Portable tech is where marketing units do the most damage. A power bank advertised as “30,000mAh” doesn’t tell you how many laptop charges you’ll get, and a “huge capacity” power station may be banned from your flight. The spec that matters on the move is the real one: watt-hours, airline limits, and whether it connects where you’re going.
This hub maps the gear people pack first and names the deciding number for each. We translate the marketing into what you actually get – real charges, real run-time, real legality – so you buy the thing that works at the campsite, the gate or the client site, not the one with the biggest box number.
- Need to charge a laptop on the go? A laptop power bank rated in watt-hours and USB-C PD wattage, not just mAh.
- Power for camping or outages? A portable power station sized by watt-hours and output watts.
- Working away from a desk? A portable monitor and mobile Wi-Fi turn anywhere into an office.

What should you pack for power and work on the go?
Match the gear to the trip – one real number, not the marketing, decides it.
Decider: watt-hours and USB-C PD wattage (e.g. 100W) – that, not mAh, sets real laptop charges.
Decider: watt-hour capacity and continuous output watts, plus whether it is airline-legal to carry.
Decider: USB-C single-cable power and video, and a weight you will actually carry.
Decider: the bands and carriers it supports where you are going, not just the headline speed.
Laptop power banks
To charge a laptop a power bank needs USB-C Power Delivery at enough wattage (often 65-100W) and real watt-hour capacity – the mAh number alone is meaningless across voltages. Check the Wh rating against the 100Wh airline cabin limit. See our laptop power bank guides.
Portable power stations
A power station is sized by two numbers: watt-hours (how much energy it stores) and output watts (what it can run at once). Match both to your devices, and check airline rules – most stations are too large to fly with. Start with the power station guides.
Portable monitors
A portable monitor that takes power and video over a single USB-C cable is the difference between a usable travel desk and a tangle. Weight and brightness matter more than resolution. The portable monitor guides have the picks.
Mobile Wi-Fi
A mobile hotspot or 5G router keeps you online where there’s no trusted Wi-Fi – and as a backup when home broadband drops. What decides it is the bands and carriers it supports in your region, not the peak speed. See the mobile Wi-Fi guides.
Travel workstation
A travel workstation is the kit that turns a laptop into a real desk anywhere: a stand, a compact keyboard, a hub and a portable screen. The travel workstation guides show how to pack a productive setup light.
Two-way radios
When there’s no cell signal – hiking, events, work sites – two-way radios just work. Range claims are optimistic; terrain decides real range. Our two-way radio guides cover licence-free and licensed options.
Drones
For a drone, the deciding factors are flight time, camera stabilisation and the local rules you must follow. Weight class determines what registration and restrictions apply. See the drone guides.
How to choose portable tech without overspending
First, read the real number, not the marketing one. Watt-hours and output watts tell you what a battery actually does; mAh and “fast charge” don’t. Second, check it travels. The best power station is useless if it can’t board your flight – confirm the 100Wh cabin limit and local rules before you buy. Buy for the trip you actually take.
Where to start with portable tech
Start from the trip. A commuter needs a USB-C PD power bank; a camper needs a watt-hour-rated power station; a remote worker needs a portable monitor and mobile Wi-Fi. Name the journey, match the real number, and skip the capacity you’ll never use.
Frequently asked questions
Why does mAh not tell me how many laptop charges I get?
Because mAh is measured at the battery’s internal voltage, not your device’s. Watt-hours (Wh) are the honest measure of stored energy. To charge a laptop you also need enough USB-C Power Delivery wattage – look at Wh and PD watts, not mAh.
Can I take a power bank or power station on a plane?
Power banks up to 100Wh are generally allowed in carry-on (never checked). Most large power stations exceed the limit and cannot fly. Always check the Wh rating on the device and your airline’s current rules before travelling.
What size power station do I need?
Add up the watts of what you will run at once (output watts) and how long you need it (watt-hours). A few device top-ups needs far less than running a fridge during an outage. Buy for your real load, not the biggest number.
Do portable monitors need their own power?
Many run on a single USB-C cable that carries both power and video from your laptop, which is the most convenient option. Brighter or larger models may need a separate power supply. Check single-cable USB-C support before buying.
Is mobile Wi-Fi better than tethering my phone?
A dedicated hotspot or 5G router usually gives better battery life, range and multi-device support than phone tethering, and keeps your phone free. For occasional use, tethering is fine; for regular remote work or as broadband backup, a dedicated device wins.
Do I need a licence to fly a drone or use a radio?
It depends on weight and band. Many drones require registration above a small weight threshold, and some two-way radios need a licence while others are licence-free. Check your country’s rules before you fly or transmit.
