Is this really workable? Batteries in watchband?

For me my watch lasts all day and has lots left over at the end of each day. I use the watch when I am awake and when I am sleeping my watch goes on the charger. For me this works good and in my opinion if your watch lasts all day and you can charge it at night then you don't need battery watch bands unless you are going to be somewhere without plug ins for more then one day then external battery packs or battery watch bands may be a good idea. I would go with a battery pack over a battery watch band because then I can also charge my phone and what ever other devices I have with me.

Hello,

Another thing you can consider is a backpack or purse with a built in solar panel.

My 10 year old has a backpack with a built in panel that also has a built in battery backup. Indoor lights are strong enough for his devices to charge.

HTH and good luck.

In q2 tthere is going to be a portible battery bank that is for the apple watch it debeued at CES this year. It's the size of a credit card and can attach to your keychain. http://www.macworld.com/article/3019014/mobile-accessories/griffins-new-apple-watch-travel-charger-could-keep-you-off-the-grid-for-days.html
