The portable Bluetooth speaker by Anker with a power of 40 watts is full range and can reproduce any music track, though with limited bass performance as it does not have a subwoofer. With a full charge, it offers up to 12 hours of continuous music playback. Additionally, it has USB charging capability, allowing you to easily charge it with a power bank. With an IPX7 protection rating, you can take the speaker with you to the beach or pool as it withstands 30 minutes in water at a depth of up to 1 meter. Note that movement in the water creates increased pressure as if it were at a greater depth.
