USB chargers have revolutionised how we power our devices, and car USB chargers now offer us unparalleled convenience and versatility. These compact and adaptable chargers have become an indispensable part of our daily lives, allowing us easy and convenient access to power for the multitude of devices we rely on daily. USB chargers were initially designed for computers and peripherals but have since been developed to cater for many devices, from smartphones and tablets to smartwatches and portable gaming consoles, not to mention keeping our in-car entertainment devices powered.
A bit of technical background: The fundamental design of USB chargers revolves around the Universal Serial Bus (USB) standard, a ubiquitous interface for connecting devices and transferring data. These chargers utilize USB ports and USB cables to deliver power, mixing various technologies such as Power Delivery (PD) and Quick Charge to optimize charging speeds and adapt to the energy needs of different devices. Their compact size and multiple ports enable users to charge multiple devices simultaneously, conveniently and effectively. Additionally, advancements in USB charger technology continue, introducing faster charging protocols, smarter power management, and enhanced safety features to meet the evolving demands of consumers.
As our reliance on portable electronics grows, USB chargers and USB adapters remain at the forefront of powering our digital lives. Their universal compatibility and ability to deliver power efficiently have made them a cornerstone of modern technology, enabling users to charge their devices on the go. So here are some of the best car USB chargers available just now.

Some things to consider with USB plugs:
Number of Ports: Think about how many devices you’ll likely need to charge simultaneously. Car chargers can range from single-port to multi-port options.
Output Power and Compatibility: Check the output power of the charger. Higher current (measured in Amps) generally means faster charging. Some devices may require specific amperage levels for optimal charging. Check compatibility, especially if you have devices that support fast charging or have unique power requirements.
Size and Design: Consider the size and design of the charger. A compact and low-profile design not only looks better but if it doesn’t protrude too much from the car’s power socket, then it’s less likely to interfere with other controls or outlets in your vehicle.
Additional Features: Some chargers come with extra features like LED lights, built-in cables, or Quick Charge technology. Decide if these features are needed or if you prefer a straightforward, no-frills charger.
Device Compatibility: Ensure the charger is compatible with the devices you intend to charge. Some devices (like wireless phone chargers) may require specific types of USB ports or charging protocols, so compatibility is important.
Will a USB charger drain my car battery?
While your car is running, there is no problem because the alternator is charging the car battery. A USB charger will draw a little power from a car’s battery but not anything significant. With electric cars, it’s a similar story, though you need to remember any power drain is being taken directly from the batteries that fuel the car.
When the engine is off, it’s a similar story, although some cars won’t allow charging while switched off. If you want a power supply for charging devices when a car is off or in any other relevant circumstance, it’s worth considering investing in a power bank.
