Has anyone tried this Techlink Recharge 2600 USB Charger/Battery Pack

[Yptcn]

I was wondering if anyone's tried charging their watch with an exterior battery pack like this one , sold by  ? I could really come in handy for long plane flights or when far from a power source

Assuming the Techlink Recharge 2600 is 2600mAh and the 38mm is 205mAh (42mm is probably around 240mAh) then you could probably get around 8 to 10 chargers.
