These can surely work for non-high-demanding electronics such as LED strips, a router, etc

power booster uses amps to amplify voltage, 5v 2a USB port will get less than than an amp boosting to 12v, for low demanding devices, it's great, better than using those bulky power supplies. You can even mod the system to implement a USB C port.
Using it for Degen DE1103 / Kaito KA1103 (LW/MW/SW/SSB/FM receiver) 8V or 9V to 5V USB adapter. It also use to charge that radio for 1 day or 14H using Panasonic NiMH 4AA batteries.
I had the 9V/12V digital one, and it burned up instead of shutting off. I was pulling about 1A at 12V, the input current was about 5V 4A. It switched down to 5V like you demonstrated, so I shut off the device that was connected to the output. However, the adapter was still plugged into the source drawing current. Therefore, there is a danger that too much power will cause runaway and burn up the transistors inside. I won't miss it, the other square unit with the white/blue label doesn't seem to have the same issue.
In order to boost the voltage.. more amps are drawn then what they actually draw. The boost converter draws a bit of current then add in what the device you are powering draws. The current draw could be too much for the usb source the power is drawing from
The cheap model's are not designed for hard core devices, just mainly small musical units like Korg, Behringer, 4 channel audio mixers etc. Anything less than 1A as that's the absolute limit of the chip.
Great video! Maybe try using usb female to 2 male and get more power from using twice the power using both usb ports from power bank:) 5v 2.1a =10.5w times 2 ports = 21w
Interesting video. Unfortunately the links aren't available anymore. It's difficult to find this kind of converter with high output. I would like to have some tips on where to find powerful converter.
I have a Jackery power station and a Line 6 Pod Go guitar pedal that requires 2.5A at 9V. It would be nice use a USB adapter like this and not a lossy inverter on the Jackery into a lossy power AC/DC supply. Some people have claimed that the Pod Go runs fine on 1A power supplies but I'm hesitant to run it on anything rated less than 2.5A
Is the adapter your using still holding up after long load times? Also do your top two picks produce any noticeable heat under load? I had ordered the same two adapters you liked the best and would like to know your experience with them. I'm planning to use mine to power a monitor that claims to require 12v 2a but can also be run at 9v it probably doesn't need the full amount of power it requests though I'm about to find out though haha
I have a question for anyone here to answer. Am I right in thinking if I have two devices to power from a single battery plate. 1 device draws 1.5 amps and the second device draws 3 amps i have a battery that can produce 5 amps. This battery will be OK? For your information the devices are a digital camera the battery for which requires 1.5 amps and a HDMI monitor screen which draws 3 amps. There are battery plates out their that do supply power to a monitor and a camera using this exact battery. The battery is a Sony NP-F series battery. These batteries are a very common battery in media industry. They are mostly 7.4 volts 5000mah. The monitor is 12 volt DC in with a barrel connector.
sir, i have a question...i have power bank output 5v..if i use step up from 5v to 19v, can i charge my laptop...i want to make power bank to charge the laptop......my laptop is inbuilt battery, use 19v adapter...aspire e11....what do you think?

As soon as you said "watt" instead of "volt", I tuned out.
Pretty goofy I agree

mine too has burned up so rapidly, it is still stucked at 4.8v... a magnificent garbage
Very helpful video. Unfortunately, the link to your top pick is dead and I can't seem to find it elsewhere. Any pointers appreciated. Thanks.

I am using my $3 ebay one with my yamaha reface cs, it works well.
Would you let me know the brand name & model number on 9:34. Thanks.
Great video! Maybe try using usb female to 2 male and get more power from using twice the power using both usb ports from power bank:) 5v 2.1a =10.5w times 2 ports = 21w
wonder if bigclive would wand to look at the broken one?
Interesting video. Unfortunately the links aren't available anymore. It's difficult to find this kind of converter with high output. I would like to have some tips on where to find powerful converter.
Where I can find the last one?
The way you say watt and volt, sometimes I can not understand what unit you mean.

You can try it anyway, less volts/Amps won't damage. More voltage than specified will.
"don't hang me up for that one"
As if the danishness wasn't already blatant :P
Where's your voltage tester
Great video, but your link does not work. Where can I find it? Does it have another name? Thanks for helping.
very useful informations!
Hi do you know if any of these are true dc to dc converters? Do any of them get hot?
Hey nice video thanks, exactly what I needed.
That you sir 👍

Fry anything
they will be stucked at 4.8v ...
Would really like to know where can purchase the last adapter tested. I need one that can output 12V 2A.
Do you have Power Delivery USB protocol in your powerbank?
Now you need to find a 5-volt power bank you want to haul with you. You need to do more math.
Bro the last usb step link to buy is not working.
I love your accent 😅
Should I have to buy the blue thing also?
no lol

12V 2A LINK?
Hello sir is any way to prevent switching effect delay in powerbank while using this adapter with charger connected to powerbank?
Great Video!!!
Danglish lvl max. But tak very meget anyway 👍🏼
Det bemærkede jeg også :D - Men alt var klart og forståeligt
@@Hardts ja, intet dér! 😄
Need to power a 9V 0.8A device... what happens if I plug it in and the adapter is set on 12V by mistake?
Your 9v device would likely explode due to over voltage..
Cant find nr5. Please help me.
Where can i buy the last one?
Link is broken
Ok thanks brother👍
Is there a polarity in that converter? I am planning it to use on my guitar effects which uses center negative polarity.
Try aliexpress and/or ebay, surely you should be able to find a converter there.
sir, i have a question...i have power bank output 5v..if i use step up from 5v to 19v, can i charge my laptop...i want to make power bank to charge the laptop......my laptop is inbuilt battery, use 19v adapter...aspire e11....what do you think?
Its not only the v that you need to regulate but the Amp too. (A)*(V)=(W)
Tldr; no.
5v to 19v , you will definitely be utilizing a frying fan to cook something from it.
It would probably give you more credibility to stop saying watt when you clearly mean volt
That's just his accent...
Germans say a V as a W sound.
He's saying volt every time.
Can I use 2 of these on 1 20Ah power bank? Output requirement is 1mah and 0.5mah with 12V.
Yes you can definitely do that it will work on pretty much any power bank so yes
@@alexandergilbert6490 i want to buy like this adapter to charge my laptop
it requires 19.5v 11.5A
Can i find something work with the power bank?
Hay Arnold Schwarzenegger got a new channel !! Lol
Links are mostly broken :/
Can this run 50watts?
would it able to load a Laptop with it?
No
We can't find out sl.5 convertor. Where are you buyed
this converter seems to not be available anymore nowhere. A shame, it was the only good one of the video ...
@@Tetsujinfr Unfortunately, i need it. Can you recommend alternatives? Thanks
Dude they need to make one that puts out 19.2v my laptop would have infinite charge 😂
Those exist too
you sound like arnold schwartzeneger lol
you sound a bit lacking in culture
@@thomasgarguilo3745 dont act like a white colonizer exporting civilization to those "barbaric natives"
har du linket til den sidste af dem ???
looks like i cant replace my 12v 3A charging unit with that lol
you keep saying 12 watts....do you mean 12 volts. you are very confusing
i guess better use a real adaptor when possible dont wanna stress my hub with something like this
They can be made for cheaper lol. Make em your self
...does it work reversed...?...12v to 5v
No
DC only flows one way.
