Travel Adapter and Power Bank Guide for International Trips
Two small gadgets keep everything else running: the right travel adapter and a capable power bank. Here’s how to choose ones that actually work where you’re going.
Plug types and voltage
Check the plug type and voltage for your destination. Modern devices like phones and laptops usually handle 100–240V, but others such as hairdryers may not.
Choosing a universal adapter
A universal adapter with built-in USB ports covers most countries and charges several devices at once. Pick a compact, sturdy one rather than the cheapest.
Choosing a power bank
Choose a power bank within airline limits (generally under 100Wh) and always carry it in your hand luggage, never checked. Around 10,000–20,000mAh suits most trips.
What to skip
Skip single-country adapters and oversized power banks above airline limits. You usually don’t need a voltage converter if your devices are dual-voltage.

FAQ
Can I take a power bank on a plane?
Yes, in your carry-on within the airline’s watt-hour limit — power banks are not allowed in checked luggage.
Do I need a voltage converter?
Usually not for phones and laptops (they’re dual-voltage); you may for high-wattage items like hairdryers — check the label for "100–240V".
