Real products, live prices, in stock now ## Key takeaways - Damage often happens when power returns. - Fridges and freezers need a delay-start protector. - Surge protectors guard electronics against spikes. - Stabilisers fix constantly low or high voltage. - Businesses should add surge protection at the board. ## Quick checks you can do first 1. **Notice the pattern**: Dimming lights mean low voltage; blown power supplies after outages mean surges. 2. **Protect fridges**: Plug them into a voltage protector with a startup delay. 3. **Protect electronics**: TVs, routers and PCs on surge protectors or a UPS. 4. **Measure**: An electrician can log voltage to see how bad it is. 5. **Report to KPLC**: Persistent low or high voltage is a supply issue to report. **Important**: Switch off and isolate power before opening any equipment. Batteries, inverters and mains wiring can cause serious injury; leave internal work to a qualified technician. ## What usually causes it | Symptom | Likely cause | Fix | | --- | --- | --- | | Fridge stops after outages | Restart surge | Delay-start voltage protector | | Router/PC power supplies die | Spikes | Surge protector or UPS | | Lights dim, motors struggle | Low voltage | AVR stabiliser | | Damage after storms | Lightning surges | Board-level SPD, earthing | | Whole area affected | KPLC supply fault | Report to Kenya Power | ## When to call a technician - Equipment keeps getting damaged. - You run CCTV, servers or POS on site. - You need board-level surge protection or earthing checks. - You want a stabiliser sized for the building. **When to call a professional**: Qyvea technicians diagnose and fix this on site across Nairobi and Kenya.

If your area has frequent outages and surges, yes. It delays restart until voltage settles. What's the difference between a surge protector and a stabiliser? A surge protector blocks short spikes; a stabiliser corrects voltage that's constantly too low or high. Does a UPS protect computers? Yes. A good UPS conditions power and rides through short dips. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
