Anker 737 Power Bank Review: Is This 140W Beast Worth Carrying Everywhere?
You’ve probably been let down by a power bank before — slow charging, not enough capacity, or simply too bulky to carry. But if you’re searching for something truly powerful that can handle laptops, tablets, phones, and more, the Anker 737 Power Bank (PowerCore 24K) stands out as one of the most advanced, high-capacity portable chargers available right now.
This compact but beastly device pushes 140W of output via USB-C PD 3.1, which means it can even charge a MacBook Pro or a gaming laptop on the go. Its 24,000mAh battery capacity is optimized for tech professionals, digital nomads, frequent travelers, and mobile creators who rely heavily on fast and reliable charging.

From the moment you hold it, the premium build quality is apparent. It’s heavier than the average power bank (1.4 lbs), but it feels durable and solid. The digital screen on the front is a standout feature, showing real-time input/output wattage, charge/discharge cycles, and battery percentage. That alone puts it ahead of much of the competition in usability and control.
In performance tests, the Anker 737 Power Bank can charge an iPhone 15 Pro Max about five times or a 13-inch MacBook Pro once and a half before needing to recharge itself. It supports bi-directional charging — which means the same USB-C port can charge your device or the power bank itself at high speeds. Fully recharging the unit takes just under an hour and a half with a proper 65W–100W wall charger.

The Anker 737 Power Bank is not for everyone — but if you’re a power user or traveler who wants a premium portable charging solution that won’t let you down, it’s absolutely worth it. Between its 140W output, smart display, and solid build, it’s a top-tier tool. If you’re only looking to top up your phone now and then, you might be better off with one of Anker’s smaller models. But if you carry a laptop, tablet, and phone daily, this one delivers exactly what you need.
