How does one know if it's charged without trying to charge it or activate it?

I found the answer- when you're charging it- there's a little red dot light that goes on... I'm assuming it will turn either blue or green when the alarm is fully charged. Other than that, I don't know how one can tell. Maybe make a note on your calendar to charge it every year.

What type of adapter plug is needed for the USB cord?

Hello, Adapter plug with 5v is required (the one used for cellphones should be good). Regards, WETEN Customer Support

How do I know once it’s fully charged? I plugged it in and there was an orange light and now the orange light went away, does that mean it’s charged?

Dear customer, Exactly, when the red-orange light goes away, it means the alarm is charged. Happy Holidays, WETEN Customer Service

I plug in the device, but, within minutes, the red light goes off. i unplug it. plug it back in. red light comes on again. charging malfunction?

Hello, It is OK for the red light to go off within minutes, it means that the device was almost fully charged. But the red light should NOT come on again when you plug the device back in. I see that you purchased a pack of 2 alarms (however, I don't see the order number), so please contact us through Amazon buyer-seller messaging system for further discussion and resolution. Regards, WETEN Customer Service
