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

Every cell phone, laptop, and tablet appear to come with their own charger.  If you are 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 isn’t the original manufacturer’s charger that 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, 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 fairly specific 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 to 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 various amps.  I’ll explain this further later and how to know whether the charger is safe to use (based on its recorded amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.

The Plugs Must Be The Same

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 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 1 part of this equation.

Determined by the power brick of the charger you’ll get a label with the charger’s voltage (V) and amperage (A).  For laptop 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 bottom 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 device, or how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to approximately 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 possibly even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” to the apparatus, 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 from the device.  The amount found on the charger is how many amps can be pulled simultaneously. 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 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 might 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 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 percent of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts. 

An interesting point to note is all chargers supply a higher voltage than the batteries they charge.  That’s 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.  When you look at your car, it has a 12V battery, but average 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 apparatus, or are not built to maintain a steady flow safely.  This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stick with the charger made for the device you’re 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 efficiently use a charger that did not come with your smart phone, notebook, camera, tablet, or other device.  Make certain to follow exactly what we said and you should be ready to go!
