Can you use a phone charger on a plane?

Power Up at 30,000 Feet: Navigating Airplane Charger Rules

The modern traveler relies heavily on their smartphone, tablet, or laptop. Staying connected and entertained during a long flight is practically essential, making the ability to charge devices a crucial consideration. But can you actually use your phone charger on a plane? The answer is largely yes, but with important caveats. Understanding these rules ensures a smooth and stress-free journey.

Most portable chargers are perfectly acceptable for use onboard aircraft, provided they meet specific safety regulations concerning battery capacity. The key figure to remember is 100 watt-hours (Wh). This is the maximum watt-hour rating for a lithium-ion battery – the type found in virtually all modern portable chargers – that can be carried onto a plane without any special permission.

Think of watt-hours as a measure of the battery’s total energy storage capacity. A higher watt-hour rating indicates a larger battery with a longer charging capability. While convenient, larger batteries pose a greater fire risk, hence the strict limitations.

What if your charger’s watt-hour rating is between 100 Wh and 160 Wh? In this instance, you’ll need to contact your airline before your flight. Airlines have varying policies, and pre-approval is necessary to avoid any issues at security checkpoints or during boarding. Don’t assume your charger will be permitted; always check directly with the airline.

Chargers exceeding 160 Wh are strictly prohibited from being carried in either carry-on or checked baggage. These are considered too hazardous for air travel. If you require such a high-capacity charger, alternative charging solutions should be planned for your trip.

How to find your charger’s watt-hour rating:

This information is usually printed directly on the charger itself, often alongside other technical specifications. If it’s not readily visible, check the product packaging or the manufacturer’s website. You might find it listed as Wh, Watt-hours, or even just as mAh (milliampere-hours) – in which case you will need to convert using the device’s voltage. Many online calculators are available to assist with this conversion.

In summary:

Before your next flight, take a moment to verify your portable charger’s watt-hour rating. Adhering to these simple rules ensures a trouble-free journey and allows you to keep your devices powered up, whether you’re catching up on emails, streaming movies, or simply staying connected with loved ones. Remember, it’s always best to err on the side of caution and contact your airline if you have any doubts.
