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

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

Kinds of Chargers

In this guide, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using a slightly different head or charging cable, these are the most common.

Laptop chargers are rather unique to the device they come with.  However, there may be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of this 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 most smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw various amps.  I will explain this further later and how to know whether the charger is safe to use (based on its recorded amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to control the Lightning Connector.

The Plugs Must Be The Same

For a charger for use on another device, it’s important that the plug  of the charger (the”head”) fit securely into the charging port of the device.  Micro USBs are the same across the board so far as charging heads, while laptop 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 will find a tag with the charger’s voltage (V) and amperage (A).  For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located at the base of the charger, where it would meet up with the wall.  For the device you are trying to control, the voltage and amperage required will be seen 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 apparatus by the charger.  A phone will usually pull up to around 5V, though a notebook can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how quickly power is”pulled” into the device, or how much electricity is used by the device.  The quantity of volts won’t ever change, but the amount of amps that the system pulls may change depending on how hard the unit is working.  The number that you locate on the battery that came with your device will be the maximum amount of amps that can be pulled by the device.  If a device is paired with a charger that cannot support the amp necessity, it may burn out the power source and kill the device.

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 (as long as the voltage is equal).  *Website Note: if you have an older device, it might not work with USB ports that employ the new Battery Charging Specification.

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

Some devices might have their voltage recorded using a plus/minus on it like this: 5v +- 5%.  If this is true, you can 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 percent of 5v = 4.75 volts  OR  5v plus 5 percent of 5v = 5.25 volts. 

An interesting thing to note is all chargers supply a higher voltage than the batteries that they charge.  That is pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery.  When you look at your vehicle, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

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

Now You Know How To Safely & Effectively Swap Chargers

I hope this article was able to help 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 certain to follow what we said and you should be good to go!
