Introduction: Why Travel Tech Matters in 2025

Whether you’re navigating airports across Europe, working remotely from a Portuguese beach, or backpacking through Southeast Asia, the right technology makes travel smoother, safer, and more enjoyable. In 2025, our devices have become essential travel companions – from smartphones that serve as boarding passes to tablets that entertain during long flights.

But keeping those devices charged, connected, and trackable presents genuine challenges. A dead phone in an unfamiliar city isn’t just inconvenient – it can leave you without maps, translation apps, or emergency contacts. Lost luggage without a tracker means anxious waiting at carousels and complicated claims processes.

This comprehensive guide covers everything you need to stay powered and connected on the go. We’ll walk through essential travel tech categories, explain the technical details that actually matter, and help you build the perfect travel kit for your budget and travel style.

Who This Guide Is For:

Business travellers who need reliable power for laptops and phones
Holidaymakers wanting to keep devices charged for photos and navigation
Digital nomads working from cafes, co-working spaces, and hotel rooms
Backpackers seeking lightweight, budget-friendly solutions

Essential Travel Tech Categories

Before diving into specific recommendations, let’s establish the four core categories of travel tech you should consider. Think of these as the foundation of any well-prepared travel kit.

Power Banks and Portable Chargers

Power banks are arguably the most essential travel tech item. They provide backup power when outlets aren’t available – on planes, trains, buses, or simply during long days of sightseeing.

Key considerations:

Capacity: Measured in mAh (milliamp hours) – determines how many charges you get
Output power: Higher wattage means faster charging
Size and weight: Balance capacity against portability
Airline compliance: Must be under 100Wh for cabin luggage

For detailed recommendations, explore our Power Banks category (paid link).

Travel Adapters and Converters

Different countries use different plug types and voltages. European travellers need adapters when visiting the UK, US, or Asia. Non-EU visitors need the correct adapter for Type C and Type F outlets used across the continent.

Key considerations:

Plug compatibility: Match your destination’s outlet type
USB ports: Charge multiple devices without extra plugs
Voltage handling: Most modern electronics handle 100-240V automatically
Build quality: Cheap adapters can damage devices or pose fire risks

Compact Chargers

GaN (Gallium Nitride) technology has revolutionised travel charging. Modern compact chargers deliver laptop-level power from palm-sized devices, replacing the bulky bricks that used to dominate our luggage.

Key considerations:

Total wattage: Determines what devices you can charge
Port count: Multiple ports allow simultaneous charging
Size: GaN chargers are significantly smaller than silicon alternatives
Folding prongs: Essential for safe packing

Trackers and Tags

Luggage trackers have become increasingly popular since Apple introduced AirTags. These small devices help you locate lost or delayed baggage, providing peace of mind during connections and claims.

Key considerations:

Network type: Apple Find My, Samsung SmartThings, or Tile network
Battery life: Some use replaceable batteries; others are rechargeable
Size: Smaller is better for slipping into luggage pockets
Range: Depends on network coverage, not the device itself

Staying Powered on the Go

Understanding power bank specifications helps you choose the right device for your travel style. Here’s what the numbers actually mean.

Choosing the Right Power Bank Capacity

Power bank capacity is measured in milliamp hours (mAh). However, advertised capacity doesn’t equal usable capacity – energy is lost during conversion and transfer. Expect roughly 65-70% efficiency in real-world use.

Capacity guide:

5,000mAh: One full smartphone charge – pocket-sized for light users
10,000mAh: Two full smartphone charges – ideal for day trips
20,000mAh: Four smartphone charges or one laptop charge – suits longer journeys
26,800mAh: Maximum airline-compliant size – for heavy users and laptop charging

Pro tip: Consider your device’s battery size. An iPhone 15 has a 3,349mAh battery, so a 10,000mAh power bank provides roughly 2-2.5 real-world charges after efficiency losses.

USB-C vs USB-A: What You Need

USB-C is rapidly becoming the universal standard, especially in Europe where regulations now mandate USB-C on new devices. However, USB-A remains useful for older accessories.

