Best Portable Charger for London Travel in 2026
Tube map lookups, contactless tap-ins, Tower Bridge photos, double-decker bus tours. Why the Clutch Pro is built for London days.
The Clutch Pro is the perfect London travel companion.
London runs on your phone — Citymapper for the Tube, contactless tap-in for the Underground (your phone is your Oyster card), photos at Tower Bridge and Buckingham Palace, and reservations for everything from Borough Market to the West End. The Clutch Pro slim fits a Barbour jacket pocket or small crossbody; the built-in USB-C cable removes one dongle from your travel kit; and ~1.3 full charges covers a full London day with heavy Tube use. Bring a Type G adapter to recharge the Clutch at your hotel.
What matters.
Type G plug compatibility
UK uses Type G (3-pin square) outlets. Bring a Type G or universal travel adapter to recharge the Clutch.
TSA-approved for the British Airways flight
~18.5 Wh, well under TSA's 100 Wh limit. Approved on BA, Virgin Atlantic, American, and every airline flying to LHR, LGW, or STN.
Contactless tap = constant battery
Using your iPhone as an Oyster card means screen-on every Tube ride. The Clutch keeps you tapping in all day.
The classic London walk.
Big Ben, Westminster Abbey, walk across Westminster Bridge to the London Eye, South Bank to Tower Bridge. 15,000+ steps, dozens of photos, multiple Tube changes. Pack the Clutch in your jacket pocket and snap-charge as you walk.
Indoor heavy phone day.
Three hours in the British Museum (free entry, but the app is essential), lunch in Covent Garden, shopping along Long Acre. The museum's app drains battery — the Clutch keeps your iPhone alive for the Tube ride back.
Train day = phone-heavy day.
30-minute train to Windsor or 90 minutes to Bath. Trainline app, Google Maps walking the towns, dozens of castle/Roman bath photos. The Clutch in your day bag handles the round trip easily.
Markets, music, river days.
Camden Market in the morning, DLR to Greenwich for the Royal Observatory and Cutty Sark. Walking-heavy, photo-heavy day. The Clutch keeps your iPhone above 50% all the way through Greenwich Park.
15 colors. Pick yours.
The matte finish hides fingerprints, scuffs, and whatever happens after a long day.
