Ahhhh... I should add one more thing for your emergency survival kit! I have a solar panel that charges to USB outputs... It would be the perfect thing for recharging that spare battery!
Anyway, I hope you are surviving the Loadshedding with some humour intact. At least you live in a warm climate... it would be a disaster in snow!
I must find out if that Solar Panel is available here. Some parts of our country do get the odd days of snow, but not continuous and none here where we live
Thanks for your valued feedback @ bengy!
