Can I put my laptop in checked luggage?

No. Laptops and tablets contain lithium batteries, which are fire risks in cargo holds. Plus, checked bags are handled roughly; your laptop is highly likely to be damaged.

Do I need a voltage converter for my phone charger?

Probably not. Most modern phone and laptop chargers are 'dual voltage' (100-240V). Check the small print on your brick; if it says 100-240V, you only need a plug adapter.

What is the rule for power banks on planes?

Airlines restrict lithium-ion batteries. Most carriers allow power banks up to 100Wh (roughly 20,000mAh) in carry-on bags only. Never put these in checked luggage.

How to Pack Electronics for International Travel

Protect your electronics by using hard-shell cases, keeping all devices in your carry-on to prevent damage or theft, and packing universal power adapters that match your destination's plug types. Never check lithium-ion batteries in your luggage as they are a fire hazard and restricted by airlines.

Inventory and power check. List every device you are bringing. For each, verify you have the correct charging cable and a wall brick that handles the local voltage (check if it says 'Input: 100-240V'). If it only says '110V', you will need a voltage converter, not just a plug adapter.
Choose your adapter. Buy one high-quality, universal travel adapter that covers Type A, C, G, and I plugs. Avoid cheap, multi-piece kits that fall apart; look for one with built-in USB-C and USB-A ports to save space.
Organize cables and small items. Use a dedicated tech pouch with elastic loops. Coil cables using the 'over-under' method to prevent wire breakage and store them alongside a small power bank (under 20,000mAh for airline compliance) and earbuds.
Protect your hardware. Place laptops and tablets in dedicated sleeves. If you don't have a padded backpack, wrap these devices in a thick fleece layer or sweater within your carry-on to absorb shocks from overhead bins.
Prepare for security screening. Pack your electronics so they are easily accessible in one pocket of your bag. You will likely be asked to pull out large items (laptops, cameras, iPads) at security checkpoints; having them in one place speeds up the process.
