A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.
An active laptop cooler. A laptop/notebook cooler, cooling pad, cooler pad or chill mat is an accessory for laptop computers intended to reduce their operating temperature when the laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both the laptop from overheating and the user from suffering heat related ...
A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [7] Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.
The price is half that of an "iPad, even less than an iPad Mini or an iPod Touch. And you’re getting a laptop." He wrote that the Chromebook does many of the things people use computers and laptops for: playing flash videos, and opening Microsoft Office documents. "In other words, Google is correct when it asserts that the Chromebook is ...
In most cases, it can charge the battery and power the laptop simultaneously. When the battery is fully charged, the laptop continues to run on power supplied by the external power supply, avoiding battery use. If the used power supply is not strong enough to power computing components and charge the battery simultaneously, the battery may ...
Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which run on Qualcomm system-on-chip (SoCs), and by some chargers; both device and ...
