What wattage charger do I need for my laptop?
Ultrabooks: 45-65W is usually sufficient
Standard laptops: 65-100W recommended
Gaming/workstation laptops: 100-240W may be required. Check your laptop's original charger wattage as a baseline.
Can I use a higher wattage charger than my device needs?
Yes, it's completely safe. Your device will only draw the power it needs. A 100W charger connected to a phone that needs 25W will only deliver 25W. Higher wattage chargers often run cooler since they're not working at capacity.
What's the difference between USB-C PD, PPS, and Quick Charge?
USB-C PD (Power Delivery): The universal fast-charging standard, supports up to 240W
PPS (Programmable Power Supply): Advanced PD feature allowing precise voltage adjustment for cooler, faster charging
Quick Charge: Qualcomm's proprietary standard, primarily for Android phones with Snapdragon chips
Why does my laptop charge slowly with my phone charger?
Phone chargers are typically 18-30W, while laptops need 45-140W for optimal charging. Your laptop may charge very slowly or even drain while in use with an underpowered charger. It won't damage anything, but charging will be impractical.
What does the wattage number on my charger mean?
Wattage (W) indicates the maximum power output. Higher wattage means faster charging potential. Common ratings: 20W (phones), 30W (tablets), 45-65W (ultrabooks), 65-100W (laptops), 140W+ (gaming laptops).
Is USB-C charging safe for all devices?
Yes, USB-C Power Delivery includes negotiation protocols. Your device and charger communicate to agree on safe power levels. You cannot damage a device by using a charger with too much wattage—the device controls how much power it accepts.
