What is a DC power supply and what is it used for?
DC chargers are mains power supplies that convert alternating current from a power socket into the direct current required by electronic devices. If you are looking for a reliable power source for a CCTV camera, router, LED strip or laptop with USB-C, Akyga® offers models suitable for every application.
DC chargers – what models can you find in the Akyga® range?
Akyga® offers a wide range of AC/DC power supplies with various parameters. Products in this category include models with output voltages of 5 V, 12 V and 24 V, which allows them to power virtually any type of electronic device.
In terms of power, the DC chargers in our range offer outputs from 10 W to around 90 W. This makes it easy to match the power supply to both small mobile devices and demanding monitoring systems or lighting installations.
The manufacturer has ensured compatibility with popular DC connectors – you will find models with 5.5×2.1 mm, 5.5×2.5 mm and 3.5×1.35 mm plugs. In addition, the range includes modern USB-C chargers with Power Delivery and Quick Charge support, ideal for laptops and new-generation mobile devices.
There are two main types of designs on the market – classic power supplies and compact models made using GaN technology. Specialised chargers are designed for CCTV systems, network devices, and LED lighting in domestic and commercial applications.
What DC charger parameters should you choose for your device?
The correct selection of a DC charger requires checking several key parameters. The output voltage must exactly match the requirements of the powered device – standard values are 5 V for mobile equipment, 12 V for cameras and routers, and 24 V for LED installations and industrial devices.
The current and power of the power supply should be at least equal to or higher than the requirements of the equipment. A 30 W charger will safely power a device that consumes 25 W, but will not work with equipment that requires 40 W.
The type of DC connector is another consideration. Before purchasing, measure the outer and inner diameters of the original power supply plug or check the device specifications. Typically, CCTV cameras use a 5.5×2.1 mm connector, while some network equipment requires smaller plugs.
Checking the polarity is essential for safety – in most devices, the positive terminal is located on the middle pin, but some products have reversed polarity. This information can be found on the device's rating plate.
For use in shopping centres, hotels or medical facilities, choose chargers that have the appropriate safety certifications and meet industry standards.
DC charger – classic or modern GaN technology?
The choice between traditional power supplies and modern impulse models affects user comfort and energy efficiency. Classic DC chargers are popular in regular sales thanks to their proven design and affordable price, but they take up more space and generate more heat.
GaN (gallium nitride) technology is revolutionising the power supply market. Chargers manufactured using this technology are significantly smaller while maintaining high power and higher energy efficiency, which translates into lower heat loss.
In terms of reliability, both technologies ensure long operating times when used correctly. GaN models also tolerate thermal loads better thanks to more efficient heat dissipation.
If your devices are equipped with a USB-C port, choose a charger that supports Power Delivery – this standard enables smart charging with automatic parameter adjustment. Quick Charge standards ensure fast charging of mobile devices compatible with this technology.
DC chargers for home and office use
In the home and office environment, DC chargers are used for a range of everyday applications. Laptops and tablets are best powered by USB-C chargers with Power Delivery – a single compact 65W or higher power supply will handle most modern portable computers.
Routers, modems, and switches in home networks usually require 12 V DC power supplies with a cylindrical connector. The Akyga® range includes models that are perfectly suited to popular network devices currently available on the market.
LED strips and decorative lighting require a stable 12 V or 24 V power supply, depending on the type of installation. For longer LED strips, choose power supplies with a correspondingly higher power rating to avoid brightness drops at the end of the strip.
Power banks and mobile devices are charged using 5 V models with power adjusted to the battery capacity – fast chargers with Quick Charge significantly reduce the time needed to recharge.
Cable organisation and secure installation are factors that affect user comfort – use cable ties and guides, and avoid bending cables at sharp angles. Universal chargers with interchangeable DC tips allow you to power multiple devices with a single power supply, further reducing the number of cables.
DC chargers for professional and industrial applications
Professional installations require power supplies with enhanced reliability and safety parameters. CCTV monitoring systems – cameras, recorders and control panels – operate continuously, so they need power supplies that provide stable voltage around the clock, year after year.
Commercial and industrial LED installations in places such as offices, shopping centres and hotels require high-power, high-efficiency power supplies. Akyga® products in this category provide reliable power even for complex lighting systems.
In telecommunications – GSM signal amplifiers, network infrastructure, access devices – power supply stability directly affects service quality. DC chargers in this category meet the requirements of the business environment.
OVP, OCP, OPP, OTP and SCP protections are standard in power supplies designed for professional use. They protect both the powered devices and the power supply itself from damage caused by overvoltage, overload or short circuits.
For service technicians and installers of electronic systems, the manufacturer's warranty and the availability of compatible models in regular sale are of key importance. As a manufacturer, Akyga® ensures continuity of supply and technical support.
CE and RoHS certifications and safety standards compliant with EU requirements confirm that products in this category are suitable for professional applications requiring documentation and regulatory compliance. Add your chosen model to your basket and order a power supply tailored to your needs.
