The Thoughtful Travel Tech Kit: What Earns Its Place
Most travel tech adds weight and anxiety. A good kit is small, rule-aware and built around four jobs: power, plugs, tracking and connectivity.
Travel tech tends to accumulate. A cable for every device, a charger for every cable and a gadget for every worry. The better test is whether an item solves a specific problem on a specific trip, and whether you understand the rules that apply to it before you reach the security line.
This kit is built around four jobs: keeping devices powered, plugging into the local socket, keeping track of your bag, and staying connected. Battery rules come first, because they are the part where a mistake costs you the item.
Power banks: read the rules first
The US Federal Aviation Administration's PackSafe page says spare lithium batteries, including power banks, must be carried in carry-on baggage only. If a carry-on is checked at the gate, the power bank must be removed and kept with you in the cabin. Battery terminals must be protected against short circuit, for example with tape, a case or a pouch.
The same page limits lithium-ion batteries to 100 watt-hours per battery. With airline approval you may carry up to two spare larger batteries in the 101 to 160 Wh range. It also notes that many airlines, domestic and international, may have stricter quantity or size rules, and shows how to calculate watt-hours by multiplying battery voltage by amp-hours.
Airlines can also restrict use. Emirates announced that from 1 October 2025 using any power bank on board is prohibited. Its release says customers may still carry one power bank under 100 Wh, but may not use it or charge it from the aircraft supply. That is one airline's policy, not a universal one, which is exactly why it is worth reading the rules of the carrier on your ticket.
Three items that earn their place
Anker MagGo Power Bank (10K, Slim)
Power bank
A slim 10,000 mAh bank is a modest top-up for a phone over a long travel day without becoming a brick in your pocket; Anker says about 5,500 to 6,500 mAh of it is usable. Magnetic wireless charging removes one cable from the kit. Anker's page is also candid that cell and circuit losses mean usable capacity is lower than the headline number.
Best for: Phone-first travellers who want a thin, low-profile reserve for transit days.
It is a phone-scale battery, not a laptop one, with a 30W maximum USB-C output on the page. The page does not show a watt-hour rating, so check the label before flying and confirm it is under your airline's limit. Magnetic wireless charging needs a compatible phone or case.
Ceptics 70W Universal Travel Adapter
Plug adapter with USB charging
One adapter with slide-out plugs for several socket types means one item instead of a bag of loose ones. Built-in USB-C and USB-A ports let you charge a phone and a laptop from a single wall socket, which also helps in hotel rooms with few outlets.
Best for: Multi-country trips where you carry a phone, a laptop and earbuds and want one charging point.
It is an adapter, not a voltage converter, and the manufacturer says so. It suits dual-voltage devices rated 100 to 240V, which includes most phone and laptop chargers, but devices that are not dual-voltage (check the label) would need a separate voltage converter. It supports plug types A, C, G and I, so check your destinations' socket types.
Apple AirTag (2nd generation)
Item tracker
A tracker answers a narrow question, which is where your bag is when the airline's information is thin. Apple's page notes that Find My can share an item's location with more than 50 airlines, which can help when you are discussing a delayed bag with an airline.
Best for: iPhone users who check a bag or want to find keys and a wallet.
It is built around Apple's ecosystem. The FAA says trackers in checked bags must meet its lithium limits and advises checking with the airline first; Apple's page lists a CR2032 coin cell but not its lithium content, so confirm the battery details. A tracker shows location, not retrieval, and an airline decides what to do with that information.
Staying connected: eSIM basics
Apple's support page explains that an eSIM is a digital SIM that lets you use a carrier plan without a physical card, and that you can add a local data plan when you travel abroad. It also notes that using two carriers requires the phone to be unlocked by your carrier, or both plans to come from the same carrier.
Before leaving, confirm that your phone model supports eSIM, that it is unlocked, and which plan you will use for roaming. The page itself lists a destination exception for mainland China, which is a reminder that eSIM support depends on the country and model. Check the details for your own phone and destination.
What to leave behind
- Duplicate chargers: one multi-port charger usually replaces three.
- Anything you only use at home, such as heavy peripherals.
- A second power bank, unless you have confirmed your airline allows it.
- Tech you have not tested together before the trip.
