Brief conclusions of the comparison portable power stations

Comparing the BLUETTI AC70 and BLUETTI PowerOak EB55 charging stations, several key points can be highlighted. The AC70 has a rated power of 1000 W and a peak power of 2000 W, allowing for the connection of more powerful devices, while the EB55 offers 700 W rated and 1400 W peak power. Users note that the AC70 is more efficient for long-term power supply, such as a refrigerator, and has faster network charging (45 minutes to 80% versus 210 minutes for the EB55). However, the EB55 stands out for having more USB ports (4 USB A versus 2 for the AC70) and wireless charging, making it more versatile for charging mobile devices. In reviews, users praise both stations for their compactness and convenience, but the AC70 receives more positive reviews for its power and functionality, while the EB55 is valued for its price and sufficient power to work with laptops.

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.

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.

USB C

USB type C ports are smaller than classic USBs, and they also have a convenient reversible design that allows you to connect the plug in either direction. USB type C was originally designed to be able to implement various advanced features: increased power supply, fast charging technologies, etc.

Since the port is relatively new and quite powerful (there are USB type C with a power of 60 W and even 100 W), the total number of such connectors is often limited to 1 port, less often two).

- The strength of the power. The maximum power output through the USB type C connector to a charging device. 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 power in watts (W) that the charging station is capable of delivering to one rechargeable gadget. The high output power of the USB type C port allows you to speed up the charging process. However, the appropriate power must be supported by the device being charged - otherwise the speed of the process will be limited by the characteristics of the gadget.

Wireless charger

In wireless charging mode, energy is transferred to the gadget being charged through an inductive surface, which is usually built into the upper plane of the charging station case. There can be one slot for wireless charging or several of them are provided. The range of this technology does not exceed a few centimeters. However, this method of charging eliminates the fuss with wires and reduces wear on the connectors. One of the key disadvantages of this format is considered to be low power and, accordingly, slow charging speed.

DC output

The presence of a DC connector (or several such outputs) in the device to power external gadgets with direct current. The standard DC jack is round and has a pin in the center. However, its dimensions may differ in depth and diameter. The voltage output to the DC output may be different. The most popular options are 18 - 20 V for powering laptops, 12 V for various specialized devices and automotive electrical accessories.

DC input

DC connector for a distinctive round plug (like those used in many laptops) used to recharge the battery of the device. Note that DC- in plugs may have different sizes, and chargers with such plugs may have different operating voltages. In practice, this leads to the fact that finding a suitable charger for a portable station is not easy, you need to be especially careful when searching.

Connecting an additional battery

Ability to connect an external battery to the charging station to increase the overall energy consumption and, as a result, extend the battery life. This connection is fast and convenient. On the other hand, the battery takes up extra space on the outside, making the whole structure more cumbersome.
