2# Cause: Low-quality charger
Actions: Change with certified charger.
Please be aware of the charger specification and do not use low-quality one that can have spikes of high voltage coming through. It might burn the chip and cause malfunction of the device.
If the chip is completely burnt, there will be no reaction when charging. For partial damage of chip due to the higher voltage, there could be an issue not charging or charging time is much longer than usual.
POWER is not yet tolerant to low-quality chargers but we are improving it.
Tips: If the charger is needed, try to use the branded and certified one for 5V.
