MagSafe Battery (Wireless)
Anker MagSafe Battery Pack 5K ($50) — snaps to iPhone 12+ back. Adds ~50% battery wirelessly. Slim profile.
Apple's MagSafe Battery ($99) — same idea, but charges via Lightning (or USB-C on newer revisions). 1.4 full charges.
Recommend Anker over Apple's: half the price, similar performance.
Pocket Power Bank (Light Travel)
Anker Nano Power Bank 5K ($25-$35) — palm-sized, plugs directly into iPhone via USB-C. No cable needed.
5K = ~1 full iPhone charge. Best for: errands, day trip, in case battery dies.
Multi-Day Power Bank (Big Trips)
Anker Power Bank 737 24K mAh 65W ($130) — 6 full iPhone charges OR charge MacBook via USB-C 65W. Heavier but lasts days.
Best for: 3-day camping, week-long travel where outlets aren't reliable, conference attendees with long days.
Best Value Big Power Bank
ZMI 20K mAh ($70) — 5 iPhone charges, USB-C PD 18W output. Cheaper than Anker 737 but 4K mAh less.
Best if: budget-conscious, don't need MacBook charging.
MagSafe vs Wired (Speed)
MagSafe wireless: 7.5W to iPhone (slower). Wired USB-C PD: up to 27W to iPhone. Wired charges 3x faster.
If you have time = MagSafe magic. If you need charge fast = wired USB-C.
Avoid
- Sub-$15 power banks — capacity often false-advertised
- USB-A only banks — slower than USB-C, dying tech
- Power banks without USB-IF certification
- 'Wireless' power banks that aren't true MagSafe (Qi at 5W = slow)
Air Travel Restrictions
Power banks must be in carry-on (NOT checked baggage). Lithium-ion fire risk. Most airlines: under 100Wh OK without notification, 100-160Wh with airline approval, over 160Wh prohibited.
Anker 737 (24K mAh, ~88Wh) = under 100Wh = no airline issue. ZMI 20K = ~74Wh = fine.

- Daily carry: Anker MagSafe 5K ($50) in bag
- Travel: Anker 737 24K 65W ($130) — also charges MacBook
