Walk into any electronics market and the shopkeeper will sell you a stabilizer. But is it the right one? Probably not. Here is how to choose correctly.
First, check the input range
Most stabilizers only work from 170V and above. But in Lahore and Karachi, voltage often drops below 150V in the evening. A stabilizer that cannot handle low voltage is useless at the time you need it most. Always ask: "kitne volt tak kaam karta hai?" The answer should be 140V or lower.
Second, match the size to your load
- 1 AC + fridge + lights: 5 kVA stabilizer
- 2 ACs + fridge + other appliances: 10 kVA stabilizer
- Whole house: 15 kVA stabilizer
If your electrician says "bari wali le lo" without checking your load, get a second opinion. Oversized stabilizers waste electricity and cost more.
Servo or relay? Always pick servo.
Relay-type stabilizers are cheap but they correct voltage in jumps. This is bad for your AC compressor. Servo-type stabilizers — like ours — correct smoothly. Your AC runs cooler and lasts longer.
Warranty check
Always ask what the warranty actually covers and who services it locally if something goes wrong. Get it in writing before you buy.
