3.7 VOLT BATTERY POWERS 56 WATTS

[magnetman12003]

Thanks very much man; whatever you choose to call this circuit, just make sure it's got your name on it! This invention can immortalize you!

Just today using only my LUMSING  5 volt USB 17 watt wall adapter I ran a few tests using the 9 seven watt 12 volt led bulbs once more.  During this test ALL bulbs burned brightly.  I found 5.19 volts/1.26 amps at the USB charger output. All bulbs lit.    I found 3.30 volts/1.26 amps across the C1 capacitor.  Once again this is with all bulbs lit.  So we have 6.5394 watts feeding this circuit- that's the output of the 17 watt USB wall adapter.  No wonder the adapter feels cold to the touch.   4.158 watts across the C1 shows the setup is using 2.3814 watts to power itself.  THE REAL QUESTION TO ASK IS HOW IS THIS POSSIBLE CONSIDERING THE FACT THAT CLOSE TO 63 WATTS ARE NEEDED  TO POWER THE BULBS?    4 TO 6+ WATTS SHOULD NOT DO THIS??

I hope everyone gets involved with this and it goes viral.  I only want to be noted as the person that used
tidbits of information from others and after adding my own thoughts I came up with this"" HYBRID"" circuit. I hope it works out for all mankind.  That's why I open sourced all info.

I gave up exploring what the setup will do with 12 volts after using the 5 volt wall type USB  adapter. Currently I am powering  nine-- seven watt -- 12 volt led bulbs totals 63 watts.  All lamps are brightly lit for some strange reason so I guess I will push on and see how many more can be lit the same way.  My Lumsing USB wall power adapter is rated at 5 volts at 3.4 amps.  THATS  17 WATTS DRIVING 63 WATTS??  CRAZY!!   The USB power adapter runs cold to the touch after long use!  Should I call this a power assister circuit??  Open for a good name.

Dear magnetman,

Indeed it sounds crazy (17W driving 63W) because you have not managed to measure the actual power drawn by the 9 LED bulbs.  As I wrote earlier, the voltage and current waveforms can be saw tooth shaped as the thyristor switch periodically discharges the C1 puffer capacitor and this waveform cannot be measured correctly by normal DMMs. 
Remember you reported 3.8V or so DC voltage measured inside one of a LED socket while the other LEDs were nicely lit  i.e. 3.8V or so voltage amplitude could not drive any such LED with nice brightness. 
This is why I tried to suggest using a second filter capacitor, C2 to filter and smooth the saw tooth voltage to be more DC like so that both the current and voltage values driving the LEDs could better be measured by a DMM once there is no oscilloscope available for you.

Hi magnetman,

you wrote:  "4.158 watts across the C1 shows the setup is using 2.3814 watts to power itself. "

it is okay that there is typo, it is 4.158 Volt across C1 what you measured by your DC voltmeter right?

This is what am saying: the saw tooth like waveform across C1 may fool the DC meter, very possible. 

Addition:  If I recall correctly, you already wrote somewhere that if you try to drive a 12V LED bulb from say the 5V USB device, it remains fully dark?  i.e. not working

3.30 volts x 1.26 amps = 4.158 watts across the C1 cap    6.5394 watts across the output of the USB adapter.  6.5394 - 4.158 = 2.3814  watts consumed by setup.  All measured by true RMS multi meter.

Okay, I understand now how you calculated the 4.158 W across the C1 capacitor.

However, I disagree with the way you attempted to calculate the power drawn from C1 because the 1.26 A is the input from the 5V USB device.  You would have to measure the current at say its negative leg where it connects to the cathode (K) of the thyristor, at that point the ampermeter could be inserted and see the rms current. 
A question: the 3.3 V across C1 is a DC value or  rms AC value?

Thanks,
