Powerpack for iPhone used for Watch

I was planning to go for long weekend hiking (or any 2 days outdoor activities) where you wouldn't find any power point in the bush. Do you think I can use my iPhone portable power pack to recharge the watch? I got something similiar like this:

Definitely, as longs as the portable charger you're using lets you swap out different charging cables you can just plug in your  Watch's charging cable and charge it up.

I also have a portable charger and plan on having it on standby the first few days I have my  Watch due to the fact that I'll be stress testing it like crazy.
