Already had one of this speaker but gave it to my best friend as a gift as he really liked it a lot. Therefore, I've ordered the second one. The pairing with Samsung galaxy s9+ and Huawei phones was extremely fast. The sound is just perfect and can get extremely loud thanks to the 2x13Watt + 2x5Watt speakers. Didn't need to use it as a Powerbank so far but just tested it quickly and everything seems to be working fine. It will be pretty handy while outdoors to be able to charge the smartphone .
Can definitely recommend this speaker further..
