Choosing a charger
A single USB‑C charger that supports 30 W (or higher) covers most smartphones, tablets and the occasional laptop. Look for GaN (gallium‑nitride) models – they are smaller and stay cool.
If you travel to regions with 110 V or 220 V, the charger must be dual‑voltage (auto‑range). Most modern chargers are, but verify on the label.
Bring a short (1 m) cable for hotels and a longer (2 m) cable for airport lounges; both should be USB‑C to match most new devices.
| Feature | Recommended spec | Why it matters |
|---|---|---|
| Output | 30 W USB‑C | Fast charge for phones and many tablets |
| Voltage range | 100‑240 V | Works worldwide without a transformer |
| Size | GaN < 2 in | Fits in a small travel pouch |
Do
- Check the charger’s wattage rating; under‑powered chargers will charge slowly and may overheat.
- Keep the charger in your carry‑on bag to avoid loss in checked luggage.

Power bank basics
Airlines allow power banks up to 100 Wh in carry‑on; most consumer models list capacity in mAh, which you can convert (Wh = (mAh × V)/1000). A 20 000 mAh bank at 3.7 V equals 74 Wh, safely under the limit.
Choose a model with at least two USB‑C ports so you can charge a phone and a tablet simultaneously.
Some power banks support pass‑through charging, letting you charge the bank while it powers your phone – useful in airports.
| Capacity (mAh) | Approx. Wh | Typical phone charges |
|---|---|---|
| 10 000 | 37 Wh | ≈2 |
| 20 000 | 74 Wh | ≈5 |
| 30 000 | 111 Wh | ≈7 (check airline policy) |
Values assume a 4 000 mAh phone; actual results vary.
Do
- Charge the power bank fully before departure; a 100 % charge gives the longest runtime.
- Keep the power bank in an accessible pocket; you may be asked to show it at security.

Tracker selection
A Bluetooth tracker (e.g., Tile, Apple AirTag, Samsung SmartTag) helps locate luggage, backpacks or even a misplaced phone. They use a replaceable CR2032 coin cell that lasts about a year.
If you need global coverage, a GPS tracker with cellular service (e.g., Invoxia, Trak-4) can be placed in a suitcase; it requires a SIM or subscription plan.
Check local regulations: some countries restrict active GPS transmitters on aircraft; keep them in airplane mode during flights.
| Tracker type | Battery life | Coverage |
|---|---|---|
| Bluetooth (Tile) | 12 months | Local (phone‑to‑phone) |
| GPS (Invoxia) | 6 months (replaceable) | Worldwide with cellular |
Do
- Label the tracker with your contact info in the local language.
- Test the app and notification settings before you leave.
Questions people ask
Travel tech gear: what is the short answer?
Bring a 30 W USB‑C charger, a sub‑100 Wh power bank (20 000 mAh is a good balance), and a Bluetooth tracker; verify plug type for your destination.
Who does it apply to?
All international travellers who rely on smartphones, tablets or laptops for navigation, communication and booking, especially those on long flights or remote trips.
How much does it cost and how long does it take?
A 30 W GaN charger costs $30‑$60 (≈€28‑€55) and ships in 2‑5 days. A 20 000 mAh power bank is $40‑$80 with similar delivery. Bluetooth trackers range $25‑$35; they arrive in 3‑7 days.
Can I bring a power bank in checked luggage?
No. Power banks must be in carry‑on baggage; airlines prohibit them in checked bags due to fire risk.
Do I need a voltage converter for my charger?
Most modern USB‑C chargers are dual‑voltage (100‑240 V). If your charger shows a single voltage, use a small step‑down converter for 110 V destinations.
