The poweroak AC50S is a compact solar generator with an integrated battery with a capacity of 500 Wh and two 230 V sockets with an output of 300 W. We tested the mobile solar power plant in practice.

Power stations with solar generators enable the use of electrical devices far away from the power grid. In combination with a solar panel, the devices promise a self-sufficient and mobile power supply using only the sun and are therefore ideal for emergency power supply or for hobbies and camping.

This test is part of the 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 .

In this individual test, the editors took on the power station Poweroak AC50S from the manufacturer bluetti, which was made available to us by Banggood, where the model is listed together with the 120 W panel for 1041 euros.

This solar generator is the smaller successor version of the Bluetti Poweroak EB70 (test report) tested in March, or the smallest sister model of the huge XL power station Poweroak AC200 Max (test report). In addition to a decent capacity and a chic design, the device attracts with good features such as a wireless charging pad.

With dimensions of 26 x 19 x 20 cm, the Poweroak AC50S is slightly smaller and at 6.2 kg also almost 4 kg lighter than the Poweroak EB70 (test report) , with which we started our solar generators theme world at the time. This is partly due to the lower capacity of 500 Wh. The EB70 also uses a modern and more durable, but also heavier LiFePo4 battery.

The two-tone plastic case is well made and leaves a high-quality impression. Rubberized feet ensure a stable stand. While the side parts with the ventilation slots and the actual control and connection panel are dark gray, the rest of the power station shines in a bright sky blue. These housing parts are also rubberized and thus additionally protected.

The blue parts are soft rubberized. 

The AC50S has a two-part folding handle on the top for easy transport. Terrific! The device is as compact as possible and can be stacked. A wireless charging area is also integrated on the top. Appropriately equipped smartphones or headphones can be charged with up to 10 W.

The power input and the emergency lamp with power button are located on the back. All other connections, function keys and the colored status display are on the front. On the top left are the on/off button and the buttons for activating the DC and AC outputs. Next to it are the display and the three 12 V outputs (2x 12 V 3 A round plugs, 1x 12 V cigarette lighter 10 A).

A total of five USB ports are located at the bottom left. In addition to four times 5 V with 3 A, a USB-C PD port with 45 W is also available. Smaller notebooks, tablets and other gadgets can usually be charged without an additional power supply. Very pleasant. The two 230 V connections, each with 300 W pure sine wave, are placed on the bottom right. It’s a shame that Bluetti only gave the cigarette lighter a protective cap on the small AC50S. The remaining cans are unprotected and therefore susceptible to dirt. We would wish for something different, especially for outdoor use. Unfortunately, this point of criticism applies to practically all devices tested so far – with the exception of the large Poweroak AC200 Max.

Unlike Ecoflow or Jackery, for example, Bluetti unfortunately uses an external power supply again for the AC50S. This is not as big a chunk as the AC200 Max, for example, but the additional device still needs space. In addition to instructions, power station and power supply unit, a solar plug to 8 mm adapter, a charging cable for the cigarette lighter and a USB-C to USB-C cable are also included.

A solar module is not included. The Bluetti Poweroak SP120 with 120 W was made available to us for the test. Alternatively, the panels from Jackery or Ecoflow also work without any additional accessories. The inexpensive panels from Xmund or Flashfish, for example, also worked with the appropriate adapters. Solar modules with 12 to 40 V are compatible. The maximum usable power is 120 W.

The operation of the power station is self-explanatory thanks to the proper labeling and works without any problems. If you want to know how many watts are currently being charged or output, briefly press one of the buttons on the lamp, 230 V sockets or DC outputs. The display then shows the current status of the power station for around 20 seconds. If you want to switch the LED or the outputs for direct and alternating current on and off, you have to press and hold the respective switch for about 2 seconds. A small LED in the respective power button and an indicator on the display show whether the outputs are active.

Simultaneous charging and discharging of the power station is possible, but the manufacturer advises against it in order to ensure a longer battery life. As a reminder, the manufacturer states that Li-Ion batteries still have around 80 percent residual capacity after 1000 charging cycles. With the LiFePo4 batteries of the Poweroak EB70 (test report) between 2500 and 3500 charging cycles are possible.

First we charge the Poweroak AC50S with the power pack. The charging process takes almost exactly 4.5 hours from 0 to 100 percent. After plugging in, the display starts immediately and shows the incoming charging power of 75 W. Unlike the EB70, both the fans of the power supply and those of the power station remain silent while charging at the socket – at least most of the time. Towards the end of the charging process, the fan starts up audibly – but only for a few minutes. Very pleasant, as this was one of the biggest criticisms of the Poweroak EB70.

Now we start with the first load tests. First, we plug in our home-made arcade machine (guide) with a 27-inch monitor, retro emulator, lighting and speakers. Even while gaming, this combination draws a maximum of 60 W, which doesn’t even come close to challenging the specified 300 W. So we connect various tools, our 50-inch TV (LED) and various kitchen appliances. While TVs, drills, hot glue guns and jigsaws work without any problems, the power station quickly reaches its limits with table saws, toasters, deep fryers and induction hotplates with 900 to 3000 W. The automatic shutdown in case of overload works reliably.

Brief peaks of up to 450 W are possible, but the power station cannot withstand this for more than a few seconds. Consumers such as laptops, chargers for RC toys, cameras and drones are no problem for the Poweroak AC50S. How long the various devices can be supplied depends on the respective consumption. 12 V connections, USB ports and wireless charging function also worked well in the test. At a high output power of more than 100 W, the power station’s fan switches on again – but not permanently and quieter than with the Poweroak EB150 (test report) or EB70 (test report) .

In the tests, we draw between 421 and 442 Wh from the fully charged power station – this corresponds to a loss of 12 to 16 percent with regard to the specified 500 Wh. A conversion loss of 15 percent is standard. The values ​​​​achieved in the various runs are therefore a decent value. The power station supplies our home office with Macbook Pro, several monitors, telephone and printer for almost four and a half hours at a time.

We are also testing photovoltaic charging. The 120 W panel from Bluetti delivers between 65 W and 100 W on the day of the test, so it takes just over six and a half hours for the power station to be fully charged by solar power. With a better placement and a higher yield, the battery should be full in just under 4.5 hours. The fan remains silent most of the time during charging despite the high outside temperature.

The Poweroak AC50S is available in Orange-Black and Blue-Black. Powerstation is available from German dealers from 499 euros, which we think is reasonable. The bundle together with the solar panel SP120 (120 W) is available from 899 euros. The panel alone is listed from 339 euros in the price comparison. The bundle is currently listed at Banggood for 1050 euros . We hope that there will be a discount code for a reasonable price here soon.

The Bluetti Poweroak AC50S is a compact and reliable power station with many connection options. We like the combination of robust construction and mostly silent operation. If you don’t want to do without an ice cube machine and fan the next time you visit a quarry pond, campsite or model airfield, the AC50S is a small and sufficiently enduring power storage device for on the go.

It’s just a pity that Bluetti uses an external power supply again and also does without covers for the connections. The use of Li-Ion batteries enables a particularly compact design, but we would still prefer the significantly longer-lasting LiFePo4s of the Poweroak EB70. If you want significantly more power and a bit more capacity, you should take a look at the Bluetti Poweroak EB70 (test report) .

The models XD-PS10 from Xmund (test report) with 500 W and 500 Wh for 578 euros, the Flashfish UA550 (test report) with 600 W and 550 Wh for 600 euros or the Anker Powerhouse 535 (test report) also play in a similar performance class 500 W and 523 Wh for 700 euros.
