Hoi - I am not sure whether this plug will work everywhere - have a look here: https://world-power-plugs.com/de/schweiz-nach-nepal - at best, a universal adapter would certainly not be wrong. Then: https://nepal.de/reiseinformationen/telefon-internet-strom/ ... electricity is obviously not quite as stable as it is here... At best, I would recommend the use of a power bank for charging when there is no electricity (at least mobile via USB, your cam(s) via USB, if the cams can be charged via USB) - which you can also take with you on the plane and which is not so heavy to lug around... Universal adapter: https://www.digitec.ch/de/s1/producttype/reiseadapter-2540?pdo=2191-15201%3A296110&tagIds=77-100 Powerbanks and the airport: https://www.flughafen-zuerich.ch/en/passengers/fly/all-about-the-flight/what-is-allowed-in-your-baggage Check with your airline to see what's OK and what's not.... the powerbanks would be here: https://www.digitec.ch/search?filter=t_pt%3D2040%7C463&q=powerbank Have fun in Nepal (I would also like to go there again), stay healthy and have a happy new year.
