So I did the same 43% test with the stock cable and charger, Here are all of the results together:
Stock cable, stock charger: 43% to 60% in 1 hour.
Pogo cable, stock charger: 43% to 64% in 1 hour.
Pogo cable, 3.1A charger: 43% to 64% in 1 hour.
Take from that what you will. Personally, even if the Pogo cable didn't offer any gain in charging speed, it's still worth it to me. I read e-books on the N10 in bed at night and when I get sleepy and put it down it's much easier to snap on the Pogo connector than it is to maneuver the micro-usb connector into its little jack. Not to mention safer if it's dropped.
