1. Insufficient Power Rating
Many overlook the power rating (e.g., 2500W). Overloading can cause short circuits or fires. Choose based on total device power and leave 20% headroom.
2. Missing Safety Certifications
Uncertified brands may lack international marks (e.g., CCC, UL, CE). Always prioritize certified products for safety compliance.
3. Poor Socket Design
Overcrowded or universal sockets may cause poor contact. Opt for spaced sockets, individual switches, or child-safe shutters.
4. Low-Quality Cable Material
Copper-clad aluminum wires overheat and degrade. Choose pure copper cores (labeled “100% Copper”) with ≥1.0mm² thickness.
5. No Overload Protection
Strips without overload protection can’t cut off power during surges. Choose models with fuses or auto circuit breakers.
6. Ignoring Surge Protection
Lightning strikes or voltage spikes can damage devices. For sensitive electronics, pick strips with surge protection (≥1000J).
7. Mismatched Cable Length
Too long/short cables risk tangling or strain. Select lengths (1.5m–3m) based on your space.
8. Overlooking Flame-Retardant Materials
Cheap plastic casings melt under heat. Choose flame-retardant ABS/PC (UL94 V-0 certified) with ≥1mm thickness.
9. Prioritizing Price Over Quality
Cheap strips often cut corners on safety. Balance budget and quality; avoid products priced 30% below average.
Conclusion
Power strips are critical for electrical safety. Avoid these 9 traps by choosing certified, well-designed products to protect both people and devices.
