Undeniably one of the best UPS systems available in the market today, CyberPower's CP1500PFCLCD boasts a laundry list of features.

Best for Businesses: APC UPS 2200VA Smart-UPS with SmartConnect

What We Like
  • Cloud backup

  • Extensive battery life

What We Don't Like
  • Expensive

In business, there’s no room for data loss, so it’s important to have a backup plan. The APC UPS 2200VA Smart-UPS with SmartConnect is just that. As one of the first cloud-enabled APC UPS for distributed IT systems, it's an ideal choice for businesses. IT professionals can access the hardware through a secure portal and view its status, update the firmware, and maximize performance.

Installing the hardware is a snap. Once the system is unboxed and plugged in, it connects to the network via a dedicated ethernet port. It is then automatically registered on the SmartConnect Web Portal and registered to the business. The web interface adds clear notifications to keep system administrators aware of the APC’s status. There’s also support for PowerChute software which safely shuts down the system during extended power outages. This ensures there’s no data corruption by an accidental shutdown.

Running at an average of 100 watts, the APC unit can provide over five hours and 30 minutes of battery backup. That power is available for up to 10 pieces of hardware with 10 AC outlets on the rear.

What We Like
  • Widely-spaced outlets for increased convenience

What to Look for in an Uninterrupted Power Supply

Compatibility - When buying a UPS, the most important factor to consider is its compatibility with the power supply. Before hooking anything up, check what your devices require and make sure there’s a match.

On-battery runtime - Generally, you don’t need a UPS to last too long but it should be sufficient to start a standby power source or properly shut down the protected equipment. Some run for just a few minutes, while others will provide power all night long. Depending on your needs, make sure the on-battery runtime is ample.

Device support - How many devices will you need to connect to your UPS? Some can accommodate as many as 10 devices, while others top out at just two.

Portability - Some UPS devices are crafted for home or business use, while others are built for travel and the outdoors. If you’ll need to take your device with you, you’ll want something with a more portable design that can fit in a handbag easily. You might even want a solar charging port so that you aren’t entirely dependent on electricity.
