Smart LED display, The 2 slot charger will charge the lithium batteries when plug in,and the indicator light display in red, then turn into green after fully charged.
We all have many different chargers lying jniversal the house. Often, we forget which charger was compatible with which device. Recently, USB-C chargers are becoming increasingly widespread across multiple devices, both smartphones and laptops.
Thus, most people are starting to wonder the following: is it actually safe to use a USB-C laptop charger to charge a phone? Here at Charger Universe, we wanted tk clarify the answer to this important question by sharing as much information as possible. Here we go. With the recent increase in popularity of certain standards USB-C and USB-PDthe short answer is increasingly becoming the following: in general, yes, it is safe to plug your laptop charger into your phone.
Read on for the complete details. These are having a common physical conection and using the same charging protocol. Fully reversible, the USB-C would be small enough to fit in smartphones, but robust enough universal charger how to use power laptops.
Fast forward tothe USB-C has become the new stadard in all sorts of devices. Apple has how to put picture in forum including it in their Macbook Pro since their model. But having a USB-C connector does not automatically make everything compatible with everything. The USB-C connector is simply the physical interface that gets plugged in to the device.
In order to have a successful charge, the devices must also have a compatible charging protocol. It is also the protocol behind the fast charging technologies recently deployed by Apple and Google, in their iPhone and Pixel phones, respectively. Nowadays, all modern batteries have a built-in charge controller that regulates the input voltage and prevents overcharging.
This works in conjunction with the fact that most chargers also support different levels of what can you do with forensic science degree voltage. The charger then suplies that power at the agreed voltage and current.
There is, however, a catch here. It is unlikely that you will ever encounter one, particularly now that retailers such as Amazon have completely banned them from their platforms. However, it is still relevant to stress the importance of using a genuine charger, above all.
Hkw laptops use a different and often propietary physical connector different from USB-C. There is nothing wrong with this approach.
However, as ofthere is no other connector widely being used to power laptops and also smartphones. This means that, even if you wanted, you would not be able to plug your laptop charger into your phone, simply because it would not fit!

Other common names include plug pack , plug-in adapter , adapter block , domestic mains adapter , line power adapter , wall wart , power brick , and power adapter.
Adapters for battery-powered equipment may be described as chargers or rechargers see also battery charger. AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply.
External power supplies are used both with equipment with no other source of power and with battery -powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment. Use of an external power supply allows portability of equipment powered either by mains or battery without the added bulk of internal power components, and makes it unnecessary to produce equipment for use only with a specified power source; the same device can be powered from VAC or VAC mains, vehicle or aircraft battery by using a different adapter.
Another advantage of these designs can be increased safety; since the hazardous or volt mains power is transformed to a lower, safer voltage at the wall outlet and the appliance that is handled by the user is powered by this lower voltage. Size and weight of the device was largely determined by the transformer, which in turn was determined by the power output and mains frequency. Ratings over a few watts made the devices too large and heavy to be physically supported by a wall outlet.
The output voltage of these adapters varied with load; for equipment requiring a more stable voltage, linear voltage regulator circuitry was added. Losses in the transformer and the linear regulator were considerable; efficiency was relatively low, and significant power dissipated as heat even when not driving a load. Early in the twenty-first century, switched-mode power supplies SMPSs became almost ubiquitous for this purpose.
Mains voltage is rectified to a high direct voltage driving a switching circuit, which contains a transformer operating at a high frequency and outputs direct current at the desired voltage. The high-frequency ripple is more easily filtered out than mains-frequency. The high frequency allows the transformer to be small, which reduces its losses; and the switching regulator can be much more efficient than a linear regulator.
The result is a much more efficient, smaller, and lighter device. Safety is ensured, as in the older linear circuit, because a transformer still provides galvanic isolation.
A linear circuit must be designed for a specific, narrow range of input voltages e. However, unless very carefully designed and using suitable components, switching adapters are more likely to fail than the older type, due in part to complex circuitry and the use of semiconductors.
Unless designed well, these adapters may be easily damaged by overloads, even transient ones, which can come from lightning , brief mains overvoltage sometimes caused by an incandescent light on the same power circuit failing , component degradation, etc.
A very common mode of failure is due to the use of electrolytic capacitors whose equivalent series resistance ESR increases with age; switching regulators are very sensitive to high ESR the older linear circuit also used electrolytic capacitors, but the effect of degradation is much less dramatic.
Well-designed circuits pay attention to the ESR, ripple current rating, pulse operation, and temperature rating of capacitors. The nature of these high speed, high-energy switching designs is such that when these preventative measures are not implemented, relatively high energy harmonics can be generated, and radiated, well into the radio portion of the spectrum.
The amount of RF energy typically decreases with frequency; so, for instance, interference in the medium wave US AM broadcast band in the one megahertz region may be strong, while interference with the FM broadcast band around megahertz may be considerably less.
Distance is a factor; the closer the interference is to a radio receiver, the more intense it will be. Even WiFi reception in the gigahertz range can be degraded if the receiving antennae are very close to a radiating AC adapter.
