Features

It has a dashboard that turns on when I tap it and it tells you what is going on with your house current at that outlet, volts, cycles in and out and reserve time available at the current load and charge level.

Key Specs

This is exactly what I needed. A good, reliable battery and line conditioner for my Desktop computer (Gaming power here). I only pull 150 watts while net surfing and posting this.

Power

I've got two 27" monitors, my computer tower, an external hard drive, and plenty of peripheral attachments plugged into the unit and it handles everything just fine normally. Currently as I write this, the UPS load is reading about 84 watts and has an estimated battery runtime of 46 minutes.
 

APC BE850G2

Protect Your Devices

Your PC deserves much better than the power outages or voltage fluctuations. To save the day for your home or office electronics, consider getting the APC battery backup. With 9 outlets, it does a great job of keeping the power up and stable in case of failure or emergency.

This 850VA / 450W backup is compatible with your PC, wireless routers, gaming systems such as consoles, and TVs/DVR. Its primary function is to give your device the energy when there is an outage and prevent the damage from sudden turnoffs. Make sure your docs and application processes don’t shut down on you in the worst possible moment. The only thing to take note of is that the back-up won’t be quite good enough for a high end gaming system.

As for the outlets, you get 6 UPS battery backup / surge protection ones, as well as 3 that are surge protection only. It’s up to you what to connect to this backup, from a printer to a router. Stop depending on the maintenance of your network and give yourself the time to normally shut down your processes. And if you need to power up your phone, there are 2 handy USB charger ports.

Review of APC BE850G2 UPS Battery Backup and Surge Protector

Easy Installation

The APC backup is not only practical, but also user-centric. The 5' power cord will be enough for placing the device on the desktop without all the fuss. It’s stable enough and shouldn’t get overturned if you accidentally pull on a wire. The backup comes with a 3-prong wall plug, and the wall mounting option is great if you’re really pressed for space.

Is this unit difficult to install? Actually, it’s pretty easy, even if you haven’t done it before. Install the battery, plug it in, wait for the charging indicator light, and connect your electronic devices. That’s all; no complex setup or tech skills required other than following the manufacturer’s instructions.

This backup includes an alarm system that’s flexible enough to fit in with your daily routine. You can mute it for some time by pressing the power button for 1-2 seconds – or set up the hours in which it will be disabled. The only downside to this otherwise useful feature is that the alarm signal can be a bit too annoying.

Overall, the APC battery backup is what you need to keep your home or office electronics up and running during power emergencies.

What Is an Uninterruptible Power Supply (UPS)?

Most modern houses are stuffed with electrical devices. They all add to our convenience and it is hard to imagine our life without them. However, electronic equipment is very sensitive to an unstable line voltage and power surges. The perfect solution to this issue is an uninterruptible power supply (UPS).

This device has a powerful battery backup to provide your electronics with temporary power supply and save all the important data on your computer if utility power fails. The UPS will secure your gaming PCs, computer monitors, 3D TVs and smart TVs, all-in-one desktops, and many other devices, which will help prolong their service life and prevent unwanted failures. Thus, by purchasing a reliable battery backup for your electronics, you will save not only your money and your time but also your peace of mind.

In our review, we have selected 5 best uninterruptible power supplies available on the market and summed up some useful tips on how to choose a perfect device for your needs.

What Features to Compare

UPS Type

When choosing an uninterruptible power supply, first take a look at the UPS type. Today, there are two main types on the market: standby and line-interactive. The standby UPS is used to feed the plugged electrical appliances or recharge a flat battery (when the line voltage is satisfactory). During voltage interruptions or deviations, the device assures a battery backup. As for the line-interactive UPSs, they have an additional voltage stabilization function. This means that in the case of voltage fluctuations the UPS stabilizes a voltage using a transformer without any battery backup. If it is impossible to stabilize the voltage deviations during a power failure, the line-interactive UPS switches to a battery power supply in 3-4 milliseconds.

Battery

The next thing you should keep in mind when choosing a UPS is battery characteristics. Firstly, consider the battery capacity measured in volt-amperes (VA) or Watts (W). Secondly, the UPS should have a 20% to 30% higher capacity than that of the electronics to be plugged in. To select an appliance with the appropriate power supply, you should calculate the average amount of energy that is required to feed all the appliances you are going to connect to an uninterruptable power supply. For example, a 350-500 VA capacity would suffice for an LCD monitor or a regular PC. UPSs that use batteries with a 500-1000 VA capacity will feed gaming computers and high-power computers with two monitors. Uninterruptible power supplies with a capacity higher than 1000 VA will let you protect additional peripheral units. Another important characteristic is UPS wireless productivity. A standard UPS in household use provides up to 15 minutes of working time under peak load conditions. This time is quite enough to save all your data and shut down your computer properly. Uninterruptible power supplies with reliable lead-acid batteries have a rather short recharge time, about 8 hours.

Power Surge Protection

One more important point in choosing a UPS is its power surge protection. In addition to a no-break power supply, modern devices provide efficient data line protection - for example, a telephone, computer network, etc. Each interface has input and output connectors and between them, there is a filter correcting high-voltage interferences. You can connect a router to a USP via a network cable. Most modern uninterruptible power supplies support data transmission to your computer through a USB or a COM port. Thus, a UPS provides information on the battery backup condition and charging as well as on the network performance; informs you if the UPS turns to a wireless power supply; properly shuts down the PC while you're away; saves all the open app data in case of a power surge or fault. You can monitor and adjust the device performance from your computer. UPS manufacturers usually supply special software to enable this option.

Extras

The last important tip for selecting a UPS is to look through its extras. Contemporary devices have displays for monitoring UPS performance. As for the low-budget uninterruptible power supplies, LED indicators usually inform you about the device operation. Sophisticated models feature an LCD display with the detailed information on a USP condition and its performance, as well as an audible alarm. A quick UPS power battery replacement will add to your device's convenience. As a rule, the battery serves for 2–4 years depending on how often the battery backup is required. A replaceable device battery will prolong your UPS service life for at least 2 years. Usually, UPSs have both surge and battery backup outlets. You can use the former for appliances that need surge protection only. They will not affect battery backup power, which will extend the battery's useful life; the devices with more outlets of this kind are preferable.
