Anker launched the new Anker 555 PowerHouse a few months ago in the US. This is now coming to the UK and EU with an early bird offer. In the UK, you can apply for a coupon code which will take £240 off the price knocking it down to £859. You can apply now, but the sale starts on the 10th of October.

This is a 1024Wh portable power station using LifePO4 batteries, which I think is the sweet spot for a lot of buyers that want something that can handle demanding scenarios without getting overly expensive.

This new power station fills the gap between the 512Wh Anker 535 and the recently launched flagship Anker 757 PowerHouse, which costs £1400.

It goes up against the recently launched and superb EcoFlow Delta 2 and the Jackery Explorer 1000. US buyers have the option for the new $1099 Jackery Explorer 1000 Pro, which is closer in specification to the Delta 2 and 555 PowerHouse.

Anker 555 PowerHouse Key Differences


Price Difference

Ignoring the early bird discount, this is priced the same as the EcoFlow DELTA  2 and slightly under the RRP of the Jackery Explorer 1000. For US buyers, it is the same price or $100 cheaper than the Jackery Explorer 1000 Pro.

Battery Technology

This uses a LiFePO4 battery with a claimed 3000 cycles before you hit 80%, which matches the Delta 2 and is better than Jackery. Both Anker and EcoFlow also offer a 5-year warranty, you have to register the EcoFlow to get this.

I should point out that while the Jackery looks less impressive with its 500 cycles to 80%+ capacity, the reality is that unless you are a heavy daily user, I can’t imagine making it a massive difference. One full charge per week is almost 10 years, and you’d still have 80%+ capacity.

AC Output & USB Ouput

The AC output is lower than competing brands, it is 1000W max with a surge of 1500W, and you only get two sockets. The Delta 2 has 4 sockets and 1800W with 2400W with the X-Bost and 2700W surge. Jackery has 3 sockets which can do 1000W max and 2000W surge.

Mains Charging

For some reason, Anker has made this quite slow for charging with just 120W. It seems to be due to the mains charger requiring a power brick vs a built-in AC charger. The Anker 757 does 1000W AC charging, the Delta 2 is even more impressive at 1200W. I even saw the Jackery Explorer do more than 120W. This means an 80% charge will take about 4 hours vs 60 minutes on the EcoFlow.  

I recently wondered why no power station has USB power delivery input for a slow but convenient charging method. Well, the Anker 555 PowerHouse has this, with a limit of 100W. Considering the size of the power brick, I could imagine that I would use 100W power delivery quite a lot with this (for overnight charging, at least).

Solar Charging

Solar input is 200W, which matches the Jackery but is behind the 500W of the Delta 2 and well behind the 4x200W SolarSaga that the Jackery Explorer 1000 Pro can handle.

The EcoFlow 400W solar panel costs £999 so higher capacity solar charging is an expensive investment.

Size & Dimensions

The Anker 555 PowerHouse weighs in at 13.1kg, which is significantly lighter than the nearly 20kg 757 PowerHouse. However, it is still heavier than the 12KG Delta 2 or the 10KG Explorer 1000.

However, the overall dimensions of 350 x 295 x 188 mm make it smaller than both the EcoFlow and Jackery.

The Anker 555 has some big downsides vs the EcoFlow Delta 2. The AC output is not as good, and the charging is slower. It also has less capacity for solar charging, but 200W is still plenty, especially when you look at the prices of solar panels. I quite like the idea of the 100W USB-C charging, it is not very fast, but adequate for overnight.

With the early bird offer, you are saving £240 vs the Delta 2, which I think is more than enough to justify its small shortcomings.

  1. Hi,
    Do you know if the solar connection is proprietary or if any solar input of the correct wattage can be used?


    1. I finally got confirmation.

      They work by connecting the male and female XT-60 ports. And then, plugging the male DC7909 port into the PPS. And the solar input specification of 555 is 120W Max and 10 amps Max.

  2. Hi
    I’ve seen some video reviews of the Eco series that seem pretty loud in use,

    Wondered if you’d done any comparisons regarding noise level compared to the Anker 555 / 757, or at least some casual experiences of day to day use and fan noise?

    I’m moving to a regular towable caravan from a house, and so any power unit I get will be relatively close by.


    1. Good point. Charging the Delta 2 can get noisy at higher wattages. Not 100% sure about in use as I am rarely sat in the same room as it, but I have another Jackery on the way and will test both that and the DELTA 2 in my office and update my reviews.
