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

Every cell phone, notebook, and tablet seem to come with their own charger.  If you are like me, you have probably compiled a number of chargers through the years.  So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that isn’t the original manufacturer’s charger which 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 telephones, tablets, 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 rather specific to the device they include.  However, there can be some generic chargers that boast the ability to be interchanged between notebooks.  This always requires changing of the charger”head” and might not be the optimal charging amperage or voltage to 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 various amps.  I’ll 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 using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.

The Plugs Must Be The Same

In order for a charger to be used on a different device, it’s important 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 so far as charging heads, whilst laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only one part of the 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 notebook chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located 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 manufacturer’s website.

Voltage is how much power the charger will draw into 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 notebook can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how quickly power is”pulled” into the device, or how much power is used by the device.  The quantity of volts won’t ever change, but the quantity of amps that the system pulls may change depending on how hard the device is working.  The number that you find on the battery that came with your device will be the maximum amount of amps which may be pulled from the device.  If a device is paired with a charger which can’t support the amp necessity, it may burn out the power source 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 (so long as the voltage is equal).  *Website Note: if you have an older device, it might not work with USB interfaces that use the newest Battery Charging Specification.

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

Some devices may have their voltage recorded with a plus/minus on it like that: 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% 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 greater than the device’s listed amperage).

An interesting point to note is chargers provide a higher voltage than the batteries that they charge.  That is pretty much how they operate.  There needs to be a voltage differential to produce 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 issue with knockoffs, particularly cheap knockoffs, is they often don’t support the energy requirements of the apparatus, or are not built to keep a steady flow securely.  Overall, it’s best 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 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 apparatus.  Be sure to follow what we said and you should be good to go!
