I would like to share my experience with the Bluetooth speaker from the MPOW here. The speaker will be delivered well protected in a small cardboard box. Supplied located next to the speaker, a micro USB cable, a phone cable, a carabiner, and an instruction manual. The MPOW Bluetooth Speaker has an integrated lithium battery and can be charged via the included Micro USB cable. The manufacturer specifies a maximum running time of 8 hours per battery charge for the equipment. I could not reach this value during operation. The battery made limp after about 6 hours. Nevertheless, I consider least 6 hours power for as a speaker for acceptable. Connecting to a smartphone designed absolutely no problem, because the speaker was found immediately and no code had to be entered. The operation is kept simple and the sound quality is more than satisfactory. All in all I am satisfied with the Bluetooth speakers and can recommend it without hesitation VERY.
