Juice jacking is a theoretical type of compromise of devices like smartphones and tablets which use the same cable for charging and data transfer, typically a USB cable. The goal of the attack is to either install malware on the device, or to surreptitiously copy potentially sensitive data. [ 1 ]
The Apple Battery Charger is a battery charger which was sold by Apple Inc. and bundled with six AA batteries. It was introduced in July 2010 and marketed as a way to charge Apple's wireless Magic Mouse , Magic Trackpad and Apple Wireless Keyboard . [ 2 ]
Inductive charging pad for a smartphone as an example of near-field wireless transfer. When the phone is set on the pad, a coil in the pad creates a magnetic field [1] which induces a current in another coil, in the phone, charging its battery. Generic block diagram of a wireless power system
The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
Inductive chargers produce more waste heat than wired chargers, which may negatively impact battery longevity. [14] [better source needed] An amateur 2020 analysis of energy use conducted with a Pixel 4 found that a wired charge from 0 to 100 percent consumed 14.26 Wh , while a wireless charging stand used 19.8 Wh, an increase of 39%.
Inductive battery chargers use electromagnetic induction to charge batteries. A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery.
ELF waves around 50 Hz to 60 Hz are emitted by power generators, transmission lines and distribution lines, power cables, and electric appliances. Typical household exposure to ELF waves ranges in intensity from 5 V/m for a light bulb to 180 V/m for a stereo, measured at 30 centimetres (12 in) and using 240V power.
Amazon Alexa, or, Alexa, [2] is a virtual assistant technology largely based on a Polish speech synthesizer named Ivona, bought by Amazon in 2013. [3] [4] It was first used in the Amazon Echo smart speaker and the Amazon Echo Dot, Echo Studio and Amazon Tap speakers developed by Amazon Lab126.
