There are basically two options for supplying power to astronomical mounts and other equipment: power supplies or batteries.
A power supply provides constant voltage for an unlimited period of time. It is therefore the first choice for a stationary operation in the garden, on the patio or the balcony. However, batteries are required for mobile astronomy. These are often also called powertanks.
