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 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 that came with the device?

Kinds of Chargers

In this article, we will focus 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 using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly specific to the device they come with.  However, there may be some generic chargers which boast the capability to be interchanged between laptops.  This always requires changing of the 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 most 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 whether the charger is safe to use (depending on its recorded amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge port, a connector can be used to control the Lightning Connector.

For a charger for use on a different device, it’s important that the plug  of the charger (the”head”) fit snugly to the charging port of the unit.  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.

How Voltage and Amperage Matter

Determined by 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 found at the base of the charger, in which it would meet the wall.  For the device you are attempting to control, 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 device, or 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.  This is important: drawing too high a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device.  The quantity of volts won’t ever change, but the quantity of amps that the system pulls may change depending on how hard the device 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 from 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 that cannot 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 quicker charging (as long as the voltage is equal).  *Site Note: if you have an older device, it might not work with USB ports that use the new 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 the case, 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 plus 5% of 5v = 5.25 volts. 

An interesting point to note is chargers provide a higher voltage than the batteries that they charge.  That’s pretty much how they operate.  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 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 that they frequently don’t support the energy requirements of the device, or aren’t built to keep a steady flow safely.  This can result in damage to the device but can also pose a safety/fire hazard. 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 efficiently use a charger that did not come with your smart phone, notebook, camera, tablet, or other apparatus.  Make certain to follow what we said and you should be ready to go!
