Power Adapters Q & A
Q: What's the difference between a power adapter and a charger?
A: While often used interchangeably, adapters convert power, while chargers regulate current flow to batteries.
Q: How long do power adapters typically last?
A: Quality adapters can last 3-5 years with proper use, though industrial versions may last longer.
Q: Are universal power adapters safe?
A: Yes, if they have proper certifications and automatic voltage detection.
Q: Can I use a higher wattage adapter for my device?
A: Generally yes, as devices only draw the power they need, but voltage must match exactly.
Q: Why do some power adapters get hot?
A> Mild warmth is normal, but excessive heat may indicate poor quality or overload.
