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

Every mobile phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you have probably compiled quite a few chargers over 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 guide, we’ll focus on three types of chargers: laptop 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 common.

Laptop chargers are fairly unique to the device they come with.  However, there may be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of this charger”head” and may 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 devices, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw different amps.  I’ll explain this further later and how to know whether the charger is safe to use (based on its recorded amps and voltage).

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

The Plugs Must Be The Same

In order for a charger for use on another 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 so far as charging heads, whilst laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only one part of this equation.

How Voltage and Amperage Matter

Somewhere on the power brick of the charger you will 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 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 manufacturer’s website.

Voltage is how much power the charger will draw into the apparatus, 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 needed by the device. 

Amperage is how quickly power is”pulled” into the apparatus, or how much electricity is used by the device.  The amount of volts won’t ever change, but the amount of amps that the system pulls may change based on how hard the device is working.  The number that you locate on the battery that came with your device are the maximum amount of amps that may be pulled by the device.  In order to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. 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 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 faster charging (so long as the voltage is equivalent ).  *Site Note: if you have an older device, it may not work with USB ports that use the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Isn’t 5v…

Some devices might have their voltage recorded using a plus/minus on it like this: 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v plus 5% of 5v = 5.25 volts. 

An interesting thing to note is all chargers provide 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 correct way to charge the battery.  When you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The issue with knockoffs, especially cheap knockoffs, is that they often don’t support the energy needs of the apparatus, or are not built to keep a steady flow securely.  This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stick with the charger designed 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 effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Be certain you follow exactly what we said and you should be ready to go!
