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

Every mobile phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you’ve 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 computer that is not the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this article, we will focus 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 common.

Laptop chargers are fairly unique to the device they come with.  However, there can be some generic chargers that boast the ability to be interchanged between notebooks.  This always requires changing of this charger”head” and may not be the optimal charging amperage or voltage for 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 various amps.  I’ll explain this further later and how to know whether the charger is safe to use (depending on its recorded amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices using a 30-pin charge interface, a connector can be used to control 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, while laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only one part of this equation.

How Voltage and Amperage Matter

Determined by 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 bottom of the charger, in which it would meet up with the wall.  For the device you are 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 apparatus, or just how much is being”pushed” to the device by the charger.  A phone will usually pull up to approximately 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 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” into the apparatus, or how much electricity is used by the device.  The quantity of volts will never change, but the amount of amps that the device 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 can be pulled by the device.  The number found on the charger is how many amps can be pulled at once. To be able to swap chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a device is paired with a charger that cannot support the amp requirement, it can burn out the power supply and kill the device.

So for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (so long as the voltage is equivalent ).  *Site Note: if you have an older device, it may not work with USB interfaces that use the new 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 true, you can 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% of 5v = 5.25 volts. 

An interesting thing to note is all chargers provide 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 way to charge the battery.  If 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 issue 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 safely.  This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better 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 assist you.  Now you know how to safely and effectively use a charger that did not include your smart phone, laptop, camera, tablet, or other device.  Make certain you follow exactly what we said and you should be good to go!
