Quick Charge is supported by devices such as mobile phones which run on Qualcomm SoCs, and by some chargers; both device and charger must support QC, otherwise, QC charging is not attained. It charges batteries in devices faster than standard USB allows by increasing the output voltage supplied by the USB charger while adopting techniques to prevent battery damage caused by uncontrolled fast charging and regulating the incoming voltage internally.

They act by transferring the forces via mechanical interlock. This fastening technology is used in steel-to-steel connections, for instance, to connect cold-formed profiles. A screw is inserted into the base material via a gas-actuated gas gun. The driving energy is usually provided by firing a combustible propellant in powder form. The fastener's insertion provokes the plastic deformation of the base material which accommodates the fastener's head where the force transfer takes place.

A high-tech solution to a low-tech problem has emerged. Oral irrigator, water pick, water flosser, air flosser. It goes by many names, but it is more or less the same. An oral irrigator is a device with a small nozzle that will shoot water, air, or a combination of both at your teeth and gum line in order to remove plaque and food debris. A 2009 study showed that oral irrigators are very good at removing plaque biofilm from teeth, so there seems to be a compelling argument for getting one. Let's take a closer look at the pros and cons.

A socket tester ;is a portable electrical instrument used to test for correct operation and wiring standards on power outlet sockets. It is typically a hand-held instrument that either plugs directly into the socket with pins mounted on the tester or come equipped with a short lead and plug. Depending on the sophistication of the socket tester, a range of status indications may be returned including disconnected phases, reversed phases, and, in the case of a top-end instrument, earth loop impedance.
