Power Bank Rules on Flights: What You Can (and Can’t) Bring

Introduction: Why Power Banks Are Strictly Regulated

Power banks are essential for travel.

But on airplanes…

👉 They’re treated as potential safety risks

Why?

👉 Because they use lithium-ion batteries

👉 And in rare cases, these can overheat or catch fire

That’s why airlines and authorities like the
👉 Transportation Security Administration
👉 Federal Aviation Administration
👉 International Air Transport Association

have strict rules.

The 2 Core Rules (Most Important)

According to WIRED and global aviation standards:

✔ Rule 1: Carry-On Only

👉 Power banks must be in your carry-on

👉 They are NOT allowed in checked luggage

This is confirmed by TSA guidelines:
👉 Check official TSA power bank rules

👉 Lithium batteries in cargo = fire risk (WIRED)

✔ Rule 2: Must Be Under 100Wh

👉 Maximum without approval: 100Wh

👉 This equals roughly:
👉 ≈ 27,000mAh

Anything above this:

• 100–160Wh → needs airline approval

• Over 160Wh → banned

(WIRED)

Why Airlines Use Wh (Not mAh)

This is where most people get confused.

👉 mAh = battery size
👉 Wh = actual energy (risk level)

The Formula

👉 Wh = (mAh × Voltage) ÷ 1000

Example:

• 20,000mAh → ~74Wh

• 25,000mAh → ~92.5Wh

• 27,000mAh → ~100Wh

👉 That’s why:

A 25,000mAh power bank is allowed—but 30,000mAh often isn’t

How Many Power Banks Can You Bring?

According to aviation guidelines:

👉 Up to 20 small batteries (<100Wh) may be allowed in theory
👉 Larger ones (100–160Wh) → usually max 2 units with approval

(WIRED)

⚠ But here’s the reality:

👉 Airlines can set stricter limits

👉 Some flights now restrict quantity or usage

Can You Use a Power Bank on a Plane?

This is where rules are changing.

👉 Technically: Yes, in many cases

BUT:

• Some airlines restrict usage

• Some require it to be visible

• Some ban charging during flight

(WIRED)

👉 Why?

Because of real incidents involving overheating batteries

Additional Safety Rules (Most People Don’t Know)

From aviation guidelines:

✔ Power banks must be:

• Undamaged (no swelling or cracks)

• Clearly labeled (Wh or mAh + voltage)

• For personal use only

✔ Extra precautions

• Store in protective pouch

• Avoid loose metal contact

• Don’t carry recalled products

(WIRED)

The Hidden Risk: Cheap Power Banks

Here’s something rarely explained:

👉 Not all power banks are equally safe

Lower-quality units:

• Lack temperature control

• Have unstable voltage

• Are more prone to overheating

👉 That’s why airlines care about battery quality, not just size

FAQ (SEO Long-Tail Section)

Can I bring a power bank on a plane?

Yes, but only in carry-on luggage and under 100Wh. (WIRED)

What happens if my power bank is over 100Wh?

You need airline approval (and may be limited to 2 units). 

Can I use a power bank during a flight?

Sometimes yes, but some airlines restrict usage. (WIRED)

Why are power banks banned in checked luggage?

Because lithium batteries pose a fire risk in cargo. (WIRED)

What is the safest power bank for travel?

One that is clearly labeled, under 100Wh, and built with safety protections (like iFORWAY).

Bottom Line

👉 Don’t guess the rules

👉 Follow the 100Wh standard

👉 And choose:

Power banks designed for real travel safety
