Mpow’s newest portable Wireless Bluetooth speaker is on sale today. It’s on sale for just $45.99. That’s about half of the normal price. This speaker has Bluetooth 4.0, so it’s pretty good on battery for both the speaker and the device that you are using with it, i.e. your smartphone. As far as battery life goes, it will last about 8 hours of continuous use. Also it’ll shut off after 10 minutes of no activity. Which is good for those that forget to turn off their speaker. On the side it has the on/off switch as well as the 3.5mm jack and a microUSB port for charging the speaker. It’s a really nice looking speaker. While I haven’t reviewed this speaker from Mpow, I have reviewed another smaller one – which is priced at around $25 normally – and it was amazing. So I’d expect the same out of this one.
