APC (BE850G2-UK)

Power Supply That Has it All

The APC BE850G2 is a slightly smaller UPS unit compared to other products included on our list but its compact size doesn’t diminish its capabilities.

To start things off, the appliance features 8 IEC-C13 power outlets with 6 of them having surge protection. In addition to that, it has two USB power ports (Type-A and Type-C) that can be used to charge smaller USB-powered devices. Similarly to other models on the list, the BE850G2 has an analogue RJ45 port for a telephone line, as well as an RJ45 LAN network cable outlet.

As a means of displaying the current status of the internal battery and the connected devices, the UPS unit has a set of bright LED lights that will conveniently show you the charge levels with 25% increments. The only real drawback of the BE850G2 is its charging time. To be more precise, it can take up to 16 hours to fully charge the internal battery of the appliance, which coupled with its relatively low wattage output doesn’t make the whole kit particularly outstanding. That being said, the power supply has its uses, especially for smaller server rooms and workstations that don’t carry a lot of data that needs protection.

On the bright side, however, once the battery is fully charged the power draw of the appliance is minimal and won’t exceed 2 watts per hour, which is much lower compared to more capacious alternatives.

Review of APC (BE850G2-UK) 850VA Uninterruptible Power Supply

Not As Simple As It Looks

Speaking of capacity, we couldn’t let the battery capacity be omitted. Under its plastic housing panels, the device has a replaceable RBC17 battery that has a capacity of 850 VA. Moreover, this rather compact appliance can deliver up to 520 watts of power in total, which makes it a decent option for the price.

The variety of different UPS devices from APC can be quite staggering at first, however, each one of these models is designed for specific purposes or to support certain hardware and types of electronic appliances. This model, for example, is able to accommodate multiple computers, laptops, monitors, and even a couple of smaller gadgets like phones and tablets simultaneously.

To wrap things up, the BE850G2 will be a good option for users looking for a high-quality uninterruptible power supply that will operate flawlessly and won’t break the bank at the same time. Reasonably compact and quite portable, it won’t take a lot of space on your working desk or in the server room but will prove to be an irreplaceable piece of hardware, especially when it comes to protecting data and internet connection during power surges.

Digital and Other Capabilities

As for the software included in the box, it is quite convenient to use and actually brings a lot of benefits to the users that utilise it on a regular basis. The program enables monitoring the voltage and wattage values in real-time and ultimately control the power supply of the connected devices remotely.

The only gripe we have about this model, though, is its audible alarm system that is a bit too loud. That said, since it’s an alarm, there’s less of a chance you will miss the audible cue in case of an emergency so it’s not really that big of a problem.

Furthermore, the runtime of the battery is 6 minutes at half capacity and 1 minute when capacity is maxed out, which should give you some time to turn off the hardware properly. Moreover, the integrated software support enables using the desktop application to turn off the connected devices automatically, which is a neat little feature.

All things considered, the Cyberpower BR1000ELCD will be a great pick for users that need a reliable power source that is not afraid of sudden power surges or complete outages. Its internal battery is plenty capacious while its excellent protection systems alongside an automatic voltage regulator will ensure that no hardware components get damaged in case of a short circuit on the line.

APC (BX700UI)

Surprising Capacity

This particular APC power supply is slightly different from the other products from the company but not solely because of its design. On the contrary, the main aspect that separates the BX700UI from the regular crowd is its power transfer time. To elaborate on that, the 4 ms transfer time is a remarkable improvement over the standard 8-10 ms values that are common in bigger APC power supply units.

Since this model is a line-interactive one, it is required to be connected to a mains power socket in order to run properly. Once powered, it will take around 8 hours to fully charge the internal battery, which is almost as twice as fast as some other premium UPS products.

Moving down the list of features, it is important to not omit the actual runtime of the integrated battery. With up to 8 minutes of runtime when loaded at 50% of the total power capacity, it will be more than enough to switch off all the hardware and electronics connected to the UPS. As for the actual number of active connections, the appliance has 4 IEC-C13 sockets that are compatible with all 3-prong UK power plugs. Once the devices are connected to the power supply they will be backed up with a battery, given that it has been fully charged beforehand.

Capacity-wise, the appliance utilises a 700 VA battery, which combined with a relatively short charging time makes the BX700UI a good compromise between bulky high-capacity power supplies and tiny yet low-power units. Although the actual runtime is rather short, the total power output rated at 390 watts will be sufficient to keep high-powered computers, laptops, and gaming consoles running just enough for you to switch to an alternative power source or to stop their operation properly in a safe mode.

In order to bring more convenience to the table, the BX700UI can be hooked up to a computer via a provided USB cable. When connected, you can use the PowerChute software that enables automatic shutdown of all connected hardware in a safe manner. Likewise, the program allows monitoring the voltage of the power grid and all the components connected to the UPS in real-time.

To sum things up, the BX700UI will be an excellent entry-level for users that are still on the fence about the idea of having an uninterruptible power supply at home. It is surprisingly simple to use, it has great protection against voltage surges, and it provides enough power to safely shut down all the connected appliances, and all in all - there’s not much more you could ask from a budget-friendly UPS.

What Is an Uninterruptible Power Supply?

Most modern houses are stuffed with electrical devices. They all add to our life’s convenience, but electronic equipment is very sensitive to an unstable line voltage and power surges. The perfect solution is an uninterruptible power supply (UPS) that can protect the vulnerable electronics as well as give you enough time to shut them down in a proper way. 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, all-in-one desktops and many other devices such as gaming consoles and laptops. In this review, we will help you pick the one your house or office needs to keep the hardware protected in case of a sudden voltage surge or even during complete power cuts.

In order to keep all the small gadgets powered in case of a major power cut, we also recommend taking a look at the best power banks that are available on the market. Perfect for home use as well as on the go, they will ensure that your phones and tablets are juiced up and ready to use at any given time.

What Features to Compare

UPS Type

The first tip we'd like to offer is, while choosing and purchasing an uninterruptible power supply, 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 stabilisation function. It means that in the case of voltage fluctuations the UPS stabilises a voltage using a transformer without any battery backup. If it is impossible to stabilise the voltage deviations during a power failure, the line-interactive UPS switches to a battery power supply in 3-4 milliseconds.

Battery Characteristics

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 how much energy would 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, a PC with components of average parameters. UPS with 500-1000 VA power supply will feed game computers, 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 your electronics with up to 15 minutes working 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, a computer network. Each interface has input and output connectors. In between them, there is a filter correcting high-voltage interferences. You can connect a router to a USP via a network cable. The most modern uninterruptible power supplies support data transmission to your computer through a USB or a COM port. Thus, a UPS gives you essential data on battery backup condition and charging, on electric 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 specific software for 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 a minimum of 2 years. Usually, UPS have both surge and battery backup outlets. You can use the former for appliances that need surge protection only. They will not affect a battery backup power, which will extend the battery useful life; the devices with more outlets of this kind are preferable.
