{"product_id":"adastra-l15rbt-rechargeable-bluetooth-megaphone","title":"Adastra L15RBT Rechargeable Bluetooth Megaphone","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Adastra L15RBT is a portable 15W rechargeable megaphone (also called a loudhailer or bullhorn) built for crowd control, alerts and public announcements. It's made from impact resistant ABS with a folding handle and a wrist strap, so it packs down to a compact size when you're not using it. A removable 18650 Lithium-ion battery powers the unit, and you recharge it using the supplied USB to DC lead from any standard USB charger, which means no proprietary dock to keep track of.\u003c\/p\u003e\n\u003cp\u003eThere's more here than a plain voice horn. A microphone sits at the upper rear of the unit, worked by a push-to-talk button on the rear panel, and a switchable siren function handles alerts. Top mounted USB and microSD ports let you play back mp3 files directly through the megaphone, and the 240 second loop recorder lets you record a message up to four minutes long and replay it on repeat. That's useful for repeated safety notices or event directions where you'd rather not keep talking.\u003c\/p\u003e\n\u003cp\u003eThe inbuilt Bluetooth receiver connects wirelessly to a smartphone, so you can stream audio files or use the phone as a remote microphone with one of the various Bluetooth microphone apps. Rated at 15W with a 400m range, the L15RBT weighs 530g and measures 245 x 154 x 148mm, keeping it manageable to hold for longer periods. It's a practical all-in-one tool for stewards, event staff and anyone giving information across open spaces.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003eLi-ion 3.7Vdc 1500mAh (supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecording\u003c\/td\u003e\n\u003ctd\u003eUp to 240 seconds looper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated output power\u003c\/td\u003e\n\u003ctd\u003e15W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e400m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio source\u003c\/td\u003e\n\u003ctd\u003eUSB\/microSD player \u0026amp; B\/T wireless receiver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e245mm x 154mm x 148mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.53KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e5Vdc (USB), 500mA min.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/952025UK_dfacb3b6-f553-4540-9ff2-c064b2d761bb.pdf?v=1785049765\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs the battery rechargeable and removable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
