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

Every cell phone, laptop, and tablet seem to come with their own charger.  If you’re like me, you’ve 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 that is not the original manufacturer’s charger that came with the device?

Types of Chargers

In this guide, we will focus on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, 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 can 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 optimal charging amperage or voltage to 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 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 (depending on its recorded amps and voltage).

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

For a charger to be used on a different device, it’s important that the plug  of the charger (the”head”) fit snugly to the charging port of the device.  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 only 1 part of the equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you will find 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 bottom of the charger, where it would meet the wall.  For the device you are attempting to charge, the voltage and amperage required will be found 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 just how much is being”pushed” to the device by the charger.  A phone will usually pull up to around 5V, though 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 power 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 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.  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 which can’t support the amp requirement, it may burn out the power source and kill the device.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (so long as the voltage is equivalent ).  *Site Note: if you have an older device, it may not work with USB interfaces that employ the newest Battery Charging Specification.

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

Some devices might have their voltage recorded using a plus/minus on it like that: 5v +- 5%.  If this is the case, 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 and 5% of 5v = 5.25 volts. 

An interesting point to note is all chargers provide a higher voltage than the batteries that 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 car, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem 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 securely.  Overall, it’s better to stay 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 efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device.  Make sure you follow what we said and you should be ready to go!
