Meanwhile, newcomer Oscal is trying to go the other way with the PowerMax 2400 Pro \u2013 offering a lot of power and a modular approach, deliberately giving up some of the \u201epremium\u201c sophistication, but in return offering a much more attractive price. So what is this model and can Oscal\u2019s attempt to establish itself in this market be considered successful?<\/p>\n

<\/p>\nUnpacking<\/h2>\n
The PowerMax 2400 Pro comes in a heavy and massive box \u2013 but this is exactly the case when the weight is not surprising, but reassuring. After all, a mobile power station of this caliber should not be light. Inside, the device is packaged thoughtfully and safely, and I share the unpacking experience in video format.<\/p>\n
Assembly quality<\/h2>\n
Upon closer inspection of the PowerMax 2400 Pro, the first impression remains quite positive. The design is modern, with accent colors, visually neat and at first glance may remind you of a mobile speaker - especially because of the grilles on the sides, imitating speakers. This gives a certain uniqueness and allows the station to not look like an ordinary technical device that you would like to hide from view.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-6.jpg\" "\\"Oscal")
<\/p>\nHowever, after a longer period of testing and use, it becomes clear where the price compromises lie. The plastic used in the housing is simpler than, for example, the previously tested Bluetti Elite 200 V2, and the overall assembly feeling is not as solid. Nothing rattles, does not seem loose or insecurely attached, but the "premium" feeling is clearly less here.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-4.jpg\" "\\"Oscal")
<\/p>\nThe instructions are in English and, although visually clear and supported by graphic diagrams, they do not answer all practical questions. For example, why does the sound come from only one side, although the \u201espeakers\u201c are visually visible on both? The answer is simple \u2013 the speaker is only on one side, and the other is for cooling. It is simply a design decision that imitates symmetry.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-23.jpg\" "\\"Oscal")
<\/p>\nOn the bright side, if the cheaper plastic can withstand the knocks and daily use of the Bluetti alternative over time, the money saved may be worth investing elsewhere. The PowerMax 2400 Pro is modular, meaning you can add up to ten additional batteries to it, increasing the capacity from the base 2016 Wh to as much as 22,176 Wh. The process of attaching and removing modules is simple, convenient, and straightforward.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-24.jpg\" "\\"Oscal")
<\/p>\nPower and practical use tests<\/h2>\n
The PowerMax 2400 Pro has a base capacity of 2016 Wh and a nominal output power of 2400 W, with the ability to briefly increase to 4800 W. This means that the station should be able to handle not only small electronics, but also more energy-intensive household appliances or power tools without any problems. But is this realistic?<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-19.jpg\" "\\"Oscal")
<\/p>\nAs long as the total load does not exceed 2400 W, Oscal behaves as expected - stably and reliably. A vacuum cleaner, an electric saw, a kettle, or charging multiple devices at the same time did not cause any problems.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-22.jpg\" "\\"Oscal")
<\/p>\nHowever, if you try to exceed this limit, for example by connecting a 2000 W heater together with a 1000 W vacuum cleaner, the PowerMax switches off after a few seconds. So, the protections are triggered as they should be.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-15.jpg\" "\\"Oscal")
<\/p>\nI was pleasantly surprised by the number of ports. Unlike the Bluetti Elite 200 v2, there is no shortage of them here: 4 AC outlets, 4 \u00d7 USB-A, 2 \u00d7 USB-C, 2 \u00d7 DC5521, as well as one car cigarette lighter and Anderson connector. It's great that you don't have to look for compromises or extension cords.<\/p>\n

<\/p>\nUPS function<\/h2>\n
In the event of a power outage, the PowerMax 2400 Pro also has a UPS function, with a claimed switchover time of just 0.01 s. In practice, this is difficult to verify, as the switchover occurs so quickly that the connected devices simply do not have time to react.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-30.jpg\" "\\"Oscal")
<\/p>\nDuring testing, a power outage had no effect on the TV, phone charging, or even briefly connected more powerful devices, such as a teapot or electric saw. For domestic use, this UPS function works reliably.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-31.jpg\" "\\"Oscal")
<\/p>\nCharging<\/h2>\n
The charging speed doesn't disappoint either. Using alternating current (AC) charging, the PowerMax charges at around 1400W (adjustable in the app from 100W to 1400W), and a full charge takes around 1.5 hours. In comparison, the Bluetti Elite 200 V2 is slightly ahead here with 1800W charging.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-29.jpg\" "\\"Oscal")
<\/p>\nHowever, it should be noted that the cooling is quite loud when it is turned on during charging, so being near the station at that time is not the most pleasant thing. In addition to AC charging, the PowerMax also supports solar charging. Both charging types can be used simultaneously.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-27.jpg\" "\\"Oscal")
<\/p>\nAs expected in this segment, LiFePO\u2084 batteries are used. They are durable and retain a large part of their original capacity even after several thousand charging cycles.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-25.jpg\" "\\"Oscal")
<\/p>\nApp<\/h2>\n
Oddly enough, Oscal does not have its own separate app and uses the common Smart Life platform. In it, the PowerMax 2400 Pro control is quite elementary - you can turn on individual modules (AC, USB, etc.), monitor charging and discharging information, and update the software. There are no superfluous functions here, but it is enough for basic control.<\/p>\n

<\/p>\nAdditional features<\/h2>\n
The station also has several additional features. One of them is an LED strip for lighting. It is not the most powerful spotlight, but it is perfect for background lighting, for example, in a tent. There are also 2 places for wireless charging on top. Both of them are 15 W - although the speed is not record-breaking, it is an additional charging option with endless connections.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-10.jpg\" "\\"Oscal")
<\/p>\nThe Oscal-accented speaker didn't leave much of an impression. Yes, it's useful in situations where nothing else is at hand, but the sound quality is quite poor - lacking bass and overall clarity.<\/p>\n
![\"\"](\"https:\/\/niuxtech.lt\/wp-content\/uploads\/2022\/12\/Oscal-PowerMax-2400-Pro-28.jpg\" "\\"Oscal")
<\/p>\nVerdict<\/h2>\n
Oscal PowerMax 2400 Pro is a rational choice for users who value power, modular flexibility and an attractive price. Although the control feel and some details are not as refined as in the "premium" segment, the overall functionality and expansion options allow this mobile power station to be considered a serious competitor to more established manufacturers. \u200b<\/p>\n
