よくある質問
How do I know the power output my device needs?
Check your device’s power adapter or manual for input requirements. You’ll find voltage (V) and current (あ) 仕様. Multiply these numbers to determine required watts. Most devices also list power needs directly on their chargers.
Can I use a higher power output than my device needs?
はい, it’s generally safe as long as the voltage matches. Modern devices are designed to draw only the power they need. 例えば, a 100W charger can safely power a 60W laptop, as the device controls power draw.
What happens if I use a lower power output?
The device will charge slower or may not work at all. 例えば, a 30W charger won’t properly power a 60W laptop. Some devices might show a “slow charging” warning or won’t turn on.
Can using the wrong power output damage my device?
Wrong voltage can damage your device, but incorrect amperage usually won’t. Always match voltage specifications exactly. Modern devices have protection circuits, but it’s better to be safe.
Are all USB-C ports the same?
いいえ. USB-C ports can deliver different power levels and speeds. Some support Power Delivery (PD) up to 240W, while others might only handle basic charging. Look for specific power ratings on ports.
What’s the difference between mAh and Wh?
mAh (milliamp-hours) measures charge capacity, while Wh (ワット時間) measures energy capacity. Wh = (mAh × V) ÷ 1000. Wh is a more accurate indicator of a battery’s energy storage, as it includes both voltage and capacity.
