There was some Irish guys on this forum who went Africa way and one of them took a soldering iron with them..
And they used it.....!!!
So parts are varied on what you may need....
Indeed, I was one of them! Incidentally despite the 40C heat in Mauritania it didn’t work well due to the wind so I am not sure it’s an essential tool. But cable ties, duck tape, credit card and a sense of humour definitely are!
