PoE to Micro USB Converter

Someone recently showed me their latest cheapo Chinese import gadget - a PoE to Micro USB Converter that they were using to power a non-PoE enabled device.  As I'm never too far away from a PoE enabled port and they've reached a reasonable price point (£5.19 inc P+P) I thought it was worth picking one up on Ebay. I ordered one on the 12th January and it arrived on the 26th which puts shipping bang on 2 weeks - not bad from China.

I've done some testing and it seems to be a little picky about its power source. The converter works fine with a 'proper' HP Procurve managed switch, but with a Netgear Prosafe switch the power light pulses on and off and the USB cable doesn't power up.

The converter is also lacking the molded tab to prevent the RJ45 from snagging shown in the picture above, so I'm not too optimistic about how long it will last before it needs re-crimping. I'm considering opening it up and placing it in a new enclosure with a proper USB A female socket to aid compatibility with other devices such as iPhones.

Overall for £5.19 I can't complain too much. I will use it a little more 'in the field' and do some load testing and follow up in another post.
