LiFePo4 batteries with 1229 Wh, 230 V outputs with 1500 W, fast charging and UPS function – the solar generator Powerhouse 757 from Anker offers a successful overall package at a high price. TechStage has tested the mobile power storage for photovoltaics.

Power stations with an integrated solar generator and 230 V socket enable consumers to be supplied with power independently and far from the mains. Thanks to high performance and numerous connection options including 12 V connections and USB ports, the devices are ideal for hobbies, work or as an emergency power supply. The batteries are usually charged either with the power supply unit at the socket, with a 12 V vehicle connection or with the help of a solar module. The devices offer maximum flexibility and promise independence.

This power station test is part of our Outdoor and Camping theme worlds . Here we show, for example , high-tech gadgets for hiking , binoculars with a range finder or explain what to look out for when buying a flashlight .

This time it’s about the Portable Powerstation 757 from Anker . The manufacturer is a well-known supplier of electronic accessories, which has repeatedly impressed us with its decent price-performance ratio in the past. This test shows whether the strongest power station from Anker can convince.

The design of the black and silver anchor Powerhouse 757 differs significantly from the visual appearance of the smaller models Powerhouse 521 (test report) and Powerhouse 535 (test report) and we really like it. With dimensions of 463 mm x 288 mm x 237 mm and a weight of around 20 kg, the top model from Anker is still mobile, but the Powerhouse 757 is far too bulky for bike tours or hikes. The data speak for themselves: up to 1500 W output power (pure sine wave) per 230 V socket and a capacity of 1229 Wh.

The rectangular, rounded housing has two handles attached to the side of the upper edge. This makes transport easier and ensures a flat surface. This allows other items to be stacked on top of it, which we like.

However, the design is not entirely independent. How we got there is shown in the following photo, which shows the Powerhouse 757 in front of the solar generators Ecoflow Delta (test report) and Ecoflow River (test report) . Ultimately, Anker seems to have taken these two devices as a model. Whether it’s copied or happened by accident – we like the design and the workmanship is impeccable and of high quality.

Anker has placed all power outlets, buttons, lamp and status display on the front. Behind a small flap on the back are only the fuse, the power supply socket and the input for photovoltaics or the car power supply via XT60 plug.

On the front, at the top, there is an LED that runs across the entire width of the housing as emergency lighting. Their power button is placed on the right underneath. In the middle we find a small reset button, the power save switch, the large and bright status display and the display button. Below that on the left is the 12 V socket (cigarette lighter) with up to 120 W of power and its own power button, the total of six USB ports and the two 230 V sockets including the on/off button. What strikes us positively are the high-quality metal buttons for 12 V and 230 V outputs. It’s a shame that Anker doesn’t also use them for the lamp and display. It’s also a shame that Anker only put a protective cap on the 12 V connection. We would much prefer covered sockets for outdoor use.

The Powerhouse 757’s bright and large status display looks good and leaves a positive impression. In addition to the exact remaining capacity in 1 percent increments, the active outputs including the output power are shown here. The applied input power can also be seen at a glance. This helps, for example, when aligning the photovoltaic panel or panels. The remaining battery life or charging time and the power save mode are also visible. A practical extra that is only used on some models.

It’s positive that Anker uses a strong internal power supply with a full 1000 W for its flagship power station – similar to Ecoflow or Jackery, for example. Other manufacturers such as Bluetti only use external power supplies. These are bulky and often so weak that charging takes between five and eight hours. We also really like the high performance of the USB ports, which is also sufficient for energy-hungry consumers like our Macbook Pro. The four USB-A outputs each deliver 12 W, the two USB-C ports deliver 60 W and 100 W. You can confidently do without an additional power supply unit for a notebook, tablet or smartphone.

In addition to the Powerhouse 757 and power supply cable, instructions, a multiple XT60 adapter and a car plug are included in the scope of delivery.

Before starting the practical experience, we would like to briefly go into a special feature of the Powerhouse series from Anker: the power save function. The USB outputs of Anker power stations are always active, which leads to a slow but permanent discharge of the battery. If you don’t want that, activate the function. As a result, the Powerhouse recognizes when a USB device is connected and only then activates the corresponding output. In addition, the power station recognizes when a connected consumer such as an action cam, laptop or tablet is fully charged – the output is then switched off to save power. As a result, USB consumers can be plugged in and supplied at any time without having to switch the ports on and off again each time.

However, switching off the power saving function can make sense in some applications. We hooked up about a 360 camera overnight to capture a 12 hour time lapse. When the power save function is active, the power station would only supply the connected camera with power until its battery is full – but that would not be enough for a long recording time. Without the function, the camera is permanently supplied with power and so the recording works over a period of several days.

But now to the practical experience. First we charge the battery of the Powerhouse 757 at the socket. And thanks to the quick charge function, with just under 1000 W, this is really fast and still almost silent. The internal fan can hardly be heard even at the high summer room temperatures in the test. Only at the end of the charging phase does the fan turn up for about 15 minutes and is then also louder. However, most of the power stations tested so far make significantly more noise, often over the entire charging time. Charging from 0 to 100 percent takes around one hour and 33 minutes in the test, which corresponds to the manufacturer’s specification. We can also confirm that it goes from 0 to 80 percent in about an hour (62 minutes for us). Terrific! The power station can also be used at short notice!
