I'm sorry if this has already been covered. Search didn't come up with anything.
I'm unable to charge my 235 via a USB wall charger. I've tried several, and I've even tried a USB block, which has different ports for varying voltages. My 220 and 620 never had an issue doing this. Is it a voltage thing? It would really suck if I had to charge via a laptop every time, especially when I have to travel and don't bring a laptop.
Anyone else experiencing this, or have a solution?
