🔋 Straight Talk, No Cap: Can I Bring a Portable Charger on Southwest Airlines? ✈️
Hey, what's up, travel junkies and digital nomads! You know the drill. You’re packing your bags, ready to jet set on the legendary Southwest Airlines, the carrier that lets you check two bags for free (say whaaat?!). You’ve got your sweet playlist ready, your oversized travel pillow, and then you look at that trusty portable charger—your lifeblood, the keeper of your phone’s soul—and a cold dread hits you. Can I actually bring this thing on the plane? Is this the moment the TSA agent is gonna look at you and say, "Nah, fam, that spicy brick gotta stay"?
Relax, chill out, buttercup. The short answer is a resounding heck yeah, you can bring your portable charger on Southwest. But, and this is a massive "but" with extra emphasis, there are some rules that are super important to follow, or you might find your prized power bank getting the ultimate cold shoulder at the security checkpoint or, worse, mid-flight drama! We're talking lithium-ion batteries here, and those little guys can get a little firey if they’re having a bad day. Safety first, people! Let's break down the whole shebang so you can travel like a boss.
Step 1: 🛑 Stop! Do NOT Put It in Checked Luggage
This is not a drill, people. This is the number one, most critical rule set by the Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA), and Southwest is totally on board with this one.

1.1 Why the Big Ban on Checked Bags?
Listen, power banks are basically spare lithium-ion batteries, and they have the potential for a little something called "thermal runaway." Sounds like a cool sci-fi movie, but it’s actually terrifying. It means the battery can overheat, catch fire, or even explode. If this happens way back in the cargo hold where nobody can see it, it's a huge problem. A plane is not a rave, and we don't need unexpected pyrotechnics! That's why they must be in the cabin with you, where a flight attendant can drop a fire suppression bag on it faster than you can say "Wanna get away?"
Pro Tip: If you accidentally leave your portable charger in your checked bag, it's a huge hassle, and they might just pull your entire bag for inspection. Don't be "that guy."
QuickTip: Copy useful snippets to a notes app.
Step 2: 🎒 Pack it Right in Your Carry-On
Okay, so your portable charger is rolling with you in the cabin. But you can't just toss it in like a loose sock. You gotta treat this electronic superstar like the VIP it is.
2.1 The Watt-Hour Wrangle (Don't Freak Out!)
This is where the math nerds flex. Portable chargers are limited by their Watt-hour (Wh) rating, not their size. Most common power banks are in the clear, but here's the lowdown, according to TSA/FAA guidelines that Southwest follows:
100 Wh or Less: Totally fine! This covers most consumer power banks (think 27,000 mAh or less, typically). You can bring a bunch of these—up to 20 spare batteries is the FAA limit, but who even owns that many?
101 Wh to 160 Wh: Hold your horses! You need airline approval for these beefier bad boys. You’re limited to only two of these spare batteries per person, and you need to get the OK from a Southwest agent. This is usually for the massive laptop chargers.
Over 160 Wh: Game over, dude. These are generally forbidden in passenger luggage, checked or carry-on. Leave the battery that can power a small village at home.
2.2 Protect Those Terminals, Homie
When you pack your charger in your carry-on, you need to make sure the metal connectors (the terminals) don't accidentally touch other metal things (like keys, coins, or other chargers) and cause a short circuit. Short circuits = bad news bears.
Tip: Context builds as you keep reading.
How to Protect Them: Throw them back in their original packaging (if you still have it, you're a legend), put them in a separate plastic bag or protective pouch, or simply slap some electrical tape over the exposed metal ends. Easy peasy.
Step 3: 🛋️ The Southwest In-Flight Visibility Vibe Check
This is the newest, spiciest rule from Southwest, and it’s a big deal. They are stricter than the general FAA/TSA rules when you're actually using the charger. You gotta be in compliance, or the flight crew might come at you sideways.
3.1 Keep it Out and Keep it Seen!
Southwest has gone the extra mile for safety. You can absolutely use your portable charger to juice up your phone or tablet while flying, but:
 |
No Charging in a Bag: Zero cap! You can't stick your phone and the charger inside your backpack or purse and let it charge secretly. If it starts overheating, nobody will know until it's too late.
Plain Sight is the Play: When it is in use, the power bank must be out of any baggage and remain in plain sight. Think on your tray table, or sitting next to you on the seat, or even in the seat pocket—as long as it’s visible.
Overhead Bins are a No-Go: Do NOT charge any device in the overhead bin. Period. End of story. This is a big "Duh!" moment, but people try it.
Step 4: 🚨 When in Doubt, Just Ask!
Seriously, if you are rocking a massive charger and can't figure out the Wh rating, or if you're feeling sketchy about your packing job, the best move is to be a good human and talk to the folks whose job it is to keep you safe.
QuickTip: Read again with fresh eyes.
TSA Agents: If you have questions about your charger before you're past security, pull it out and ask the agent at the checkpoint. They've seen it all, trust me.
Southwest Gate Agents/Flight Attendants: If you're on the plane and still confused about the use rule, a friendly flight attendant will set you straight. They are trained to handle these things and will appreciate you asking.
Bottom line: Your portable charger is your wingman for a long flight, keeping your Insta stories flowing. Treat it with respect, follow these steps like they're the gospel, and you'll be coasting through the skies with a fully charged phone and zero drama. Now go book that flight!
FAQ Questions and Answers
How do I calculate my portable charger's Watt-hours (Wh)?
Most portable chargers only show the capacity in milliamp-hours (mAh). To find the Wh, you'll use a simple formula: . Most lithium-ion power banks have a standard voltage of 3.7V. For example, a 20,000 mAh charger would be , which is totally fine!
How many portable chargers can I bring on Southwest Airlines?
You can bring a reasonable number of spare lithium-ion batteries (including power banks), up to 20 total per person is the FAA limit. However, the practical limit is determined by the Wh rating. You can bring many under 100 Wh, but only two per person in the 101-160 Wh range (with airline approval).
Tip: Summarize each section in your own words.
What is the maximum size (mAh) for a portable charger without approval?
Based on the 100 Wh limit and assuming the standard 3.7V, the maximum capacity without special airline approval is approximately 27,000 mAh. Anything above this should be checked against the Wh calculation and may require airline approval or be prohibited.
Can I charge my phone using the power bank while the plane is taxiing or during takeoff/landing?
Generally, yes, you can charge your phone using your power bank during the flight. However, you must adhere to Southwest's specific rule: the power bank must be out of your bag and in plain sight while charging. Standard restrictions for portable electronic devices (PEDs) during critical phases of flight (taxiing, takeoff, and landing) apply, meaning the device being charged should be held or secured, and potentially stowed if the flight crew requests it.
What should I do if my portable charger starts smoking or gets hot on the plane?
Do NOT touch it or attempt to extinguish it with water! Immediately notify a flight attendant. They are trained for this exact scenario and will use a specialized fire suppression bag (often called a fire containment bag or F.A.B.E.) or an appropriate fire extinguisher to safely cool and contain the battery until landing. Your job is to stay calm and follow their instructions.
