Backup by Biolite is a giant (but sleek!) battery that keeps your fridge running during outages
Briefly

In essence, it's a large battery plus inverter that plugs into your wall. You then plug in any appliance or device you don't want to ever lose power - a fridge is a good example.
The battery is remarkably thin and the matte silver finish is about as unobtrusive as you can get. BioLite says it's designed to fade into 'forgotten places' in your home.
It's app-connected so you'll have a log of when and for how long your power goes out, and of course get notifications when things happen.
You can also use Backup on-demand when your power is perfectly fine, or even schedule it to come online at certain times, something you may want to do when you're dealing with higher electricity prices for peak usage periods.
