All mechanical and electronic systems require power. Without it, they cannot work. They need an energy source that drives them to operate. It is impossible to construct a machine that would work continuously without any energy source. With the development of technology, more and more sources of energy are emerging, which makes mobile devices that do not require a permanent power supply. These are accumulators and batteries, thanks to which we can use the device anytime and anywhere. They are perfect for mobile robots and mobile devices. Alternatively, there are power supplies, which in turn are plugged into an electrical outlet to provide power to the device, then it starts to work. A modern and at the same time inexhaustible source of energy is the sun. More and more often solar panels appear on the roofs of a building, whose task is to collect solar energy and convert it into electricity. Similar, but smaller panels are used in devices and machines, as well as to charge car batteries.

In the past, the electronics market was dominated by ordinary (disposable) batteries and nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) batteries. The popularization of lithium-polymer (Li-Po) and lithium-ion (Li-Ion) batteries with small dimensions and weight and huge capacities, unattainable for other types of batteries, has caused a revolution - both in the category of mobile devices and RC models and robotics amateur. In this category you will find a wide range of batteries of all types mentioned, as well as various types of batteries in the most common dimensional standards. You will also find large gel batteries here.
Chargers for all types of batteries
Once you have selected the battery, you must also equip yourself with a charger appropriate to its characteristics and size. Our offer includes both chargers for modeling packages and classic "finger" batteries in sizes R6 and R03. We also have special chargers dedicated to car batteries, including modern gel batteries, which have effectively replaced the old lead-acid designs from the market. In addition to ready-made devices, you will also find various types of charger modules that will allow you to easily build a charging function into your device (e.g. a robot), without having to worry about designing the necessary safeguards to protect the battery against overheating or even explosion. This category included probably the most popular types of chargers - micro USB and USB C, as well as wireless ones dedicated to mobile devices.
Power supplies from A to Z
Our offer of power supply components and devices would not be complete if we did not provide all types of power supplies, used not only in connection with everyday devices, but also in electronics services and design studios. Here you will find a wide range of single- and multi-output laboratory power supplies, ATX computer power supplies, as well as uninterruptible power supplies (UPS) used to protect computer equipment or measuring equipment. We also have a wide range of power supplies for wall sockets (plugs), as well as industrial and automotive power supplies.
Power - FAQ
When selecting a power supply for any device, check what power parameters it requires. First of all, you need to take into account the type of power supply (AC or DC), current efficiency (amperage) and voltage, as well as select a power cable with appropriate capacity and with the right connector .
