If it is 62 watt hours, that is a pretty big power bank. I can't imagine you would be able to push a lot of current through the electronics in that one unit for charging regardless of how big your USB supply is.

If you had two power banks, you probably could cut your charging time in half by having separate chargers for each.

If I recall correctly, you used to use a Forumslager (spell?) for bike touring. My big power bank that I bought for bike touring is 44 watt hours. During a bike tour I assume that on average my Sinewave Revolution puts out 2 watts, thus from empty to full would take 22 hours of rolling time. I learned to be patient.
