Rain leaked through the Ella guesthouse roof onto my backpack and power bank — dry it out or demand a room move?

Move the bag off the wet patch first, power down wet gadgets, dry with towels and a fan, and ask for another room if the drip continues. A decent host will move you without a fight after a roof leak onto gear. Photograph the ceiling and the damp bag before you shift things. I will not invent compensation amounts — ask calmly for a dry room and help drying. Rice is not magic for ports; silica packs and air-dry are better. If the leak is still active at bedtime, do not tough it out under the same crack.
