Packing
Power banks and lithium batteries on flights
Power banks and spare lithium batteries belong in carry-on — not checked luggage — on virtually all airlines. Capacity limits usually cap at 100Wh (about 27,000mAh at 3.7V) per battery without airline approval; loose spare batteries need terminal protection. Rules tighten over time — read your carrier's dangerous-goods page before packing multiple bricks for a long trip.

General rules
- Power banks in carry-on only — checked bags with lithium are rejected or removed.
- 100Wh per device is the common airline threshold — label may show Wh or mAh.
- Spare batteries taped or in original case — terminals covered.
- One or two banks per person is typical; large quantities raise security questions.
Devices with built-in batteries
Phones, laptops, cameras, and e-readers stay in carry-on when possible. Airlines occasionally ban specific recalled models — check aviation authority notices. vape devices often have stricter rules — verify carrier policy.
Before you fly
Airline and airport security have final say — rules differ slightly by country. Estimates only; confirm on official airline dangerous-goods pages and airport security guide.

Beach trip packing
Beach trips need sun protection, two swim options, cover-up for shops and sun, and sandals that handle sand and short walks — buy bulky sunscreen and aloe at destination when allowed to save weight. Pack a dry bag for phone and book; leave expensive jewelry home. One light outfit for evening dining beats five resort outfits you never wear.
Checked bag vs carry-on only
Carry-on only saves time at baggage claim and eliminates most lost-luggage anxiety — but it forces laundry and limits liquids. Checked bags make sense for two-week winter trips, family gear, or destinations where you need more than the cabin allows. Compare airline checked-bag fees against buying toiletries and an extra shirt at destination.
Laundry while traveling
Trips longer than a week need a laundry plan: hotel service is convenient but pricey, local laundromats are cheapest in many countries, and sink washing works for underwear and quick-dry shirts if you pack detergent sheets. Wear merino or synthetics that dry overnight and you carry half the clothing.
Power adapters and voltage abroad
Most phone and laptop chargers are dual-voltage (100–240V) and need only a plug adapter for the country shape. Hair dryers and cheap appliances often are not — either buy a travel dual-voltage model or use hotel hair dryers. One universal adapter plus a small power strip covers most trips; verify plug type for your destinations before you pack.
Travel checklist before you leave home
Run this checklist from one week out through departure morning: confirm documents and bookings, prep your home, set up your phone for abroad, pack essentials in carry-on, and do a final 24-hour pass so nothing critical stays on the kitchen counter.
Winter travel packing
Cold trips need a layering system — base, insulating mid, waterproof shell — not five heavy sweaters. Wear the bulkiest coat and boots on the plane; pack thin merino layers that wash fast. Hats and gloves cost little to buy if forgotten but ruin days if your ears freeze on day one.
