If you are going “way out” then neither.
The map functions work ok in the city, but you get up on a mountain and they will not work without cellular service.
Plus, they are battery hogs. How are you going to charge them?
Topo Maps is an app you can download to your phone.
Works like a GPS device on your phone. It works anywhere.
You have to know the area you will be hiking/camping in and download the 1:25,000 map sheets at home through your Wi-Fi.
Yes, it is a battery hog but works well if you only turn it on now and again to check your position.
When I’m in the woods I carry two different battery chargers. The Mophie will give me two charges from 10% and the Power Traveller will give me three. Starting with 100% I’m good for a week.
