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

Every cell phone, laptop, and tablet seem to come with their own charger.  If you’re like me, you have 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 that is not the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this guide, we’ll 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 with a slightly different head or charging cable, these are the most common.

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 notebooks.  This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage to 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’ll explain this further later and how to know whether the charger is safe to use (depending on its listed amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices using a 30-pin charge port, a connector can be used to charge with 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 snugly to the charging port of the device.  Micro USBs are the same across the board so far as charging heads, while laptop chargers are usually specific to both make and model.  However, the plug fitting firmly 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 other types of chargers, like a smartphone charger, this information is usually found at the bottom of the charger, in which it would meet the wall.  For the device you’re attempting to charge, 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 apparatus, or how much is being”pushed” into the apparatus by the charger.  A phone will usually pull up to around 5V, while a laptop can pull up to 25V.  A charger must equal the voltage needed 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 amount of amps that the device pulls may change based 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 which can be pulled by the device.  To be able to swap 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 can burn out the power source and kill the device.

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 (so long as the voltage is equal).  *Site Note: if you have an older device, it might 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 with a plus/minus on it like that: 5v +- 5%.  If this is true, you may 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 plus 5% of 5v = 5.25 volts. 

An interesting point 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 generate the necessary current flow in the correct direction to charge the battery.  If you look at your car, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, particularly cheap knockoffs, is they often don’t support the power needs of the device, or aren’t built to maintain a steady flow securely.  Overall, it’s best to stay with the charger made 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 effectively 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 ready to go!
