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

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

Types 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.  Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly specific to the device they come with.  However, there can be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of this charger”head” and may not be the optimal charging amperage or voltage to your device.

Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets.  Micro USB chargers typically have the 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).

For older devices using a 30-pin charge interface, a connector can be used to control the Lightning Connector.

The Plugs Must Be The Same

In order for a charger for use on another device, it’s essential 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 so far as charging heads, whilst notebook chargers are usually specific to both make and model.  However, the plug fitting securely is just one part of the equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you’ll get a label 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, 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 apparatus, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to around 5V, while a laptop 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 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 find on the battery that came with your device are the max amount of amps that may be pulled by the device.  The number found on the charger is how many amps can be pulled at once. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. 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 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 (as long as the voltage is equivalent ).  *Site Note: if you have an older device, it may not work with USB ports that use the newest Battery Charging Specification.

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

Some devices may have their voltage listed with a plus/minus on it like that: 5v +- 5%.  If this is the case, you may use a charger rated at 4.75 to 5.25v because that rating is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts  OR  5v plus 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’s pretty much how they operate.  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 vehicle, 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 problem with knockoffs, especially cheap knockoffs, is that they often don’t support the energy requirements of the apparatus, or aren’t built to maintain a steady flow securely.  Overall, it’s better to stick with the charger designed 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 come with your smart phone, notebook, camera, tablet, or other device.  Be certain to follow what we said and you should be ready to go!
