**The Curious Case of the USB Killer**

As a curiosity-driven individual, I decided to put my trusty USB killer device to the test on various smartphones and tablets. The goal was to see if this device could actually kill or disable these devices using high current. In this article, I'll take you through my experiments with different devices, including iPhones, Samsung phones, and a few others.

**The iPhone 7 Plus Dummy**

First up, I had the opportunity to test the USB killer on an iPhone 7 plus dummy phone. This was more of a precautionary measure, as I didn't actually want to harm any real iPhone. However, it was interesting to see how the device responded. After plugging in the safety tester, I noticed a tiny spark and some sound coming from the iPhone. While it wasn't getting much power through, it did seem like there was some energy present.

**The Death USB**

Next, I decided to put the USB killer to the test on the dummy phone again, but this time with a bit more force. After letting it sit for a couple of minutes, I plugged in the device and waited to see what would happen. To my surprise, I started getting a tiny spark, followed by some sound and even a little bit of vibration. It was clear that the iPhone 7 plus dummy phone was being affected.

**The Moment of Truth**

With caution, I decided to plug in the real iPhone 7 Plus into the USB killer. The device responded with a faint click, which seemed to indicate that it had indeed done something. However, when I unplugged the safety tester and tried again, there was no response whatsoever. It appeared that the iPhone was not affected by the high current.

**The iPhone's Safeguard**

Further investigation revealed that the iPhone has an internal safeguard against this type of attack. When plugged into a non-compatible device like the USB killer, the iPhone refused to respond or charge. This made sense, as it would prevent someone from trying to use these devices maliciously.

**The Galaxy Note 7**

Next up was the Samsung Galaxy Note 7, another popular smartphone that had been notorious for its explosive battery issues. I plugged in a special adapter to test the device and hold my breath, hoping that it wouldn't explode on me. To my surprise, the phone charged normally, despite the high current being pushed through it.

**The Unplugged Safety Test**

Before plugging the Galaxy Note 7 into the USB killer, I decided to do an unplugged safety test by unplugging it from the charger and trying again with just the adapter. Surprisingly, nothing happened – no sparks, no heating, no signs of distress. It was clear that Samsung had implemented a similar safeguard as Apple.

**The Charging Option**

After further investigation, I discovered that the Galaxy Note 7 has a built-in charging option that's meant to supply power directly from the device itself. Unfortunately, this means that even when plugged into a non-compatible device like the USB killer, the phone will still try to charge normally and ignore any attempts to short-circuit it.

**The Samsung Safety Precaution**

While I was able to get some sparks coming out of the Galaxy Note 7's lightning port, it didn't actually do anything significant. However, when I tried charging the device again using a regular charger, I realized that the lightning port itself had been compromised by the USB killer. This made me realize that Samsung has taken steps to prevent such attacks.

**The Real Test**

After all this experimentation, I decided to put the USB killer through its final test: on my personal iPhone 7 Plus. The device responded with a loud click and some sparks, but after unplugging it again, I realized that it was still functional – albeit without charging. While it did seem like the lightning port had been damaged, the rest of the device remained intact.

**The Final Conclusion**

Throughout this experiment, I learned that both Apple and Samsung have implemented safeguards to prevent malicious attacks on their devices using high current. While the USB killer is designed to be a powerful tool for short-circuiting devices, it's clear that these companies are taking steps to protect their users from potential harm.

**The Verdict**

In conclusion, while the USB killer device did seem to affect some smartphones in certain ways, its impact was largely limited by built-in safeguards. I hope this experiment has provided a useful insight into the world of USB testing and the measures that companies take to protect their devices.

"WEBVTTKind: captionsLanguage: enwhat's up guys everything Apple Pro here and most of you don't know what this is this is pure Tech death in my hands this is called a USB killer version 2.0 so it's one sole purpose is to destroy anything you plug it into as long as it has power so I just want to show you guys in this video what would happen if I were to plug this into an iPhone 7 plus this is just pure curiosity I mean the first thing I thought of when I heard about this is about Mr Robot when they dropped the little USB on the road and a cop picked it up imagine you find a high enough storage USB you know I would pick it up if it was at least 64 gigs and you go to plug it into your computer and upon plugging it in upon impact boom it fries the motherboard the way this works is it's actually composed of about five capacitors that just attain charge very quickly upon plugging it in and they send out an extremely high voltage energy that goes ahead and Fries the motherboard or any components in that computer and if I can open this up real quick I just want to show you guys what's inside so there you go it's just pure capacitors and as long as you have a way to plug this into a device you can go ahead and Fry the internals so let me just show you guys as a proof of concept what happens if you plug it into a computer real quick so I'm going plug it in here and careful not to shock myself this is actually the tester unit so it's basically preventing the charge from going going to the computer so I'm going to plug it into here and I'm going to zoom this in so you guys can see what's going on here but basically as long as you have power on the device you're going to be able to see some Sparks man this is some powerful stuff for real so before we go to the iPhone we're going to go ahead and plug this into my old computer this is something I started the YouTube channel with I was making my very first YouTube videos on this computer so it's really like a trip down memory link today uh this thing is amazing I built it myself at age 14 which is nothing special but you know it served me well but it's taking up space it's dying so it's time to get rid of it and what better way to do it then with a super high-tech USB killer I'm going to plug in the Death Stick and let's see what kind of charge we got here should be a very very good amount oh yeah that's strong all right so performing the test unplugging from the safety tester and here we go so I'm gonna go ahead and find this USB port goodbye sweet prince it was a good run 3 2 1 oh you heard that it was like a crackle and I'm going to unplug it that took like a little bit longer than I thought I thought it'd be instant but about a second and a half and try and plug it in and I'm going to try and power it on no luck it is completely dead just like that so I'm not entirely sure if it's in the power supply the motherboard or where but the computer is done like it just will not work that's it success so with the computer dead I've got a brand new iPhone 7 plus right here I just activated it plastic wrap is now off and uh yeah so I'm kind of curious what'll happen I think just the lightning Port will get fried there's no way that the iPhone 7 plus doesn't have a guard against High electrical currents so something will break before it enters into the logic board but with the tester let's see uh if we can get a some sort of response from this so I bought one of these that's a lightning to USB in order to import photos stuff like that so plugging this in I'm going to go ahead and plug in the tester first and then the death USB okay it's now working so I just had to let it sit for a couple minutes I guess it takes a little while for it to charge but I do get a little tiny spark in there and a little bit of sound so because it's such a low voltage Port you know you're not getting a lot of power through it it's not meant to Output power like on computers there is some energy before I do this though let's try out the iPhone 7 plus dummy let's put this thing out of its misery real quick so unplugging from the safety tester now this one I was never able to get any sort of current through here like no response I'm not sure why that is so pushing that out plugging in the killer USB into the iPhone 7 plus clone in 3 2 1 and and nothing surviving hm nothing at all so interesting okay so this thing isn't affected iPhone 7 plus here we go I'm going to unplug this first plugging in this guy now the interesting thing that I found is if your device is locked with a passcode I was unable to get any sort of spark so if you're worried about someone just plugging this randomly into your phone don't be nothing will happen the iPhone doesn't allow any input like that so here we go the Moment of Truth plugging the USB killer into the iPhone 7 plus in three two one and I heard a click so it definitely did do something no click this time could it be that the USB port itself just died oh it keeps clicking I guess I'm going to keep it plugged in here nothing is happening H still able to use my phone just fine so I'm going to set it aside for a couple minutes and see if anything happens to it listen to that it's making all these clicking noises like it keeps sending current through here but nothing is happening the iPhone must have a safeguard against this I thought so okay so couple minutes has passed I'm going to go ahead and unplug this and see if a regular charge still works here nope I'm unable to get any charge all right so iPhone 7 plus right here no Tom Foolery I'm going to go ahead and plug it into this USB Bank it is a Samsung don't hate but I'm getting no charging or anything like that so if I plug in my personal iPhone 7 plus I'll show you guys that it does charge it so there we go it is on and working as you guys can see it is charging if I plug this one in it appears the lightning Port is done for so yeah guys there it is that's the lightning connector I was UN able to kill this thing I'm going to plug it in once more in the back here it just fries the lightning connector unfortunately so I was hoping for a little bit more but I'm not done yet let's see what happens to the Galaxy Note 7 will this thing explode and I actually plugged it in through this adapter and man does this thing have a charge through it so let's try into the Galaxy Note 7 this contraption goes I mean look at this this is going to kill your device right here and just to show you guys this has a much stronger charge versus the iPhone it actually puts out a lot of Sparks so it's definitely there I don't know why my camera isn't picking it up very well it must be the frames but there's definitely like a lot of Sparks from the Galaxy Note 7 okay unplugging the safety part right here and here we go so into the Galaxy Note 7 in 3 2 1 and I'm going to report if I feel any heating up but I just don't want it to explode on me so far nothing it it actually says something with the battery up here oh no it's just discharging no heating up to report I'm going to unplug it and replug it in nothing so somebody actually posted a video about this killing uh Nokia just instantly but seems like Samsung and Apple both have some sort of prevention against this against High current I'm a little disappointed I really wanted one of these phones to die so the Galaxy thinks uh this is a USB right here so it wants to Supply Power charg the connected device via USB let's try the charging option right here so nothing unfortunately that was a bust the Galaxy Note 7 did not explode same power bank it does work after the USB killer all right so guys thanks for watching this video was just the true extent of my curiosity I really wanted to see what would happen and apparently it does affect your iPhone it doesn't completely kill it so might as well though it kill the lightning Port which is a costly replacement anyways guys be careful about what you plug into your computer or your phones hope you guys enjoyed this video fun little video I decided to make have a great day peacewhat's up guys everything Apple Pro here and most of you don't
