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

Every cell phone, notebook, and tablet appear to come with their own charger.  If you are like me, you’ve 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 article, we will focus on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablets, 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 come with.  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 may not be the optimal charging amperage or voltage for 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 different amps.  I’ll explain this further later and how to know whether the charger is safe to use (depending on its recorded amps and voltage).

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

The Plugs Must Be The Same

For a charger to be used 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, while laptop chargers are often specific to both make and model.  However, the plug fitting securely is only one part of the equation.

Somewhere on the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A).  For notebook chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located at the bottom 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 company’s website.

Voltage is how much power the charger will draw in the device, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to approximately 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 will never change, but the amount of amps that the system pulls may change depending on how hard the device 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 from the device.  The number found on the charger is how many amps can be pulled at once. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a device is paired with a charger that cannot support the amp requirement, 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 quicker charging (so long as the voltage is equivalent ).  *Site 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 might have their voltage listed using a plus/minus on it like this: 5v +- 5%.  If this is the case, you can 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% of 5v = 5.25 volts. 

An interesting thing to note is all chargers provide a higher voltage than the batteries that they charge.  That’s pretty much how they work.  There needs to be a voltage differential to produce the necessary current flow in the proper way to charge the battery.  If you look at your car, it’s 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 energy needs of the device, or are not built to maintain a steady flow safely.  Overall, it’s best 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 effectively use a charger that did not include your smart phone, laptop, camera, tablet, or other apparatus.  Be certain to follow what we said and you should be good to go!
