The kit that turns a café table or a hotel desk into a proper place to work, and the rules that catch people out: power banks on planes, and the plugs and voltage in every country we cover.
How we make money from this page. The Amazon links may earn us a small commission if you buy, at no cost to you. We picked these from the makers' own specs, not from who pays, and every product has a link to its maker. We don't show prices because they change every week.
Three things to check before you pack
Power banks go in your hand luggage, and 100Wh or less is safest. Never in checked bags. Up to 100Wh needs no airline approval; 100-160Wh needs the airline's approval, and IATA is removing that route for power banks from January 2027. Since 27 March 2026 the international rules allow two per person and ban recharging them on board. Some airlines and countries are stricter.
Many airlines now ban using them in flight. Emirates, Singapore Airlines, Qantas and Jetstar don't let you charge devices from a power bank on board, and Emirates allows only one. Check your airline's page before you fly.
Read the label on every charger. If it says INPUT 100-240V, it works anywhere with just a plug adapter. If it shows a single voltage, such as 230V, it needs a voltage converter in the US, Japan, Mexico, Colombia, Costa Rica and much of Brazil. Travel adapters change the plug, not the voltage.

South AfricaOlder buildings have the large three-round-pin Type M socket; new buildings since 2018 use Type N, which takes a two-pin European plug. Pack an adapter that does both.

A 99 g mouse that works on glass tables, which is half of all café tables.
99 g; 100.5 × 65 × 34.4 mm
Tracks on glass 4 mm or thicker
Bluetooth or Logi Bolt; USB-C charging
The catch: Small for big hands. Some locked-down work laptops need a Logi Bolt receiver, which comes with the For Business version but not the standard one.
Where there is a network socket, a cable is usually faster and steadier than crowded hotel Wi-Fi. UGREEN's 2.5G adapter works without a driver on Mac and recent Windows.
UGREEN 2.5G (25052): up to 2.5 Gbps
Plug and play on macOS, iPadOS and Windows 11
The catch: Fewer hotel rooms have a socket these days.
Laptops get stolen from café tables and bags go missing on transfers.
