Best portable charger for a transatlantic crossing.
Seven sea days in a row. Cabin outlets are precious. Your phone needs a pocket-sized solution.
Sea days, scarce outlets.
QM2, NCL Joy, MSC repositioning — transatlantic itineraries pile up sea days in a row. Cabin outlets are scarce. You're using your phone all day for Kindle, photos, music in the gym, FaceTime home when the Wi-Fi's good.
Power bank > extra wall charger.
One outlet covers all
Charge the power bank overnight, top up everything from it during the day.
MagSafe everywhere
Snap to your phone on a sundeck lounger or at the gym treadmill.
TSA-friendly
≈18.5 Wh clears every airline's per-bank cap for the flight home.
Limited shore stops.
Many transatlantic itineraries skip ports altogether or have just 1–2 stops in the Azores, Madeira, or the Caribbean. The Clutch Pro is the workhorse for sea days; saves your sanity at port days where outlets are even harder to find.
15 colors, one for every dinner.
Formal nights matter on transatlantic crossings. The Clutch Pro's matte finish disappears into a tux jacket or evening clutch — slim enough to forget about.

The matte finish hides fingerprints, scuffs, and whatever happens after a long day.
Seven sea days, one charger.
Slim, magnetic, ≈18.5 Wh — the Clutch Pro keeps your phone alive through every transatlantic sea day moment.
