Home made led light with 5w phone charger watt usage? Answered
I have a led bulb which is 5w and I also have a homemade light bulb powered by a phone charger say also 5w. Question is Am I really saving any energy by using a phone charger unit it states it uses 5w? am I using 5w while is plugged 5w or am I using mAX OF 5W OF IT?
DOES IT ALSO use 5w when it is only plugged but not powering my led bulbs . bulbs 5v 1 amp, 50 leds.
thanks in advance.
Also do you know a way to make a water proof glue at home?
