Comparison Oukitel P2001 vs 2E 2E-BS006

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-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.

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.

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.

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).

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.

The temperature range in which the charging station normally operates in normal mode. Exceeding the specified norms in any direction leads to a rapid discharge of the battery, its accelerated degradation and other unpleasant consequences.

Warranties for charging stations usually provide users with protection against manufacturing defects and malfunctions for a certain period, which may vary depending on the manufacturer. Warranty service includes free repair or replacement of components if the problem is not the user's fault. The warranty period can be from one year to several years, and it is important to consider conditions such as correct installation, use of the station for its intended purpose, and compliance with technical requirements.
