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’re 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, notebook, camera, or tablet that isn’t the original manufacturer’s charger that came with the device?

Kinds of Chargers

In this article, we’ll focus on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors.  Although some devices have chargers with a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly unique to the device they come with.  However, there may be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of this charger”head” and might not be the best charging amperage or voltage for 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 same voltage, but may draw different amps.  I will 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 with 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 to be used on a different device, it’s essential that the plug  of the charger (the”head”) fit snugly to the charging port of the unit.  Micro USBs are the same across the board so far as charging heads, whilst laptop chargers are often specific to both make and model.  However, the plug fitting securely is only 1 part of this equation.

Somewhere on the power brick of the charger you will 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 found at the base of the charger, in which it would meet up with 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 company’s website.

Voltage is how much power the charger will draw into the apparatus, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” into the apparatus, or how much power is used by the device.  The quantity 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 will be the maximum amount of amps that may be pulled from the device.  The amount found on the charger is how many amps can be pulled at once. If a device is paired with a charger which can’t support the amp necessity, 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 (as long as the voltage is equivalent ).  *Site Note: if you have an older device, it might not work with USB ports that use the newest Battery Charging Specification.

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

Some devices might have their voltage recorded with a plus/minus on it like this: 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 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 equal to or higher than the device’s listed amperage).

An interesting point to note is all chargers supply a higher voltage than the batteries that they charge.  That is pretty much how they operate.  There has to be a voltage differential to generate the necessary current flow in the proper way 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 issue with knockoffs, especially cheap knockoffs, is they often don’t support the energy needs of the apparatus, or are not built to maintain a steady flow securely.  This can result in 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’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, laptop, camera, tablet, or other device.  Make sure to follow what we said and you should be ready to go!
