Smartronix has a USB power monitor and it’s ideal for those who want to regulate what power is coming from a USB device. Most notably would be the ability to test power from a suspect defective drive or gadget. With so many useless USB toys made in cheap factories over seas, one can get a product which plays havoc with your system. Most problems always come from power.
Granted the power meter probably takes more juice then any USB power gadget your testing, but again, this is designed for the hobbyist or guy troubleshooting some gear.
This is also a good device to test products which claim to fall into the USB-IF specification for a USB device, something like this USB power meter could help prove your case against an overseas supplier who’s not fessing up to their poor quality work. (can you tell we’ve ran into this problem on multiple occasions !)
Too bad it doesn’t measure calories, otherwise we’d find out just how hard that USB humping dog is really working.
