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

Every mobile phone, laptop, and tablet seem to come with their own charger.  If you are 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, laptop, camera, or tablet computer that is not the original manufacturer’s charger that came with the device?

Kinds of Chargers

In this article, we’ll 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 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 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 most 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 (based on its listed amps and voltage).

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

In order for a charger to be used on a different device, it’s essential 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 as far as charging heads, whilst notebook chargers are often specific to both make and model.  However, the plug fitting securely is only one part of the equation.

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 found at the base of the charger, where 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 manufacturer’s website.

Voltage is how much power the charger will draw in the apparatus, or just how much is being”pushed” into the device 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. 

Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device.  The quantity of volts will never change, but the quantity of amps that the device pulls may change based on how hard the unit is working.  The number that you locate on the battery that came with your device will be the max amount of amps which can be pulled by the device.  If a device is paired with a charger that cannot support the amp necessity, it can burn out the power supply and kill the apparatus.

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 equal).  *Site Note: if you have an older device, it might not work with USB interfaces that use the new Battery Charging Specification.

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

Some devices might have their voltage listed with a plus/minus on it like that: 5v +- 5%.  If this is true, 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 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 thing to note is all chargers provide a higher voltage than the batteries they charge.  That is pretty much how they operate.  There needs to be a voltage differential to generate the necessary current flow in the correct direction to charge the battery.  If you look at your car, it’s a 12V battery, but average 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 power requirements of the device, or are not built to keep a steady flow safely.  Overall, it’s better to stick 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 come with your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Be certain you follow exactly what we said and you should be ready to go!
