Faine
Ever been 30,000 feet in the air, your phone at 5%, no outlet in sight, and silently panicked? Yeah, we’ve all been there. Flying today means staying powered up—especially with long layovers, in-flight entertainment apps, and gate changes being announced on mobile apps. That’s why packing the right portable charger before you fly is a game-changer.
This isn’t just about tossing a random power bank into your bag. It’s about smart packing, smart charging, and avoiding the dreaded “low battery” notification mid-journey.
Let’s dive into 7 must-pack portable charger tips before you fly—all tailored to help you stay connected, charged, and chill.
Why You Should Never Travel Without a Portable Charger
Before we get to the tips, let’s be real—modern travel depends on your tech. From e-boarding passes to checking in online, portable power isn’t optional anymore. Whether you’re heading out for a weekend getaway or an international adventure, your gadgets need juice.
Portable chargers are the ultimate travel essentials. And guess what? The right one can save your trip from going sideways.
Tip 1: Choose a High-Capacity Charger That Suits Your Flight Duration
What Is a High-Capacity Charger?
When we talk about high-capacity, we’re talking 20,000mAh or more. That’s enough to charge most phones 4–6 times, a tablet 2–3 times, and even give your laptop a boost.
Check out our high-capacity chargers if you’re not sure where to start.
Long-Haul Flights Need Long-Lasting Power
If your flight is more than 5 hours—or includes a layover—you’ll want something serious. Trust me, your battery will thank you when you’re stranded at Gate 23 with nothing but a half-charged iPad and no outlet.
Tip 2: Look for TSA-Approved and Flight-Friendly Designs
Avoid Chargers with Lithium Restrictions
Airlines and the TSA have rules around lithium batteries. Most portable chargers are fine, but make sure it’s under 100Wh (watt-hours) to be flight-approved. You’ll find the specs labeled on the device.
Want a checklist? We’ve got one: travel power checklist.
What Airlines Allow (and Don’t Allow)
Each airline may have specific rules. Some don’t allow chargers in checked baggage, while others want you to limit how many you carry.
So always check their battery policy before you go. Pro tip? Stick to carry-on.
Tip 3: Prioritize Fast Charging Support for Your Devices
Know the Output Requirements of Your Gear
Do you know how many amps your phone or tablet needs? Or whether your charger has Power Delivery (PD) for fast charging? If not, look it up. It could make the difference between a 30-minute top-up and a 2-hour struggle.
USB-C and PD Are Your In-Flight Friends
Today’s top portable chargers use USB-C, which is faster and more efficient. Especially if you’re charging a laptop or tablet.

Tip 4: Bring Multiple Charging Cables and Adapters
Different Devices, Different Needs
Your phone might use USB-C. Your friend’s might still use Lightning. Your camera? Who knows. Don’t assume one cable fits all.
Avoid the Mid-Air “No Cable” Panic
Ever packed your charger and forgot the cable? Yeah. Awkward.
A simple fix: stash extra cables in a zip pouch and toss it in your carry-on.

Tip 5: Waterproof and Rugged for Unpredictable Travel Mishaps
Don’t Let Spills or Drops Kill Your Charger
Travel can be chaotic. Drinks spill. Bags get crushed. Your power bank might get dropped running to a gate.
Opt for something waterproof and shockproof—especially if you’re the adventurous type.
Browse our outdoor charger picks for rugged options built to survive it all.
Tip 6: Charge Before You Leave and Learn Airline Power Policies
Don’t Rely on Plane USB Ports
Those USB ports on planes? They’re usually slow, unreliable, or don’t work at all. Don’t bank on them to get you through a 12-hour flight.
Fully Charge at Home, Not at the Gate
Make it a pre-travel ritual: phone charged, power bank topped off. Don’t wait until you’re at the airport, where outlets are either all taken or nowhere near your gate.

Tip 7: Don’t Forget to Pack It Accessibly in Your Carry-On
Avoid Packing It in Checked Luggage
Most airlines ban power banks in checked bags. Even if they didn’t, you wouldn’t want your power source in a place you can’t access mid-flight.
Keep It Handy for Unexpected Delays
Flight delay? Battery life dragging? You’ll be glad you kept it in your backpack or purse.
Packing help? Here’s a solid checklist to avoid last-minute chaos.
Pro Tips for Maintaining Your Portable Charger
Store Properly, Use Regularly
Like any battery, power banks need love. Store them at room temperature, use them every few weeks, and keep them out of the sun or extreme cold.
Avoid Overcharging and Extreme Temperatures
Leaving your charger plugged in forever? Bad idea. Extreme temps kill battery life, so keep it cool (literally and figuratively).
