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

Every mobile 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 is not the original manufacturer’s charger that came with the device?

Kinds of Chargers

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

Laptop chargers are rather unique to the device they come with.  However, there may be some generic chargers which 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 theoretically designed to be interchangeable, and are standard in many smartphones, Android apparatus, 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 if the charger is safe to use (depending on its recorded amps and voltage).

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

The Plugs Must Be The Same

In order for a charger for use on another device, it’s essential 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, whilst notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is only 1 part of the equation.

Somewhere on the power brick of the charger you will 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 located at the base of the charger, in which it would meet 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 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, while a laptop can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how quickly power is”pulled” to the device, or how much electricity is used by the device.  The amount of volts will never change, but the quantity 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 which may be pulled by 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 which can’t support the amp requirement, it may burn out the power source and kill the apparatus.

So for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equivalent ).  *Site Note: if you have an older device, it may not work with USB interfaces that employ the newest Battery Charging Specification.

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

Some devices may have their voltage listed 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 5% 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 greater than the device’s listed amperage).

An interesting thing to note is all chargers supply a higher voltage than the batteries they charge.  That is pretty much how they work.  There has to be a voltage differential to produce the necessary current flow in the correct way to charge the battery.  If you look at your vehicle, it’s 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, particularly cheap knockoffs, is that they often don’t support the energy needs of the device, or aren’t built to keep a steady flow safely.  Overall, it’s better to stay with the charger designed for the device you’re 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 efficiently use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other device.  Make sure you follow what we said and you should be good to go!
