Hi
@Tarpey, sorry for not being able to reply you earlier.
According to the information you mentioned above, here are some steps for troubleshooting:
1). Please figure out whether this happened when the battery is fully charged or almost run out of battery; cause it may happen when the battery is running out of power and it will automatically shuts down under high-power output, or the battery ratio is not enough to drive high-power output then it will shut down itself. Therefore, please try to use fully charged battery, if the problem still happens please go to next step.
2) Try to use with other batteries, such as: the Sony VTC Series (VTC4,VTC5,VTC6). If it still gets the issue, then please adjust the wattage to 10W to make sure the battery ratio is enough to support the output.
3). If you have tried the above steps, it still does not work normally, please email to
support@innokin.com for warranty inquiry.
Any other questions, please feel free to DM me or email to

Thank you!
