Anker 737 Power Bank Discounted During Prime Day

The high-output, large-capacity Anker 737 Power Bank (PowerCore 24K / A1289), rated at 140W, is on sale during Amazon's Prime Day event. In a June 23, 2026 article, U.S. outlet WIRED described the product as a personal go-to and said it has proven useful for camping and everyday use. The writer owns two units and is considering a third (WIRED).

The Anker 737, released around 2022–2023, was one of the early high-output power banks to deliver bi-directional 140W charging based on PD 3.1 (Power Delivery 3.1). With a capacity of 24,000mAh / 86.4Wh, it stays under the 100Wh limit for lithium batteries allowed on aircraft, making it popular for travel and outdoor use (Anker official). The unit features two USB-C ports and one USB-A port, delivering up to 140W from a single USB-C port and up to 18W via USB-A. It also carries an OLED smart display showing remaining charge, temperature, input/output wattage and charge cycles, a feature review outlet StorageReview praised alongside its compactness and durability (StorageReview).
