24-volt power USB cables are used to power devices that work on 24V DC. These cables integrate a power supply circuit (converter) that drops 24 volts to the 5 volts required to run a standard USB device. They are primarily used in industrial applications where a 24V system is common. Prolific and FTDI are examples of manufacturers of 24v powered USB cables.
There are two main types of 24-volt powered USB cables:
Since not all 24v USB cables are the same, knowing how to distinguish a powered USB cable from a regular data transfer cable is important. Power or charging USB cables have a power transmission circuit inside them. These cables are designed to work with power adapters to charge devices quickly, while regular USB cables are mainly for data transfer.
24-volt USB cables are useful for many applications. Here are some of the features and functions of these cables:
Power Supply Conversion
The primary function of a 24v USB cable is to convert 24 volts from a DC power source, such as an automotive battery, into a voltage suitable for USB devices. Most USB devices operate between 4.75V and 5.25V. This cable allows the user to charge these devices at 24 volts.
Built-in Voltage Regulator
24V-powered USB cables come with a voltage regulator. This component regulates and stabilizes the output voltage to the required 5 volts. It thereby protects the connected devices from any damage that may occur due to excessive voltage.
Other voltage regulation components in these cables include linear regulators and switching voltage regulators. These regulators make sure that the devices get a steady 5 volts, even if the 24 volts is not steady. The cable adapts to changes so it won't harm the device.
Current Capacity
The current capacity refers to how much current the cable can safely carry. This depends on the gauge or thickness of the cable. A qualified cable should have a current capacity of 2A, 3A, or even higher. This ensures efficient charging and data transfer.
Quality Connectors
24v USB cables have quality connectors for reliable data transfer and charging. The most common connectors in these cables are the Type-C, Type-A, and Type-B. They ensure sturdy connections. The connectors enable the user to connect tablets, phones, and other devices not powered by 24v directly.
Durability
24-volt USB cables are built to last. Many of them have reinforced connectors and a thick insulation sheath. These cables are not prone to fraying or damage from frequent bending. Also, the cables are easy to use. Users don't need to worry about which way to plug a Type-C connector.
Data Transfer
Some models of the 24-volt USB cable also allow data transfer. They enable the user to back up data, sync files from the phone to a tablet, and download updates. They do both charging and data transfer, which makes them versatile.
Length Varieties
These USB cables come in a range of cable lengths. Some are very short cables for use when devices are close to each other. Users with nearby 24-volt outlets and USB devices can use the cables to reduce clutter. Longer cables allow users to charge devices that are far away. The different lengths give convenient and tidy solutions for any situation.
The 24v powered USB cable can be used in various situations to ensure seamless, strong power and data transmission.

Retailers should consider several factors before buying powered 24v USB cables for their POS systems. These include compatibility, cable length, durability, charging speed, and safety features.
Compatibility
Market requirements dictate that business retailers check the compatibility of the 24v powered USB cable with the specific IBM POS models they intend to use. Ideally, most IBM POS terminals feature a 24v power input, usually through a specific DC connector. Also, retailers should ensure that the cable they are purchasing is compatible with the devices that will be connected via USB. That is, they should check that the USB connectors are compatible with the devices' USB ports, whether it's USB-A, USB-B, USB-C, or micro-USB.
Cable length
Retailers should choose the cable length based on the setup needs of their business. Ideally, they should measure the distance between the power outlet and the IBM POS terminal to determine the appropriate length. They may require longer cables to reach across countertops or to connect mobile devices. In case they need to route cables around furniture, obstacles, or through walls, they may require longer cables.
Retailers should avoid shorter cables since they may require to buy cable extensions or relocate their devices. They'll have to connect devices to power sources without travelling over long distances if they use shorter cables. If they decide to organise their spaces or update their equipment in the future, they may need to purchase new cables that are longer.
Durability
Retailers should consider the durability of 24v cables since they will be frequently used in a busy POS environment. Therefore, they should look for cables manufactured with robust materials that can withstand regular connections and disconnections without wearing out. They can go for reinforced cables that have extra protection at the connectors to prevent fraying or breaking.
Charging speed
Retailers should ensure that the cable they are purchasing can efficiently deliver power alongside the 24v AC-DC adapter to the POS terminal. They should check the cable's gauge (thickness) and quality to ensure that it supports the required power output without significant voltage drop.
Safety features
Cables and power delivery systems can potentially cause fires if they are not properly handled. Retailers should ensure that the cables they are purchasing have safety features such as short-circuit protection, overcurrent protection and overvoltage protection.
Q: How are 24v USB power adapters installed?
A: To install the 24v USB power adapter, 24 volt select the right model for the device. Ensure it is compatible with the electrical standards.
