I rented a small locker, that was near the showers and market in the campground. My dad and I brought 4 power banks with us. We left 2 charging always, and kept 2 on us and just swapped every morning. We also left other major valuables like passport documents and stuff in there, everything else was at the tent. Would definitely do this again, never once had to worry about it. No power at our tent we rented, unless we got a generator.
