Going to NYC during a busy time soon. We will be out and about walking all day and into the night too. There will be even more people out as it will be the marathon and other races. What size battery back up would you bring for your Max? I will be using my phone for everything from walking navigation, subways, entrance passes, photos etc. Don’t want to be left with a dead battery before we get back to the hotel at night!

Assuming you will have a messenger bag or back pack? Take two if you have them handy already. 10K mAh would be my minimum.

I’ll be carrying stuff for sure! I think my friends might also forget to bring batteries or won’t anticipate needing them. I did suggest they bring one though:). I know when it is packed and there are tons of people at an event, the phones take more battery trying to get bandwidth etc.
