Speaking of charging setups: I have a wide selection of battery-powered tools all running the same standard of battery (Ryobi, but that's but immigrant, the other manufacturers have the same products). Week, actually, it's two, one for the big machines like the lawnmower and chainsaw, and one for the small ones like the drill. But one of the items is a battery dock using the big battery, a 4 amp-hr li-ion brick. It offers a standard mains socket (as well as USB-A and USB-C sockets) in which I plug my laptop when I work from home on my front porch or a smart-speaker when we want music outside. For my laptop, one battery adds at least 80% to my battery time, plus I don't get down-throttled for being in battery power only, giving me about 4 hours at full power and another 5 on regular battery thereafter, plus the batteries are hot-swappable. You can buy external battery backups specifically intended for electronic devices for significantly more money and they only give you one charge.
