Whenever and wherever you travel, your digital devices are along from the ride. Nowadays, your phone is your boarding pass, your map, your hotel key, and your lifeline — which means a dead battery or spotty signal can be a major headache.
Here's how to keep your power, connectivity, and digital documents working for during your next adventure.
🔋 Smart Charging on the Road
Let's start with the obvious: Keep your devices charged. But how you charge them while traveling matters more than you might think.
Public USB charging stations (like the ones in airports, hotels, train stations, and shopping centers) are convenient, but they may carry certain risks. Recently, juice jacking has made headlines. This is a potential cyberattack where criminals tamper with public USB ports to steal data or install malicious software on connected devices while they charge.
It's worth noting that while juice jacking has been demonstrated to be technically possible, we don’t know how frequently it occurs. Still, the stakes may be worth taking simple precautions, especially if you're traveling with a work device or accessing University accounts.
- Pack your own wall charger and cable. A standard power outlet only supplies electricity — it can't transfer data — making it the safest way to charge away from home.
- Bring a portable battery pack. This is the single best investment for any traveler. A charged power bank means you're never dependent on whatever ports happen to be available. Charge it up the night before you leave.
- Keep your screen locked while charging. Most devices won't allow data transfer when the screen is locked, which adds a simple extra layer of protection.
🗺️ Download Your Maps Before You Go
Here's a scenario that happens to travelers all the time: You arrive somewhere new, open your map app, and find yourself in a dead zone with no signal and no directions. Don't let that be you.
Both Google Maps and Apple Maps let you download offline maps before your trip so you can navigate without any data connection at all. Offline maps work without signal and can save battery, data, and stress. This is especially useful if you're road tripping through areas with spotty coverage or traveling internationally where roaming charges add up fast.
- Google Maps: Tap your profile picture, select Offline Maps, then Select Your Own Map. Drag and zoom to cover your destination area and tap Download. Turning on Auto-Update ensures your maps stay current.
- Apple Maps (iOS 17 and later): Tap your profile icon, select Offline Maps, then Download New Map. Search your destination, adjust the coverage area, and tap Download. Once downloaded, you can navigate with turn-by-turn directions and search for locations even without Wi-Fi or cellular service.
Pro tip! Download maps while you're still on Wi-Fi at home to avoid eating into your data. And if you're covering a long road trip route, make sure your downloaded areas overlap so you don't hit any gaps mid-drive.
📱 Protect Your Digital Travel Documents
More travelers than ever are going fully digital. Boarding passes, hotel confirmations, rental car QR codes, and ID verification can all be stored on your phone. It's convenient, but it also means that a dead battery or a locked-out phone at the wrong moment can cause real problems. Here's how to make sure that doesn't happen to you:
- Save your boarding pass to your phone's wallet app. Apple Wallet and Google Wallet store boarding passes offline, so you can access them even without a data connection or signal. This is much more reliable than keeping a tab open in your browser.
- Screenshot your confirmation emails as a backup. A saved screenshot of your boarding pass, hotel confirmation, or rental car QR code doesn't require an internet connection or an app to display. Store them somewhere easy to find like a dedicated album in your photo app.
- Keep your phone secured with a PIN or password. Biometrics are convenient but can be compelled in certain circumstances. A lock screen is your first line of defense against someone accessing your travel documents and personal accounts.
- Charge up before you leave for the airport. It sounds obvious, but it's worth saying — don't head out the door at 30%. Top off your phone and remember to pack a charger.
