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

Every mobile phone, notebook, and tablet appear to come with their own charger.  If you’re like me, you’ve probably compiled quite a few 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 which came with the device?

Kinds of Chargers

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

Laptop chargers are rather specific to the device they include.  However, there may be some generic chargers that boast the ability 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 designed to be interchangeable, and are standard in many 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 if the charger is safe to use (based on its listed amps and voltage).

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

In order for a charger to be used on a different 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 as far as charging heads, whilst notebook chargers are often 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 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 bottom of the charger, where it would meet up with the wall.  For the device you are 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 in the apparatus, or just how much is being”pushed” into the device by the charger.  A phone will usually pull up to around 5V, though a laptop 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 power is used by the device.  The amount of volts won’t ever change, but the amount of amps that the system 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 maximum amount of amps which may be pulled by the device.  The number found on the charger is how many amps can be pulled simultaneously. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. 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 for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (so long as the voltage is equivalent ).  *Site Note: if you have an older device, it might not work with USB interfaces that use the newest 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 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% of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts. 

An interesting point to note is all chargers provide a higher voltage than the batteries they charge.  That is pretty much how they operate.  There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery.  When you look at your car, 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 issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power needs of the device, or are not built to keep a steady flow securely.  Overall, it’s best to stick with the charger made 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 efficiently use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other apparatus.  Be sure to follow what we said and you should be good to go!
