It comes with a usb lead which is the same as a blackberry lead and then you have to get (if you havent already got) a three pin plug with the usb attachment. Any more question will be happy to answer Nick

The instructions that come with the Anker says "Do not try to charge and discharge the Astro 3 at the same time as this may reduce the battery lifespan. So even though it is possible they indicate it should not be done unless you want to reduce the useful life of the Anker Astro 3.

When there's no light on, it means it's fully charged. I just use any random USB cable plugged into a multi-port USB power supply. What you describe seems to be the right behaviour.

I'd be very surprised if this didnt charge your MeMo. As long as the power source is USB, there hasnt been a single item this battery pack hasn't been able to charge for me. (Phones, Chromebook, iPads, GoPro's etc)

Lithium batteries in general hold a charge quite long but with age the length decreases obviously. This battery I had half charged 3 weeks after a bike tour and used it this weekend and it still had half a charge.
