Buy the Anker A1383 Power Bank.

Twice the capacity and far more output means it covers trips the other two simply can't.

What was compared

1. Covers a full day, not just a top-up
20000mAh against the INIU's 10000mAh and the MagSafe charger's 5000mAh means multiple full phone charges, not one partial top-up. On a long travel day the smaller two tap out before you get home, the Anker doesn't.
2. Charges a laptop, not just a phone
87W across three ports means the Anker can actually run a MacBook, where the INIU's 45W and the MagSafe bank's 20W are phone-only numbers. If you ever travel with a laptop, this is the only one of the three that helps.
3. Three devices at once beats one
The Anker's 3 ports let you charge your phone, earbuds and a tablet together; the INIU and MagSafe bank are single-device chargers. Group travel or a bag full of gadgets makes this the real difference, not a spec footnote.
4. Reviewers call it their daily driver
Owners describe running it as their main charger for months, citing reliable pass-through charging and a digital percentage readout. That kind of everyday trust matters more than a lower price tag that buys less battery.
5. Yes, it costs more. Buy it anyway.
At $69.99 against $23.99 and $30.62, the Anker is the priciest pick, but it is also double the capacity of the INIU and four times the MagSafe bank's, plus laptop charging neither offers. Unless you only need a quick phone top-up on short trips, the extra capacity pays for itself fast.
