Cannot fault this at all!
With Usb's swapping to usb-c's and multiple devices to charge this little plug is a godsend. Its small enough to sit in the socket without really being noticed. I no longer spend half my day swapping plug's, ive currently got 2 usb-c wires in it and a Usb and the charge time on devices is still great. It doesnt get overly warm either even after running for a fair few hours.
I definitely need more of these
