Actually I don't recommend this, not even with warning note. There are better ways do cope with this: hotswap or external LiIon charger/other cellphone. Battery has max chrg V of ~4.2V and max I of ~1A. Anybody needing to know more on it, shouldn't even think about it. The ones who think they understood the above: formating charge current when bat is deeply discharged shouldn't even exceed 50~100mA! Otherwise U might kill bat. LiIon is tricky! /j
