The Anker 757 Power Station is a high-capacity portable power station designed to provide reliable power anywhere. With a mammoth 1229Wh lithium iron phosphate battery, this power station packs enough juice to charge phones over 100 times, drones over 25 times, and even run small appliances.

What makes the Anker 757 truly stand out is its rugged build and long-lasting battery. The sturdy metal and plastic exterior is built to withstand the elements, while the upgraded battery chemistry allows over 3,000 charge cycles. This means you can use and charge the station daily for over 8 years before noticeable battery degradation.

In this review, we’ll take an in-depth look at the 757’s battery performance, power output, charging speeds, and real-world usage powering everything from fridges to drones. You’ll see why this beefy power station is in a class of its own when it comes to off-grid power. With high capacity reserves and strong enough output to run power tools, this station provides the ultimate portable power.

Battery Chemistry – The Standout Feature

What makes this power station so different and powerful compared to others on the market is its advanced lithium iron phosphate battery chemistry. Unlike most power stations and consumer electronics which use lithium ion batteries rated for 500-800 cycles, the Anker 757 utilizes lithium iron phosphate batteries rated for over 3000 cycles.

To understand why this is significant, it’s important to know how batteries degrade over time. Each full discharge and recharge puts wear and tear on a battery, lowering its maximum capacity. After 500-800 of these charge cycles, a typical lithium ion battery will only hold 80% of its original capacity. However, the 757’s lithium iron phosphate batteries are rated for upwards of 3000 cycles before reaching that 80% threshold.

For perspective, let’s say you fully drained the battery every single day, then recharged it to 100%. At one cycle per day, it would take over 8 years to reach 3000 cycles before seeing degradation. That kind of longevity for a high capacity portable power station is remarkable. On top of that, Anker provides a 5 year warranty on the 757’s batteries, demonstrating their confidence in the product’s durability.

The advanced battery chemistry allows this power station to withstand consistent heavy usage over many years. It’s a key factor that separates it from competing options. While the port selection, output capacity, and build quality are all impressive in their own right, it’s the 3000+ cycle lithium iron phosphate battery that really makes this model stand out.

Build Quality

This power station is one heavy unit as the amount of energy the batteries can store is massive. However, the exterior shell makes it easy to cart around with the two handles at the top that are reinforced by an aluminum frame. All the gray accents around the edges are metal while everything else is constructed of a high quality plastic. The look of the power station is also really badass with blue accents on the vents and of course the two-tone color between the aluminum and plastic.

There are also big rubber feet on the bottom to keep the power station in place during travel and protect the surface that it’s sitting on. The 757 is built like a tank – there’s no bending, bowing, or creaking in the body. The aluminum frame keeps everything together and makes it feel rigid. This rugged construction is important because the power station will likely be brought outside on camping trips, thrown in the back of a truck bed, and maybe even brought onto construction sites. The 757 is built to withstand abuse during transport and heavy use in the field. The sturdy aluminum and plastic shell reinforced by the metal frame allows it to take a beating while the handles and rubber feet make it easy to move around and keep stable.

Display & Ports

The 757 power station has an informative display that shows critical power metrics and battery information. This allows you to monitor the power station’s status at a glance.

Specifically, the display shows input power, output power, charge mode, active ports, remaining charge time, remaining battery capacity, temperature alerts, and power saving mode. There are also buttons next to the display to turn on the backlight and enable power saving mode.

In terms of output ports, the 757 is equipped with a variety of options:
