In Iraq a power cut is a daily reality that repeats several times, and it usually arrives with a voltage disturbance the moment the grid returns or when you switch between the national supply and the generator. That repetition is the real enemy of your electronics: the PC shuts off mid-task and unsaved files are gone while the hard drive takes the hit, the router reboots and the connection drops, and the CCTV recorder goes dark at exactly the moment you need it most.
The answer is not buying the most expensive unit on the shelf. It is matching the right type of protection to the right load. This guide explains the difference between UPS types, how to actually size the capacity you need, and which unit fits each case: a small router, a desktop PC, a whole office, or a critical load that cannot tolerate a single interruption.
How to choose the right protection unit
A correct choice starts from the load, not from the price. Add up the wattage of your devices, then pick a unit that covers that figure with a safety margin. These are the points that matter:
- Unit type: A Line interactive UPS passes mains power through and corrects voltage with a built-in AVR, switching to battery within a fraction of a second. That is enough for most PCs. An Online UPS instead rebuilds the waveform continuously through double conversion, so it has no transfer time at all.
- VA versus watts: The number printed on the box, such as 1500VA, is apparent power, and the real usable power in watts is lower. On budget units the power factor is typically around 0.6, so 1500VA works out to roughly 900 real watts. Always size by watts.
- Load headroom: Do not load a unit beyond about 70% of its rating. That headroom buys you longer battery time and reduces thermal stress.
- Runtime you actually need: If the goal is to save your work and shut down safely, a few minutes is plenty. To keep the internet or the cameras alive much longer you need bigger batteries or a dedicated DC unit.
- Battery and replaceability: Most of these units run on sealed SLA batteries that wear out and get replaced, and heat is the biggest factor shortening their life. Make sure the battery for your unit is available locally.
- Display and outlets: An LCD showing incoming voltage, load percentage and battery status is a diagnostic tool, not decoration. Also check the number and type of outlets so the unit fits your setup.
Keeping the internet alive: Mini UPS GeTX GSP2
The most irritating part of short, repeated cuts is losing the internet and waiting for the router to boot every time. This compact unit is made for DC devices such as routers, modems and small switches, offering 9V, 12V, 15V and 24V outputs with PoE support, rated at 36W. It takes almost no space, runs silently with no fan, and keeps your network up through the outage.
For CCTV cameras: UPS GeTX GSCA1 DC
A security camera loses all its value the moment it stops, and that moment is usually the one that mattered. This unit is built for DC loads and provides 12V and 15V outputs, the common voltages for surveillance cameras and small network gear. Its small footprint lets you mount it right next to the recorder so coverage continues through an outage.
One PC on a tight budget: UPS GeTX GXK-850-C
The entry choice for protecting a single desktop PC with its monitor, or a point-of-sale terminal in a small shop. It is a Line interactive unit rated at 850VA with an LCD display and a single 12V 9Ah battery. Its realistic job is to give you time to save your work and shut down safely, and to shield you from voltage swings all day long.
PC and router together: UPS GeTX GXK-1000-C
A step up at 1000VA with two 12V 7Ah batteries and an LCD display. Two batteries mean longer runtime at the same load, which makes this a good fit for a desktop PC with its monitor plus the internet router on the same unit, so you stay online and finish what you were doing before shutting down.
For a small office or a stronger PC: UPS GeTX GXK-1500-C
Rated at 1500VA with two 12V 9Ah batteries and an LCD display, this unit gives comfortable headroom for a more powerful PC or two machines in a small office with the network gear. Remember the sizing rule: 1500VA means roughly 900 real watts, which comfortably covers a strong desktop with a monitor and a router, as long as you add no heating loads.
Top of the Line interactive range: UPS Gaming GeTX GTXF-3000
The most powerful Line interactive unit on this list, rated at 3000VA with four internal 12V batteries. Those four batteries give it clearly longer runtime at moderate load, so it suits a gaming PC or a workstation that draws more than average, or a corner with several devices on it.
The first step into Online: UPS GeTX GXK-1-1-1-CO 1000VA
If the mains power reaching your location is poor and swings constantly, an Online unit is the answer. This 1000VA model runs on double conversion, rebuilding the waveform from scratch so your equipment never feels a transfer during an outage, and it comes with an LCD display and two 12V 9Ah batteries. It is the most practical entry point into full protection.
For loads that cannot fail: UPS APC Easy Online SRV 3000VA
When the load is a small server, the core of a network, or lab equipment, the calculation changes. The APC Easy Online SRV at 3000VA and 230V is a double-conversion solution from a global name in power protection, designed for continuous duty rather than occasional use. It costs more, but that cost is measured against downtime and against data you cannot get back.
Common mistakes that waste the protection
Most complaints that a unit is useless come down to how it is used, not the unit itself. Avoid these six mistakes:
- Connecting the wrong loads: Laser printers, heaters and anything with a heating element draw a huge instantaneous current that trips the unit or shortens its life. Keep it to the PC, the monitor and the router.
- Sizing by VA alone: Buying a 1000VA unit for a load approaching 900W is a common arithmetic mistake that ends in a sudden shutdown the first time the system is genuinely stressed.
- Placing it somewhere hot or enclosed: Heat is the battery's worst enemy. Leave ventilation space around it and keep it away from direct sunlight and heat sources.
- Ignoring the battery until it fails: The battery is a consumable. If runtime has collapsed to a few seconds, the battery is finished and the unit itself is not the problem.
- Feeding it through a poor extension: A weak cable or a worn socket cancels the whole benefit of protection. Use a good extension and a properly earthed socket wherever possible.
- Storing it discharged for months: A sealed battery is damaged if it is left flat for a long period. If the unit is not in use, recharge it every few months.
Frequently asked questions
Does a UPS replace a generator?
No, and it is not meant to. Its job is covering short interruptions and protecting your equipment from voltage disturbance, not running a household for hours. The ideal use in Iraq is as a bridge between the grid failing and the generator starting, so your work and your network carry on through that gap.
How long will it run on battery?
Runtime depends on battery size and load percentage, not on price, and the heavier the load the more sharply the time drops. A desktop PC on a correctly sized unit typically gets enough minutes to save and shut down safely, while a small router on a DC unit can last far longer simply because it draws so little.
When do I need Online instead of Line interactive?
You need Online when the load is sensitive and cannot tolerate even a fraction of a second of interruption, or when the incoming supply is poor and unstable all day, as with servers, core network gear, and medical or laboratory equipment. For a PC, a monitor and a router, Line interactive does the job well at a far lower cost.
Can I connect a fridge or an air cooler to a UPS?
It is strongly discouraged. Motors draw several times their normal consumption at startup, which trips the unit immediately or damages it over repeated attempts. The units listed here are designed for electronic loads, not for cooling or heating appliances.
How long does the battery last and how do I know it is finished?
SLA batteries are consumables affected mainly by heat and by how often they are deeply discharged. The clearest sign of the end is runtime collapsing from minutes to seconds, or the unit raising a battery alarm while still plugged into the mains. Replacing the battery is far easier and cheaper than buying a new unit.
Does it protect against the voltage surge when power returns?
Yes, and in Iraq that is one of its most valuable functions in practice. The AVR in Line interactive units corrects high and low voltage within a defined range without touching the battery, while Online units isolate the load from the grid entirely because they rebuild the waveform. Either way, what reaches your equipment is far cleaner than what leaves the socket.
The practical takeaway
Start from a single question: what must not stop? If it is only the internet, a small DC unit is enough. If it is a PC and a monitor, choose Line interactive with capacity covering your load plus a 30% margin. And if the load is sensitive or the incoming supply is genuinely bad, move up to Online and do not compromise.
