Hey tech folks! This EXMAX USB to 3.5mm barrel jack adapter is one of those simple but incredibly useful cables that solves so many power problems. It converts standard USB power to a 3.5mm barrel connector that works with all sorts of small electronics and devices. The barrel jack has an outside diameter of 3.5mm and inside diameter of 1.35mm, which is a pretty common size for many gadgets. It delivers 5V DC power and can handle between 1A to 2A, giving you a stable and reliable power supply for your devices. The cable itself is about 120cm long (that's nearly 4 feet), giving you plenty of reach to connect your devices comfortably. So what can you power with this? Well, it's specifically mentioned as working with WDT-99 transmitters and receivers, but it's also perfect for USB lights, small fans, cartoon clocks, radiators, portable power devices, MP4/MP5 players, and various other electronics that use this common barrel jack size. The connectors are nickel-plated, which not only looks good but also provides better durability and corrosion resistance for longer service life. Inside, it uses pure copper cores that ensure fast and efficient power transmission without voltage drop issues. It's basically plug and play - no drivers or complicated setup needed. Just plug the USB end into any USB port (computer, wall charger, power bank, etc.) and you've got instant power for your device. This is especially handy when you've lost the original power adapter for something but still have plenty of USB ports available. The build quality feels substantial - it's not one of those flimsy cables that'll fall apart after a few uses. If you're tired of dealing with multiple proprietary power adapters cluttering your space, or if you just need a reliable way to power your small electronics from USB sources, this adapter cable is an absolute game-changer. It's one of those 'why didn't I get this sooner' products that makes your tech life so much easier!
