How To Repair Samsung Battery

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

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

Kinds of Chargers

In this article, we will focus on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors.  While some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly unique to the device they include.  However, there can be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of the charger”head” and might not be the best charging amperage or voltage for your device.

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

Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices using a 30-pin charge port, 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 securely into the charging port of the unit.  Micro USBs are the same across the board so far as charging heads, whilst notebook chargers are often specific to both make and model.  However, the plug fitting firmly is only 1 part of the equation.

How Voltage and Amperage Matter

Somewhere on 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 located at the base of the charger, in which it would meet the wall.  For the device you are attempting to charge, the voltage and amperage required will be found on the battery that came with the device or on the manufacturer’s website.

Voltage is how much power the charger will draw in the apparatus, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device.  The quantity of volts will never change, but the quantity of amps that the system pulls may change based on how hard the device is working.  The number that you find on the battery that came with your device will be the max amount of amps that may be pulled from the device.  The amount found on the charger is how many amps can be pulled simultaneously. If a unit is paired with a charger which can’t support the amp necessity, it may burn out the power supply and kill the apparatus.

So for those who have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (so long as the voltage is equal).  *Site Note: if you have an older device, it might not work with USB interfaces that use the new Battery Charging Specification.

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

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

An interesting point to note is all chargers supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the proper way to charge the battery.  If 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 problem with knockoffs, especially cheap knockoffs, is that they often don’t support the power needs of the device, or are not built to maintain a steady flow safely.  Overall, it’s better to stay with the charger designed for the device you’re 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 include your smart phone, laptop, camera, tabletcomputer, or other apparatus.  Be sure you follow exactly what we said and you should be ready to go!
