Brief conclusions of the comparison portable power stations

Comparing the BLUETTI PowerOak EB3A and EB55 charging stations, several key points can be highlighted. The EB3A has a rated power of 600W and a peak power of 1200W, while the EB55 offers higher ratings — 700W rated power and 1400W peak power. In terms of outputs, the EB3A is equipped with one 230V outlet and two 100-120V outlets, whereas the EB55 offers two 230V outlets, making it more versatile for connecting multiple devices. Both devices have 15W wireless charging and support solar panel charging. However, the EB55 has a larger battery capacity — 24Ah compared to 12Ah on the EB3A, providing longer operating time. Users note that the EB3A charges faster, but the EB55 is more powerful and suitable for more demanding devices. At the same time, the EB3A may be more convenient to carry due to its lighter weight (4.6 kg versus 7.5 kg for the EB55). Overall, the choice between these models depends on your needs: if you need more power and capacity, choose the EB55, while for lighter tasks, the EB3A will suffice.

Glossary

Rated power

Power that a device can consistently produce for an indefinitely long time without any unpleasant consequences. For normal operation of the charging station, the rated power must be at least 15 - 20% higher than the total power of all devices simultaneously connected to it.

Peak power

Some electrical appliances (in particular, units with electric motors - refrigerators, air conditioners, etc.) consume significantly more energy at startup than after reaching the operating mode. For such a load, the peak power of the charging station must be taken into account - its indicator must be higher than the starting power of the load.

UPS function

Charging stations with UPS function switch consumers to backup power from their own battery, acting as an uninterruptible power supply. In comparison with full-fledged UPSs, switching does not occur instantly, but with a certain delay (about 10-30 ms). To use this function correctly, you must first study the instructions for the charging station, which often describes the correct procedure for connecting the intended consumer devices.

Sockets (230 V)

Total number of outlets with output voltage. This is, in fact, the number of devices that can be simultaneously connected to the charging station without the use of splitters, extension cords and carriers. Accordingly, weaker charging stations have one or two sockets in their submission. Powerful charging stations already have three or more sockets “on board”.

USB A

Full-size USB A connectors are popular in computer technology, they are standardly used in adapter chargers for 230 V household networks and 12 V auto sockets. In charging stations, such outlets are widely used for charging gadgets.

- The total number of such ports can be very diverse ( 1 USB, 2 connectors, 3 ports and even 4), since it allows you to connect for charging, and in some cases for power, various low-power devices - smartphones, tablets, power banks, lamps, etc. .

- The strength of the power. The maximum power output through the USB A connector to the device being charged. Note that different ports of the charging station can output different power (for example, 1.5 A and 2.1 A). In this case, the highest power strength is usually indicated.

— Power. The maximum output power in watts (W) that the charging station is capable of delivering through the USB A connector to one charging device.

Input port XT60

Power connector with two round connectors, used to replenish energy reserves in the battery cells of the charging station. For the most part, the input port of the XT60 is for charging the device from solar panels using the appropriate cable.

Battery capacity

Nominal battery capacity, in fact - the amount of energy that is supposed to be stored. The larger it is, the longer the battery life of the charging station will be, all other things being equal. On the other hand, this parameter also affects the dimensions, weight and price of the battery, despite the fact that an energy-intensive battery is not always required. By the indicator of capacity in watt-hours, you can compare batteries with each other.

Charging time (socket) ≈

Time to charge the portable power station from a fully discharged state to 100% charge when using the power adapter from a household outlet. This refers to the original battery and standard charger.

Charging time (socket + solar panel) ≈

The parameter allows you to estimate the approximate battery charging time in the mode of combined connection of a portable power station - from a power outlet and a solar panel overnight. This method of replenishing energy reserves allows you to speed up the charging process.
