Thanks for the response.
I don't know how to check if the battery is fully charged. I'll leave it on the charger for a few hours to see if it makes a difference, but I don't see what difference the battery charge would make. Especially when running it while plugged into the charger. The LED on the power switch does illuminate, just no sound at all...
From what I understood the adaptor is only there to charge the battery, you always need to rely on the battery for the power supply even when you have your amp plugged in. While the amp is plug in it will discharge and discharge on the go. Therefore starting off with a fully charge is essential. Just leave it over night charging and have it off that should work.
I hope in future revision Cesar modifies his amp so it does not rely on the battery when it is plugged in.
PS:had a typo on my previous port, i meant "now loving it".
portaphile has incredibly dynamic sound and it is open and natural.
