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

Every mobile phone, laptop, and tablet seem to come with their own charger.  If you’re 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, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?

Types of Chargers

In this guide, we’ll concentrate 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 rather unique to the device they include.  However, there may be some generic chargers which boast the ability to be interchanged between laptops.  This always requires changing of the 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 most smartphones, Android devices, 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 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 for use on a different 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 as far as charging heads, whilst notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is only 1 part of this equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you’ll find a tag with the charger’s voltage (V) and amperage (A).  For other types of chargers, like a smartphone charger, this information is usually found at the bottom of the charger, where it would meet up with the wall.  For the device you’re 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 device, or just how much is being”pushed” to the device by the charger.  A phone will usually pull up to approximately 5V, though a laptop can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how fast power is”pulled” into the device, or how much power is used by the device.  The quantity of volts won’t ever change, but the amount of amps that the device pulls may change based 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 that may be pulled by the device.  If a unit is paired with a charger that cannot support the amp necessity, it can burn out the power supply and kill the apparatus.

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 (so long as the voltage is equivalent ).  *Website 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 Isn’t 5v…

Some devices may have their voltage listed with 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 rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts.  So this means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equivalent to or higher than the device’s listed amperage).

An interesting thing to note is all chargers provide a higher voltage than the batteries that they charge.  That’s pretty much how they operate.  There has to be a voltage differential to generate the necessary current flow in the correct way to charge the battery.  If you look at your vehicle, 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 frequently don’t support the energy requirements of the apparatus, or aren’t built to keep 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 come with your smart phone, notebook, camera, tabletcomputer, or other device.  Make certain to follow exactly what we said and you should be good to go!
