Avoid surprises: know which chargers and power stations can fly. Practical 2026 rules, model notes (Jackery, EcoFlow) and step-by-step packing advice.

Quick Guide: Airport-Approved Chargers, Power Stations and What You Can Bring Onboard

Hook: You found a wildly cheap fare—but at the gate you’re stopped because of the giant Jackery or EcoFlow in your bag. Airport battery rules are one of the fastest ways to get hit with surprise fees, denied boarding or last-minute shipping charges. This guide gives the exact, practical rules and packing steps you need in 2026 so your trip stays on schedule and your devices stay powered.

The bottom line — most important rules first

Spare lithium batteries and power banks must travel in carry-on only. They’re generally prohibited in checked baggage.
100 Wh is the safe everyday limit. Most airlines allow batteries and power banks up to 100 watt-hours (Wh) in carry-on without prior approval.
100–160 Wh needs airline approval and is limited in quantity. Many carriers allow 2 spare batteries in this range with written approval.
Over 160 Wh (portable power stations like big Jackery/EcoFlow units) are not permitted on passenger aircraft. These must be shipped by cargo under dangerous-goods rules or left home.

Why this matters for deal hunters and budget travelers

Value shoppers prioritize cheap flights and fast turnarounds. But a denied boarding or forced baggage re-check because of an oversized battery can wipe out any fare savings. Treat battery rules like carry-on size limits: plan them into your itinerary, and you’ll avoid fees, delays and stress.

2026 trends you need to know

Regulators and airlines continued tightening enforcement through 2024–2025, and in 2026 the travel industry is operating with stricter, more consistent checks at airports worldwide. Two practical outcomes:

Manufacturers now commonly print Wh ratings on power banks (not just mAh), making compliance easier at security checkpoints — see our roundup on best budget powerbanks and travel chargers for examples of labeling practices.
Airports and lounges increasingly offer power-bank rental kiosks and monitored charging lockers, letting you avoid carrying large spare batteries altogether for short trips — consider portable power & lighting kits and rental options if you regularly travel with gear.

Key rules summarized (IATA / FAA / TSA practical interpretation)

Regulatory frameworks (IATA Dangerous Goods Regulations, FAA guidance and national aviation authorities) inform airline policies. Below is the practical, traveler-facing summary you can use at check-in and security.

1) Spare lithium-ion batteries & power banks

Carry-on only: Spare batteries (including power banks) must be carried in the cabin; they cannot be in checked luggage.
Up to 100 Wh: Allowed in carry-on without airline approval. This covers most consumer power banks (for example, a 20,000 mAh power bank at 3.7V ≈ 74 Wh).
100–160 Wh: Often allowed but only with airline approval and usually limited to two spare units. Always request written approval before arrival.
>>160 Wh: Prohibited in passenger aircraft (both carry-on and checked). These units must be transported via cargo under specialized dangerous-goods procedures.

2) Installed batteries inside devices

Devices with installed batteries (laptops, cameras, e-bikes with removable packs installed) are usually allowed in checked or carry-on baggage, but airlines prefer them in carry-on for inspection and fire safety.
For laptops and phones, remove or switch off the device if instructed by security. For e-bikes, airlines and security often require that the battery pack be removed and carried in cabin when possible.

3) Portable power stations (Jackery, EcoFlow, large units)

Most consumer portable power stations (the Jackery HomePower 3600 Plus at around 3,600 Wh is a clear example) exceed 160 Wh and are not allowed on passenger flights. Even smaller “DELTA”-class EcoFlow stations often exceed the 160 Wh threshold depending on the model. Practical options:

If the unit is >160 Wh: Do not try to check or carry it. Book cargo shipping with a hazmat-approved carrier; expect extra cost and lead time.
If the unit is ≤160 Wh: You may be able to carry it in cabin with airline approval — but check exact specs and carry documentation.
For travel to remote locations: consider renting a station at your destination, using airport rental lockers, or switching to smaller, airline-friendly power banks — and consult field reviews like our solar-powered cold boxes & battery strategies if you need off-grid power options.

“If it can be removed from the device, treat it as a spare battery: it belongs in your carry-on.”

How to read battery specs — convert mAh to Wh

Many travelers see mAh and aren’t sure what it means for air travel. Use this conversion:

Wh = (mAh ÷ 1000) × V

Most power banks list capacity as mAh at a nominal cell voltage of 3.7V. So a 20,000 mAh power bank: (20,000 ÷ 1000) × 3.7 = 74 Wh.
If a power bank lists Wh directly, use that number — it’s the clearest indicator for airline staff.

Practical packing checklist — what to do before you fly

Check the Wh rating on every spare battery and power bank. If only mAh is shown, convert to Wh using 3.7V or ask the manufacturer.
Keep all spare batteries/power banks in your carry-on. Do not pack spares in checked luggage.
Protect terminals. Use original packaging, terminal covers or tape to prevent short-circuits. Put each item in a plastic bag if possible.
If between 100–160 Wh, request airline approval in writing before travel. Contact the airline’s hazardous materials or customer service desk and get the approval email or PDF to show at check-in.
If a unit is >160 Wh, DO NOT bring it on the plane. Arrange cargo shipment or rent at destination.
Bring documentation. Save receipts/spec sheets or photos of the manufacturer’s label showing Wh; present them at check-in if asked.
Minimize counts. Airlines that permit 100–160 Wh typically restrict the number (often two spares). Don’t bring five 120 Wh banks thinking you’ll be fine.

Model-specific practical notes — examples for 2026

Use these examples to quickly categorize common equipment. Always check the label on the specific unit you’re traveling with.

Jackery HomePower 3600 Plus

Real-world rule: At ~3,600 Wh (manufacturer specs), this unit far exceeds the 160 Wh passenger limit. It cannot travel on passenger aircraft. Ship via cargo/ground freight or use a destination rental — read our field notes on solar & battery field strategies for long‑term remote setups.

EcoFlow DELTA / DELTA 3 Max series

EcoFlow’s DELTA-class home units range widely. Smaller “River” or compact DELTA variants may be under 160 Wh, but the larger DELTA and HomePower equivalents are usually above the limit. Always check the specific model’s Wh before planning to carry it on.

Typical power banks (Anker, RAVPower, phone-branded)

Most consumer power banks fall under 100 Wh (e.g., 10,000–27,000 mAh at 3.7V). These are carry-on friendly. High-capacity models marketed for camping may approach or exceed 100 Wh — check the label. For hands-on comparisons and travel-friendly picks, see our best budget powerbanks review.

Dealing with airline staff and security — scripts and proof

Airport staff can be inconsistent. Use this short script and documentation strategy to speed checks:

Show the Wh label on the unit. If only mAh is shown, show your phone’s calculator conversion.
If it’s 100–160 Wh: present the airline approval email or ticket annotation.
If denied: ask specifically for the hazardous-materials desk or customer-service line rather than arguing with front-line employees.

Shipping large batteries/power stations — your options

When a unit is >160 Wh, passenger travel is not an option. Here’s how to ship it safely without surprise costs:

Contact the manufacturer: Many manufacturers (Jackery, EcoFlow) provide approved shipping guidance and packaging tips.
Use a hazmat-approved cargo carrier: FedEx, UPS and specialized freight forwarders handle large lithium batteries but with strict documentation, packaging, and cost. Expect extra fees and longer transit times — consult providers that specialize in dangerous goods and consider their documentation processes described in logistics and compliance briefings like cargo & compliance overviews.
Hire a professional: Dangerous-goods specialists package, label and file necessary paperwork for air or sea cargo transport.
Consider ground freight: For domestic moves, ground hazardous materials shipping can be cheaper than air cargo options.

Airport and airline quirks — what to watch for

Some international carriers and airports apply stricter local rules. Australia, New Zealand and certain Asian carriers can be less flexible — always check domestic rules for the country you depart from.
Low-cost carriers may have strict carry-on enforcement. Even if your battery meets Wh limits, aggressive gate checks or small overhead bins can create problems.
Security screening times may increase. Expect extra inspection time for multiple power banks or large installed batteries; budget a longer connection time.

Tip: Add extra time at the airport

During busy periods in 2026, stricter enforcement means extra queue time at security. If you’re traveling with several batteries or a borderline unit, add at least 30 minutes to your pre-departure schedule — it's a small time cost compared with last-minute shipping fees and missed flights; our bargain-hunter toolkit walks through time-and-cost tradeoffs.

Packing scenarios — quick decisions for common travelers

Scenario A: Weekend trip, several devices, one 20,000 mAh power bank

Outcome: Good to go. 20,000 mAh ≈ 74 Wh — carry in cabin, protect terminals, keep accessible. For compact travel picks, see our powerbank field review.

Scenario B: Camping trip with Jackery HomePower 3600

Outcome: Not allowed on passenger flights. Ship via cargo or rent a unit at destination — consider destination rental or ground-forwarding options covered in the solar & battery strategies field guide.

Scenario C: Business traveler with two 120 Wh spare batteries

Outcome: Possible but only with airline approval. Request written approval ahead and bring documentation.

Advanced strategies for frequent travelers and digital nomads

Build a travel-specific power kit: One small 100 Wh max power bank, a 30W USB-C GaN charger, and a compact solar panel if you visit remote spots. This avoids the need to transport large stations.
Use airport rental & charging services: Many international airports now offer short-term power bank rentals or rentable “mobile power” lockers for multi-day stays — check rental options and portable power kits like those in our portable power & lighting kits review.
Pre-clearance via airline apps: In 2025–2026 more carriers added digital hazardous materials forms — use these to get approval before arriving at the airport; some carriers integrate with cloud services and tooling described in startup case studies such as Bitbox.Cloud for digital workflows.
Consider shipping ahead: For long-term stays, it’s often cheaper and less stressful to ship a heavy power station to your destination by ground freight rather than battle with airline rules.

What to do if you get stopped at the gate

Calmly present the Wh label and any email approvals.
If asked to remove the item, do so and carry it into the cabin if allowed.
If denied boarding for the battery, request the airline’s hazmat or customer service phone number and document the interaction (names, times).
Consider asking for immediate cargo-shipping alternatives with the airline or at the airport’s cargo office.

Final checklist — the 2-minute pre-flight battery audit

Are all spare batteries/power banks in your carry-on? Yes/No
Do all units show Wh? If not, did you convert mAh to Wh? Yes/No
Any unit >160 Wh? If yes, have you arranged cargo shipping? Yes/No
If any unit is 100–160 Wh, do you have airline approval in writing? Yes/No

Parting advice — protect your fare and your trip

Airline battery rules are non-negotiable safety measures. For deal-seeking travelers in 2026, the smartest move is to plan batteries into your travel budget—either by choosing airline-compliant power banks, renting a station where you land, or pre-arranging cargo shipping for large units. That keeps your cheap fare from turning into an expensive last-minute headache.

Quick action steps right now:

Open drawers and check each power bank for a Wh label.
Convert mAh to Wh if needed and mark units with a sticky label showing the Wh.
If any unit is 100–160 Wh, email the airline’s hazardous-materials contact and save the approval screenshot to your phone.

Resources & where to check next

Always confirm with your airline’s hazardous-materials or baggage policy pages and the departure country’s aviation authority. For expensive power stations, contact the manufacturer for recommended shipping methods and packaging tips.
