I was very pleased to finally be able to use the USB tip that came with my travel adapter a couple of years ago. It's not working well at all. :(
I've got one side of the Y plugged in to my X220 (tip 20V) and the other side to USB. My phone was at 10% when I started and it kept giving me low-battery warnings while plugged in. I was using a generic USB cable and a mini-to-micro adapter. The phone was recognizing it was plugged in, showed the charging symbol, then every couple of minutes gave the 10% warning, which makes me think it was losing its plugged-in-ness. Eventually it got down to 8%. Now I've got the stock Samsung USB-to-micro cable plugged in to the L9 tip and it's climbed back up to 9%. Perhaps either the adapter or the cable were faulty. Guess I'll have to test further (try them with the Samsung 120V adapter etc.). That said, I can't find anything that specs the L9's output. Is it 500mA, 1A, 2A, or something else? I know a notebook port (500mA) takes forever to charge compared to the Samsung wall adapter (2A I think). So if the Lenovo L9 is 500mA I might as well use the computer, and better still I should shop for another couple of 2A plug adapters.
