or other very low power device.And phones can use well over an amp to charge if you let…
