Comparison EcoFlow DELTA Max 1600 vs EcoFlow DELTA Max 2000

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.

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.

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

— External. Outdoor placement of the power supply requires additional space. However, most blocks of this type are quite compact in size and are equipped with “plugs” for sockets right on the case - in other words, the block is installed on a socket, and from there the wire stretches to the charging station. There are also external power supplies on the cable. Considering that you only need to connect the adapter while the device is charging, an external power supply is a very convenient solution.

- Internal. The built-in power supply does not take up space outside the charging station, however, it can increase the dimensions and weight of the device. The advantage of this arrangement is that the most common power wire goes from the housing to the socket, without additional equipment on it. At one end it is connected to the socket, the other end is connected to the input connector of the charging station.
