To keep charged, a portable charger has to be connected to a power source, such as an electrical outlet. Because there are no power outlets on Kilimanjaro, you will need to pack a portable charger. As a result, if it runs out of energy, it won’t be possible to refuel it until the end of the journey. This includes all of your other gadgets. If your portable charger can carry enough energy to power all of your gadgets for the length of your journey to Kilimanjaro, it’s worth taking. However, keep in mind that in cold weather, batteries drain much more quickly than usual. As a result, a solar charger could be the finest and most dependable option.
