Electricity is essential in every home, but it also comes with risks, especially when it comes to protecting your appliances. Sudden or unstable power can damage expensive gadgets and home appliances like TVs, air conditioners, etc., making surge protectors and stabilizers important. But which one should you get? Do you need both?
This guide explains the uses, types, and pros and cons of these household appliances, helping you understand their key differences and which is best for your home.
What is a Surge Protector?
A surge protector is a device that protects electronics from sudden spikes in voltage (also known as power surges). These surges can occur for various reasons, including lightning strikes, faulty wiring, when high-power appliances (like air conditioners) turn on and off, or when the light voltage suddenly increases.
A surge protector acts like a gatekeeper. Under normal conditions, it allows electricity to pass through safely to your devices. But if a sudden voltage spike occurs, it redirects the excess power away, preventing it from reaching and damaging your appliances.
When Should You Use a Surge Protector?
Surge protectors are best for:
Sensitive electronics like computers, TVs, gaming consoles, and home theater systems.
Office equipment such as printers, routers, and modems.
Small kitchen appliances like microwaves and coffee makers.
Types of Surge Protectors
1. Basic Power Strip Surge Protectors
These look like regular extension cords but come with built-in surge protection. They allow you to plug in multiple devices while shielding them from voltage spikes. However, they offer limited protection and are best suited for low-power devices like lamps, phone chargers, and small appliances. They are best for TVs, desktop computers, routers, and other basic household electronics.
Example:
Belkin 6-Outlet Surge Protector – This is a budget-friendly option with six outlets and a 600-joule rating, making it great for home use.

4. Uninterruptible Power Supply (UPS) with Surge Protection
A UPS protects against power surges and provides backup power. If there’s an outage, your devices will stay on for a few minutes, giving you time to save work or safely shut down appliances. This is especially useful for computers, servers, and security systems. It is best for offices, gaming PCs, medical equipment, and businesses that rely on power.
Example:
CyberPower CP1500AVRLCD UPS—This model offers surge protection and battery backup, making it ideal for gaming PCs and home offices.

Pros
Prevents damage from power surges – Keeps your electronics safe from voltage spikes.
Affordable – A basic surge protector is relatively inexpensive.
Easy to install – Plug it into an outlet and connect your devices.
Protects multiple devices at once – Most models come with multiple outlets.
Cons
A surge protector doesn’t regulate voltage; it only protects against sudden spikes. However, it won’t help if your electricity fluctuates frequently.
Surge protectors wear out over time and must be replaced after a few years or a major power surge.
What is a Stabilizer?
A stabilizer, also called a voltage regulator, is designed to maintain a steady voltage level for your appliances. Instead of just blocking power surges, a stabilizer ensures that your devices receive a stable voltage, even when the electricity supply fluctuates.
A stabilizer constantly monitors the voltage coming from your power supply. If it's too high, it reduces it. If it’s too low, it boosts it to the correct level. This prevents your appliances from getting damaged due to low or high voltage fluctuations.
When Should You Use a Stabilizer?
Stabilizers are best for:
Large home appliances like refrigerators, air conditioners, and washing machines.
Sensitive devices like desktop computers and home theater systems.
Areas with unstable electricity – A stabiliser is a must if you live where voltage often fluctuates.
Types of Stabilizers
1. Relay-Type Stabilizers
These are the most common and affordable stabilizers. They use relays (electronic switches) to adjust voltage levels when they go too high or too low. However, they respond slowly, which means brief voltage fluctuations might still affect your appliances before the stabilizer reacts. They are best for small home appliances like TVs, refrigerators, and air conditioners.
Example:
Bluebird Voltage Stabilizer for Refrigerators – A basic, reliable stabilizer designed to protect your fridge from voltage fluctuations.
Price: NGN 52,699.00 Where to buy: Jumia
2. Servo Motor Stabilizers
These offer more precise voltage control compared to relay stabilizers. They use a servo motor to adjust the voltage smoothly instead of switching abruptly. This means they react faster and provide better protection, especially for sensitive electronics. They are ideal for medical equipment, industrial machinery, and high-end home appliances.
Example:
V-Guard VG 400 Stabilizer – A high-performance stabilizer known for smooth voltage regulation, commonly used for ACs and home appliances.
Price: NGN 54,855.00 Where to buy: Ubuy
3. Static Voltage Stabilizers (SVS)
This is a more advanced type of stabilizer that uses electronic circuits instead of mechanical components. Because there are no moving parts, it responds instantly to voltage fluctuations, making it the most efficient stabilizer. It is best for critical equipment like servers, data centers, and hospitals, where even the smallest power fluctuation can cause problems.
Example:
5KVA Relay XTRA Power Voltage Stabilizer (95-280V) – A high-efficiency stabilizer commonly used for sensitive electrical equipment. Price: NGN 299,400.00 Where to buy: Prag
4. Automatic Voltage Regulators (AVR)
An AVR is a smart stabilizer continuously monitoring voltage and making real-time adjustments. It’s commonly found in home inverter systems and UPS units to provide stable power for computers, TVs, and other electronics. AVRs are most suitable for home power backup systems, computers, and sensitive electrical appliances.
Example:
APC Line-R 1200VA Automatic Voltage Regulator – A well-known AVR used for computers, gaming consoles, and home office setups.
Price: NGN 25,000.00 Where to buy: Tiaco Technologies
Pros of a Stabilizer
Prevents voltage fluctuations – Ensures that your appliances always receive the correct voltage.
Prolongs appliance lifespan – Protects sensitive components from voltage-related damage.
Essential for areas with unstable power supply – A stabilizer is necessary if your electricity is unreliable.
Cons of a Stabilizer
It does not protect against sudden power surges. Unlike a surge protector, a stabilizer won’t help if there’s a lightning strike or a sudden spike in electricity.
More expensive than surge protectors – Good stabilizers can cost significantly more than basic surge protectors.
Bulky and requires installation – Unlike plug-and-play surge protectors, stabilizers need proper setup.
Which One Should You Buy?
A surge protector is a great starting point if you’re on a budget and only want basic protection for your gadgets. However, if you live in an area with unstable electricity, investing in a stabilizer for major appliances is a smart move.
For complete protection, using both is the best approach. A surge protector will handle sudden spikes, while a stabilizer will regulate fluctuating voltage—keeping your home and appliances safe in any situation.
Electricity can be unpredictable, but you mustn’t leave your appliances unprotected. Surge protectors and stabilizers serve different purposes, and choosing the right one depends on your home’s power situation. If you experience sudden spikes, a surge protector is enough. But if your electricity is unstable, a stabilizer is a must. And if you want the best possible protection, using both together will give you peace of mind.
So, what’s the best choice for your home? If you’re still unsure, look at your appliances and consider what power problems you often face. A little investment in protection today can save you from costly repairs or replacements in the future!
