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

Every cell phone, notebook, and tablet seem to come with their own charger.  If you are 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 that is not the original manufacturer’s charger which came with the device?

Kinds of Chargers

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

Laptop chargers are rather unique 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 the charger”head” and may 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 devices, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw different 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).

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 charge with 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 snugly to the charging port of the unit.  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 firmly is only one part of the equation.

Somewhere on the power brick of the charger you’ll get 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, where it would meet up with the wall.  For the device you are 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 apparatus, or how much is being”pushed” into 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 needed by the device. 

Amperage is how fast power is”pulled” to the device, 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 can be pulled by the device.  The amount found on the charger is how many amps can be pulled at once. If a unit is paired with a charger that cannot support the amp necessity, it can burn out the power source and kill the device.

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 equivalent ).  *Website Note: if you have an older device, it may 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 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 rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts.  This means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equivalent to or higher than the device’s listed amperage).

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 generate the necessary current flow in the correct direction to charge the battery.  If you look at your vehicle, it has 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 often don’t support the energy needs of the device, or are not built to maintain 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 stay 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 effectively use a charger that did not include your smart phone, laptop, camera, tablet, or other device.  Be certain to follow what we said and you should be ready to go!
