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

Every mobile phone, notebook, and tablet appear to come with their own charger.  If you are like me, you’ve probably compiled quite a few 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 which came with the device?

Kinds of Chargers

In this article, we’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, 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 fairly specific to the device they include.  However, there may be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of this charger”head” and may not be the best charging amperage or voltage to your device.

Micro USBs are designed to be interchangeable, and are standard in many 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 (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.

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 unit.  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 just 1 part of this equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you’ll get a label with the charger’s voltage (V) and amperage (A).  For notebook 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 bottom of the charger, in which it would meet up with the wall.  For the device you’re attempting to control, 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 apparatus by the charger.  A phone will usually pull up to around 5V, while a laptop can pull up to 25V.  A charger must equal the voltage required by the device.  This is important: drawing too high a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” into the apparatus, or how much electricity is used by the device.  The amount 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 are the maximum amount of amps which can be pulled from the device.  If a unit is paired with a charger that cannot support the amp requirement, it may burn out the power source and kill the device.

So if you have a modern USB device (smart phone, tablet, 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 may not work with USB ports that use the newest Battery Charging Specification.

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

Some devices might have their voltage recorded 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 score is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 5 percent 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 equivalent to or greater than the device’s listed amperage).

An interesting thing to note is chargers supply a higher voltage than the batteries that they charge.  That’s pretty much how they operate.  There has to be a voltage differential to produce the necessary current flow in the correct direction 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 problem with knockoffs, especially cheap knockoffs, is they often don’t support the energy requirements of the device, or aren’t built to maintain a steady flow safely.  Overall, it’s better to stick with the charger made 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 effectively use a charger that did not include your smart phone, notebook, camera, tablet, or other apparatus.  Make certain to follow what we said and you should be ready to go!
