So while going through inventory for my company, I came across an Exilim Z75. I have a Nikon S8100, plus an 8MP camera on my phone, so I am not too worried about this, but I thought it would be nice to have a camera for work only to take pictures of the office and equipment and various items. Incase I do not have my Nikon around, or perhaps someday I am not here and someone needs to take a pic. The problem is all I have is the USB cable and the camera. I do not have the AC adapter. the USB cable looks like it is a charging cable, but I have tried to plug it into my computer and several other USB AC adapters, and nothing happens. Can I not use just any USB charger? Or am I doing something wrong?
