As you can see, I have also replaced the micro-USB plug with a female USB-A socket, so that I can plug any USB-type cord into it (micro-USB, mini-USB, iPhone-charger-USB, etc). This particular version is not particularly weather-tight. The actual size of it is larger than the previous shrink-wrapped version also. But it is certainly smaller than the PVC-pipe version, and should serve me well.
Haidee and I are heading off on a two-week cycle tour starting in a couple of days, so both chargers will get a thorough testing 🙂
