Hi, guys
I’ve got AC70P. When enable AC power on about 40-120 watts, I get high frequency electric like buzz from my power station. Everything goes fine, no problems with power, but this buzz makes me crazy. The station is unusable in bedroom with this noise.
When the fans go faster - the buzz disappears.
Available online firmware updates are installed
Is there any newer firmware with fix?
The coolers themselves are quiet enough.
AC70P2345001277991
ARM v.2122.06
DSP v.2112.03
BMS v.2112.03
Hi @olegid , We currently don’t have firmware that can resolve this issue. Could you please record a video for us? Please disconnect the AC70P from any load, place it in an area away from other electronic devices, and try charging it so we can hear the buzzing sound it makes.
