Lost or broke the charger for your SENSEAR electronic hearing protector (like the SM, SM1, SM1x, SP, SP2 models)? This SLLEA adapter is a perfect replacement. It's a universal input power supply, meaning it works with any outlet from 100 to 240 volts, so you can use it at home or while traveling abroad. It's a high-quality, non-OEM (not original manufacturer) part that's been tested to work safely with your device. It has built-in protections against over-voltage and overheating for safety. The cord is a decent length, and the whole thing is lightweight and portable. It's CE certified. Just plug it into the wall, and connect the barrel plug to your SENSEAR unit to power it or charge its battery. It ships from the USA. They offer a great warranty too: 30-day money-back, 60-day free exchange, and a 360-day worry-free guarantee. Double-check the plug size matches your device before ordering.
