I have two identical Lost Vape Project Sub-Ohm Triade DNA 250C devices. One of them is having charging issues.
I've hooked the malfunctioning device up to the Device Monitor and here is what I've observed:
it reads a consistent voltage from the usb power supply
at about 10 second intervals it will read usb current and then quickly snap back to zero current
I've designed a theme where I can monitor these values from the device UI and this behavior is seen on all chargers that I hook it to.
Things that I've already attempted in order to resolve the issue:
different sets of batteries
high amperage USB chargers
low amperage USB chargers
updating firmware
verify that identical, functioning device behaves properly in all above tests
