I sat in a waiting room yesterday for several hours. I hadn’t charged my phone and iPod fully. The iPod was first to go while I was reading a book in the Stanza library app and checking email intermittently. I had to go there in a hurry so I didn’t grab my bag with the AC/DC kit. I know…cardinal EDC rule broken. I have one Energizer xPal battery. I need another one to keep in my pack. Of course this will increase the weight but there were no outlets in sight.
