Did your Aqueon aquarium hood's power adapter quit on you? Don't sweat it, this Onerbl replacement is here to save the day. This is a brand new, high-quality 12V AC/DC power adapter designed to work with a bunch of Aqueon Deluxe LED hood models. Check your old adapter – if the part number is something like 21105, 100121105, 277006, 21101, 100121101, 21107, 277008, or it's for their 20-inch, 24-inch, 30-inch, or 36-inch Full Hood LED strip lights, this should be the right one. It takes standard wall power (Input: 100-240V, 50/60Hz – so it works worldwide) and converts it to the 12V DC your light needs. It's got built-in protections against over-voltage and overheating to keep your gear safe. It's been tested to make sure it works great. Super straightforward – just plug it in and get your aquarium lit up again. A total lifesaver if your original charger got lost or stopped working. No more sitting in the dark, fish friends!
