How To Repair Hp Laptop Battery

Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet? 

Every mobile phone, laptop, and tablet seem to come with their own charger.  If you are like me, you have probably compiled a number of chargers through the years.  So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this article, we’ll concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are rather specific to the device they include.  However, there may be some generic chargers that boast the capability to be interchanged between notebooks.  This always requires changing of this charger”head” and might not be the best charging amperage or voltage to your device.

Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the same voltage, but may draw various amps.  I will explain this further later and how to know whether the charger is safe to use (depending on its listed amps and voltage).

For older devices using a 30-pin charge interface, a connector can be used to control the Lightning Connector.

In order for a charger for use on a different device, it’s important that the plug  of the charger (the”head”) fit snugly to the charging port of the unit.  Micro USBs are the same across the board as far as charging heads, whilst notebook chargers are usually specific to both make and model.  However, the plug fitting securely is just one part of the equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A).  For other types of chargers, like a smartphone charger, this information is usually found at the base of the charger, in which it would meet up with the wall.  For the device you’re attempting to charge, the voltage and amperage required will be found on the battery that came with the device or on the company’s website.

Voltage is how much power the charger will draw into the device, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to around 5V, while a laptop can pull up to 25V.  A charger must equal the voltage required by the device.  This is important: drawing too high a voltage could short out the device and possibly even start a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” into the apparatus, or how much electricity is used by the device.  The amount of volts will never change, but the amount of amps that the system pulls may change depending on how hard the unit is working.  The number that you find on the battery that came with your device will be the maximum amount of amps that may be pulled from the device.  The amount found on the charger is how many amps can be pulled simultaneously. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a unit is paired with a charger which can’t support the amp necessity, it can burn out the power supply and kill the apparatus.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equal).  *Website Note: if you have an older device, it may not work with USB ports that employ the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Is Not 5v…

Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that score is telling you is that the apparatus can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts. 

An interesting point to note is chargers provide a higher voltage than the batteries that they charge.  That is pretty much how they work.  There needs to be a voltage differential to generate the necessary current flow in the proper way to charge the battery.  When you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

The issue with knockoffs, especially cheap knockoffs, is that they often don’t support the energy needs of the apparatus, or aren’t built to keep a steady flow safely.  Overall, it’s best to stay with the charger made for the device you are using.

Now You Understand How to Safely & Effectively Swap Chargers

I hope this article was able to assist you.  Now you know how to safely and efficiently use a charger that did not come with your smart phone, laptop, camera, tablet, or other apparatus.  Make sure you follow what we said and you should be ready to go!
