Brief conclusions of the comparison portable power stations

Comparing the EcoFlow DELTA 3 and DELTA 2 charging stations, it can be noted that both models have a nominal power of 1800 W and support a sinusoidal output. However, DELTA 3 offers a higher peak power of 3600 W compared to DELTA 2's 2700 W, making it more suitable for high-power devices. The charging time from the grid for DELTA 3 is about 60 minutes, while DELTA 2 requires about 80 minutes. Both stations have the same battery capacity of 20 Ah and use lithium iron phosphate batteries, but DELTA 3 has a longer lifespan with 4000 charging cycles versus 3000 for DELTA 2. In terms of outputs, DELTA 3 offers 2 USB A ports, while DELTA 2 has 4 USB A ports, including fast-charging ports. Users note that DELTA 3 is more convenient to use due to the placement of outputs in the front, whereas DELTA 2's are located at the back. Both models have similar dimensions and weight, but DELTA 3 is slightly heavier. Overall, DELTA 3 appears more advanced and powerful, while DELTA 2 might offer more charging ports.

Glossary

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.

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.

Add. ports

Additional input connectors provided in the design of the charging station in addition to those described above.

Charging cycles

The number of charge-discharge cycles that the battery can withstand without significant loss of performance.

In the process of operation, the batteries wear out, which causes their performance to suffer (in the first place, the capacity decreases). Battery life is usually measured in charge-discharge cycles. However, models with the same declared resource are not always equally durable in practice. Different manufacturers may interpret “significant loss of performance” in different ways: for example, one brand indicates the resource up to a 20% decrease in capacity (DOD > 80%), another - up to a 60% decrease (DOD > 40%) Behind the abbreviation DOD worth decoding Depth of Discharge, i.e. discharge depth. Therefore, when choosing, it makes sense to focus not only on pure numbers, but also on other sources - test results, reviews, etc. Also note that battery life can be noticeably reduced if the operating conditions are violated (for example, in case of overheating or hypothermia).

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 (solar panel) ≈

Time spent on a full charge when using the original panel in bright sunlight. In cloudy weather, the charging time of the device from the solar panel can be strikingly different downwards.

Charging power (socket)

The power at which, in normal mode, the portable power station is charged from a household outlet when using the original power supply.
