3.7 VOLT BATTERY POWERS 56 WATTS

[Zephir]

Hi Magnetman, this is all very impressive at the first look - but could you please measure the actual current drawn from your USB adapter with digital multimeter? Normal USB port allows only 1 A so that no more than 5 watts should appear at its output. But the cheap Chinese powerbanks lack the overload protection, so that the actual current can be much higher. Also the nominal power load of your LEDS (7 watts each) may not correspond their actual load at all. Tomorrow I'll try to complete more professional documentation of your project from this forum - as there is still lotta white spots in my understanding of your circuit. 

For example it's not clear for me, how the air core coil gets actually wired into your circuit. Do you use both colored wires in parallel?
Thank You indeed for your reply in advance.

Hi naija, i just noticed your reply, thanks for the kind words.
It works fine with an air core, i would use 24 awg. magnet wire or the telephone wire like magnetman, if you can't get any magnet wire.
I would also use the brooks coil geometry for an air core coil, i didn't, because i wound it for the option to slide in my ferrite c-core.
The components shown or equivalent should be fine, since the capacitor shown has high enough voltage rating and those 220 volt led bulbs will be using less amperage.
The only question is, will the led bulbs you use work properly with the circuit, if not, you may need to remove the inner circuitry and just drive the leds directly with the diode/capacitor output.
I plan to use the 12 volt led bulbs i should be getting in mail soon and also plan to more closely build the magnetman circuit.
peace love light

Thanks Skywatcher for the clarifications.

Added another bulb.  63 watts now powered by 5 volt  USB adapter.

Hi Magnetman,

Your work is fast becoming an attention grabber, 63W of light power from probably a little more than 5W of dc power! Am starting to collate the materials needed to replicate your work EXACTLY. Thanks for sharing this idea. While sourcing the materials for this, I came across two types of 1k 0.5w potentiometer, one has a rated working voltage of 50V while the other has rated maximum voltage of 500V; which of these will you recommend?

Please may I know if your circuit can also run a 12 vdc fan of say 30 - 60W capacity at full power?

Thanks in earnest anticipation of your response

Hi Naija,
Be sure the pot is a linear taper pot. Not audio taper.   Here is what I used:  This particular dealer sells both the 1K  and 10 k pots.  In your case either will work if its linear taper.

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.

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!
