IPS vs UPS: Which One Does Your Home Need in Bangladesh? (2026)

Walk into any electronics shop in Bangladesh and ask for power backup, and the seller will ask you one question: IPS or UPS? Both keep things running when the current goes. But they are built for very different jobs, and buying the wrong one wastes money.

At home, a desktop computer is our main work machine. When the power goes, it takes about 5 minutes for the building generator to start, and every two or three months the generator does not start at all. An IPS has covered that gap for us for more than 10 years. That simple situation shows exactly where each machine fits, and where it does not.

This guide explains the difference in plain words, what each costs in Bangladesh right now, and which one your home really needs.

IPS vs UPS at a glance

	UPS	IPS
Main job	Keep a computer on for a few minutes	Run fans and lights for hours
Typical backup	About 10 to 30 minutes for one desktop	About 2 to 6 hours for fans and lights
Switch over	Very fast, a computer does not notice	Fast on most new models, older ones can be slower
Battery	Small sealed 12V batteries inside the box	Big separate battery, usually wet tubular
Battery care	No water needed	Distilled water every month or two
Price	About ৳4,000 to ৳7,500	About ৳30,000 to ৳50,000 with battery
Where it sits	Under your desk	A corner of the home, wired to the main board

What is an IPS?

IPS stands for Instant Power Supply. It is a bigger machine (called an inverter) connected to a large battery. An electrician wires it into your home so that selected fans, lights and sockets keep working when the grid power goes.

While the power is on, the IPS charges its battery. When the power goes, it turns the battery power back into normal 220V power for your home. Because the battery is big, it can run several fans and lights for hours.

• Best for: load shedding that lasts an hour or more.
• Runs: ceiling fans, LED lights, a Wi-Fi router, a TV, a laptop charger, and with a pure sine wave model, a small fridge.
• Does not run: AC, geyser, iron, induction cooker, rice cooker or room heater. These use far too much power.

What is a UPS?

UPS stands for Uninterruptible Power Supply. It is a small box that sits under your desk. Your desktop computer and monitor plug straight into it. Inside are one or two small sealed batteries.

Its main job is not long backup. Its job is to switch over so fast that your computer never turns off. A popular 1200VA model like the Apollo 1120F lists a switch time of about 2 to 5 milliseconds, far quicker than a blink.

• Best for: saving your work and shutting down safely, or bridging a short gap until a generator starts.
• Runs: one desktop computer, a monitor, a router and maybe a small printer.
• Backup: usually about 10 to 30 minutes, depending on how much power your computer uses.

There is also a costly type called an online UPS, used for servers, banks and medical machines. It powers the computer from the battery all the time, so there is no switch over at all. Most homes do not need one.

The key difference: speed vs time

The simplest way to remember it:

Many newer IPS models have a UPS mode (sometimes called computer mode) that switches faster, and many desktops survive the switch fine. But older or cheaper IPS units can be slow enough to make a desktop restart. If you lose unsaved work every time the power goes, that is the sign.

A quick test: save your work, keep the computer on, and switch off the main power. If the computer keeps running, your IPS is fast enough. If it restarts, you need a UPS for the computer.

Which one does your home need?

You only have fans and lights to worry about

Get an IPS. A UPS cannot run ceiling fans for long, and fans are what most families need during summer load shedding. If even an IPS is too much for your budget, a few rechargeable emergency lights and a rechargeable fan are a cheaper start.

You work or study on a desktop computer

Get a UPS at least. A 650VA model is enough for a basic office computer. If you have a gaming PC or a big monitor, a 1200VA model gives more breathing room. Even if your home already has an IPS, a UPS protects the computer from sudden restarts and power jumps.

Your building has a generator

A UPS alone often covers the gap until the generator starts. But generators do fail sometimes, and diesel can run out. If losing power for an hour would hurt your work, add an IPS too.

You have a desktop and long load shedding

Get both. This is the setup many Bangladeshi home offices use: the IPS powers the fans, lights and router for hours, and the desktop sits on a UPS that is plugged into a socket the IPS powers. The UPS gives instant switch over and the IPS gives long backup.

You only use a laptop

You may need neither. A laptop has its own battery. A small mini UPS for your Wi-Fi router (around ৳1,500 to ৳3,000) keeps the internet on during outages.

Cost over five years

The buying price is only part of the story. Batteries wear out, so here is a rough idea of what each costs to own.

	Desktop UPS (1200VA)	Home IPS set
Buying price	About ৳6,400 to ৳7,500	About ৳30,000 to ৳50,000
Battery	Two small sealed 12V batteries, about ৳1,450 to ৳1,650 each	One big tubular battery, about ৳18,000 to ৳34,500
Battery life	Usually 2 to 3 years	Several years with good care
Upkeep	None	Distilled water and terminal cleaning
Rough 5 year cost	About ৳10,000 to ৳14,000	About ৳35,000 to ৳70,000

If you already own an IPS, you can save the yearly service fee by looking after the battery yourself. Our IPS battery maintenance guide shows how in about 10 minutes a month.

Mistakes to avoid

• Plugging a heater, iron or kettle into a UPS. These overload it in seconds and can damage it.
• Buying a UPS for long load shedding. It will die in minutes and the small batteries will wear out quickly.
• Running a fridge on a cheap IPS. Fridges and TVs need a pure sine wave IPS. A cheaper square wave one can harm them.
• Ignoring old batteries. If your UPS beeps and dies in a minute or two, the battery is worn out. A new one costs far less than a new UPS.
• Choosing the VA number only. Check the watts too. A 1200VA UPS gives around 600 to 720 watts, which is what really matters.

How we wrote this guide

We have run a desktop computer on a home IPS in Bangladesh for more than 10 years. Prices come from Bangladeshi online shops such as Star Tech, Onix and BDStall, checked in November 2026. Prices change often, so check before you buy.
