What's up community -
Seems to be plenty of questions on the reverse, but I can't find anything about an under voltaged external battery. Most seem to go to 19v as the highest output.
Have a Lenovo u310 ultrabook. The power adapter says it's rated at 20v.
So my question, is whether or not a 19v external battery would have enough juice, and/or if it could damage my laptop battery.
I assumed only OVER voltage would harm it. But don't want to assume with electronics...
Thanks guys!
