Fifty watts in a rugged shell
Look, 50W from a portable Bluetooth speaker is not nothing. The Boom 3i sits in that sweet spot where it's loud enough to fill a garden or a campsite without needing a mains socket nearby. Anker's Soundcore sub-brand has been quietly putting out decent kit for a few years now, and this one caught proper community heat on HotUKDeals, nearly 800 votes. That's not accidental.
IP68 waterproofing means fully submersible up to 1.5 metres. So rain, mud, someone knocking it into the paddling pool, it handles all of it. I've had a similar Soundcore speaker sit outside through an entire British summer weekend, showers included, and it came back absolutely fine. This one's rated even higher.
Who it's actually for
This is for the person who takes their music seriously outdoors. Festivals, beach trips, allotment sessions. The build looks chunky and purposeful, not a pretty living room piece.
Honestly, if you mainly listen inside or just want background noise for a dinner party, you don't need this. A smaller speaker will do, and you'll save yourself the bulk.
One reservation worth flagging: there's no published "was price" listed here, so I can't verify the actual saving. Early Prime Day pricing is sometimes a bit theatrical. Worth keeping an eye on CamelCamelCamel before committing.
At around fifty quid for 50W and a proper IP68 rating though, it's not half bad if outdoor audio is genuinely your thing.
