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

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

Types of Chargers

In this article, we’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors.  While 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 capability to be interchanged between laptops.  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 most smartphones, Android devices, and tablets.  Micro USB chargers typically have the same voltage, but may draw various amps.  I will explain this further later and how to know whether the charger is safe to use (based on its listed amps and voltage).

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

In order for a charger to be used on another device, it’s important 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, while notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is only one part of this equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you’ll find a tag 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 found at the base of the charger, where it would meet up with the wall.  For the device you are attempting 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 apparatus, or how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to around 5V, though a laptop can pull up to 25V.  A charger must equal the voltage required by the device.  This is important: drawing too high of a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how fast power is”pulled” into the device, or how much electricity is used by the device.  The amount of volts won’t ever change, but the amount of amps that the system pulls may change based on how hard the unit is working.  The number that you find on the battery that came with your device are the maximum amount of amps that may be pulled by the device.  The amount found on the charger is how many amps can be pulled simultaneously. If a unit is paired with a charger which can’t support the amp necessity, it can burn out the power supply and kill the device.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equivalent ).  *Website Note: if you have an older device, it might not work with USB ports that use the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Isn’t 5v…

Some devices might have their voltage listed using 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 apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v plus 5 percent of 5v = 5.25 volts. 

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 has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery.  If you look at your vehicle, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the energy needs of the apparatus, or are not built to keep a steady flow securely.  Overall, it’s best to stay 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 include your smart phone, laptop, camera, tablet, or other device.  Make sure to follow exactly what we said and you should be ready to go!
