Who It's For

The Anker 737 is the power bank you buy when you are done with weak power banks. Its 140W USB-C output charges a 16-inch MacBook Pro at nearly full speed — something almost no other power bank can do.\n\nThe smart display shows exact wattage in and out for each port, remaining capacity, and time to full. Charging the bank itself takes just 52 minutes with a 140W charger.\n\nCapacity is 24,000mAh (86.4Wh) — the maximum allowed on airplanes. In our testing it fully charged a phone 4-5 times or added about 60% to a MacBook Pro 16.

Bottom Line

The best power bank for laptop users, period. If you work from cafes or travel often, it pays for itself in freedom.
