One Adapter for Laptop, Phone, and Earbuds
The most frustrating moment abroad is realizing at midnight that your charger doesn't fit the wall. Modern universal adapters with USB-C PD (Power Delivery) 65 W charge a laptop, phone, tablet, and earbuds simultaneously from a single socket.
What to Check Before Buying
1. Plug types — cover all six Look for coverage of Type A (US, Japan), B (grounded US), C (most of Europe), G (UK, HK, Singapore), I (Australia, NZ, China), and L (Italy, Chile).
2. Voltage — 100–240 V required An adapter changes plug shape only — it does not convert voltage. Your charger or laptop brick must say "Input: 100–240 V" to work safely on 220 V mains. Single-voltage devices (old hair dryers, shavers) need a separate transformer.
3. USB-C PD 65 W minimum for laptops USB-C PD at 65 W is the laptop charging standard. Below 45 W, a MacBook Pro or gaming laptop trickle-charges. USB-A ports should support QC 3.0 (18 W) for fast phone charging.
4. Multi-outlet vs. single Single adapters pocket easily. But if your hotel has only one wall socket, a multi-outlet adapter with 2–3 AC plugs plus USB ports is far more practical.

FAQ
Q. Adapter vs. voltage converter — what's the difference? An adapter changes plug shape only. A converter changes voltage (e.g. 220 V → 110 V). Modern laptop and phone chargers are dual-voltage, so an adapter is enough. Older single-voltage appliances still need a separate converter.
Q. Can 30 W USB-C PD charge a laptop? MacBook Air and Chromebooks charge fine at 30 W. MacBook Pro 14/16 and gaming laptops need 65 W or more.
Q. Should I buy at the airport? Only as a last resort — airport pricing is 2–3× retail. Order before you leave.
