Will the Clutch Pro last all day at a SXSW day?
Yes for most users. The 5,000 mAh Clutch Pro delivers about 1.2 full iPhone charges or 1.5 Galaxy charges. Pair it with a low-power mode hour and you'll easily clear 16+ hours of heavy use.
Is it MagSafe?
Yes — magnetic alignment with iPhone 12 and later. Snap and go, no cables needed for the phone-to-charger connection.
How fast does it charge my phone?
USB-C PD up to 20W out — about 50% on an iPhone in 30 minutes. MagSafe is closer to 7.5W; great for top-ups while you keep moving.
Is it TSA-approved for the flight there?
Yes. The Clutch Pro is ≈18.5 Wh (5,000 mAh × 3.7V) — well under TSA's 100 Wh carry-on limit and every major airline's per-bank cap.
