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

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

Types of Chargers

In this article, we will focus on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, 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 fairly specific to the device they include.  However, there may be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of this charger”head” and might not be the best charging amperage or voltage for 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 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).

For older devices using a 30-pin charge port, a connector can be used to charge with the Lightning Connector.

The Plugs Must Be The Same

For a charger to be used on another 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 1 part of this 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 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 bottom of the charger, where it would meet the wall.  For the device you are attempting to charge, 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 apparatus, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to around 5V, though a notebook can pull up to 25V.  A charger must equal the voltage needed by the device.  This is important: drawing too high 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 fast power is”pulled” to the device, or how much electricity is used by the device.  The amount of volts will never change, but the quantity of amps that the system pulls may change based on how hard the device is working.  The number that you find on the battery that came with your device will be the max amount of amps which can be pulled from the device.  The amount found on the charger is how many amps can be pulled simultaneously. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. 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 device.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (as long as the voltage is equivalent ).  *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 Is Not 5v…

Some devices might have their voltage recorded with a plus/minus on it like this: 5v +- 5%.  If this is true, 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 plus 5 percent of 5v = 5.25 volts. 

An interesting thing to note is all chargers supply a higher voltage than the batteries that they charge.  That is pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the correct way 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.

Stay Away From Cheap Knockoff Chargers

The problem with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the power requirements of the device, or aren’t built to maintain a steady flow securely.  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 designed for the device you are 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, laptop, camera, tabletcomputer, or other device.  Be sure you follow exactly what we said and you should be good to go!
