Your Raspberry needs a constant flow of energy. Why is an efficient power supply for Raspberry Pi Zero important?
For the Raspberry Pi Zero to work properly, you need a power supply with 4.75-5.25 V, 0.7-1 A (model B) / 0.5 A (model A) and a microUSB plug, or an adapter. So it seems that the choice is not difficult. However, it turns out that the power supplies are very different from each other and the question is whether the parameters of the selected model, as well as the quality of its manufacture, will meet the requirements of Raspberry Pi Zero. Power supplies are devices designed to adjust the voltage to the needs of the device to be powered. The power must be adapted to your individual needs. A lot depends on the purpose of the Raspberry Pi Zero and the area in which we use it. The power of the power supply is responsible for ensuring that your device will work efficiently using its full potential. You must also know that it is virtually impossible for the components to be supplied with 100% of the energy consumed. For example, the efficiency of the power supply can be estimated at 80%. In such a situation, 80% goes to the components, and 20% is lost. It is obvious that the higher the efficiency, the more effective the Raspberry Pi Zero works. The power supply also affects the safety of the minicomputer. We rarely identify safety with a power supply, concentrating only on its primary function, i.e. providing energy. The power supply must be stable and solid; only then the components will work efficiently. There are cases where, if the power supply is inadequate, a serious failure occurs.
USB cable and efficiency of the power supply for Raspberry Pi Zero
When you choose a power supply for the Raspberry Pi Zero, you should not forget that the USB cable is responsible for its correct operation. It connects the power supply to the Raspberry Pi Zero. It is an inexpensive component that plays an important role in the operation of the whole device, especially in the efficiency of its power supply. Therefore, it is worth choosing a model that stands out for its good quality, especially since its price will not affect your limited budget. If you decide on cheaper models, you can expect a transmission rate of 0.2-0.5 A. You must know that this is far too little and not enough for the equipment to work properly. You'll quickly find out that its efficiency is decreasing or and even failure may occur. Moreover, the role of the power supply itself should not be underestimated, which is important both in terms of output voltage and current capacity.
Our offer includes a wide range of power supplies for the Raspberry Pi Zero, which are distinguished by very good technical parameters. They are also compatible with other models of Raspberry Pi minicomputers, so you can often use one power supply with two or more computers.
