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

Every mobile phone, notebook, and tablet seem to come with their own charger.  If you’re like me, you have 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 isn’t the original manufacturer’s charger that came with the device?

Kinds of Chargers

In this guide, we’ll concentrate 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 using a slightly different head or charging cable, these are the most common.

Laptop chargers are rather specific to the device they come with.  However, there may be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage for 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’ll explain this further later and how to know if 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 charge with the Lightning Connector.

The Plugs Must Be The Same

In order for a charger to be used on another device, it’s essential 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, while laptop chargers are usually specific to both make and model.  However, the plug fitting firmly is only 1 part of this equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you will get a tag 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, in which it would meet the wall.  For the device you’re attempting 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 how much is being”pushed” to 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.  This is important: drawing too high of a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly 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 amount of amps that the device pulls may change based on how hard the unit is working.  The number that you find on the battery that came with your device are the max amount of amps that can be pulled from 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 device 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 quicker 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 using a plus/minus on it like this: 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 percent of 5v = 4.75 volts  OR  5v plus 5% of 5v = 5.25 volts.  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 higher than the device’s listed amperage).

An interesting point to note is chargers supply a higher voltage than the batteries that they charge.  That’s pretty much how they work.  There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery.  When you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the power requirements of the device, or are not built to keep a steady flow safely.  This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best 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 assist you.  Now you know how to safely and efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Make certain to follow exactly what we said and you should be ready to go!
