T4 has an InMotion if your cable dies late.
This InMotion sits airside in Madrid-Barajas Terminal T4, so you’re fine on time if your boarding pass already says T4. Figure a 5–10 minute walk from most Schengen gates, longer if you’re coming from the far 40–50 gate area. It focuses on last-minute tech: headphones, power banks, travel plugs, and phone accessories aimed at the usual long-haul crowd through MAD.
Expect big-name brands at standard airport markups: think roughly €25–€40 for wired or basic Bluetooth earbuds and €30–€60 for power banks. You’ll find universal adapters that handle both US and UK plugs, useful if you’re crossing time zones on Iberia or American out of T4. Staff generally speak at least Spanish and English, sometimes a third language thanks to the international flows through Barajas.
Selection focuses on current phone models from Apple and Samsung, but they still carry generic USB-C and Lightning cables in the €10–€20 range. Over-ear noise-cancelling headphones sit higher, often over €150, so compare to what you’d pay at home before swiping. You can usually grab memory cards for cameras if Madrid is just a photography stop and you ran out of space overnight.
Stock turns over based on flight banks, especially around mid-morning long-haul departures from T4, so don’t assume they’ll have every color or model. Receipts print in euros, and cards are accepted without an issue. Tip: if you only need a basic charging brick, ask directly for the cheapest option; the first recommendation tends to be the higher-end brand.
