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

Every cell phone, notebook, and tablet appear to come with their own charger.  If you are like me, you have 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 computer that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this article, 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.  Although some devices have chargers with a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly specific to the device they include.  However, there may be some generic chargers that boast the capability to be interchanged between notebooks.  This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage for your device.

Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the same voltage, but may draw various amps.  I’ll explain this further later and how to know if the charger is safe to use (based 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.

For a charger to be used on a different device, it’s important 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, while notebook chargers are usually specific to both make and model.  However, the plug fitting securely is just 1 part of this equation.

Determined by the power brick of the charger you will 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 located at the bottom of the charger, in which it would meet the wall.  For the device you are 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 into the apparatus, or 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.  This is important: drawing too high of a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how fast power is”pulled” into the device, or how much power is used by the device.  The quantity of volts will never change, but the amount of amps that the device pulls may change depending on how hard the device is working.  The number that you find on the battery that came with your device are the maximum amount of amps which can be pulled from the device.  To be able to exchange 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 necessity, it can burn out the power source and kill the device.

So if you have a modern USB device (smart phone, tablet, 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 recorded with a plus/minus on it like that: 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 device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v plus 5 percent of 5v = 5.25 volts. 

An interesting point to note is chargers supply a higher voltage than the batteries 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 direction to charge the battery.  If you look at your vehicle, it’s a 12V battery, but typical 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 better to stick 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 effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device.  Be sure to follow exactly what we said and you should be ready to go!
