Comparison EcoPlay EP2400 vs Oukitel P2001

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.

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.

The delay (usually in milliseconds) between the power going out from the outlet and the moment when the station starts feeding connected devices from its battery, maintaining "pass-through" power. The shorter this time, the higher the chance that devices won't notice the drop at all: for routers, cameras, NAS, and PCs, this is critical because a long pause can cause a reboot, loss of connection, or even filesystem errors. Essentially, this is the same parameter as in a classic UPS, but for charging stations, it greatly depends on implementation: models with a more "UPS-like" switching scheme switch considerably faster, while some stations formally have a UPS mode but actually create a noticeable break or activate the output only after "realizing" the network's loss. In practice, this point helps distinguish a charging station that is truly suitable as a UPS for sensitive electronics from an option "for lights and charging": for example, for home internet and video surveillance, minimal switching time is important, while for lamps, charging phones, or a heater, a brief pause is typically not critical.

Full-size USB-A connectors are popular in computer technology, commonly used in charging adapters for 230 V household networks and 12 V car sockets. These outputs have become widespread in charging stations for charging gadgets.

— The total number of such ports can be quite varied (1 USB, 2 connectors, 3 ports, and even 4), as they allow for charging and, in some cases, powering various low-power devices — smartphones, tablets, power banks, lamps, and more.

— Current Strength. The maximum current delivered through the USB-A connector to the charging device. Note that different ports of the charging station may output different currents (for example, 1.5 A and 2.1 A). In such cases, the highest current strength is usually specified.

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

Full-sized USB-A ports with fast charging support. This feature allows you to charge your smartphone, tablet, or other connected devices much more quickly. The charging process occurs at increased power, with current and voltage regulated at each stage to stay within optimal values. However, keep in mind that there are many fast-charging technologies today, and not all of them are compatible with each other.

— Current strength. The current parameters delivered through USB-A fast charging ports. Note that different ports of the charging station may output different voltage and current parameters. This section specifies the current strength values at a certain voltage (for example, 5V / 3A, 9V / 2A, 12V / 1.5A).

— Power. The maximum power in watts (W) that the charging station can deliver through the USB-A fast charging port to a single charging gadget. High output power allows for faster charging. However, the charging device must support the corresponding power; otherwise, the speed will be limited by the gadget's characteristics.

USB type C ports are smaller compared to classic USB ports and have a convenient reversible design that allows connecting the plug either way. USB type C was initially created to implement various advanced features: increased power, fast charging technologies, etc.

Since the port is relatively new and quite powerful (you can find USB type C with 60W, even 100W and 140W), the total number of such connectors is often limited to one port, or sometimes two).

— Current. The maximum current delivered through the USB type C port to the device being charged. Note that different ports of a charging station may deliver different currents (for example, 1.5A and 2.1A). In such cases, the highest current is usually specified.

— Power. The maximum power in watts (W) that the charging station can deliver to one charging gadget. The high output power of the USB type C port allows for faster charging. However, the device being charged must support the corresponding power; otherwise, the speed of the process will be limited by the gadget's specifications.

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.

A large two-pole connector for connecting batteries, chargers and all kinds of equipment where reliable contact is required for the sake of ensuring stable operation of the equipment. Anderson Port is resistant to moisture changes, can be used both for indoor and outdoor mechanisms. Thanks to identical mating parts, a pair is formed by two identical connectors, which are rotated 180 ° relative to each other. Most often, Anderson port is used in mobile homes on wheels.

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