Comparison Choetech BS009 vs Fossibot F3600

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.

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.

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 parameter allows you to estimate the approximate battery charging time in the mode of combined connection of a portable power station - from a power outlet and a solar panel overnight. This method of replenishing energy reserves allows you to speed up the charging process.

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.

The time required to fully (from zero to 100%) charge the battery, provided that power is supplied to the charging station from the car's cigarette lighter socket (12 V).

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

The power in watts provided when charging a device from a solar panel.

The higher the charging power, all other things being equal, the less time it will take to replenish the energy reserves in the cells of the device's own battery. This section provides the maximum power value that the charging station can accept. Accordingly, this indicator is supposed to be taken into account when choosing compatible solar panels.
