As you can see, this is a relatively modern and compact power station. It’s designed to be useful not only during power outages but also for outdoor activities like camping or traveling.

Package contents

The Acer APS321 1800W arrived in a sturdy perforated cardboard box, equipped with plastic carry handles on both sides for easier transport. There’s no additional inner packaging for the power station itself.

Inside, the unit is secured with black foam polymer supports and wrapped in a polyethylene bag. On top, there’s a separate small box containing all the included accessories.

There aren’t many accessories included. You get three charging cables: one for AC wall outlets, one for solar panels, and one for a car socket. The package also contains printed user manuals and a warranty card. That’s all – but it’s enough to get the Acer power station up and running without any issues.

Design, materials, assembly, placement of elements

The power station follows a familiar design seen in many modern units: a compact rectangular shape with rounded corners. It has a clean, understated look. The body is made of dark gray, impact-resistant plastic, built to handle regular use. Overall build quality is solid and feels reliable.

It’s worth noting that the Acer APS321 1800W is relatively compact for its category, but quite heavy. With dimensions of 432×270×300 mm and a weight of 22 kg, you’ll feel it when carrying it around. This won’t be an issue in a home setting, whether in an apartment or a house. However, if you’re thinking of taking it on a hike into the mountains or forest, it’s probably not the best idea. It’s hard to imagine fitting it into a backpack or comfortably moving through the woods with it. This power station is better suited for transport by car to a campsite or outdoor base. Keep that in mind.

For easier transport, the unit features two built-in handles – cutouts located near the top toward the back panel. These cutouts also incorporate ventilation openings. Additional small vents can be found on the rear panel of the power station.

Placing the ventilation openings beneath the carry handles is a thoughtful design choice. Since warm air naturally rises, this layout helps the Acer APS321 1800W’s cooling system operate more efficiently by improving heat dissipation.

The fans are fairly loud and noticeable in quiet environments, but their noise is easily masked by something like a TV. In everyday use, they didn’t become a significant distraction.

On the rear panel, under a protective cover, you’ll find the ports used to charge the power station itself. Access requires opening this cover.

Inside, there’s an AC input port for charging from a standard outlet, a connector for solar panels, and a car cigarette lighter socket. There’s also a switch to toggle between fast and slow charging modes, located to the left of the ports.

The Acer APS321 1800W includes a practical feature that will appeal to travelers and others alike: an LED light located on the right side panel of the power station.

This means you don’t need to carry a separate lamp for lighting your campsite or tent. Just press a button to illuminate your space. It’s a practical feature that I found myself using frequently at home.

There’s also a dedicated button to turn the LED light on and cycle through its modes. You can choose from three brightness levels or an SOS flashing mode. On a lighter note, gamers might joke that it’s missing RGB lighting for a proper outdoor party vibe.

On this side, under the cover, there are additional output ports: one for a car cigarette lighter and two DC5521 power sockets. There’s also a switch to turn these ports on and off.

The left side is completely bare. It’s a bit unusual, as this space could have been used for ventilation openings or additional ports. That said, both sides do feature the Acer logo.

Most of the key features are located on the front panel. I’ll cover the LED display separately later. Below it, there’s a row of six USB ports: two USB-A ports rated at 5V/2.4A, one USB-A supporting fast charging at 5V/3A, 9V/2A, and 12V/1.5A (18W), and a USB-C port delivering 3.25A at 65W. It’s a respectable selection for a compact power station.

Below that, there are three 230V/4.3A AC outlets for powering household appliances. To the left, you’ll find a switch to turn these outlets on and off.

The 230V outlets and USB ports are fully exposed and don’t have rubber covers. Because of this, it’s important to be careful during use to avoid foreign objects getting inside, especially when using the station outdoors.

On the bottom, there are two rubberized feet that help keep the unit stable on a table or floor. The center area features all the relevant device information.

Display and control

At the center of the front panel, near the top, the Acer APS321 1800W features an informative LED display.

To the right of the display is the power button for the station, while on the left, there’s a button to turn the display on and off.

One subjective observation: although you can turn off the LED screen with a quick button press, the display automatically lights up again every time the station switches between operating modes.

The display itself is clear and bright, with no issues. It shows key information such as input and output power for all ports, battery charge level, and estimated remaining runtime. It’s worth noting that the power station doesn’t have a built-in settings menu. Additionally, some users may be disappointed by the lack of smartphone control, as there is no mobile app available for managing the unit remotely.

There’s no way to actively control or customize the power station – no settings to adjust. You simply press the main power button and then the switch for the AC outlets to start using it. The USB ports remain powered on as long as the station is running.

In other words, the station uses simple mechanical button controls. On one hand, this is straightforward and practical. On the other, most modern devices now offer mobile app control. Perhaps Acer will develop an app for this model in the future.

Experience of using Acer APS321 1800W

Now let’s move on to the most important part of any review – real-world use.

I was curious about everything. Would my household appliances work during a power outage? Could the station handle all of them? How does it perform as an uninterruptible power supply (UPS)? And is it convenient to use while traveling? The 1229 Wh battery capacity looked promising and gave me some confidence going in.

I knew this was a fairly powerful power station, capable of running household devices. Still, the actual tests were unexpectedly reassuring. I was fortunate – there were no power outages in my hometown of Kharkiv during the review period – but I still wanted to see how the device performed under real-world conditions. I connected several devices to the Acer APS321 1800W at once: a 55-inch KIVI TV, an ASUS monitor, a Wi-Fi 6 router, four laptops, two smartphones, and an LED light. The station handled the load without issue.

But I wanted to push it further. I connected a double-door refrigerator, which averages around 150W of power consumption. The Acer APS321 1800W ran it for over 5.5 hours on a single charge, which is a respectable result. During that time, I also used a microwave and ground coffee with an electric grinder. The station handled everything without any power issues. I even attempted to connect a water heater, but that didn’t go as planned – the built-in protection kicked in and shut off the inverter. Based on this, it’s clear that the station can handle most medium-power household appliances. In the event of a blackout, it should be enough to keep your lights and Internet running, charge laptops and phones, and keep your food from spoiling.

In addition to passthrough charging – something available on many power stations – Acer’s new model also includes a built-in UPS (uninterruptible power supply). This means there’s no need to power down the station at all during regular use. There’s no specific UPS indicator on the LCD screen, likely because the function operates automatically and can’t be toggled on or off manually.

The UPS mode on the Acer APS321 is fairly decent. On paper, its switchover time is ≤14ms – which is slower than a professional-grade UPS (typically rated at ≤5ms), but still acceptable for most home setups. I kept a monitor and a Wi-Fi router constantly connected to the station. During switchover from grid power to battery, there were no screen flickers or Wi-Fi dropouts. In fact, I often didn’t even notice when the main power was cut.

I also had the chance to test Acer’s new power station during a trip outside the city. It performed reliably across the board – everything worked, everything charged without issue. We even ran an LED lamp, and it handled it smoothly. For travelers, this kind of device is genuinely practical. If you’re looking to use it for gaming, the station can handle that too. I connected a 55-inch Full HD TV and an Xbox Series S, which together drew around 70–100W, with occasional spikes up to 130–150W. That setup is good for at least 2–3 hours of gaming, possibly more.

I also tested it with a gaming laptop and a 32-inch 2K monitor while playing S.T.A.L.K.E.R. 2 – a more demanding setup. Power usage averaged 150–170W, meaning the station can keep that running for about 1–2 hours.

Based on my testing experience, I can confirm that Acer’s power station is well-suited for basic gadget charging – smartphones, smartwatches, laptops, power banks, headphones, and similar devices. It’s also capable of powering household appliances. Naturally, not all of them and not always at full capacity, but it handles a reasonable range of everyday devices without issue.

Charging process

It’s definitely best to charge the station from a wall outlet using the standard mode. The AC fast-charging feature is genuinely useful – it significantly cuts down the time needed to recharge the internal battery. In my tests, a full charge took around two hours, which matches the manufacturer’s claims.

The power station can also be charged using solar panels, a car cigarette lighter, or an external battery. Unfortunately, I don’t have solar panels to test that method, so I can’t comment on it. However, I did try charging via the car cigarette lighter. The process is significantly slower than charging from a wall outlet, but it can be useful in certain situations.

A few words about the noise level of the Acer power station. The fan kicks in almost immediately under load, but the noise isn’t excessive. It was easily masked by the sound of a TV. You’ll also hear the fan running while the unit is charging. The noise level during intensive operation reminded me of my old PC’s fan. According to the official specs, the noise level ranges from 40 to 45 dB, which matches my experience.

Conclusions

I can confidently say that Acer’s entry into the power station market is a solid one. The Acer APS321 1800W is both compact and powerful enough for home use, capable of supporting most household appliances as well as charging laptops, smartphones, and similar devices.

Of course, the unit isn’t without its drawbacks. The main issue is the lack of remote control options, as there is no mobile app available – something Acer should consider addressing. Additionally, the absence of rubber covers on the AC outlets and USB ports stood out to me, especially since dust and dirt are likely to get inside during travel or outdoor use.

The unit I tested is a modern power station featuring fast charging and a built-in UPS with a switchover time of 14 ms. This makes it a valuable tool during power outages. Additionally, the Acer APS321 1800W delivers a continuous power output of up to 1800W, with a peak capacity of 3000W, and a rated lifespan of up to 3000 charge cycles. Honestly, I wouldn’t hesitate to keep this power station for personal use.

If you’re looking for a compact and powerful power station for home use and travel, the Acer APS321 1800W is a solid option. It offers good value for the price.
