If you have important electronics that have to keep running when the power's out, you'll need an uninterruptible power supply (UPS). We've reviewed our recommendations and are confident these are still the best UPS devices you can buy. Many smart devices have built-in battery packs, with modern laptops packing enough cells to last a whole day.

The APC BR1500G Backup Battery is made even more special by its ability to hook up to an external battery backup to double the power. This could be useful if you connect more devices or need to power existing appliances for longer. Plus, if the battery runs out, you can replace it easily.