A determination of if interference is coming from a specific AC adaptor can be made simply by unplugging the suspect adapter while observing the amount of interference received in the problem radio band. In a modern household or business environment, there may be multiple AC adapters in use; in such a case, unplug them all, then plug them back in one by one until the culprit or culprits is found. External AC adapters are widely used to power small or portable electronic devices.
The advantages include:. A survey of consumers showed widespread dissatisfaction with the cost, inconvenience, and wastefulness of the profusion of power adapters used by electronic devices. The issue of inefficiency of some power supplies has become well known, with U.
Bush referring in to such devices as "Energy Vampires". Such initiatives include standby power and the One Watt Initiative. But others [ who? In most external plug-in "wall wart" power adapters commonly used for low-power consumer electronics devices were of linear design, as well as supplies built into some equipment.
External supplies are usually left plugged in even when not in use, and consume from a few watts to 35 watts of power in that state. Since the report was published, SMPSs have indeed replaced linear supplies to a great extent, even in wall warts. More efficient power supply designs could cut that usage in half". Since wasted electrical energy is released as heat , an inefficient power supply is hot to the touch, as is one that wastes power without an electrical load. This waste heat is itself a problem in warm weather, since it may require additional air conditioning to prevent overheating, and even to remove the unwanted heat from large supplies.
External power adapters can fail, and can become separated from the product they are intended to power. Consequently, there is a market for replacement adapters.
The replacement must match input and output voltages, match or exceed current capability, and be fitted with a matching connector. Many electrical products are poorly labeled with information concerning the power supply they require, so it is prudent to record the specifications of the original power supply in advance, to ease replacement if the original is later lost.
Careful labeling of power adapters can also reduce the likelihood of a mixup which could cause equipment damage. Some "universal" replacement power supplies allow output voltage and polarity to be switched to match a range of equipment. Adapters which can also be used with motor vehicle and aircraft power see EmPower are available.
Four-way X connectors or six-way star connectors , also known as spider connectors , with multiple plug sizes and types are common on generic power supplies. Other replacement power supplies have arrangements for changing the power connector, with four to nine different alternatives available when purchased in a set. RadioShack sells universal AC adapters [ when? This allows many different configurations of AC adapters to be put together, without requiring soldering.
Philmore and other competing brands offer similar AC adapters with interchangeable connectors. The label on a power supply may not be a reliable guide to the actual voltage it supplies under varying conditions. Many low-cost power supplies are " unregulated ", in that their voltage can change considerably with load. If they are lightly loaded, they may put out much more than the nominal "name plate" voltage, which could damage the load. If they are heavily loaded, the output voltage may droop appreciably, in some cases well below the nominal label voltage even within the nominal rated current, causing the equipment being supplied to malfunction or be damaged.
Supplies with linear as against switched regulators are heavy, bulky, and expensive. Modern switched-mode power supplies SMPSs are smaller, lighter, and more efficient. They put out a much more constant voltage than unregulated supplies as the input voltage and the load current vary. When introduced, their prices were high, but by the early 21st century the prices of switch-mode components had dropped to a degree which allowed even cheap supplies to use this technology, saving the cost of a larger and heavier mains-frequency transformer.
Some universal adapters automatically set their output voltage and maximum current according to which of a range of interchangeable tips is fitted; tips are available to fit and supply appropriate power to many notebook computers and mobile devices.
Different tips may use the same connector, but automatically supply different power; it is essential to use the right tip for the apparatus being powered, but no switch needs to be set correctly by the user. The advent of switch-mode power supplies has allowed adapters to work from any AC mains supply from to V with an appropriate plug; operation from standard 12 V DC vehicle and aircraft supplies can also be supported. With the appropriate adapter, accessories, and tips, a variety of equipment can be powered from almost any source of power.
A "Green Plug" system has been proposed, based on USB technology, by which the consuming device would tell the external power supply what kind of power is needed.
In early laptop computers, the power supply units were internal like in desktop computers. To facilitate portability by sparing physical space and reducing the weight, power supply units were externalized. When a laptop computer is operated while recharging, the integrated circuitry which controls the charging makes use of a power supply unit's remaining electrical current capacity.
This allows supplying the device's components with power during usage while maintaining an uncompromised constant charging speed. The USB connector and voltage has emerged as a de facto standard in low-power AC adapters for many portable devices. The trend towards more-compact electronic devices has driven a shift towards the micro-USB and mini-USB connectors, which are electrically compatible in function to the original USB connector but physically smaller.
In , a USB Power Delivery Specification was proposed to standardize delivery of up to watts, suitable for devices such as laptop computers that usually depend on proprietary adapters. The ITU recommendation was expanded and updated in June, The European Union defined a Common external power supply for "hand-held data-enabled mobile phones" smartphones sold from , intended to replace the many incompatible proprietary power supplies and eliminate waste by reducing the total number of supplies manufactured.
In Larry Page , a founder of Google , proposed a 12 V and up to 15 A standard for almost all equipment requiring an external converter, with new buildings fitted with 12 VDC wiring, making external AC-to-DC adapter circuitry unnecessary.
