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

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

Types of Chargers

In this article, we will concentrate 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 frequent.

Laptop chargers are fairly unique to the device they come with.  However, there may be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of the charger”head” and may 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 devices, and tablets.  Micro USB chargers typically have the same voltage, but may draw different amps.  I will explain this further later and how to know whether the charger is safe to use (depending on its recorded 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 notebook chargers are often specific to both make and model.  However, the plug fitting firmly is only one part of the equation.

Somewhere on 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 appears 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, in which 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 in the device, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V.  A charger must equal the voltage needed by the device.  This is important: drawing too high of a voltage could short out the device and possibly even start a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” to the device, or how much power is used by the device.  The amount of volts will never change, but the amount of amps that the system pulls may change depending 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 simultaneously. In order to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger that cannot support the amp requirement, it may burn out the power supply and kill the device.

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 (so long as the voltage is equal).  *Website Note: if you have an older device, it may not work with USB ports that employ 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 this: 5v +- 5%.  If this is true, 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 percent of 5v = 4.75 volts  OR  5v plus 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 equal 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 proper way 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.

The issue with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power requirements of the apparatus, or are not built to keep a steady flow safely.  This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stay with the charger designed for the device you’re using.

Now You Understand How to Safely & Effectively Swap Chargers

I hope this article was able to help you.  Now you know how to safely and efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Be sure to follow what we said and you should be good to go!
