Can You Use Any Charger With Any Cell 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 quite a few chargers over the years.  So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?

Types of Chargers

In this guide, we will concentrate on three types of chargers: notebook 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 include.  However, there may be some generic chargers that boast the ability to be interchanged between notebooks.  This always requires changing of the charger”head” and might not be the best charging amperage or voltage for your device.

Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the same voltage, but may draw various amps.  I’ll explain this further later and how to know if the charger is safe to use (based on its recorded amps and voltage).

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

The Plugs Must Be The Same

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 usually 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 bottom of the charger, where it would meet the wall.  For the device you’re attempting 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 approximately 5V, though a laptop can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” into the apparatus, or how much electricity is used by the device.  The quantity of volts will never change, but the quantity 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 are the maximum amount of amps which may be pulled from the device.  In order to swap chargers, the amp number on the charger must equal or exceed the amp number recorded 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, tabletcomputer, 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 might not work with USB interfaces that use the new Battery Charging Specification.

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

Some devices may have their voltage listed with 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 rating is telling you is that the apparatus can take 5v minus 5 percent 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 (so long as the amperage of the charger is equal to or greater than the device’s listed amperage).

An interesting thing 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.  If 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 problem with knockoffs, particularly cheap knockoffs, is that they often don’t support the energy needs of the apparatus, or aren’t built to keep a steady flow securely.  Overall, it’s better to stick with the charger designed for the device you’re 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 effectively use a charger that did not come with your smart phone, notebook, camera, tablet, or other apparatus.  Make certain to follow exactly what we said and you should be good to go!
