What You Need to Know About Battery and Charger Rules for Airlines in 2026
If you travel with a portable charger, you’ll want to pay attention to some important rule changes happening right now. Airlines are tightening their policies on lithium-ion batteries and portable power banks, and the biggest headline of the year is American Airlines’ new limit: starting May 1, 2026, passengers may only bring two portable chargers on board, each rated at 100 watt-hours (Wh) or less.
Delta has followed suit with an identical policy, also effective May 1. These changes signal a clear shift in how airlines handle portable power, so whether you’re a frequent flyer or an occasional traveler, here’s everything you need to know before your next trip.
Why Are Airlines Cracking Down?
The push for stricter battery rules stems from a growing number of lithium-ion battery incidents on commercial flights. Lithium-ion batteries, while generally safe, can overheat and catch fire if they’re damaged, defective, or improperly stored. When that happens in the confined cabin of an airplane, the consequences can be serious.
American Airlines stated that the new policy is designed to allow crew members to respond quickly in case of any issues. By limiting the number of chargers and requiring them to stay visible and within reach—not tucked away in an overhead bin—flight attendants can better monitor and manage any potential risks.
The New Rules at a Glance
Here’s a summary of the current landscape for flying with portable chargers and spare batteries in the U.S.:
FAA / TSA Baseline Rules: Portable chargers and spare lithium-ion batteries must always go in your carry-on bag—never in checked luggage. Batteries rated at 100 Wh or less are allowed without airline approval. Batteries between 101–160 Wh require airline approval, and anything over 160 Wh is prohibited entirely. If you’re asked to gate-check your carry-on, you must remove all power banks and batteries and bring them into the cabin with you.
American Airlines (effective May 1, 2026): Maximum of two portable chargers per passenger, each 100 Wh or under. Chargers may not be stored in overhead bins, cannot be recharged during the flight, and must remain visible and within reach at all times.
Delta Air Lines (effective May 1, 2026): Matching American’s policy with a two-charger, 100 Wh limit.
Southwest Airlines (effective May 1, 2026): Maximum of one portable charger per passenger, under 100 Wh, and they must be kept with passengers, and may not be stored in overhead bins.
Other Major Carriers: While the TSA itself doesn’t currently cap the number of sub-100 Wh power banks you can carry, individual airlines can and do set their own limits. Expect more carriers to follow American and Delta’s lead throughout 2026.
What Does This Mean for Travelers?
The days of tossing three or four random power banks into your bag are coming to an end—at least on most major airlines. With a two-charger limit, every portable charger you pack needs to earn its spot. That means choosing chargers that are compact, powerful, and versatile enough to keep all your devices going throughout a long travel day.
It also means understanding your charger’s watt-hour rating. Most portable chargers under 27,000 mAh fall well within the 100 Wh limit, but it’s always a good idea to check the label. If the rating isn’t listed in watt-hours, you can calculate it: multiply the milliamp-hour (mAh) rating by the voltage, then divide by 1,000.
Travel-Ready Chargers That Make the Cut
When you can only bring two chargers, you need them to pull double duty. Here are a few Nimble products built for exactly this kind of travel:
CHAMP Portable Charger (10,000 mAh)
The CHAMP 10K is a standout pick for air travel. Smaller than a deck of cards, it packs 10,000 mAh of power and can charge two devices at once with up to 20W of Power Delivery. That means you can top off your phone and your earbuds at the same time without carrying a second charger. It supports USB-C PD 4.0 and QC 4.0, so it fast-charges both iPhones and Android devices. At 37 Wh, it’s well under the 100 Wh airline limit. Plus, the built-in lanyard loop makes it easy to clip to a bag and keep accessible—exactly what the new American Airlines rules require.
CHAMP Pro (20,000 mAh, 65W)
For travelers who need to charge laptops on the go, the CHAMP Pro delivers 65W of power and 20,000 mAh of capacity—enough to recharge a MacBook Air, an iPad, or multiple phones. It charges two devices simultaneously and still comes in under the 100 Wh limit. If you want maximum power in your two-charger allowance, this is the one to pack.
WALLY Pro Portable Wall Charger
The WALLY Pro is a clever hybrid: it’s a wall charger and a portable battery in one. Plug it into an outlet at the airport to charge your devices and the built-in battery simultaneously, then unplug and take the power with you onto the plane. It’s an especially smart choice when your charger count is limited because it does double duty.
PowerKnit Travel Kit
Don’t forget the cables. The PowerKnit Travel Kit bundles three durable, fabric-knit USB-C cables with the connectors you need for fast charging up to 60W. Toss the kit in your bag alongside your CHAMP and you’re set for any device.
Quick Tips Before You Fly
Check your charger’s label. Make sure the watt-hour rating is clearly printed on the device. If it’s worn off, consider replacing the charger—TSA agents may confiscate batteries without a visible rating.
Always carry on, never check. This has been the rule for years, but it’s worth repeating. Spare batteries and power banks are prohibited in checked baggage.
Keep chargers accessible. Under the new American Airlines policy, portable chargers must stay visible and within reach—not in the overhead bin. A seat-back pocket or personal item is ideal.
Choose quality over quantity. With a two-charger limit, invest in well-made, certified chargers that won’t overheat. All Nimble chargers are rigorously tested and certified against the highest safety standards.
Travel Smarter, Not Heavier
The new airline battery rules don’t have to slow you down. They’re actually a good reason to streamline your travel kit with chargers that are compact, powerful, and designed to keep multiple devices going. A single CHAMP 10K can replace two single-port chargers, and pairing it with a CHAMP Pro gives you enough juice for a phone, tablet, laptop, and headphones—all within your two-charger allowance.
