50W BassUp Output, Floating Wave Performance & IP68 Saltwater Protection
The Soundcore Boom 3i from Anker is a rugged 50W outdoor Bluetooth speaker built for adventures on land and water. Available in the Bluetooth speakers collection at Umrelo, it combines powerful acoustics with extreme environmental durability.
Featuring BassUp™ 2.0 technology, the Boom 3i delivers bass down to 56 Hz and reaches up to 96 dB loudness.

Frequently Asked Questions
Can the Anker Soundcore Boom 3i really float on water while playing music?
Yes. Unlike standard IP68 speakers that merely survive water submersion, the Boom 3i is engineered to auto-correct to an upright position in waves, keeping its drivers facing forward so sound remains clear and undistorted.
How long does the battery last on a full charge?
The battery provides up to 16 hours of playback with RGB lights turned off. With the light show active, battery life is approximately 5.5 hours. A full recharge takes about 3.2 hours via USB-C.
Does the speaker support AUX input or speakerphone calls?
No. The USB-C port is for charging only, and there is no 3.5mm AUX input or built-in microphone for phone calls. It functions as a pure wireless Bluetooth music speaker.

Anker FAQs
Are Anker products at Umrelo genuine, and do they have warranty?
Yes. Umrelo sells genuine Anker products sourced from trusted distributors. Items marked "Official Warranty" are covered by Anker's manufacturer warranty in Bangladesh, and other genuine items carry the warranty stated on their product page. See all official warranty Anker products or read our warranty policy.
Are Anker chargers and cables good for iPhone?
Yes. iPhone 8 and newer can fast charge using USB Power Delivery. iPhone 15 and newer use USB-C, so a USB-C charger with a USB-C cable works. For iPhones with a Lightning port, use a 20W or higher PD charger with a USB-C to Lightning cable, and choose an MFi-certified one. Browse our wall chargers and Lightning cables, and check the product page for output and cable type.
Which Anker charger or power bank should I buy?
For phones, a 20W to 35W GaN charger is usually enough. For laptops and tablets, look for 65W or more. For daily use, a 10,000 mAh power bank balances size and capacity, and 20,000 mAh suits travel or heavy use. Each product page lists the output and ports, and our team is happy to help you choose.
