USB DIGITAL TESTER!!! SEE HOW IT WORKS!!!! 

just remember, if you dont have any wierd friends it is prolly you

Great introduction on what it does and the practical use for testing bad power bricks and cables. Thanks for showing examples.

Unlike a type A port, a type C port will not supply voltage unless a type C device has been connected, as part of its protection protocol to prevent plugging two power sources into each other. That's why the tester doesn't power up from the type C port until a device is also plugged into the tester and they negotiate the power up. The little accessory is a USB OTG adapter. It can be pushed into the type A input connector and then plugged into a phone, etc. that has a microUSB connector with OTG support. In this case the phone provides the power (no other power source should be connected to the tester at the same time). A device like a memory stick can then be plugged into the tester and the phone will power it through the tester.

Your zap scared the shit out of me. Lol, good video buddy.

I bought the tester a few days ago, but wasn't exactly sure how to use it. I'm still a bit foggy on it, but your video has helped.

Pretty neat thing great way to test those USB to find out what’s going on. 👍

Using this I verified a usb-c port didn’t work so it was well worth the money. I think everyone needs one.

Great video on how to use this. I kept plugging mine in expecting it to work like a receptacle tester and when it didn’t come on I figured it was broken. Didn’t know I needed a source to be charged to see it turn on.

That's a neat little doodad, I just ordered it, thanks for the video.

lol nice Intro!😂

I got mine for $8 from aliexpress it’s still on there. Same model as the one in this video. Iv had it for almost 2 years now still works great.

Where did it go... There it is!! 😁.. I bet I can use it as a component tester... 😳... It got a limited load range though... 😁

Charley brown is a good show. I think the type c has a weird open to close circuit thing where it only works if you have power going on and going out. That zap effect made me jump that was funny. I can probably use something like that to test many devices cables power packs and battery packs. It can come in handy I wish everyone best of luck on trying to win the product

Nice presentation. Thanks.

The reason that the tester doesn't appear to be working when you plug it into the Type C is that you're missing the dongle for the Micro USB input - that should have come with the device and needs to be inserted in order to use the device on a Type C USB.

Anyone know of a more comprehensive video explanation? Clicking the display button cycles through some interesting screens, 2 of which are graphs and I'm looking for info on what they read and example use cases. Also on the bottom right of your LCD display is "OFF" ... On mine its a red "NO. 01". Curious what model does it say on the back? I ordered same one with bluetooth and it didnt have the VA/D+- graphs

neat

great thanks!

If we're testing the charging speed of our phone, should we look at voltage, amp, or total power if we're just looking at 1?

Good video. But for the love of God, peel those protective clear plastic membranes off the unit; they look like shite. :)

End game... 😳

LOL at the intro

$25 on Amazon, living in Thailand has its advantages direct market from China same device cost me under $12

3:17 not funny

cani still win

I found the formula for wattage.

I bought a new cell phone. I found this to be (normal) but not always the case. My new cell phone is capable of charging up to 15 watts but comes with a 10-watt charger. I have chargers I have accumulated over time. I am old and my eyesight is not what it used to be. I can't read the extremely small print even with my reading glasses that are printed on the brick. I just want to know how many watts my bricks are putting out. I may already have an older charger with 15 watts or better so I ordered a new charger. Possibly, I may have already had one to do the job Will this device tell me the wattage?

Can you use this device in both directions? I want to measure Raspberry Pi 4 power supply, which is USB-C Male on charger and USB-C Female on Raspberry Pi. So that would be like this: Power supply USB-C Male end goes into this device USB-C Female Output port and USB-C Male Input goes into Raspberry Pi. Can you test this if it works in both directions or do I need additional adapters too.

Damn near left the video with that intro

Question? Is there a way that you can store the data streaming from the USB digital tester into your laptop?

I'm doing nuttin

I didnt get the alligator clips or a plastic over mine

How to use the Bluetooth 0:00

Are you still giving one away??

Do he know the difference between voltage and current ? 😉

Faltou legenda ou tradutor

That device is crap :/

You also can use a simple USB gadget: www.ramser-elektro.at/lil-usb-tester-usb-schnittstelle-schnell-getestet/
