Yes — phone chargers and cables can go in hand luggage; power banks and other spare lithium batteries must stay in the cabin, never in checked bags.
Short answer first, then the nuance. A wall charger, plug, travel adapter, and cables are fine in your carry-on. The part that trips people up is any battery that is not installed in a device. That includes power banks and battery cases. Those items ride in the cabin only, with size limits. Get this right and security takes minutes, not an hour.
Taking Phone Chargers In Hand Luggage: What’s Allowed
The phrase “phone charger” includes a few parts. There’s the plug that goes in the wall, the cable, a power bank, and sometimes a battery case or wireless pad. Each sits under a slightly different rule in aviation. Here’s a quick side-by-side so you can pack with confidence before you head to the airport.
| Item | Hand Luggage | Checked Bag |
|---|---|---|
| Wall charger / USB plug | Allowed | Allowed |
| Charging cable or wireless pad without battery | Allowed | Allowed |
| Power bank <= 100 Wh | Allowed in cabin only | Not allowed |
| Power bank 100–160 Wh | Carry-on only, airline approval needed in many regions | Not allowed |
| Spare lithium battery (any size) | Carry-on only, terminals protected | Not allowed |
| Battery case for phones | Carry-on only | Not allowed |
Why this split? Lithium cells behave differently under pressure and heat. If a cell vents or overheats, cabin crew can spot smoke fast and step in. That’s why agencies like the TSA and the FAA PackSafe direct travelers to keep spares and power banks in hand luggage.
Are Phone Chargers Allowed In Carry-On Bags?
Yes. Put the wall plug and cable anywhere in your bag. Leave a power bank in your personal item or a side pocket you can reach from your seat. Gate agents may tag large carry-ons to go in the hold on busy flights. If that happens, pull your power bank and any spare cells out before the bag goes down the jet bridge.
How Battery Limits Work, Without The Jargon
Power banks and spare cells use watt-hours (Wh) to describe size. You’ll see a label like “10,000 mAh 3.7 V.” To convert, multiply volts by amp-hours. So 10,000 mAh at 3.7 V lands near 37 Wh. Brands print this on the case; if a pack doesn’t show it, skip it for air travel. The common ceiling is 100 Wh without airline sign-off. Some carriers allow up to 160 Wh with prior approval. Devices with a battery installed, like a phone or tablet, can go in either bag, but most flyers keep them with the cabin crowd so they can charge and keep an eye on heat.
Spot The Label Fast
Flip the pack and scan for “Wh.” Can’t find it? Look for the two numbers and do the quick math on your phone. Many airlines keep a two-pack limit for large spares between 100 and 160 Wh. Smaller packs under 100 Wh rarely draw a second glance at screening, provided the label is clear and the terminals can’t short.
Smart Packing Steps That Save You Time
Security lines move faster when your charger kit lives in a pouch. Place wall plugs, cables, adapters, and a slim power bank together. Keep the pouch near the top of your backpack. If an officer wants a closer look, you hand over one neat bundle and you’re on your way.
Shield The Terminals
Loose batteries can touch metal and spark. That’s why rules ask you to shield exposed ends. Use the original sleeve, a small case, or tape over contacts. Power banks rarely have bare terminals, but some DIY cells and drone packs do. Treat them the same way: shield, bag, and separate from metal bits or coins.
Mind Airline-Specific Quirks
Carriers can add their own limits on top of national rules. A few airlines cap the number of power banks per person. Some ask you not to charge from a power bank while it sits in an overhead bin. A quick check of your booking email or the carrier “dangerous goods” page avoids last-minute drama at the gate.
Regional Notes You Should Know
Rules line up across regions, with small wording changes. In the United States, TSA screens and FAA sets safety rules. Power banks ride in hand luggage only, with size limits stated in Wh. In the UK, the Civil Aviation Authority safety advice states the same approach and spells out packing steps. Across the EU, EASA pages remind travelers to keep spares in the cabin and to shield terminals. You can skim EASA summaries if you want extra certainty before a long trip.
Links You Can Trust
If you want the rule in writing, point your browser to the TSA’s page on power banks, the FAA PackSafe battery page, and the UK CAA safety list above. Together they spell out the carry-on-only rule for spares, the 100 Wh baseline, and the tighter handling of large packs between 100 and 160 Wh.
Carry-On Charger Kit: A Simple Build
Make a small kit you can move from bag to bag. Start with one wall plug that has two ports, a short USB-C cable, a short Lightning or micro-USB cable, a flat three-prong adapter for hotel rooms, and a power bank under 100 Wh. Add a zip bag with spare tips and a slim roll of tape for battery contacts. Label the bag “chargers” so family can find it. This small routine cuts rummaging at checkpoints and helps in hotel rooms with tight outlet space.
What To Do When There’s No Label
Some packs don’t print Wh or even volts. You have two paths. First, look up the model on the maker’s site to find a Wh line. If you can’t confirm the Wh, leave that pack out of your trip and use one that shows the rating. Security staff may ask to see markings; a clean label avoids a long chat and a bin full of gear you can’t carry through.
Are Chargers Fine During International Transfers?
Yes. The same rules apply when you land for a connection and pass through screening again. Keep the power bank in your day bag, not in a checked roller. If a transit desk takes your carry-on due to size, pull the battery and spare cells before the hand-off. On routes with extra screening, staff may swab the power bank or ask you to power a device. A labeled pack speeds that step. If an agent asks about capacity, state the Wh number on the case and show the label.
What To Do At The Checkpoint
Walk up with your charger pouch at the top of the bag. Tablets usually come out; phones and power banks usually stay in. Follow the officer’s cue. If asked to remove items, place the pouch in a bin by itself so the scanner gets a clean view. Skip the jacket pocket routine. Bags swallow small gadgets, and you end up re-scanning.
If Your Carry-On Gets Gate-Checked
It happens on full flights. Pull your power bank, spare cells, vapes, and matches before the tag goes on. Slip them into your personal item. Agents know this drill and will give you a minute.
Device-Specific Tips That Keep You Compliant
Phones and tablets: Allowed in both bags. Turn them off if you pack them in the hold to avoid accidental activation. Battery cases: Treated as a spare. Keep them with you. Laptops: Built-in battery stays installed. If you remove a laptop battery, treat it like any spare cell and carry it on. Wireless chargers: If the pad holds a battery, it’s a power bank. If not, it’s just a cable on a disc, so it can ride anywhere.
Traveling With Kids Or A Group
Shared gear gets messy fast. Give each person a color-coded cable and a name tag on their pack. Keep the family power bank in the seat pocket while charging so you can spot heat or a loose cable. If a teen carries their own pack, check that the label shows Wh and that it sits under 100 Wh.
Picking A Travel-Friendly Power Bank
Choose a pack that shows Wh clearly, uses a metal shell or sturdy plastic, and has short-circuit protection. A 10,000–20,000 mAh unit powers a long day for most phones. Larger bricks that can run a laptop sit near the 100 Wh line, so check labels before you buy.
| Battery Or Device | Typical Wh | Air Travel Rule |
|---|---|---|
| Phone power bank 10,000 mAh | ~37 Wh | Carry-on only |
| Phone power bank 20,000 mAh | ~74 Wh | Carry-on only |
| High-capacity bank 30,000 mAh | ~111 Wh | Carry-on only, may need airline approval |
| Laptop power bank 50,000 mAh | ~185 Wh | Not permitted |
| Phone battery case | 10–15 Wh | Carry-on only |
Why Power Banks Get Special Handling
Lithium cells pack a lot of energy in a small box. A bent cell, a cheap charger, or trapped heat can push a pack into a runaway state. Smoke and heat in a cabin get spotted fast, and crew carry gear to cool and contain the unit. A suitcase in the hold is out of reach. That gap drives the cabin-only rule for spares across agencies.
Preventing Mid-Flight Headaches
Keep the pack in sight. A seat pocket is perfect. Don’t leave a charging phone inside a closed bag or a coat in the overhead. If a device gets hot, unplug it and flag a flight attendant. Cabin crews carry fire-safe bags and follow a clear drill, and they act faster when they can see the source.
Simple Safety Habits
- Use cables in good shape. No frayed ends.
- Avoid loose coins around exposed battery contacts.
- Skip cheap packs with no label or brand.
- Power down devices you won’t use.
- Keep a small piece of tape for spare cell contacts.
Hand Luggage Layout That Works
Put laptops and tablets against the back panel of your backpack. Place the charger pouch on top of clothing so it comes out in one move. Use a slim case for adapters so prongs don’t snag mesh pockets. If you carry a universal adapter, leave sharp travel plugs in a hard shell.
When You Need Extra Capacity
Some trips run long. Two small packs can be better than one giant brick. Two labeled 20,000 mAh units ride in the cabin with no fuss at most airlines. A single 30,000 mAh pack may cross the 100 Wh line, which introduces an approval step you might not want to chase during a layover.
Common Myths That Slow People Down
“Chargers can’t go in carry-on.” The plug and cable can go anywhere. The rule applies to spare batteries. “I can tape a big pack and check it.” Tape helps with short-circuit protection, yet checked placement stays off the table. “Only the U.S. bans batteries in the hold.” Agencies in the UK and EU publish the same stance, and airlines around the world align with it.
Quick Math For Any Pack
Here’s the rule of thumb many travelers use. Wh = (mAh ÷ 1000) × V. Common pack voltage is 3.6–3.85 V. That puts 10,000 mAh around 36–38 Wh, 20,000 mAh around 72–77 Wh, and 30,000 mAh a touch over 100 Wh. If a vendor only lists mAh with no volts, assume 3.7 V and run the number. If it lands above 160 Wh, leave it at home.
Small Airports Versus Big Hubs
Screening style varies by airport. At small fields, agents may ask to see the power bank label. Big hubs move fast and rely on the X-ray. Both work. Keep the pack handy with the label facing out. A clear case helps, and a tidy pouch speeds the line. Turn the pack off before boarding if possible too.
Final Packing Checklist
Wall charger and cable anywhere. Power bank in hand luggage only. Spare cells shielded. Labels visible. Charger pouch near the top of your bag. If a gate agent checks your roller, pull the batteries first. Simple steps, smooth trip. Travel ready.
