The Amazon Basics UPS Battery Backup & Surge Protector 400VA/255 is a solid budget choice at $52.65, offering essential protection and backup for small electronics. With a rating of 4.1 stars from over 14,000 reviews, it provides reliable performance for basic needs.
When selecting a UPS, consider the total wattage of the devices you plan to connect.

Key features to look for include surge protection, battery capacity (VA rating), and the number of outlets. The APC UPS models often include additional features like LCD displays for monitoring battery status, which can be very helpful in managing power efficiently.
APC generally has a strong reputation for reliability, as seen in the APC UPS Battery Backup with 4.5 stars from over 36,000 reviews. CyberPower also offers competitive models with decent ratings, but some users find APC's customer support to be superior, making it a preferred choice for many.
The lifespan of a UPS battery typically ranges from 3 to 5 years, depending on usage and maintenance. To extend battery life, regularly test the UPS, keep it in a cool environment, and replace the battery as recommended by the manufacturer, especially if you notice reduced backup time.
When budgeting for a UPS, consider both the upfront cost and the potential long-term costs of battery replacements. Prices range from around $21.69 for basic models to up to $299.99 for more advanced systems, so assess your power needs and select a model that balances cost with necessary features.
