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 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 isn’t the original manufacturer’s charger that came with the device?

Types of Chargers

In this article, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly 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 to 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 exact same voltage, but may draw various 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).

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

The Plugs Must Be The Same

In order 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 unit.  Micro USBs are the same across the board as far as charging heads, while notebook chargers are often specific to both make and model.  However, the plug fitting securely is just one part of the equation.

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 found at the bottom of the charger, in which it would meet the wall.  For the device you’re trying to control, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’s website.

Voltage is how much power the charger will draw into the apparatus, or how much is being”pushed” into 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 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 won’t ever change, but the amount of amps that the system pulls may change based on how hard the unit is working.  The number that you locate on the battery that came with your device are the maximum amount of amps which can be pulled by the device.  If a unit is paired with a charger which can’t support the amp requirement, it may burn out the power source and kill the apparatus.

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 (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 new 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 this: 5v +- 5%.  If this is the case, 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 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 (as long as the amperage of the charger is equal to or higher than the device’s listed amperage).

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

The issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power requirements of the device, or aren’t built to keep a steady flow securely.  This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stay with the charger designed 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 effectively use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other apparatus.  Make sure to follow what we said and you should be ready to go!
