Keep your work laptop light and carry a handheld for play. That one decision solves most of the problem, because a gaming laptop charges you in weight and battery every single day, including the many days you don't play.
The core kit
- A handheld. The Steam Deck OLED is the easy default at around 640 g. The full comparison is in Steam Deck vs ROG Ally vs Legion Go.
- A hard case. Sticks and screens don't survive loose in a backpack.
- A 65 to 100 W GaN charger that powers the handheld, the laptop and your phone, so you carry one brick instead of three.
- A microSD card for your library, so you aren't redownloading games on hotel wifi.
- Decent wired or Bluetooth headphones for shared rooms and night buses.
Worth adding if you stay for weeks
- A small USB-C dock and an HDMI cable, which turns most TVs into a big screen.
- A compact Bluetooth controller for that TV setup.
- A portable monitor if your rentals rarely have a usable TV.
Power on planes
Power banks and spare lithium batteries go in your carry-on, never in checked luggage. Up to 100 Wh is generally fine without approval, and 20,000 mAh banks usually sit under that limit. Between 101 and 160 Wh you need airline approval. Rules on using power banks in flight tightened during 2026 and vary by airline, so check your airline's page before you fly.
What to leave behind
Leave the full size mechanical keyboard, the desktop-style mouse pad, the second controller you never use and the capture card you might need one day. Every item has to earn its place in a bag you carry up stairs in the heat. I'd rather buy a cheap controller locally for a three month stay than carry one for three years.
Before you pick a city
Hardware is the easy half. If you play online, read how to check latency before you book, because no handheld can fix a bad route to your game's servers. The rest of the picture is in the gamer nomad guide.
