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 are like me, you’ve probably compiled a number of chargers over 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 that came with the device?

Types of Chargers

In this article, we’ll 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 rather unique to the device they include.  However, there may be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of this charger”head” and might not be the best charging amperage or voltage to your device.

Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android devices, 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 whether the charger is safe to use (based on its listed amps and voltage).

For older devices with a 30-pin charge interface, 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 unit.  Micro USBs are the same across the board so far as charging heads, while notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is just one part of this equation.

Determined by the power brick of the charger you will find a tag with the charger’s voltage (V) and amperage (A).  For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. 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’re trying to charge, the voltage and amperage required will be seen 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 device, or how much is being”pushed” into the device 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 potentially 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 electricity is used by the device.  The amount 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 can be pulled by the device.  The number found on the charger is how many amps can be pulled at once. 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 unit is paired with a charger that cannot support the amp necessity, it may burn out the power source and kill the apparatus.

So for those who have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equal).  *Site Note: if you have an older device, it may not work with USB ports that use the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Is Not 5v…

Some devices might have their voltage listed with a plus/minus on it like this: 5v +- 5%.  If this is the case, 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 and 5 percent of 5v = 5.25 volts.  So this means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).

An interesting point to note is all chargers supply a higher voltage than the batteries that they charge.  That is pretty much how they operate.  There needs to be a voltage differential to produce the necessary current flow in the proper way to charge the battery.  When you look at your car, 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 that they often don’t support the power requirements of the apparatus, or aren’t built to keep a steady flow securely.  Overall, it’s best 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 help you.  Now you know how to safely and efficiently use a charger that did not come with your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Make sure to follow what we said and you should be good to go!
