I can't really recommend one but I'm sure you can find one in Target and Walmart, or Amazon. Just need to make sure that it matches the input voltage of our G-BOOM which is 12V and to charge you need a 12V output voltage from its output port.
For G-BOOM, you have USB port and one DC jack at the unit back. You need a charger to connect to the DC jack to charge it as the USB port is for OUTPUT only.
