Packing for international travel gets simpler when you start with a clear checklist of accessories that affect your daily comfort and your ability to navigate. This guide covers the essentials most travelers need before a trip abroad: power adapters, travel documents, money, and connectivity. You will also find guidance on checking official travel advisories so you can prepare for entry requirements and safety conditions ahead of time.

Before you start

Begin with official travel advisory pages for your destination. Advisory levels can change because of safety conditions, health requirements, entry rules, or local events, so rely on the current official page rather than a travel forum summary. Also check the destination embassy or consulate website for visa, vaccination, and passport rules, and confirm any airline-specific policies for baggage and carry-on items.

A useful habit is to gather your documents in one place before packing. If you need help deciding what kind of bag will work best, our guide to choosing luggage for international flights explains how to match a suitcase, backpack, or carry-on to your itinerary.

The checklist, grouped by category

Power adapters and charging gear

The power adapter is the first item most people think of, and it is often the one that causes confusion. An adapter only changes the shape of your plug; it does not change the voltage coming from the wall. Check the label on each charger and device to see whether it accepts a range of voltages. If it does, a universal adapter is enough for charging phones, tablets, and laptops. If it does not, you may need a voltage converter as well. When you are unsure, follow the manufacturer’s instructions for the adapter and the device.

For flexibility across multiple destinations, choose a universal adapter that accepts several plug types and includes USB ports. A universal adapter with built-in surge protection can also help guard sensitive electronics, though not every adapter includes that feature. Compare universal adapters by plug coverage, number of ports, and output rating before you buy.

Pack your charging gear in your carry-on rather than in checked luggage. Spare lithium batteries and power banks must be carried on, not placed in checked bags, according to FAA PackSafe guidance. Check the current FAA page and your airline because policies can change. A multi-port USB charger can also reduce the number of wall adapters you need for a phone, tablet, watch, and camera.

Travel documents

Your passport is the centerpiece of international travel, but it needs company. Carry a valid passport, any required visa or entry permit, return ticket, hotel confirmation, travel insurance policy, and proof of required vaccinations if applicable. Keep the originals in a secure pocket or organizer, and store photocopies or scanned versions in a separate bag or on your phone. Some travelers prefer to keep digital copies in an encrypted folder for extra security.

Check the destination’s official entry requirements for passport validity, blank pages, visa processing, and any reciprocity fees. Entry rules vary by country and change often. If you travel with prescription medication, keep it in its original packaging and carry the prescription or a doctor’s note, then confirm the current rules with the embassy and your airline.

Security screening

At airport security, general TSA guidance lists what you can bring in carry-on and checked luggage. Most travelers no longer need to remove shoes at standard checkpoints under current TSA guidance, but screening rules can change, so check the official page before your trip. The TSA’s What Can I Bring page is a reliable starting point for questions about liquids, electronics, and personal items.

Money and payment backups

Try to arrive with more than one way to pay. In most cases, that means a credit or debit card, some local currency, and a backup stash of cash in a separate pocket or hidden pouch. A prepaid travel card or a second card stored somewhere other than your wallet can also help if one payment method is lost, stolen, or declined.

Before you leave, consider adding a travel notice with your bank or card issuer if that option is available, since some financial institutions still flag international transactions. Cash is not accepted everywhere, but relying entirely on cards can be risky in destinations with less reliable card networks. Carry a few low-denomination local bills for small purchases, and keep larger emergency cash in a separate place from your daily wallet.

Check the destination’s official travel advisory for currency restrictions, such as limits on bringing local currency in or out. Some countries require you to declare larger amounts, so it is worth reading the official guidance before you arrive.

Connectivity and communication

Staying connected abroad usually starts with your phone. If your phone is unlocked, you have more options: use a local data eSIM, a travel data plan from your current carrier, or a prepaid SIM card. Each works differently for data, calling, and setup, so check what your phone and carrier support and whether the destination has good coverage.

Download offline maps, translation resources, and booking confirmations before you go. A portable charger or power bank keeps your phone usable through long layovers and days of navigation. Remember that spare lithium batteries and power banks belong in your carry-on, so pack them where you can reach them. If you bring multiple devices, a multi-port USB charger with a universal adapter can keep everything powered with minimal extra gear.

What you can skip

Not every travel accessory deserves space in your bag. Skip a single-country adapter if you are visiting multiple destinations; a universal adapter is more useful. Skip a separate voltage converter if all of your chargers are dual voltage and list the range you need. Skip bulky guidebooks when offline maps and official websites provide the same information. And skip duplicate packs of items you can easily buy at your destination, such as basic toiletries or a spare charger for every device.

Evaluate each item against your actual itinerary. A long-haul flight to one city requires different accessories than a multi-country rail trip. If you want a broader framework for the rest of your packing, the international travel gear page organizes options by trip type and travel style.

FAQ

Do I need a voltage converter?

It depends on your devices. If your chargers and electronics are labeled to accept the voltage range used at your destination, a universal adapter alone is enough. If they are not, you need a voltage converter as well. Check each label and follow the manufacturer’s instructions for safe use.

Can I pack a power bank in a checked bag?

No. According to general FAA PackSafe guidance, spare lithium batteries and power banks must be in carry-on bags, not checked bags. Airline policies can vary, so check the current FAA page and your airline before you fly.

How do I check official travel advisories?

Use the official government travel advisory page for your destination, plus the embassy or consulate website for entry and health requirements. Advisory levels change, so check the current official page before you finalize plans and again before you leave for the airport.

Use this checklist as a starting point, then tailor it to your destination and travel style. A little preparation goes a long way toward a smoother trip. For a closer look at individual items, browse the international travel accessories guide before you decide what makes the cut.
