I second this. A more powerful 12V socket adapter is far better than a battery pack.

Many of the younger generations seem to accept that things don’t last/break easily. I come from a time where there was a wiring diagram for the TV pasted on the inside back cover. Washing machines and other devices often had the schematics included. Repairing your stuff and keeping it running was the norm back then. Even if you couldn’t, you probably had a neighbour who could. Planned obsolescence is a relatively new thing.
