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

Every mobile phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you have 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 which came with the device?

Kinds of Chargers

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

Laptop chargers are rather specific to the device they come with.  However, there may be some generic chargers that boast the capability to be interchanged between laptops.  This always requires changing of this charger”head” and may not be the best charging amperage or voltage for your device.

Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw different amps.  I will explain this further later and how to know if the charger is safe to use (depending on its listed amps and voltage).

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

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 unit.  Micro USBs are the same across the board as far as charging heads, whilst laptop chargers are usually specific to both make and model.  However, the plug fitting firmly is just one part of the equation.

Somewhere on the power brick of the charger you will find 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 the wall.  For the device you are trying to charge, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’s website.

Voltage is how much power the charger will draw into the device, or how much is being”pushed” into 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 required by the device. 

Amperage is how fast power is”pulled” into the apparatus, or how much electricity is used by the device.  The quantity of volts will never change, but the amount 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.  The amount found on the charger is how many amps can be pulled at once. To be able to swap 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 which can’t support the amp requirement, it may burn out the power supply and kill the apparatus.

So for those who 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 new Battery Charging Specification.

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

Some devices may have their voltage listed 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 rating is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts. 

An interesting thing to note is chargers supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There needs to be a voltage differential to generate the necessary current flow in the correct direction to charge the battery.  When you look at your vehicle, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, particularly cheap knockoffs, is they often don’t support the power requirements of the device, or aren’t built to keep a steady flow safely.  Overall, it’s best 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 assist you.  Now you know how to safely and efficiently use a charger that did not come with your smart phone, laptop, camera, tablet, or other device.  Be certain you follow exactly what we said and you should be good to go!
