Does anyone know what portable backup chargers are dual voltage? I will be plugging them into outlets in Europe and not a computer. I'm not sure how to know if this chargers will work plug into a wall in europe. Stuff similar to this:
Nothing online says if it's dual voltage or if it can recharge itself while plugged into a wall. Has anyone re-charged their portage battery via the wall in europe and not usb to a PC? If so what brand of charger are you using?
Thanks
