Your smartphone is a travel essential. You need it to schedule flights, book hotels, contact friends, find local restaurants, take pictures, translate languages and get directions to tourist sites you’ve never been to before. You have no choice — you have to take it with you.

These are some additional travel essentials that you should bring along with your smartphone:

Emergency Fund

There are plenty of emergency expenses that could throw massive wrenches into your travel budget. Maybe you have an allergic reaction, and you need to pay for immediate treatment at a medical clinic, or maybe your phone breaks, and you need to fix it fast. That’s why an emergency fund is a travel essential.

What if you don’t have enough in your emergency fund? If you don’t have enough savings, then you could try applying for a loan by phone or online and see whether you get approved for it. If you’re approved for the loan, you can use the borrowed funds to cover your emergency expense in a short amount of time and then focus on a repayment plan later. It’s a convenient backup plan that you can turn to when your emergency fund doesn’t work out.

Power Bank

You don’t want to get a low battery at the wrong moment during your trip. You need your smartphone to have full power so that you can use the maps to find your destination, use the translator apps to read signs and use the camera to take pictures of moments that you want to be cemented in your memories. To make sure that you have a full battery for as long as possible, you should bring a top-quality power bank on your trip.

Travel Plug Adapter

You don’t need to worry about using up your power bank when you’re back at your hotel or your Airbnb. You can just use your charger to bring your smartphone battery up to full — that is, if your charger fits into the outlet. There are different plug shapes around the world, so if you’re traveling to an international destination, you’ll want to check what type of plug shape they have and buy an adapter to match it.

Waterproof Case

You’re planning a vacation where you’ll be spending 90% of your time at the beach, soaking up the sunshine and swimming in the glittering waters. For this type of trip, you’ll need to bring a waterproof smartphone case. The simple accessory will keep your smartphone safe and dry. It will also allow you to bring your smartphone into the water with you so that you can take incredible photos without having to worry about water damage.

Don’t dismiss this accessory just because you have a water-resistant smartphone model. Water-resistant doesn’t mean waterproof. It means that your phone can handle small encounters with water, like dropping it into a puddle or spilling a drink over it. It doesn’t mean that you should dunk it underwater at any chance you get. This will inevitably cause problems.

The type of water that you put your phone under can also do damage. Pool water contains chemicals like chlorine, and seawater contains lots of salt and sand, which don’t mix well with your delicate tech. So, get an accessory that will keep your smartphone secure whenever you plan a beach vacation.

Get these essentials before you pack your bags for your flight. You’ll be thankful that you brought them on vacation with you.
