got it a while back , found it a good use during sandy, charges 2k+mah phone approx in under 3h time. a bit heavy but very solid and scratch and short drop proof.
anyone tried to charge ipad mini? wont charge it. very hard to calculate how many watts this unit is some say around 30 most shops say its 10watts no amps info no wattage info , not sure if you could even charge laptop with it or even use , ipad mini needs 10 watts and it wont charge with it , was using it flat at 12-1pm right under the direct sun cant figure out how to make it work, no extra adapters or anything else was used simply ipad mini to solar panel by usb. the good thing is it does charges cell phones pretty good in low light while other portable solars dont even work in low light so i was assuming it has some higer wattage then 10watts.
