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

Can you power a USB port by just a solar panel without a battery? Let's find out. I'll also show you another (easier and better way) to do it by using a 20V to 5V regulator.
Here's the link for the ebay search for the solar regulator. There are 3 versions of this board where 3 different capacitors are used: Electrolytic, Solid, and Ceramic. If you use it a lot, I'd recommend using ones with solid or ceramic capacitors.

The apps I use to measure current on my phone are "Charger Tester" and "Ampere Meter Pro". These are for Android OS only.

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

[@mesourimamalindas1261]

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

[@davidb2206]

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

[@Pushyhog]

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

[@epprodigital3262]

Very clever. Might try this myself

[@guitarman_3693]

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..

[@UltraRik]

Awesome tests great info!

[@mustangandfrankenstein]

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.

[@stevenlegender5538]

By the way love your work

[@girl600podcast]

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

[@Nikitafrom233]

Thanks for the content )

[@Sahel_prince]

Good video my dear fellow

[@100roberthenry]

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.....

[@superwag634]

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.

[@fvrrljr]

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

[@nasiruddin2045]

[@Earthmadegarden]

This is awesome

[@rajeshsonule798]

Very nice

[@mikejf4377]

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

[@leviahamefula3994]

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 ☺ 👍

[@Brizo1805]

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

[@MrGunningpeter]

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 .

[@OWK000]

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.

[@TimpBizkit]

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.

[@moonolyth]

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.❤

[@olgabozic153]

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

[@zeez3139]

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

[@stampgalore]

Where can I get that little board, please tell Thank

[@chidilamberto3353]

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

[@stormycanz]

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

[@lowellmd202]

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

[@elliotness6560]

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

[@oben9514]

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.

[@tohopes]

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.

[@alexc8992]

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.

[@craighare3799]

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

[@naturevideos1311]

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

[@pyongyangofficial5555]

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

[@12vLife]

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.

[@trevercole4644]

So you dont use any diodes at all?

[@stevenlegender5538]

What is the name of the board

[@DesertVox]

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

[@codechanged]

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

[@willappleton]

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

[@Mefisto0901]

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

[@steveg6600]

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

[@jessejensen3147]

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

[@vuaeco]

The app with big round circle is called "Charger Tester". The other app with small/little letters is called "Ampere Meter Pro". My phone runs on Android OS. If you have an iPhone, it would be different or might not be available for other OS.

[@ourcampingadventureothervl9661]

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 😃😃

[@ashnilasishram6883]

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.

[@Sahel_prince]

Sir please tall me that solar how watt

[@choikyow]

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.

[@Edmorbus]

Have you a link for that USB power Board Module ?

[@vuaeco]

I've added the search link to the description above.

Thanks for the link

[@tabineshhtc]

So your phone support only 1amp current.

[@mukeshpandya4171]

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

[@stevemcgowan3017]

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

[@vuaeco]

It depends if the motor is AC or DC. The motor of the mixer I had was a DC motor so I was able to use my power tool battery to test it. The power plug was AC but inside it has a AC to DC regulator to run the DC motor. You will have to disassemble it first to check and see if the motor is AC or DC. Some AC motors are even OK to run on DC. They are called universal motors, I think.

[@stevemcgowan3017]

ive got the mixer working now maybe it was just reset switch .thanks.i need to build a 12v supply so can power a car satnav on my electric bike how would you do that?maybe 4 cells but that's 14v bit too high perhaps voltage regulator?

[@cowhand1206]

no more boards on Ebay sad

[@TRYtoHELPyou]

[@vuaeco]

Yes, indeed.

[@musicrock_]

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.🤣🤣

[@babelfishdude]

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

[@daleval2182]

The voltage is not stable

[@ianendangan7462]

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

[@QuantumBraced]

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.

[@tucuquitodelalma]

I know that I'm very late to this comment but here I go: Yes, a cheap charge controller would be better at charging a phone but to work they need to detect a load(battery), that's the method he showed at the start. The way he showed here is a method that doesn't require a battery.

[@gkeith4120]

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
