No-name 30,000mAh+ power banks from unfamiliar Amazon brands — These almost always overstate capacity by 30-50%, lack the UL or CE certification airlines require, and skip the thermal protection circuits that prevent fires. Real 30,000mAh capacity also exceeds the 100Wh FAA carry-on limit, which means you cannot fly with it. The $40 you save costs you a brick that fails in a year, gets confiscated at the gate, or worse.
1140W USB-C PD output that charges a 16-inch MacBook Pro to 50% in 28 minutes, with FAA-legal 86.4Wh capacity

3Three 100W USB-C ports plus a retractable USB-C cable - the no-cable-forgotten travel pick for multi-laptop households
4100W laptop charging at the budget end - the price-to-output value pick that r/HomeOffice keeps recommending

The FAA carry-on ceiling for spare lithium-ion batteries is 100Wh, which translates to roughly 27,000mAh at the typical 3.7V cell voltage. Power banks marketed at 27,650mAh and 25,000mAh sit just under this line by design - anything above 30,000mAh almost certainly requires airline approval and is regularly refused at the gate.
r/HomeOffice, r/digitalnomad, and r/macsetups consistently default to two recommendations: the Anker 737 for travelers who need 140W laptop charging and the Anker Prime 27,650 for users who want the highest capacity that still passes FAA. Threads asking for the budget answer keep returning to the INIU 100W 25,000mAh as the price-to-output value pick.
A laptop-capable power bank is a different category of product than the phone charger most people picture. The defining specs are USB-C Power Delivery output (65W minimum to keep a 13-inch laptop topped up, 100W or higher for a 16-inch MacBook Pro under load), capacity in watt-hours not just milliamp-hours, and FAA carry-on legality. The 100Wh ceiling matters more than buyers realize: anything over 100Wh requires airline approval and is often refused at the gate, and most 27,000mAh+ packs sit just under that line by design. Watch out for the marketing math: a 100W rating almost always describes a single port. Plug two laptops in and total output drops to a 65W plus 30W split, or sometimes lower. If you charge multiple devices, look for the multi-port wattage breakdown in the spec sheet, not the headline. For coffee shop work, prioritize fast input recharge over capacity - a power bank that takes 4 hours to refill is dead weight on a Sunday evening. Modern packs recharge in 60-90 minutes when paired with the right wall charger. Slim form factor matters in a laptop bag: the Baseus Blade, Anker Prime, and Anker MagGo lines are the slim-side picks; Anker 737, INIU 100W, and UGREEN Nexode 145W are brick-shaped and heavier. Built-in cables (Anker Laptop Power Bank, Anker 20K 87W) eliminate the cable you always forget. Smart-display models are worth the small price bump - knowing exactly how many minutes of charge are left beats guessing from a four-LED bar. Avoid no-name 30000mAh+ packs from unfamiliar brands on Amazon; they almost always overstate capacity, lack proper UL or CE certification, and skip the protection circuits that prevent thermal runaway. Anker, UGREEN, INIU, Baseus, Mophie, and Belkin all maintain the certifications and quality control to trust on a flight.

An adapter changes the plug shape; a converter changes the voltage. One check on your charger settles which you need — and which destroys appliances.
Hotel desks give you one socket. A flat-plug, non-surge travel strip fixes it — and surge protection is the feature you actively do not want abroad.
A 1500VA UPS is rated 900 to 1000 watts, not 1500, and its published runtime is only two points: half load and full load. Read both before buying.
