Prime Day Pricing Context
Strampe noted that the current Prime Day price is "close to the best price I’ve tracked." The power bank has dropped lower in the past, but not since last Black Friday. This makes the sale an attractive opportunity for those needing a reliable high-capacity power bank for travel or field work.
Practical Applications for Industrial Professionals
While designed for consumer use, the Anker 737 can serve industrial procurement managers and field technicians who require portable power for laptops, test equipment, and multiple devices in remote locations. Its fast recharge capability (under one hour) and high wattage (140W) make it suitable for short turnaround during field operations or offsite projects.
Availability
The sale is part of Amazon's Prime Day 2026 event. Strampe mentioned she originally purchased the Anker 737 for camping, needing something reliable to charge multiple gadgets simultaneously without being too bulky. She has since purchased a second unit after misplacing the first, and is considering a third at the current price.
"This brick has a whopping 24,000-mAh capacity and can send or receive up to 140 watts," Strampe wrote. "My favorite feature is that the power bank itself can be recharged in under an hour."
The only downside noted is the weight—about 1.5 pounds—but the upsides are numerous enough for Strampe to recommend it as an everyday carry item.
For manufacturing and industrial readers, this power bank represents a potential procurement item for teams that need reliable off-grid power. The combination of high capacity, fast recharge, and multi-device support addresses common pain points in field service, remote inspection, and temporary worksites. The Prime Day discount lowers the cost per watt-hour, making it a cost-effective choice compared to lower-spec alternatives.
