When flying EWR-ORD in F on the 737-900 and ORD-PEK on the upper deck of the 747, I was having problems charging my devices. It seams that sometimes, not always, when I plugged my charger into the AC power, the green light would go off, and it would come back on when I pulled it out. It happened more on the second half of both flights. I was only trying to charge my iPad with a 2.1 Amp charger. Thankfully in J they had the USB plug as well. While that did not provide enough power to charge my iPad, it definitely kept it from draining as fast.

Flying home, we will be on the sCO 777-200ER NRT-EWR in Y. We are taking codeshare NQ or NH from CAN to NRT and we only have about two hours on the ground, so I may not get everything fully recharged. We are returning in Y so we won’t have the USB plug.

Are there any tricks or idiosyncrasies with the power that would prevent it from failing halfway through the flight? Is there anything I can do to prevent the green light from turning off when I plug something in? Is there anything the FA’s can do if I have that problem?

Thanks in advanced.
