The rapidly growing portable power station market has seen the release of many new products in recent years that aim to provide reliable off-grid power. Two of the most popular options are the Ecoflow Delta Pro and the new Anker Powerhouse 767. Both offer large battery capacities and the ability to recharge via solar panels, making them ideal for outdoor adventures and emergency backup power.
In this post, we’ll take an in-depth look at how these two premium battery generators compare across a range of factors including portability, charging speeds, expandability, and overall value. After testing both models hands-on, we’ll provide key insights to help you determine which is the better choice for your needs and budget. Whether you need power while camping or during a blackout, this head-to-head review aims to demystify these complex but essential tools for energy resiliency. Let’s dive in!
Key Features
The Anker Powerhouse 767 has a few key features that differentiate it from the Ecoflow Delta Pro.
First, it utilizes Gan Prime technology which allows it to operate more efficiently than batteries without it. Gan Prime uses gallium nitride and Power IQ to enable faster charging, lighter weight, and cooler operation compared to traditional batteries. Since it runs cooler, the fans don’t need to turn on as often or as loudly.
In my testing, I could put a 600 watt load on the Anker without the fans turning on. In contrast, the Ecoflow fans turn on when loads exceed 60-70 watts. The Anker seems optimized to avoid fan noise as much as possible.
The Anker also has a unique built-in light which serves as a flashlight when you’re on camping or overlanding trips. It’s a handy secondary feature beyond the core purpose of portable power.
Overall, the Anker’s Gan Prime tech allows for faster charging, quieter operation, lighter weight, and handy bonus features like the built-in flashlight. These attributes make it a compelling offering in the portable power station market.
Portability
The Anker Powerhouse 767 is much easier to transport than the Ecoflow Delta Pro. The Ecoflow weighs around 100 lbs, which makes it extremely difficult for most people to lift and carry on their own. Even just wheeling it to your vehicle can be a challenge. In contrast, the Anker Powerhouse 767 weighs only 67 lbs. While still somewhat heavy, most adults should be able to briefly lift the Anker without injury. This makes it much easier to transport the Powerhouse 767 in your car or SUV for off-grid adventures.
The Ecoflow’s awkward, bulky shape also makes it difficult to maneuver, while the more compact Powerhouse 767 can fit nicely in most trunks. Overall, when it comes to portability and ease of transport, the Anker Powerhouse 767 is the clear winner over the much heavier and bulkier Ecoflow Delta Pro.
Anker Fans Quieter Than Ecoflow
One of the biggest advantages of the Anker Powerhouse 767 over the Ecoflow Delta Pro is that the fans are much quieter. I’ve found that the fans on the Ecoflow Delta Pro can become irritatingly loud, especially when powering over 60-70 watts. The fans will frequently turn on and drone loudly in the background. This has become so disruptive that I’ve stopped using my Ecoflow Delta Pro in my office because it interrupts phone calls and ruins video recordings.
The Anker Powerhouse 767, on the other hand, has much quieter fans. I’m able to power my entire studio setup, over 150 watts, without the fans turning on at all. Even when they do turn on, the Anker’s loudest fan setting is quieter than the Ecoflow’s quietest setting. This makes a big difference in keeping background noise to a minimum. I can power my studio equipment without constant fan buzz. Overall, the Anker Powerhouse’s quieter fans give it a clear advantage for powering electronics without adding distracting background noise.
Solar Charging
Another point for the Anker PowerHouse versus the Ecoflow Delta Pro is the solar charging capabilities. Ecoflow offers a 400W solar panel which requires building a large PVC frame to keep it pointed at the sun. This frame cost me around $80 in parts and time to construct. Even with the frame, the 400W panel is large and awkward – it likely won’t even fit in many small cars when folded up.
