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

Every cell phone, notebook, and tablet seem to come with their own charger.  If you are like me, you’ve 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 that isn’t the original manufacturer’s charger that came with the device?

Kinds of Chargers

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

Laptop chargers are fairly specific to the device they include.  However, there may 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 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 (depending on its recorded amps and voltage).

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

For a charger to be used 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 notebook chargers are usually specific to both make and model.  However, the plug fitting securely is only one 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 bottom of the charger, in which it would meet up with the wall.  For the device you’re attempting 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 into the device, or just 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 fast power is”pulled” to the device, or how much electricity is used by the device.  The quantity of volts won’t ever change, but the quantity of amps that the device pulls may change depending on how hard the unit is working.  The number that you locate on the battery that came with your device are the max amount of amps which may be pulled from the device.  The number found on the charger is how many amps can be pulled at once. If a device is paired with a charger that cannot support the amp requirement, it can burn out the power source and kill the device.

So if you have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equivalent ).  *Website Note: if you have an older device, it may 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 with a plus/minus on it like that: 5v +- 5%.  If this is the case, you can use a charger rated at 4.75 to 5.25v because that rating is telling you is that the apparatus 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 they charge.  That’s pretty much how they operate.  There has to be a voltage differential to generate the necessary current flow in the proper direction 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, particularly cheap knockoffs, is that they often don’t support the power requirements of the device, or are not built to maintain a steady flow securely.  Overall, it’s best to stay with the charger designed for the device you’re using.

Now You Know 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 come with your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Be sure you follow exactly what we said and you should be ready to go!
