Published 2026-11-01 · Updated 2026-11-01 · Tech & Apps, [skoop.news](https://skoop.news/) ## In brief - The Backup by BioLite starts at $2,000, and homeowners can install it themselves. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) [[2]](https://www.wired.com/review/backup-by-biolite/) - No special wiring is required. [[2]](https://www.wired.com/review/backup-by-biolite/) - BioLite promised a 30-minute installation. [[2]](https://www.wired.com/review/backup-by-biolite/) ## A fridge battery you install yourself The Backup by BioLite starts at $2,000, and homeowners can install it themselves. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) [[2]](https://www.wired.com/review/backup-by-biolite/) BioLite is on the cusp of launching it as an alternative to whole-house batteries. [[2]](https://www.wired.com/review/backup-by-biolite/) It targets one problem: a power outage is a nuisance, and losing power to a refrigerator spoils the food inside it. [[2]](https://www.wired.com/review/backup-by-biolite/) The Backup is a modular battery system designed specifically for the fridge. [[2]](https://www.wired.com/review/backup-by-biolite/) ## How it connects and what it includes No special wiring is required. [[2]](https://www.wired.com/review/backup-by-biolite/) You plug the Backup into a standard 120-volt outlet, then plug the refrigerator into the Backup. [[2]](https://www.wired.com/review/backup-by-biolite/) The Backup is slender and designed to sit on top of a refrigerator or be mounted on a wall behind or near it. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) It includes a Power Hub that adds three AC outlets and four USB ports, two USB-A and two USB-C. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) It carries three UL certifications covering its uninterruptible power supply, battery safety, and battery cells (UL1778, UL1973, UL1642). [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) ## Installation: 30 minutes promised, 90 taken BioLite promised a 30-minute installation. [[2]](https://www.wired.com/review/backup-by-biolite/) The reviewer's own installation of the Backup Complete took about 90 minutes. [[2]](https://www.wired.com/review/backup-by-biolite/) Two details slowed things down. The two batteries in a Backup Complete must be placed at a specific distance from one another because the connecting cable is limited in length. [[2]](https://www.wired.com/review/backup-by-biolite/) The mounting template also lacked enough side buffer space, and the Core battery's outlets on its right side need additional room to plug in and scan the QR code. [[2]](https://www.wired.com/review/backup-by-biolite/) BioLite endorses placing the batteries on top of the fridge instead of using the wall mount. [[2]](https://www.wired.com/review/backup-by-biolite/) The reviewer said that would save time and make the units easier to move. [[2]](https://www.wired.com/review/backup-by-biolite/) ## Runtime in the app The app's runtime estimate accounts for the refrigerator's average draw. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) At one point it showed about 12 hours remaining, which the reviewer said was close to true. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) ## What it means for you If you want fridge-only backup power, the Backup starts at $2,000 and you can install it yourself. [[1]](https://www.popularmechanics.com/home/a73867610/refrigerator-backup-by-biolite-review/) [[2]](https://www.wired.com/review/backup-by-biolite/) It plugs into a standard 120-volt outlet, so no special wiring is required. [[2]](https://www.wired.com/review/backup-by-biolite/) If you buy the Backup Complete, plan for more than the promised 30 minutes, since the reviewer's install took about 90. [[2]](https://www.wired.com/review/backup-by-biolite/) Check the spacing between the two batteries, because the connecting cable is limited in length. [[2]](https://www.wired.com/review/backup-by-biolite/) Leave a few extra inches beside the Core battery for its right-side outlets. [[2]](https://www.wired.com/review/backup-by-biolite/) Setting the batteries on top of the fridge is the option BioLite endorses, and the reviewer said it would save time.
