TSA, Airlines and Big Batteries: What You Need to Know About Bringing E‑Bike Batteries, Power Stations and Robot Mowers on Trips

Hook: Bought a deal on an e‑bike, power station or robot mower — then hit a travel roadblock?

Holiday deal alert: you just snapped up an EcoFlow DELTA 3 Max or a Jackery HomePower 3600 Plus at a once‑in‑a‑season price, or picked up a Segway Navimow robot mower or a budget Gotrax R2 folding e‑bike. Great — until you realize these batteries don’t travel like your phone or laptop. Airline checkpoints and TSA now treat large lithium batteries as high‑risk items. If you plan to fly with a spare e‑bike battery, a portable power station, or a robot mower with a removable pack, knowing the rules can save you confiscation, fines, or a ruined trip.

The most important rules — read first

Bottom line: spare lithium batteries are generally allowed only in the cabin (carry‑on), not checked baggage. Batteries up to 100 Wh are allowed without airline approval; batteries between 100 Wh and 160 Wh can be carried in the cabin but usually require airline approval; batteries over 160 Wh are effectively prohibited on passenger aircraft and must be shipped as cargo under dangerous‑goods rules.

Those thresholds are the foundation of airline and TSA policy worldwide. If your recent deal includes a product with hundreds or thousands of watt‑hours (for example, Jackery HomePower 3600 or EcoFlow DELTA Pro/3 models), you will not be able to bring it on a passenger plane. Plan ahead.

Why this matters in 2026

• Demand for off‑grid gear surged in 2023–2025; by late 2025 many carriers tightened on‑the‑spot enforcement after several lithium battery incident reports.
• Airlines and airports have expanded screening and fines; some airlines now refuse to transport certain large battery products at all.
• Shippers and cargo operators have introduced more accessible options for moving large batteries, but that requires extra time and cost.

Quick definitions and how to check capacity

Watt‑hours (Wh) is the unit you must use. If the battery label shows volts (V) and milliamp‑hours (mAh), convert: Wh = (mAh / 1000) × V. If the pack only lists mAh, look up the nominal voltage before converting.

Examples (illustrative):

• A 36 V, 10 Ah e‑bike battery = (10,000 mAh / 1000) × 36 V = 360 Wh (over limit)
• A laptop battery ~50 Wh (OK for carry‑on)
• Jackery HomePower 3600 = ~3600 Wh (far above passenger limits; cargo only)

How TSA and airlines treat different battery types

Lithium‑ion batteries (rechargeable) are the most common in e‑bikes, power stations and robot mowers. They present thermal runaway risks if damaged or shorted.

TSA / FAA / IATA general approach (practical summary):

• Spare lithium batteries (including power banks and removable e‑bike packs): Carry‑on only. No spares in checked baggage.
• Batteries installed in equipment (embedded in the device): Often allowed in carry‑on or checked, but airlines prefer devices with batteries to travel in the cabin.
• Capacity limits: ≤100 Wh — allowed without airline approval; >100 Wh and ≤160 Wh — allowed in cabin with airline approval; >160 Wh — not permitted on passenger aircraft (cargo transport only under dangerous‑goods rules).
• Terminal protection: exposed terminals must be protected from shorting (tape, original packaging, insulating caps).

Real‑world examples tied to recent deals

Use the recent Green Deals landscape as a shopping/practical test case:

• Jackery HomePower 3600 Plus: The 3600 Wh nominal capacity makes this a cargo/hazardous goods shipment — not a candidate for checked or carry‑on. If you bought one at the exclusive sale price, arrange freight shipping or local pickup.
• EcoFlow DELTA 3 Max and DELTA Pro 3: These portable power stations often exceed 1000 Wh. Same rule: freight only for air transport. For short trips, rent or ship to your destination ahead of arrival — see guides for preparing portable creator gear and coordinating local delivery.
• Segway Navimow robot mowers: The mower body itself may be allowed, but the battery pack is the issue. If the battery is removable and under 160 Wh (some small mower packs are), you may carry it in the cabin with airline approval if needed. Most full‑size mower batteries exceed the limits and must be shipped.
• Gotrax R2 folding e‑bike: Budget commuter e‑bikes often have packs from ~200–500 Wh. That places most of them above the 160 Wh threshold — they can't fly as spare batteries. If the battery is removable and under the limit (rare), follow airline approval rules and cabin carriage.

Step‑by‑step: How to avoid confiscation or fines

1) Before you buy (or accept a deal)

• Check the battery label or product page for Wh. If only mAh and voltage are listed, calculate Wh.
• If Wh > 160, plan a non‑passenger transport method (ground courier or cargo freight). Do not expect a commercial passenger flight to accept it — consider ground courier or a specialist forwarder.
• If Wh is 100–160, check your airline battery policy then call to request advance approval in writing. Keep that email or reference number.

2) Packing and preparing for the airport

• Always pack spare lithium batteries in your carry‑on. That includes extra e‑bike batteries, power bank modules, and spare mower cells.
• Insulate terminals: cover exposed positive terminals with tape, use original boxes, or use terminal caps to prevent short circuits.
• Bring documentation: battery spec sheet or product manual showing Wh, and proof of airline approval if granted.
• Protect installed batteries: if the battery is installed in equipment (e.g., a robot mower), drain some charge — many airlines prefer partially charged batteries — and secure device against accidental activation.

3) At the airport and at security

• Declare large batteries to the airline and to TSA checkpoint staff when asked. Be proactive: explain you have a spare battery and present the spec sheet.
• Expect additional screening for anything >100 Wh. Allow extra time at the airport.
• Do not check spare batteries in checked baggage or gate‑checked items. If an airline attempts to move one to checked baggage, insist on written policy or refuse — then call the airline’s hazardous goods / dangerous goods desk.

Shipping large batteries: realistic options

If your deal includes a battery >160 Wh, you have three practical choices:

1. Ship ground courier (best for domestic moves): UPS Ground, FedEx Ground and similar services handle many lithium batteries but require proper packaging and declarations. Some carriers restrict air transport for large lithium batteries and will route ground shipments accordingly.
2. Use a specialized dangerous‑goods freight forwarder (best for international or heavy units): They handle proper labeling, UN packaging, and ICAO/IATA/IMDG compliance. This is the usual route for power stations like Jackery and EcoFlow if air cargo is required.
3. Have it delivered to your destination before travel: Arrange for the retailer to ship to your hotel or a local pickup point so you don’t have to move the battery by air yourself.

Tip: freight and special handling add cost. When a product is deeply discounted, include shipping and potential hazmat surcharges in your total cost calculation.

Airline policy nuances and recent 2025–2026 shifts

Since late 2024 and into 2025, multiple carriers increased spot checks and clarified language around batteries between 100–160 Wh. By late 2025 some major carriers began actively refusing to accept certain consumer power stations for transportation on passenger aircraft at check‑in. In 2026, expect stricter gate enforcement and greater probability that agents will confiscate oversized spare packs rather than attempt to rebook them as cargo.

What that means for travelers:

• Verbal assurances aren’t enough — get documented airline approval for 100–160 Wh packs.
• If an airline's website is vague, call the hazardous materials / dangerous goods desk at least 48 hours in advance.
• Keep receipts and screenshots of product specifications to quickly prove the battery’s Wh rating at security.

Robot mowers and e‑bikes: special considerations

Robot mowers

Many modern robot mowers ship with removable lithium battery modules. If the module is small (≤160 Wh) and removable, you can likely carry it in the cabin with airline approval. Larger built‑in packs will be treated as hazardous goods.

• Remove the battery before travel when possible.
• Secure the mower so it cannot power on in the cargo hold (remove blades, if removable; use physical locks).
• Check local ground shipping rules — some mower manufacturers partner with logistics providers for safe shipment or local delivery services that work with yard‑service retailers and event teams.

E‑bikes

E‑bike batteries are the most frequent cause of travel headaches. Most consumer e‑bike packs are between roughly 200–700 Wh — too large for passenger planes. Folding commuter e‑bikes with small packs are an exception, but verify Wh before you fly.

• If you must fly with an e‑bike: remove the battery (if removable), ship it separately via approved cargo, or rent an e‑bike at your destination.
• Some bike rental and transport services will handle battery shipment and reinstallation; that’s often faster than coordinating airline acceptance.

Case study: What happens if you try to carry a Jackery or EcoFlow onboard

Scenario: You buy a Jackery HomePower 3600 during a flash sale, then try to bring it to a weekend cabin trip by plane. At check‑in the agent sees the unit’s weight and label. Because the pack’s capacity far exceeds 160 Wh, the airline will either:

• Refuse acceptance for the flight and require you to ship the unit as cargo, or
• Confiscate the battery at the airport (leading to loss of the battery or delayed return), or
• Require you to remove the battery and ship it — same outcome but with an extra step and cost.

Practical lesson: if the product exceeds passenger limits, don’t assume you'll be able to
