If your saber will not charge please follow the following troubleshooting steps. Remove the bottom half of the hilt and remove the battery, reinsert the battery and try and charge. Please make sure the two set screws behind the buttons are fully inserted so when attaching the charging chord good contact is made. If your saber has gone completely dead it will take a few minutes to announce 'Charging' and the buttons will not light up at first. Leave your saber plugged in for at least 10 minutes. Please use the USB-C cable that came with your saber. Some USB-C cables do not carry power and will not charge the saber. If your saber 'clicks' or 'chirps' when plugged it it is probably very low on battery. The saber is trying to announce 'Charging' but doesn't have enough power to do so. Leave your saber plugged in for at least 10 minutes and it should continue to charge.
