Hotel rooms often have insufficient outlets — one or two accessible, both behind furniture, none near bed. Small travel power strip plus one international adapter handles all devices easily.
What to pack
Compact power strip (3-4 outlets). International adapter (one good one). USB charging hub or multi-port USB cable. Total bag weight: under 200g.
Why this beats packing multiple adapters
One adapter on power strip, then UK plugs into strip. Works in any country. No specialised adapters needed for each device.
Total cost: £20-40. Repays in convenience on every trip.
