Power a USB port directly by a 12V solar panel without a battery 

Hello buddy, i come from a part of Africa where electricity supply is a big challenge .recently to light our community at night we rely mostly on solar powerd street lights. I have been wondering if its possible to charge our phones also using solar energy until i stumbled upon this video. I am going to try your method with the dc to dc converter used in cars. I hope to come back and tell u my experience. A breakthrough in this direction will alleviate a lot of suffering to my people

Can't you just put the crocodile clips onto the single usb cigarette lighters and not use the 3 cigarette ports

Hahahaa... I have almost the exact devices here that i use for the exact purpose as shown here. I guess no idea is new in the world. Cheers mate ☺ 👍

there you are !!! somehow i lost you from my subscriptions... you actually know what you are doing & you talk & tell us important info , others just play the worst music ive ever heard & never talk. also they seem to make fake things & camera trickery. im sub'ed ! glad i found you..

excellent video.....the car adapters have a t092 -78l05 5v regulator in them, i think the 7805 (bigger version) of the 5v regulator can handle more amps.....

So useful information!! I was thinking of using a garmen car plug-in for solar to phone, as it should be good quality. Would this overcharge/ruin my phone?? This device you tested looks to be better.❤

I learn so much from your channel, I can't believe I didn't think about doing this👍🏻 thank you

I've found with a smaller mobile phone if you plug a powerbank into the USB and powerbank out into the phone it keeps charging after the sun has gone in. I had a phone that only drew 130mA from the panel (about 0.5A when it's gone through the 5V converter) but my panel is good for 0.4 amp or more so the rest of the power is not used if I'm not using a big smart phone. With a power bank it will draw more current but the small phone will keep charging even if the sun goes in.

any particular reason why using a 12v extension then pluging in single adaptor rather than just connecting direct to the single adaptor

Can i use a 100w panel directly to the 12v socket? Tnx

Using this system for 12v car battery portable super heavy kit 5 or 6 years ago.. Heavy but long lasting..lol.. Its just same, only different source but still 12v.🤣🤣

I like learning from you. I’m gonna try to bring some dead 18650 batteries back to life - thanks to you. Subbed 👩🏾👍🏾

what if you used a buck converter hooked up to a solar panel?

Thank you again for your cutting plastics vid. You saved my project.

Tnx sir I'm glad I find a video where I can used a different solar panel in 1 USB converter.

Very clever. Might try this myself

people need to get rid of those bulky AC adapter, you clearly see the power loss upwards of 4Watts!

end battery hunger!

Great work! Very creative and helpful video. Thanks for posting.

You can charge electric cars with solar panel via USB charging ports. I've tried with regular gas cars; after charging the battery, my windows moved much faster meaning it did charged the battery. Only concern I have is over charging. There should be a controller to prevent the over charging the battery.

yeah i want the batteries, the timer, and the panel though

This is great! Those cheap 5v usb plugs SAFELY regulate 20v without a charge controller or battery? Is there any way to do this SAFELY with a 200 Watt 20v solar single panels to charge and run several things with 5v 2.4a? What happens if we get perfect solar and get the full 200 Watts from the panel? I want to mount a specific flexible solar panel physical size (32 wide x 42 long) on my van.. in part because I want to benefit from the shade on my van roof. The biggest wattage I have found is 200W 20v single panel. I am testing a Chafon 200WH (18ah) portable power station that has a built in charge controller .. I tested it with a 50w panel and it fully charged in about 6 hours. The back of the unit has a warning not to use a solar panel larger than 120w and/or 22v. Given that most panels don't yield what they say would this be safe to direct connect? Also, if my real goal is run a fan in the van during direct sun light, anyway to regulate the 200w/20v panel so I don't need much battery but also so I don't burn my fan motor? Odd idea, but if too much power for the Chafon.. can I just cover part of the panel? My gut feeling is that connecting the 200W solar panel direct to the Chafon will be fine.. and that the 200W solar panel will never perform that well to be a problem.

Sir please tall me that solar how watt

The voltage is not stable

I have a challenging task to ask if you could perhaps try and show us how to make solar power blinds I just saw solar gaps asking over £100.000 grand for them way too much if u ask me

Connecting the same way the fluctuating panel voltage have usb 5v voltage fluctuation of 0.15v & it that okay compared to car use of 0.01v fluctuation.

What is the name of the board

By the way love your work

thank you so much for the great experiments with this panel and chargers ..I'm trying some of my own and I just burnt up my board on my 21w portable panel.i don't know how but it's fried .so it looks like I'll have to try and get a USB charger on it like you did..thank you and it's much appreciated..bless.

Hi i have solar system on our Toyota Coaster Camper bus. And there are 2 set of double USB ports in the bus. One set at the head of the bed and another set at the bottom of the bed. Just wanted to know how I can change The solar USB ports at the head of the bed to electric. As our solar system is not set up yet. 😃😃 I want to keep one set as solar and the other one as an electric one. So we have the choice of either electric or solar to charge our phones extra 😃😃

Can a 9Volts, 2.0A Solar panel work with one of those usb car charger ? I Was wishing you would test your 6v solar panel with one of those usb car charger.

Great video, thanks! I was wondering if I can charge a 5 volt battery directly plugged into on of those cheap pwm charge controllers that have usb ports without a 12 volt battery to anchor the controller. I watched your video learned a few new things and had the time to think about the pwm charge controller. I realized I only have to plug in my 5 volt battery and see if it lights up the screen on the charge controller. I think I like your other two methods better tho, anyway.

love that 12V / 10W - 20VOC Solar Panel, 12V cigarrette socket hack. i Like, OLE!

So you dont use any diodes at all?

Can that board be connected to 100 watt solar panel and will it harm to mobile/power bank...

no more boards on Ebay sad

Very nice

is this possible with an 80w 17v solar panel, would it be safe etc?

Your outstanding 👏 thank u very much for this video

Car chargers with USB ports are simply dc-dc buck converters

I would do something for strain relief.. maybe tie a knot in the power input wires before running them through the hole in the case.

Yeah that’s it I see it that’s it all you need is a solar panel that’s it that’s all you need just a solar panel then what the hell is all that other crap around it come on dude

I got a request can you make a video how to charge drill battery when you loose charger or can't or isnt available anymore

This is awesome! What is the recommended mA range for smart phones?

So your phone support only 1amp current.

How do you show that page at 3:42? Thanks!

Thanks for all your videos , very informative and helpful ,.. I dont know a lot about electronics ,.. Can you please tell me if im charging a 20v powertool battery with this device does the battery automatically know when it is fully charged ? Is it as simple as solar panel to usb 20v - 5v and then to battery ? Sorry for my lack of knowledge .

C l e a R consice video full of information 👍🇬🇧

Good video my dear fellow

Awesome tests great info!

To connect to those input holes in the chip, how thick the wire must be? How many awg?

I have the green version of that charge controller. Sadly, I cant seem to get it to work due to my batterys low low current, tbh i think its dead.

OR you could just get a 5 Volt panel to start with.

This is awesome

Where can I get that little board, please tell Thank

Thanks for the content )

Would you please give us a link to the app you're using I would really appreciate it thank you I can't seem to find it

Well done. Been thinking to do my own tests on those cheap USB chargers as I have a 18v 0.6A 10w military amorphous folding solar panel that still works after being shot with a few rounds of 7.62mm bullets 😬. I want to be able to charge a 12v and a lithium ion power bank at 5v. Now I know the charging currents possible thanks to your video. Thank you sir! Saved me a lot of time.

Thank you for your video A question I have is could I use a solar panel to power like this setup for a wyze v3 camera that is 5v 1amp dc and night vision is 2-4 watts. The camera does not have a internal battery source only dc or USB. Thank you

hi vuaeco just sent a video of a food mixer I want test if motor ok as stopped working was from charity shop but its a good make its heavy glass so maybe can change switch or add my own so how do I bypass switch or the keypad thing on top and test motor.thanks.steve in uk

Very helpful

Have you a link for that USB power Board Module ?

Could you provide a link to that USB power board module?

A lot of cheap charge controllers come with USB ports, usually 5V x 2.4A. So can't you just get a $15 charge controller and use that to charge your phone? Seems easier.

Thanks for responding, I like your videos a lot. You explain things very well.

What app are you using on your phone to measure current?
