I won't go into the details of the PK's battery and how it works. If you received your unit at 95% then there won't be any harm in using it right out of the box. The PK will last longer than the mPower and you should get really close to 20 hours of usage before the battery reports critical or the unit shuts itself off. The gague will jump +-10% meaning that the battery may really be at 90% but it may report 80% or 100%. I personally would let the unit run down to 20-40% before charging it up, but there won't be any harm in charging it sooner. A full charge from 0% to 100% takes just a little over an hour. Something to keep in mind when charging the PK is that it will always report 100% when plugged in, what I do is just leave it pluggede it in for at least 1.5 hours before taking it off the charge. In order to see what the gague really is at, it is required to unplug the AC Adapter.
