Power interruptions are a fact of life in many parts of Bangladesh, and the difference between a household that copes and one that struggles often comes down to a single purchase made with a little thought. Microtek is a well-known name in power backup, and buyers searching for it are usually trying to answer one question: what do I actually need to keep the lights, fans and router running when the supply fails? The answer depends less on brand than on understanding the three kinds of backup device and matching one to your load.
Inverter, IPS and UPS are not the same thing
These three terms are used loosely in shops, so it helps to separate them. An inverter takes energy stored in a battery and converts it to run household appliances during an outage. It is designed for longer backup and larger loads, and it is normally paired with a separate battery whose capacity sets how long everything runs. An IPS, or instant power supply, is a compact all-in-one unit with a battery built in. It is simpler to install and suits a small number of lights, fans and a router, but its run time is fixed by the battery inside it. A UPS is built for a different job: it sits between the mains and a sensitive device, such as a computer or a router, and provides a short bridge of clean power so the equipment rides through a brief interruption or shuts down safely. A UPS is not meant to run a whole house.
Start by adding up the load
Before choosing anything, list what must stay on. A few lights, a fan, a television and a router is a very different demand from a fridge, a freezer or an air conditioner. Check the wattage printed on each appliance and add the figures to get a rough total, then decide which of those devices you truly need during an outage. This single step prevents the most common mistake, which is buying a unit too small for the load and discovering the problem only when the power goes out. Leave some headroom rather than sizing to the exact figure.
Think about run time and battery
Run time is a product of load and battery capacity, not a fixed number. A larger battery runs the same load for longer, while a heavier load drains any battery faster. If you need backup for several hours, plan on a larger battery or restrict the appliance list. If a short bridge is all you need, a smaller setup is enough. Batteries are a consumable part of the system; their condition affects performance and they eventually need replacing, so factor that into the long-term cost. Place the battery where it can be ventilated and kept dry.
Match the device to the job
For a home that wants lights, fans and internet to continue for a reasonable stretch, an inverter with an appropriately sized battery is usually the core of the solution, and the
inverter range shows the options to compare. For a small flat, a single room, or a budget that cannot stretch to a separate battery, an all-in-one
IPS is the simpler route, provided its built-in capacity covers your essentials. For a desktop computer, a router or other sensitive electronics that only need to survive a brief outage or shut down cleanly, a dedicated
UPS is the right tool, and it is not a substitute for whole-home backup.
Installation and safety
Power backup involves mains voltage and batteries, so it is not a casual do-it-yourself job. Use a qualified technician, size the wiring and fuses to the load, and make sure the unit is earthed properly. Do not overload sockets, keep the battery away from water and open flame, and allow ventilation around the equipment. A surge protector on sensitive devices is a sensible extra. If the system powers medical equipment, treat reliability as critical and plan a tested backup for the backup.
Before you buy
Confirm the capacity you need in watts and the backup time you expect, and ask the seller to explain how the unit behaves when the mains returns. Check whether the price includes the battery, installation and any wiring, because these can change the total significantly. Ask how the battery should be maintained, how long it is expected to last, and what replacement will cost. Compare at least two sellers and make sure the model matches the load you calculated rather than the load a salesperson estimates.
Local availability, warranty and service
Microtek power backup products are sold in Bangladesh through electronics shops, hardware stores and online sellers, with good availability in Dhaka and other large cities and thinner stock in smaller towns. Ask whether the warranty is local, how long it runs, what it covers, and where service is carried out, because a backup system is only as useful as the support behind it. Keep the invoice and warranty card, note the installation date, and follow the maintenance advice for the battery. Buy from a dealer who stocks spare parts and can service the unit locally, so a failed component does not leave your home without power for weeks.
