Customers are saying

Customers admire the 1000VA Battery Back-Up System for its exceptional battery life, overall performance, ease of use, and surge protection capabilities. Many appreciate its compact size, reasonable price, and the abundance of outlets it offers. While some users have noted that the device can be a bit noisy when activated and slightly heavy, and that the instructions could be clearer, the positive aspects appear to outweigh these concerns.

This summary was generated by AI based on customer reviews.

The vast majority of our reviews come from verified purchases. Reviews from customers may include My Best Buy members, employees, and Tech Insider Network members (as tagged). Select reviewers may receive discounted products, promotional considerations or entries into drawings for honest, helpful reviews.

    Provides excellent backup power to my system. The older unit it replaced was not up to the task and had failed far too soon.

    I live in an environment that has a very shaky electrical grid. This product is perfect for that because it keeps my electronics powered on during blackouts and brownouts.

    Works amazing! Not that bulky and adds comfort knowing that office computer, printer, WiFi routers & hard drives have power protection so when power goes out.

    My smaller unit was having problems with laser printer startup -- switched to battery and did not recover. So far this larger unit has not repeated the problem.

    I bought this battery backup after researching online and finally decided on this model based on recommendation from a Best Buy sales associate. It may be bigger than I need but rather too big than too small.

    Initially bought a lower VA backup- didn't cut it. This one did the trick - my psp pushes 500w even more under load, good interface to manage from the desktop (USB cable included). Definitely lives up to the standard.
