The Hormann ProMatic Akku is a convenient solution for garages without a power connection. 

The portable battery supplies the operator with power and can be charged inside the house via a normal power socket in a matter of hours. 

If this is of interest, you should also enquire about the ProMatic Akku Solar Module which includes a solar panel, making charging the battery even more convenient.
