BT509 LED Bluetooth Speaker Alarm Clock: Bluetooth 5.3 stable transmission
Oh, and it’s got this nifty trick: a 15W fast wireless charger that’ll juice up your phone faster than you can say “I need coffee.” Need to take a call? No problem. The speaker’s got your back with hands-free answering, because fumbling with your phone at 7 AM is nobody’s idea of fun. And with a 45mm speaker size and 5W output, it packs a punch that’ll surprise you—like finding out your quiet coworker has a killer karaoke voice.
Under the hood, there’s a 1800mAh battery that keeps the party going for up to 6 hours (at medium volume, because we’re not animals). And its compact size (180x80x105mm) means it won’t hog your nightstand. So yeah, it’s pretty much the Swiss Army knife of alarm clocks.
