USB Killer v2.0 can kill a computer in seconds

USB Killer Version 2.0

Here in USBFlashDrive64GB blog, I will not just share to you the latest and coolest USB flash drives available, but also the pros and cons, new technologies used, and even the harmful usage of USB devices such as this dangerous device called USB Killer v2.0, created by a security researcher code named “Dark Purple”, which is designed to destroy a computer.  This USB stick is the successor or much improved version of the first version announced last March which is also capable of destroying sensitive components of a computer when plugged-in.

How does USB Killer works?

The USB Killer v2.0 is a flash drive created by a mad genius YouTube user “Dark Purple” that aims to end a computer life when it is plug in, as it delivers a 220-volts of electric surge repeatedly back and forth from the device to your computer until your computer die. This is made possible  because of the DC to DC converter equipped inside the flash drive, which is responsible of charging a set of capacitors.

The v1.0 of the USB killer is consist of a few caps, FET and DC to DC converter as well, although it can only transfer electric current of -110 volts which is now doubled on the newer version. Another major improvement in the USB Killer version 2.0 is the activate time. Once plugged into a computer, either a laptop or a desktop, the USB Killer takes only a few seconds for it to kill a PC, shutting it down completely.

As far as I know, a USB device should run at least 5V of power to operate and function as it normally do, so imagine of returning a whooping 220 volts to your competer repeatedly until your system shut off completely destroying every peripherals inside, that is indeed a smart invention but a harmful one.

Is it Harmful, Definitely Yes!

Imagine if this kind of device is replicated and distributed worldwide? In my own opinion the damage it can do is 100 times disastrous that a normal virus can do, because for viruses it will just corrupt your files, or worse case scenario hackers can still your important financial accounts and that is indeed a major problem, but if you are a typical computer user it is not much trouble.

The USB killer on the other hand will completely destroy your computer, what if computer newbies get their hands on this device and plug in on their newly bought computer. I know you will understand how they will feel after the damage this device can do.

To learn more about this USB device, you can watch the following videos for more information.

The basic idea of the USB drive is quite simple. When we connect it up to the USB port, an inverting DC/DC converter runs and charges capacitors to -110V. When the voltage is reached, the DC/DC is switched off.

At the same time, the filed transistor opens. It is used to apply the -110V to signal lines of the USB interface. When the voltage on capacitors increases to -7V, the transistor closes and the DC/DC starts.

The loop runs till everything possible is broken down. Those familiar with the electronics have already guessed why we use negative voltage here.

I’ll explain to others that negative voltage is easier to commutate, as we need the N-channel field resistor, which, unlike the P-channel one, can have larger current for the same dimensions.

Leef iBridge Flash Drive for iOS Devices


For today’s featured USB product, I would like to introduce to you the Leef iBridge dual-interface flash drive. This specific thumb drive is unique in a way that is fully compatible with Apple devices that comes with a lightning port such as iPhone 5, iPhone 6, iPod Touch 5th gen, iPad Mini, iPod Nano 7th gen, Apple Pencil and iPad 4th generation onwards.

If you owned one of these devices, I’m very sure you are aware that iOS devices are limited in terms of memory, so there are only 3 options for you to solve this low memory issue. First is to delete some of your files stored in your device, but still I can say time will come that you need to select and delete the files that are even important to you. Second option is to upgrade your device in a way that you will buy a similar phone with larger space, of course instead of buying the similar phone why just buy the latest released Apple devices if money is not an issue. Last option is – you have to buy a flash drive such as the Leef iBridge to increase your iOS device memory externally up to 256GB.

As of this point of writing there are already new flash drives available in the market with the same function as Leef iBridge such as the popular SanDisk iXpand Lightning Flash Drive, Hyper iStick, Aizbo I-Flash drive with microSD card, just to mention a few.

Leef-iBridge-iPad-MiniThe iBridge USB device has a unique design, which looks like an umbrella handle to me because of its J-shaped where the other end has a standard USB 2.0 port and a lightning interface at the other end for your Apple gadgets. Some described the USB to have a wrap-around design as it literally wrap the smartphone either way. I also want to point that even if you are using a protective casing for your device, there is still an ample amount of clearance space for the iBridge, cool right?

Once the lightning flash drive is connected to your Apple gadget, its companion iOS app will launch with intuitive interface for you to manage the disk with ease. You will see options such as transfer files either from your device going to the flash drive or vice versa, although it only allows transferring of videos, music, photos and documents so every downloaded games and apps can’t be save.

There is also an option called content viewer, meaning you can directly stream any music or video files to the drive, without the need to transfer it your iOS device. Imagine you are watching a 20-part Full HD TV episodes on your iPhone 6 plus and you need to erase 2-3 episodes before you can transfer the next 3 episodes, such hassle right? By using the iOS flash drive, you can simply store all the TV episodes on the flash drive and stream it to your iPhone directly.

Last option is labeled as iBridge camera, where it can be set as default storage for the photos taken by the camera.

The iBridge Lightning flash drive will be available in different storage options and pricing starting from $60 for the 16GB, $80 for the 32GB, $120 for the 64GB flash drive, $200 for the 128GB variant and an expensive $400 for the 256GB.

My last words for you, aside from the three options that I gave you above, if you really want to save yourself from headache because of low memory, I suggest – the next time you buy an iPhone or iPad or any Apple product, go with the largest capacity so that you will not worry too much on the disk usage while using your beloved device. This reminder is also applicable for folks who buy Android devices, as there are premium android smartphones nowadays that does not have microSD card slot, but only built-in internal memory so always read the full specification of the device that you are going to buy.

Other World Computing: Envoy Pro Mini SSD Flash Drive


I’m sure you are aware how fast solid state drives are compared to a standard hard drive, what more a mere USB flash drive if we are going to compare them with SSDs, for sure you already know the winner. What is my point? My point is what if there is a flash drive that disguise as an SSD? Well that sounds crazy isn’t it, but actually there is a gadget that exists, and it’s called Envoy Pro Mini from OWC Company.

Other World Computing’s Envoy Pro mini is a USB 3.0 thumb drive available in 120GB and 240GB storage capacities, equipped with pocket-sized SuperSpeed SSD’s that’s why it can perform twice as fast as typical flash drive. The thumb drive is relatively small, as it measures only 3.7 x 0.94 x 0.44 inches, and it comes with a 14-inches USB 3.0 interface cable. According to the information I’ve found, the budget-friendly Envoy Pro mini USB device can sustained a transfer speed up to 433 MB/sec and it is currently priced at $119 for the 120GB and $199 for the 240GB.

Lastly in terms of aesthetics, this flash drive looks really dull, but I can say that looks are really deceiving and if we are going to measure this thumb drive ratings, I’m very sure that you will be amaze on it,  in terms of performance. You can also see the how the company prioritized the security of your files as the drive itself was encased with an aluminum chassis with a detachable black lanyard for added safety against fall.
