Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet? 

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

Kinds 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.  While some devices have chargers with a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly unique to the device they include.  However, there can 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 optimal charging amperage or voltage for your device.

Micro USBs are theoretically 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 different 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 port, a connector can be used to control the Lightning Connector.

The Plugs Must Be The Same

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 unit.  Micro USBs are the same across the board as far as charging heads, while laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only one part of the equation.

Determined by the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A).  For notebook chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually found at the base of the charger, where it would meet the wall.  For the device you are trying 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 in the device, or just how much is being”pushed” to the device by the charger.  A phone will usually pull up to around 5V, while a notebook can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device.  The quantity of volts will never change, but the amount of amps that the system pulls may change depending 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.  To be able to exchange 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 which can’t support the amp necessity, 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 faster charging (so long as the voltage is equivalent ).  *Website Note: if you have an older device, it may not work with USB interfaces that use the new Battery Charging Specification.

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

Some devices might have their voltage recorded with 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% of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts. 

An interesting thing to note is all chargers supply a higher voltage than the batteries they charge.  That is 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.  If you look at your vehicle, 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, especially cheap knockoffs, is they often don’t support the power needs of the device, or aren’t built to maintain a steady flow safely.  Overall, it’s better to stick with the charger made for the device you’re using.

Now You Understand How to Safely & Effectively Swap Chargers

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