In contrast, Anker sent me a package with two of their 200W portable solar panels. These panels have built-in kickstands and leveling guides, making setup quick and easy. The kickstands can snap back into place with magnets for easy transport. Overall, the Anker solar panels are far more portable than the large 400W Ecoflow panel. Their compact size and intelligent design makes them ideal for off-grid adventures where portability is key. I can easily fit the two Anker panels in my car, whereas the Ecoflow 400W panel requires a permanent home in its PVC stand outside.
Capacity & Cost
The ecoflow Delta Pro has a capacity of 3.6 kilowatt hours and it can deliver up to 3.6 kilowatts of output but it also costs $3,600. That’s $1 per watt for both output and storage.
The Anker Powerhouse 767 has a capacity of 2 kilowatt hours and can power up to 2.4 kilowatts of stuff and only costs about $2,000. So a dollar per watt for storage but 20% more output for the dollar.
You can buy an additional battery for the PowerHouse giving you an additional 2 kilowatts for $1,000, which is 50 cents per watt hour – a really good value. The ecoflow Delta Pro’s extra battery is available for 75 cents per watt hour and costs $2,700.
What I’m seeing consistently across the board here is that the Anker products are a significantly better value for the dollar. With Anker you can reach a higher amount of storage capacity than ecoflow at a smaller price tag.
Maximum System Size
The Ecoflow Delta Pro and its ecosystem of products theoretically allow you to scale up to a much larger maximum capacity than the Anker Powerhouse 767, up to 25kWh. However, building out an Ecoflow system of that size gets extremely expensive very quickly.
To reach 25kWh of capacity with Ecoflow batteries and extra batteries costs over $22,000. In contrast, you could buy over 11 Anker Powerhouse 767 units for that price, totaling over 22kWh of capacity. While the Ecoflow ecosystem may allow seamless integration and control of a large battery capacity, the much lower cost of Anker’s offerings mean you can actually achieve a similar or greater capacity for a fraction of the price.
Unless you absolutely need a centralized large battery capacity and are willing to pay a premium for it, the Anker Powerhouse 767 provides outstanding value, delivering ample capacity and power at a reasonable cost. For most use cases, one or two Anker units more than suffice, making it hard to justify the 5-10x cost of a comparable Ecoflow system. The Anker Powerhouse 767 hits the sweet spot of high capacity, power and value.
Firmware Differences
The Ecoflow Delta Pro and their whole system has a more mature ecosystem of products and firmware that will operate with fewer compromises when you’re trying to go off-grid or during a blackout situation.
Specifically, the Ecoflow app allows you to enable or disable power output remotely via WiFi. This can be very convenient when integrating the batteries into a whole house system. For example, you could turn on the AC power to run appliances or sprinklers while you’re away from home.
The Anker Powerhouse does not currently have WiFi or app connectivity. Once the AC output turns off when the battery reaches 1%, it has to be manually turned back on. This makes integration into whole home systems more difficult.
Ideally the Anker Powerhouse firmware would be updated to automatically restart AC output once the battery charges back up to a certain percentage. This would greatly improve the daisy chaining capabilities and usefulness for automation. For now, the Ecoflow Delta Pro’s more mature firmware ecosystem provides more seamless operation for whole home integration.
Warranty
When investing in an expensive power tool for your outdoor adventures, the warranty is an important consideration. Anker offers an industry-leading 5-year warranty on the Powerhouse 767. This gives you peace of mind knowing the product will do what it’s supposed to for a reasonable amount of time.
In contrast, Ecoflow’s warranty is only 2 years. While Ecoflow is a reputable brand, Anker has proven itself over a longer period of time. Having been in business for many years, you can trust that Anker will stand behind their products.
The longer 5-year warranty on the Powerhouse 767 is a key advantage over the Ecoflow Delta Pro. You want confidence that an expensive investment like this will continue working properly for years to come. Since the Powerhouse is advertised as drop proof, the 5-year warranty further backs up Anker’s claims.
When choosing between the Ecoflow and Anker systems, the 50% longer warranty coverage provided by Anker makes the Powerhouse 767 the safer, more reliable choice for powering your adventures.
