Will the Clutch Pro last all day at an ACL 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.
