Power in a suitcase - Tallpower V2400 Power Station test

The Tallpower V2400 is a real powerhouse with its 2160 Wh capacity and up to 2400 watts of continuous AC output. You can count on this package even if everything else has turned out to be insufficient.

Average, affordable home power plants have a maximum output somewhere between 800 and 1200 watts. It is usually enough to operate smaller two-twenty machines, charge several mobile devices at the same time, and the like. However, this performance will no longer be enough for a serious hand tool or, if we are very cold, for a heat radiator.

A Tallpower V2400 it is not cheap either, but we can say that it is one of the cheapest packages available on the market with similar performance. There was no question, we had to test it when we got the chance these mobile charging stations are a clean and quiet alternative to traditional gasoline-powered generators. We skinned the poor guy properly, but the Tallpower V2400 was a mess. We were impressed with its built-in inverter, charge controller, BMS battery protection and multiple charger outputs.

The Tallpower V2400 came packaged in two strong cardboard boxes. The upper part of the energy cube, hidden in the sponge bed and closed with a lid, contains various accessories. These include the AC charging cable with built-in adapter, The Solar charging cable equipped with MC4 and XT90 connectors, cigarette lighter charger, as well as the user guide.

It is important to note that the V2400 is not a compact powerhouse suitable for long-distance transportation. It is not only quite large, From its dimensions of 390 × 285 × 320 mm, but also of its weight of 20,5 kg also stands out. As a result, this model is best suited for recreational vehicles, camping, or as a stationary power source or energy storage solution.

However, despite its hefty weight, the V2400 can be easily transported over short distances thanks to its practical design and the convenient carrying handles located on the right and upper left of the power plant. The V2400 offers a convenient storage solution for cables in a closed compartment in the upper part of the power plant. In addition, this model has a timeless design reminiscent of other manufacturers.

Despite the affordable price of the mobile energy storage, it boasts an excellent design despite the use of cost-effective materials. To turn the power plant on or off, simply use the main switch located in the upper right corner of the front panel. Directly below is the silver one charge power control button, which allows you to adjust the charging power to protect the battery cells. We can choose between 1100 watts, 900, 700, 500 and 300 watts. The thanks to a total of 13 outputs we can easily connect various devices.

Let's examine these options in turn. You can activate the USB, DC and AC ports by pressing a separate button. 4 USB-C ports located (3 PD20W, 1 PD100W) and 2 USB-A ports (QC3.0 18W). On the left side are the DC outputs, which are sealed with a rubber plug. These include the 2 DC 5521's socket (12V/3A), a cigarette lighter socket (12V/10A) and one XT60 socket (12V/25A), which are usually used to charge drones. Also, there is one LED lamp, which emits a pleasant warm light, as well as in an emergency SOS light signal can also be used for delivery.

Unfortunately, there is no phone application available for the V2400 power plant. However, the front panel decorated with LCD display provides a great visual experience by connecting us with every detail about the current status. The display shows the currently used outputs, the input and output power, the estimated remaining operating time or charging time, and the current battery charge level. In addition, the symbols on the display serve as indicators of possible problems, such as overheating or overloading.

To access the V2400's charging ports, you need to lift the plastic cover on the left side of the power plant, just below the overload protection button. There are many charging options available. Of course, the most advantageous method is charging through the MPPT input with the help of a solar panel. The XT90 connector enables connection of 11,5-50V/20A, maximum 500 watt solar panel. We installed a 415-watt panel on the south-facing roof, tilted at an angle of 37 degrees. The isolated system is equipped with lightning and surge protection and a 32A DC disconnect switch.

Another charging option is the supplied cigarette lighter charger, so there is practically zero loss (DC-DC), but it takes a long time to charge. The machine can be charged with the attached a using a mains charging cable from a wall socket, which has a power of up to 1100 watts can also provide, or a by combining a solar panel and mains charging. With this combination, the unit can be charged to 1600% in 1,5 hours with 100 watts.

On the right side (also under the cover) we find the three traditional, pure sine wave EU standard outlet, which It delivers 230 V at 50 Hz, but it can be manually switched to 2 Hz by pressing the AC button for 60 seconds, although this is not allowed in Hungary. The power station on the alternating current outlets Capable of delivering 2400 W nominal (continuous) and 4800 W (momentary) peak power. There are two fans on each side of the machine body, ensuring quiet operation At a measured volume of 30-40 dB, under pressure.

Our test subject uses lithium iron phosphate (LiFePO4) battery cells, which are known for their durability compared to lithium-ion technology. This is also proven by the battery life, since It reaches 3500% of its nominal capacity even after 80 charging cycles.

If you continuously charge the battery to maximum capacity and drain it completely, this battery will last a solid decade. THE The manufacturer even offers a generous 5-year warranty for customer satisfaction.

One of the main advantages of this technology is resistance to physical damage, so it is extremely reliable. Furthermore these batteries also comply with the strictest safety standards, thus providing protection against potential fire and explosion hazards. The portable charging station is equipped with a sophisticated battery management system (BMS) that continuously monitors voltage, current and temperature from multiple angles to protect the battery. BMS effectively protects the battery from short circuit, over current, high or low voltage, over charging and overheating. We also continuously monitored the temperatures with a thermal camera. 

This is the mobile energy storage unit it can also function as an uninterruptible power supply (UPS)., which serves as an emergency power source. In the event of a power outage, the power plant seamlessly switches to an emergency power generator, so that's all Within 8 ms the energy storage device acts as a power supplier. This is especially important for electronic devices that need to work continuously. One of the best examples that comes to mind is the refrigerator, or rather the servers and the applications and services running on them, which can thus function without stopping. 

A Tallpower V2400 egy 48V/15Ah battery pack containing 3,2 volt 33140 cells, altogether It provides 2160 watt hours. However, it is important to note that this capacity only applies to the battery cells themselves. Due to operational losses and voltage conversion, the actual energy reaching the end devices is reduced. In order to accurately measure the real capacity, we connected household appliances to the V2400 socket.

We started the complete discharge of the battery with a semi-professional coffee machine, which its peak current consumption is 1258 watts volt.

After that, we ran two 30-minute washing cycles with a washing machine, With a maximum current consumption of 2067 watts.

By this time we were very hungry, so we made it using the free electricity from the power station Master Jenő's fur bread a For Joyami double basket hot air oven, which It required 2428 watts of energy at peak.

It also needed some washing up, so one intelligent desktop dishwasher used for further testing of the device, drawing it to 63% capacity.

Then we loaded it with a compressor, here The continuous load was 800 watts. Then came another round with the hot air oven, then another 30 minutes with the washing machine, followed by a little blow-drying.

Sucking out the remaining 5% to the Terminator of Dust Mites - which, by the way, is a mandatory product for allergy sufferers, recommended for everyone else - we trusted.

The immersion operation that is battery discharge from 100% to 0% reported, total It lasted 3 hours and 31 minutes. During the process We were able to measure a usable capacity of 17033 Wh. Although this seems small compared to the rated capacity of 2160 watt hours, it is actually quite satisfactory. Manufacturers typically leave a minimum of 200 watt-hours in LiFePO4 batteries to prevent deep discharge, so we can use the remaining 1960 watt-hours. The measured power of 17033 Wh a corresponds to 81% of factory capacity, which is considered an average value.

The efficiency of the pure sine wave inverter is also commendable, despite the fact that losses occur during the conversion of alternating current to direct current. The power plant To fully charge it from 0% to 100%, we pulled 2243 Wh from the wall socket with the supplied power cable. This is atstitching process took 2 hours 31 minutes. So the charge loss compared to the factory capacity of 2160 Wh It accounted for 83 Wh.

Needless to say, many other things can be operated from the Tallpower V2400, not only the devices we have presented.

Unfortunately, our USB multimeter hasn't arrived yet, and we can't measure the output capacity on the DC branch either, so we can't check the actual performance of these outputs. However the 12 V and its usable capacity, which can be removed from the USB ports, is always greater than at 230 V, because the conversion losses are much smaller. The charging station drains more slowly if the laptop is running via Type C PD output (not AC output). Experience shows that most losses occur when using low-power 230 V consumers.

• Tip: Do not use USB devices with the corresponding network adapter, but operate/charge them directly on the USB port without an adapter - so the inverter in the charging station does not have to work, this saves energy, and the energy cube will have a longer operating time.
• If the AC switch is on and there is no consumption, the charging station will automatically switch off after 8 hours!

A Tallpower V2400stood out from its competitors with its lithium-iron-phosphate battery and exceptional price-performance ratio. Currently, no manufacturer offers a portable power station that offers 2160 Wh battery capacity and 2400 watts of continuous power via a pure sine wave inverter under $900. In addition, the V2400 excels in areas such as low noise, protected ports, fast charging, emergency power supply function thanks to UPS and charging power control button.

However, it's worth noting that the capacity can't be expanded with an additional battery, and a wireless charging pad or a phone app for remote control would be a valuable addition. Furthermore, it would be more practical if the three 230 V sockets were located at the front of the unit.
