Charging the Boost Fin Battery
You charge it just like any of your electronic devices, using a wired charger. We provide a custom 100-240V wall charger and it takes about 2 hours to fully charge the battery. Plus you don't even need to take the Boost Fin off the board. Please note that we don't recommend charging the batteries with any charger other than the one that comes with your device. Also, you can purchase a 12V car charger for $39.
