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

Every cell phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you’ve probably compiled a number of chargers through the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that is not the original manufacturer’s charger that came with the device?

Types of Chargers

In this article, we will 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 using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are rather unique to the device they come with.  However, there may be some generic chargers which boast the capability to be interchanged between notebooks.  This always requires changing of the charger”head” and may 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 apparatus, 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 whether the charger is safe to use (based on its listed amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, including 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 for use on another 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 so far as charging heads, while notebook chargers are often specific to both make and model.  However, the plug fitting securely is just 1 part of the equation.

How Voltage and Amperage Matter

Somewhere on the power brick of the charger you’ll find a label with the charger’s voltage (V) and amperage (A).  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 control, the voltage and amperage required will be found on the battery that came with the device or on the company’s website.

Voltage is how much power the charger will draw in the device, or how much is being”pushed” to the device 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 needed by the device.  This is important: drawing too high of a voltage could short out the device and potentially even start 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 quantity of volts won’t ever change, but the quantity of amps that the device 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 that may be pulled by the device.  The number 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 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 equivalent ).  *Website Note: if you have an older device, it may not work with USB interfaces that employ the newest 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 this: 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 thing to note is chargers provide a higher voltage than the batteries 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 way 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 issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the power requirements of the apparatus, or aren’t built to keep a steady flow securely.  Overall, it’s best to stay 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 help you.  Now you know how to safely and efficiently use a charger that did not come with your smart phone, laptop, camera, tablet, or other device.  Make sure you follow exactly what we said and you should be ready to go!
