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

Every mobile phone, notebook, and tablet seem to come with their own charger.  If you’re like me, you have probably compiled a number of chargers over the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that is not the original manufacturer’s charger which came with the device?

Types 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 with a slightly different head or charging cable, these are the most common.

Laptop chargers are rather specific to the device they come with.  However, there can be some generic chargers that boast the capability to be interchanged between notebooks.  This always requires changing of the 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 most smartphones, Android devices, and tablets.  Micro USB chargers typically have the exact 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).

Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices with a 30-pin charge port, 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 essential that the plug  of the charger (the”head”) fit snugly to the charging port of the device.  Micro USBs are the same across the board as far as charging heads, whilst laptop chargers are often specific to both make and model.  However, the plug fitting securely 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, where it would meet up with the wall.  For the device you’re attempting to control, the voltage and amperage required will be found 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” into the apparatus, or how much electricity is used by the device.  The quantity of volts won’t ever change, but the amount 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 will be the maximum amount of amps that can be pulled by the device.  If a device is paired with a charger which can’t 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, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equivalent ).  *Site Note: if you have an older device, it might not work with USB ports that employ the new Battery Charging Specification.

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

Some devices may have their voltage listed using a plus/minus on it like this: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that rating is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v plus 5% of 5v = 5.25 volts.  This means anything between 4.75 t0 5.25v is safe to use (as 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 operate.  There has to be a voltage differential to generate the necessary current flow in the proper 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 problem with knockoffs, particularly cheap knockoffs, is they often don’t support the power requirements of the apparatus, or are not built to maintain a steady flow safely.  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 come with your smart phone, laptop, camera, tabletcomputer, or other device.  Make certain you follow what we said and you should be good to go!
