Exposure just confirmed charge light to full mains USB at 1ah only 1h longer then mains charger at 1.4ah and using a power pack as cache with 2a output should not damage it. As well it should work with minimal battery power left while loading so be in fact a dynamo light?
The sinewave will give enough power for this; what do you think?
As well which cache battery have you got, for my setup the magic word seems to be pass through charging? Was thinking of http://www.amazon.co.uk/Zendure-A2-Portable-Charger-6000mAh-Silver/dp/B00ICYOUCK/ref=sr_1_1?ie=UTF8&qid=1413537966&sr=8-1&keywords=zendure+a2
At a rough guess I'd say it charges around 1000 ma/h. Given it takes about 1h30 to charge my iPhone. But that's a guess.
And you wouldn't need a big 7000 pack. Just get something smaller.
