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

Every mobile phone, notebook, and tablet seem 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, notebook, camera, or tablet computer that is not the original manufacturer’s charger that came with the device?

Kinds of Chargers

In this guide, 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 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 may 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 many smartphones, Android devices, 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 (based on its recorded amps and voltage).

For older devices using a 30-pin charge interface, a connector can be used to control the Lightning Connector.

In order for a charger to be used on another 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 notebook chargers are usually specific to both make and model.  However, the plug fitting securely is only one part of the equation.

Somewhere on the power brick of the charger you will 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 found at the base of the charger, in which it would meet up with the wall.  For the device you’re trying to control, 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 in the apparatus, or just 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 required by the device. 

Amperage is how fast power is”pulled” into the apparatus, or how much electricity is used by the device.  The quantity of volts will never change, but the amount of amps that the device pulls may change based on how hard the device is working.  The number that you find on the battery that came with your device will be the max amount of amps which may be pulled by the device.  The number found on the charger is how many amps can be pulled at once. To be able to swap 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 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 Is Not 5v…

Some devices may have their voltage listed using a plus/minus on it like this: 5v +- 5%.  If this is true, you can 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% of 5v = 4.75 volts  OR  5v plus 5 percent of 5v = 5.25 volts.  So 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 supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There needs to be a voltage differential to generate the necessary current flow in the correct way to charge the battery.  When you look at your car, 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, particularly cheap knockoffs, is that they frequently don’t support the energy requirements of the device, or are not built to maintain 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 designed for the device you’re 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 come with your smart phone, notebook, camera, tablet, or other device.  Make certain you follow exactly what we said and you should be ready to go!
