Can I check my Kindle or e-reader?

Technically yes, as the lithium content is small, but it is highly recommended to keep it in your carry-on to prevent screen cracking.

Are hair straighteners allowed in checked bags?

Only if they are corded. If your straightener is cordless/rechargeable, it must be in your carry-on.

Is there a limit to how many power banks I can carry?

Most airlines allow up to two spares in your carry-on, provided they are under 100Wh each. Always check your specific carrier's rules.

Deciding What Electronics Go in Carry-On vs. Checked Luggage

Always keep devices with lithium-ion batteries, high-value electronics, and critical travel documents in your carry-on bag. Checked luggage is only for low-value, non-battery-powered items like charging cables, specialized adapters, or external hard drives that are heavily padded.

Check the battery type. If it has a lithium-ion battery, it must go in your carry-on. Airlines prohibit loose or installed lithium batteries in the cargo hold due to fire risk. This includes power banks, spare camera batteries, and portable chargers.
Assess value and fragility. If an item would ruin your trip if lost or broken (e.g., your primary camera body, your laptop for work, or your noise-canceling headphones), keep it with you. Checked luggage is subjected to rough handling and occasional theft.
Identify 'dummy' peripherals. Cables, wall bricks (without battery packs), power strips, and basic computer mice are safe to check. They are cheap to replace and don't pose a fire hazard.
Secure your storage media. External hard drives and SSDs should stay in your carry-on. Even if well-padded, the temperature shifts in a cargo hold can sometimes cause hardware failures in sensitive drives.
