This discounted FM transmitter streams your music, charges your phone, and humidifies your car for just $13

If you're driving an older car, your built-in stereo may lack Bluetooth meaning you're stuck tuning into the local radio whenever you're on the road. But you don't have to be with this discounted Bluetooth FM transmitter (opens in new tab). It regularly sells for $22, but if you click through this link (opens in new tab) you'll see an offer for 60% off, taking it down to just $13.19. Add it to your cart and you'll see the discount reflected at checkout.

It's really easy to use and will fit into most car cupholders. To get it working, you connect your phone to the transmitter via Bluetooth. All you have to do then is set your car's radio and the transmitter to an unused frequency in your area and, voilà, you're streaming your own music on your janky old car stereo. You can also use it to take hands-free calls thanks to a built-in mic all while keeping your phone topped up along the way via its USB port. If you want to keep some music stored locally, rather than hooking up your phone to stream it, there's support for microSD cards and USB sticks, as well as an Aux In port.

That's not all, though. The device also works as a car humidifier and has a 300ml water tank inside it. It can run for 4 hours continuously or 8 hours intermittently to keep your car cool on a hot summer's day.
