Calverts Electrical Appliances

I am using an Eero calvert electrical appliance and have been using it for a few months.

It has been working fine for me.

I have a couple of problems.1) Its not being fully powered.

I have to adjust the output from the plug to get it to be fully powered to power the power switch.2) Its still charging the battery every time I use it.

I get about 6 amps when the charger is plugged into the outlet.

I put it on and turn it on, turn it off, turn on, off, off.

It isnt charging.3) Its going through a lot of cycles in the AC wall.

It takes about 6 hours to fully charge.4) Its making noise and the noise makes me think that its going to burst.

When I do the cycle, I feel like I am going to faint.5) I dont know if its connected to a power socket or not.

I am not sure if its a power cable or not and amnt sure what it looks like.

Any ideas?
