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

Every cell phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you’ve probably compiled a number of chargers through the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?

Types of Chargers

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

Laptop chargers are rather specific to the device they come with.  However, there can be some generic chargers which boast the capability to be interchanged between laptops.  This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage to your device.

Micro USBs are 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 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, such as iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.

In order for a charger for use on a different device, it’s important 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 laptop chargers are often specific to both make and model.  However, the plug fitting securely is only 1 part of this equation.

Somewhere on 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 base of the charger, in which it would meet up with the wall.  For the device you’re attempting to charge, the voltage and amperage required will be found 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 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 needed 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 fast 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 amount of amps that the device pulls may change based on how hard the unit is working.  The number that you locate on the battery that came with your device are the max amount of amps that may be pulled by the device.  If a unit is paired with a charger that cannot support the amp requirement, it can burn out the power supply 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 equal).  *Site Note: if you have an older device, it might not work with USB ports that employ the newest Battery Charging Specification.

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

Some devices might have their voltage listed using 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 device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v plus 5 percent of 5v = 5.25 volts. 

An interesting thing to note is chargers provide a higher voltage than the batteries that they charge.  That’s pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery.  When you look at your vehicle, it’s 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 often don’t support the power requirements of the device, or aren’t built to keep a steady flow securely.  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 made for the device you are using.

Now You Know How To Safely & Effectively Swap Chargers

I hope this article was able to help you.  Now you know how to safely and efficiently use a charger that did not include your smart phone, laptop, camera, tablet, or other apparatus.  Be certain you follow what we said and you should be good to go!
