Buyer Questions
What's the best portable charger for travel?
The Anker 737 Power Bank (24,000mAh, 140W) handles laptops and phones and carries on any flight under the 100Wh limit — the best travel-focused power bank under $100.
Can I charge two devices at once?
Most portable chargers have 2+ ports; check total output wattage — a 20W charger split between two ports gives ~10W each, which is adequate for phones but not for laptops.
How do I know how many charges I'll get?
Divide the power bank's mAh by your phone's battery mAh (accounting for ~85% efficiency). A 10,000mAh bank charges a 3,300mAh iPhone about 2.5 times.
Are MagSafe power banks worth it?
For iPhone 12+ users, yes — snap-on MagSafe chargers eliminate cables for overnight or desk charging. The Anker 622 MagGo ($35) is the best-value MagSafe power bank.
