Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. Charging cables provide power connections, but not data. In a charge-only cable, the data wires are shorted at the device end, otherwise, the device may reject the charger as unsuitable.
Separate clutter into piles which you want to keep (Love it) or get rid of (Lose it). Complete tasks in which you have to reduce the Lose It pile, e.g. selling at a market, holding a yard sale or using a computer to hold an internet auction. Put what you weren't able to get rid of into another two piles – one to be recycled and one to donate
Quick Charge requires both the power supply and the device being charged to support it, otherwise charging falls back to the standard USB ten watts. Quick Charge 2.0 introduced an optional feature called Dual Charge (initially called Parallel Charging), [4] using two PMICs to split the power into 2 streams to reduce phone temperature. [5]
The legacy USB Type-A plug. This is one of many legacy types of USB connector. The design is intended to make it difficult to insert a USB plug into its receptacle incorrectly. The USB specification requires that the cable plug and receptacle be marked so the user can recognize the proper orientation. [34] The USB-C plug however is reversible.
USB On-The-Go (USB OTG or just OTG) is a specification first used in late 2001 that allows USB devices, such as tablets or smartphones, to also act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mice or keyboards, to be attached to them. Use of USB OTG allows devices to switch back and forth between the roles ...
5. Abandon ship. If all else fails and you’re still receiving enough spam emails to render your inbox impossible to use, it may be time to switch over to an entirely new account.
The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an ...
The device typically contains several capacitors and charge and discharge circuitry. When the device is connected to a USB port, the capacitors are charged from the USB port's 5 volt supply. When they are fully charged, the device discharges them through step-up circuitry, which delivers a high voltage back into the USB port.
