you can dine with my charger only USB devices and not charge it via USB, but I wanted to actually have. well, then I am just a crush. The mounted LED is actually a joke! it lights only minimal brighter than the red charge indicator LED, which reminds me of fireflies. If you already incorporates a LED then you should take a right. To note the positive side is the rather high power output which was my measurement at about 0.7A. That is the way, far from the now that is a maximum that was just the highest that has swallowed my USB device.
