March Break Tech Part 1: Surviving Airport Security (Without Losing Your Gear)

Flying out of Pearson this March Break?

If you pack your tech wrong, airport security won’t just delay your family.

They may confiscate your gear.

Every year we see clients replacing perfectly good hardware because they didn’t know the travel rules.

Not because the device broke.

Because it was packed wrong.

The Dangerous Myth

“I’ll just pack my spare laptop battery or power bank in my checked luggage so I don’t have to carry it.”

Seems logical.

Until the X-ray machine flags it as a fire hazard.

⸻

The Expensive Reality

Lithium batteries in checked luggage are a major aviation risk.

If security finds one in a suitcase, they will open the bag, remove the battery, and dispose of it.

You’ll usually find a small notice explaining why it was removed.

But your $80–$200 battery is already gone.

⸻

1. The Power Bank Rule (100Wh Limit)

Lithium-ion batteries must stay in carry-on baggage or a personal item.

No exceptions.

Most airlines and security agencies limit these batteries to 100 watt-hours (Wh) without special approval.

For common brands like Anker or UGREEN, that equals roughly 27,000 mAh.

Anything larger — such as “camping” power stations or oversized power banks — may exceed airline limits entirely and won’t be allowed on the aircraft.

2. Airline Rules Can Vary

Government agencies such as CATSA set the baseline safety rules.

Airlines still control what boards their aircraft.

Air Canada and WestJet may allow slightly different configurations compared to discount carriers like Flair or Sunwing.

Before packing your gear, check the restricted items page for your airline.

It takes two minutes.

And it can save you hundreds of dollars.

3. Never Check Your Laptop

Technically, you can check a laptop if it is completely powered off.

But the straight truth?

You shouldn’t.

Cargo holds can reach colder temperatures at altitude, and baggage handling can be rough.

Between freezing conditions and impact damage, a checked laptop has very poor odds of arriving intact.

If the device matters to you, keep it in your carry-on.

⸻

4. Track Your Luggage (And the Kids)

Lost luggage is one of the fastest ways to ruin a vacation.

A small tracker such as an Apple AirTag, Samsung SmartTag, or Tile can tell you exactly where your bag is.

Even when the airline’s tracking app says “Location Unknown.”

Many parents also clip a tracker into a child’s backpack when visiting busy theme parks or tourist areas.

For about $40, it buys a lot of peace of mind.

⸻

The Bottom Line

Treat your tech the same way you treat your passport.

Keep lithium batteries in your carry-on.

Never check your laptop.

Track anything important.

A little preparation at home saves a lot of stress at airport security.
