Comparison Dabbsson DBS1300 vs Oukitel P1201

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.

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”.

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.

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

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.

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.
