Introduction

Portable power stations have become essential for camping, road trips, and emergency backup. The Anker 757 PowerHouse promises high capacity, fast charging, and durable LiFePO4 batteries. After spending a week with this unit, I’m ready to share my honest hands-on review.

Anker is a trusted name in charging accessories, but can their first large-format power station compete with established players like Jackery and Goal Zero? Let’s find out.

First Impressions: Build and Design

The Anker 757 PowerHouse is a beast. It weighs about 43 pounds (19.5 kg) and has a rugged, industrial design. The orange and black color scheme is distinctive and reminds me of professional-grade equipment.

The handle is sturdy and comfortable, making it easier to carry than its weight suggests. The casing is made of high-quality plastic with rubberized corners for drop protection. It feels durable enough for off-road adventures.

On the front, you’ll find a bright LCD screen that shows remaining battery percentage, input/output wattage, and estimated runtime. The interface is intuitive, with a single button to toggle the screen.

Ports and Connectivity

One of the standout features of the Anker 757 is the sheer number of ports. Let’s break them down:

• AC Outlets: 3 standard NEMA 5-15R outlets, each rated at 120V/15A (1800W continuous, 2400W surge). Pure sine wave output ensures safe use for sensitive electronics.
• USB-A: 2 ports, each 12W (5V/2.4A).
• USB-C: 2 ports, each 60W Power Delivery. Great for laptops and fast charging phones.
• Car Outlet: 1 port, 120W (12V/10A).
• Solar/AC Input: One combined input port for the included AC adapter or solar panels (up to 200W).

All ports are neatly arranged with clear labels. The USB-C ports support bidirectional charging, meaning you can use them to charge the power station itself, though only via the AC input.

Battery and Charging Performance

The Anker 757 uses a 1229Wh Lithium Iron Phosphate (LiFePO4) battery. This chemistry is safer and lasts longer than standard lithium-ion. Anker claims over 3,000 charge cycles to 80% capacity. That’s roughly 10 years of daily use.

Charging Options

• AC Wall Charger: The included 120W adapter charges the 757 from empty to full in about 14 hours. That’s slow compared to some competitors, but acceptable for overnight charging.
• Solar Charging: Up to 200W solar input. I tested with a 100W panel and got about 60W in full sun. Full charge would take around 16-18 hours with 100W, or about 8-10 hours with 200W.
• Car Charging: The 12V car charger provides up to 120W, but it’s not included.

One downside: the 757 does not support fast AC charging. Some rivals offer 500W+ AC charging for 2-3 hour full charges. But Anker prioritized battery longevity over speed.

Pass-Through Charging

The 757 supports pass-through: you can use the AC outlets while it’s charging. However, if you draw more than the input wattage, the battery will still discharge slowly. This is fine for trickle charging devices.

Real-World Testing

I used the Anker 757 for a weekend camping trip and as home backup during a power outage. Here’s how it performed.

Camping

I powered a 45W camping fridge, charged phones and laptops, and ran LED lights. The fridge ran for about 24 hours on a single charge, drawing around 50W average. That’s impressive.

The 757’s quiet operation (no fan noise unless heavily loaded) was a bonus. The LCD screen made it easy to monitor power usage.

Home Backup

During a 4-hour outage, I ran a 60W TV, a modem/router (15W), and charged phones. The battery dropped to 75%. It could easily handle a full day of essentials.

One issue: the 757’s AC outlets are not UPS-grade. There’s a 20ms transfer time when switching from AC to battery, so sensitive equipment may glitch. It’s fine for most devices but not for computers.

Comparison with Competitors

Key Takeaways:
– The Anker 757 offers the best battery longevity thanks to LiFePO4.
– It’s heavier than the Jackery but more powerful.
– The Goal Zero Yeti 1500X has higher solar input and output but costs more and uses less durable batteries.

Pros and Cons

Pros

• Long-lasting LiFePO4 battery (3000+ cycles)
• Pure sine wave AC output
• Multiple ports including USB-C 60W
• Clear LCD display
• Pass-through charging
• Rugged build quality

Cons

• Slow AC charging (14 hours)
• Heavy (43 lbs)
• No app connectivity
• Solar input limited to 200W
• No UPS feature for sensitive electronics

Frequently Asked Questions

How long does the Anker 757 PowerHouse last?
The Anker 757 has a 1229Wh capacity. For example, it can run a 60W fridge for about 18 hours or charge a smartphone 85 times. Actual runtime depends on device power draw.

Can the Anker 757 be used while charging?
Yes, the Anker 757 supports pass-through charging. You can use the AC outlets while it’s plugged into a wall or solar panel, though charging speed may slow under heavy load.

What type of battery does the Anker 757 use?
It uses Lithium Iron Phosphate (LiFePO4) batteries, known for safety and longevity. They last over 3,000 charge cycles, much longer than standard lithium-ion.

How long does it take to charge the Anker 757?
With the included 120W AC adapter, it charges fully in about 14 hours. Using a 200W solar panel, it can charge in 8-10 hours. The 757 supports up to 200W solar input.

Is the Anker 757 waterproof?
No, the Anker 757 is not fully waterproof. It has an IP rating of IP20, meaning it’s protected against objects larger than 12.5mm but not water. Keep it dry.

Conclusion

The Anker 757 PowerHouse is a solid portable power station that excels in battery longevity and build quality. It’s ideal for campers, van-lifers, and home backup users who value long-term reliability over fast charging.

However, its slow AC charging and heavy weight may deter some buyers. If you need fast AC charging or lighter weight, consider the Jackery Explorer 1000. But if you want a power station that will last for years without battery degradation, the Anker 757 is hard to beat.