USB-C advantages:

Reversible connector – no fumbling in the dark
Higher power delivery potential (up to 240W)
Single cable for phones, tablets, and laptops
Required on all new phones sold in the EU

Recommendation: Choose power banks and chargers with at least one USB-C port. Having one USB-A port as backup covers older devices like e-readers or wireless headphone cases.

Airline Regulations for Batteries

Airlines have strict rules about lithium batteries. Understanding these prevents confiscation and ensures hassle-free security screening.

Key rules for EU and international flights:

Under 100Wh: Allowed in cabin luggage without airline approval
100-160Wh: Allowed with airline approval (request in advance)
Over 160Wh: Not permitted on passenger aircraft
Checked luggage: Spare batteries and power banks are NOT allowed in checked bags

How to calculate Wh: Multiply mAh by voltage, then divide by 1,000. A 26,800mAh power bank at 3.7V equals 99.16Wh – just under the limit.

Fast Charging Explained

Fast charging standards can be confusing. Here’s what matters for travellers:

USB Power Delivery (PD): Universal fast charging standard – works with iPhone, Samsung, laptops, and most modern devices
Quick Charge (QC): Qualcomm’s standard – common on Android devices
Wattage: 18-20W charges phones quickly; 45-65W handles laptops; 100W+ charges multiple devices simultaneously

Recommendation: USB Power Delivery offers the best compatibility. A 65W PD charger handles virtually any phone or laptop you’ll travel with.

Travel Adapters for Europe and Beyond

Plug types vary significantly around the world. European travellers face different challenges than those visiting Europe. Here’s what you need to know.

EU Plug Types Explained

Continental Europe primarily uses two plug types:

Type C (Europlug): Two round pins – fits most European outlets
Type F (Schuko): Two round pins with grounding clips – used in Germany, France, and many other countries

The good news: Type C plugs fit into Type F outlets, so a single adapter often suffices for all of continental Europe.

UK to EU Adapters

The UK uses Type G plugs (three rectangular prongs), which are incompatible with EU outlets. British travellers visiting the continent need a UK-to-EU adapter – one of the most commonly needed travel accessories.

Options:

Simple adapter: Converts UK plug to Type C/F – compact and affordable
Adapter with USB ports: Adds charging capability – more versatile
Multi-country adapter: Works in UK, EU, US, and more – ideal for frequent travellers

Universal Travel Adapters

Universal adapters handle multiple plug types and include USB ports. They’re bulkier than single-purpose adapters but eliminate the need to carry multiple devices.

Features to look for:

Coverage for your destinations (EU, UK, US, Australia, etc.)
Built-in USB-C and USB-A ports
Safety certifications (CE marking for EU sale)
Surge protection for valuable electronics
Compact design that doesn’t block adjacent outlets

Voltage Considerations

Europe uses 220-240V; North America uses 110-120V. This matters for some devices:

Phones, tablets, laptops: Modern chargers handle 100-240V automatically – check the label
Hair dryers, curling irons: Often voltage-specific – may need a converter or dual-voltage model
Electric shavers: Usually work worldwide

Important: Adapters change plug shape; converters change voltage. For modern electronics, you typically only need an adapter.

Tracking Your Belongings

Luggage trackers provide peace of mind and practical benefits when bags go astray. Here’s how they work and what to consider.

AirTags and Alternatives

Apple AirTags work with the Find My network – over a billion Apple devices worldwide that anonymously relay location data. This makes them remarkably effective in populated areas.

Alternatives to consider:

Samsung SmartTags: Best for Samsung users – uses Galaxy Find network
Tile trackers: Platform-agnostic with growing network coverage
Chipolo: Works with both Apple Find My and Google networks

Recommendation: Choose a tracker compatible with your smartphone ecosystem for the best experience.

Luggage Trackers in Practice

Trackers shine during connections and delays. When your bag doesn’t appear at baggage claim, you can often see exactly where it is – still at your origin airport, on a different flight, or already at the airline’s lost luggage facility.

Best practices:

Place trackers inside checked luggage, not in external pockets
Use a protective holder to prevent battery drain from accidental activation
Enable notifications for when bags move
Consider two trackers for important luggage – redundancy helps

Privacy Considerations in the EU

Under GDPR, tracking devices raise privacy questions. Apple and Samsung have implemented anti-stalking features that alert people if an unknown tracker travels with them.

What this means for travellers:

Trackers in your own luggage are perfectly legal and appropriate
Anti-stalking alerts may trigger if you lend someone a bag with a tracker inside
Some older hotel luggage systems may generate false alerts
Airlines have no objections to luggage trackers

Packing Tips for Tech

Smart packing protects your devices and smooths your journey through security checkpoints.

Carry-On vs Checked Luggage

Always carry on:

Power banks and spare batteries (required by airline regulations)
Laptops and tablets
Cameras and expensive electronics
Anything irreplaceable

Can go in checked luggage:

Travel adapters (without batteries)
Charging cables
Wall chargers
Luggage trackers (that’s their purpose)

Organising Cables and Chargers

A dedicated tech pouch keeps everything accessible and prevents cable tangles:

Use elastic loops or mesh pockets to separate items
Coil cables loosely – tight coils damage internal wiring
Label cables if you carry multiples (coloured tape works well)
Keep frequently used items easily accessible

Airport Security Tips

Speed through security with proper preparation:

Laptops and large tablets usually require separate screening
Power banks may be inspected – keep them accessible
Organise your tech pouch so items can be shown quickly if requested
EU airports generally allow electronics in bags for standard screening

Common Travel Tech Mistakes

Avoid these frequent pitfalls that trip up even experienced travellers:

1. Wrong Adapter Type

The problem: Arriving at your hotel room with a UK plug and EU outlets – or vice versa.

The solution: Research your destination’s plug type before departure. When in doubt, a universal adapter covers all bases.

2. Power Bank Too Small (or Too Large)

The problem: A tiny 3,000mAh power bank that barely provides half a charge, or a massive one that weighs down your bag unnecessarily.

The solution: Match capacity to your actual needs. Most travellers find 10,000-20,000mAh ideal.

3. No Backup Charging Option

The problem: Relying solely on a power bank that depletes halfway through your trip.

The solution: Carry both a wall charger and power bank. Charge the power bank overnight so it’s ready for the next day.

4. Forgetting Cable Variety

The problem: Only packing USB-C cables when your headphones use micro-USB or Lightning.

The solution: Inventory all devices before packing. Consider a multi-tip cable or ensure you have the right cables for each device.

Frequently Asked Questions

Can I take power banks on planes?

Yes, but only in carry-on luggage. Power banks under 100Wh (approximately 27,000mAh) are permitted without airline approval. Larger power banks between 100-160Wh require airline permission. Power banks are never allowed in checked luggage due to fire safety regulations. Always check your specific airline’s policy before travelling.

What travel adapter do I need for Europe?

Continental Europe uses Type C and Type F plugs with 220-240V electricity. UK travellers need a UK-to-EU adapter. Visitors from the US, Australia, or Asia need adapters for their respective plug types. A universal adapter works for all origins and covers future trips to other regions.

Are AirTags worth it for luggage?

For frequent flyers, absolutely. AirTags provide real-time location data for checked luggage, helping you track delayed or misrouted bags. They’re especially valuable during connections and for identifying exactly where delayed luggage is located. The peace of mind alone is worth the modest investment for many travellers.

How many watts do I need for laptop charging?

Most ultrabooks charge effectively at 45-65W. Gaming laptops and larger workstations may require 100W or more. Check your laptop’s original charger wattage as a baseline. For travel, a 65W GaN charger handles most laptops whilst remaining compact enough for easy packing.

Do I need a voltage converter in Europe?

For most modern electronics, no. Phone chargers, laptop adapters, and camera chargers typically accept 100-240V automatically – check the label on your charger. You only need a voltage converter for devices specifically designed for a single voltage, such as some hair dryers and older electronics.
