Planning a big adventure? As a seasoned globe trotter, I’ve learned the key is to pack efficiently, and that means bringing things that truly make a difference.

I’m not referring to that hoodie you think you need for questionable weather conditions or spare socks in case yours get wet.

I mean the following life savers that’ll spare you a lot of hassle while traveling. Make sure you don’t leave home without any of these essentials…

1. Global Twist Outlet Adapter ($16): If you’re spending a week here and two weeks there and maybe a month here and just a few hours there, you’ll quickly realize how frustrating outlets can be. Why? They’re different all across the globe. Rather than carrying a million chargers with easily misplaced connectors, this single adapter works in more than 150 different countries.

2. Hydro Flask Water Bottle ($30 for 18 oz.): With Hydro Flask, you can keep hydrated anywhere you go… even if you’re going to be on the road for a lot of hours. It’s made of durable 18/8 pro-grade stainless steel so it’ll keep your liquids cold for up to 24 hours and hot for up to six. Plus it’s BPA-Free and Phthalate-Free.

3. Skyroam Portable Wi-Fi ($150): Never worry about overage or international roaming charges or changing SIM cards again. Skyroam gives you unlimited global 4G Wi-Fi, and you only ever pay a flat rate of $8 for 24 hours instead of buying plans that accrue fees. You’ll save up to 95 percent on international data roaming, and you can connect up to five devices to it, too. It also doubles as a portable power bank.

4. Victorinox Swiss Army EvoWood 17 ($64): A Swiss Army Knife of any kind is a good thing to keep on you while traveling. This one happens to be part of the part of the Victorinox Delemont Collection and features genuine hardwood handles and a 2.5-inch blade, as well as eight other implements that perform a total of 13 functions. You’re bound to find a purpose or two for it at some point along your journey.

5. Tile Mate ($20): Hook a small Bluetooth tile onto your luggage and travel with peace of mind. It uses a corresponding app that offers a map that’ll track your luggage in case it gets lost or stolen. If you lose your phone instead, you can actually use it in reverse; just press the Tile twice to make your phone ring even if it’s on silent, or put a lock screen on it. If you’ve lost everything, log into the Tile Mate website to use the map or make your phone ring from there.

6. LifeStraw Water Filter ($20): If you’re going on some kind of outdoor adventure, you should definitely have a water filtration system with you. The LifeStraw will turn up to 1,000 liters (or 264 gallons) of contaminated water into safe drinking water for you by removing 99.9999 percent of waterborne bacteria like E-Coli and 99.9 percent of waterborne protozoan parasites like Giardia and Cryptosporidium.

7. Master Lock Bluetooth Padlock ($70): Don’t leave home without your own padlock, because you should never trust padlocks that have been provided—thieves may already know how to crack ’em open. This durable, metal padlock is Bluetooth-enabled, which means that you can open it from your phone and share access to it via the free Master Lock Vault eLocks app. The app also allows you to monitor access history and will send you tamper alerts in the event of suspicious activity.

8. mophie Powerstation XL ($130): Probably one of the most important things you can have with you while traveling is power. You’ll need your phone or other devices in the event of an emergency, and the mophie powerstation XL is the longest lasting universal battery on the market. On top of a 12,000mAh battery, the XL is fully capable of charging two tablets simultaneously and will charge your smartphone up to eight times before ever needing a charge itself.
