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 are like me, you have probably compiled a number of chargers over the years.  So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that is not the original manufacturer’s charger that came with the device?

Kinds of Chargers

In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, 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 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 laptops.  This always requires changing of the charger”head” and may not be the optimal charging amperage or voltage for your device.

Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw different amps.  I’ll explain this further later and how to know whether 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.

The Plugs Must Be The Same

In order for a charger to be used 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 so far as charging heads, while laptop chargers are usually 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’ll find a label with the charger’s voltage (V) and amperage (A).  For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located at the base of the charger, where it would meet up with the wall.  For the device you are attempting to control, 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 apparatus, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to around 5V, though a notebook 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 start a fire, while too low a voltage will fail to charge the battery.

Amperage is how fast power is”pulled” to the apparatus, or how much electricity is used by the device.  The amount of volts will never change, but the quantity of amps that the device pulls may change depending 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 that can be pulled by the device.  If a device is paired with a charger that cannot support the amp requirement, it can burn out the power supply and kill the device.

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 quicker charging (so long as the voltage is equivalent ).  *Website Note: if you have an older device, it may not work with USB ports that use the new 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 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% of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts. 

An interesting thing 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 produce the necessary current flow in the correct 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.

Stay Away From Cheap Knockoff Chargers

The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power requirements of the apparatus, or are not built to keep a steady flow safely.  Overall, it’s best to stick with the charger designed for the device you are 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 effectively use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other device.  Be certain to follow what we said and you should be good to go!
