I'll let you know later, just got it, but it seems like quite a beast. Does take ages to charge, but such is the nature of Lithium batteries apparently (http://www.bbc.co.uk/news/technology-37255127).
If the battery charges too fast, generating heat, lithium plates form around the anode which can create a short circuit.
"Normally you would have a battery management system that controls the rate at which you charge," said Prof Grey.
"Batteries are optimised so that you don't charge too fast - if you do that you will plate the lithium."
This is also why battery charging can be a frustratingly slow experience, she added."
There is a dc out (switchable via the button on the top between the different voltages it does) with an included cable and adaptor. They're going for 70 bones on uk amazon at the moment.
