 The BQ-24074 USB DC and solar battery charger. Super cool feature of this is, of course, solar. This second JST connector here allows you to hook up something that wants that 3.7 volts off of the battery. And in this case, I'm going to plug in one of our little USB power boosts. So this is now converting whatever's coming off that battery. And now I can plug some USB whatever into it. So you could charge a phone off of here. In this case, I've got one of my little Korg NTS-1 synths plugged into here. And so now, right, I've got a USB device. I'm in the sun. I'm charging. I'm running this off of here. I'm charging the battery. So I'm running off of a stable supply. Product pick of the week this week, it's the BQ-24074 universal charger with DC, USB and solar.
