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

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

Types of Chargers

In this guide, we’ll focus on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors.  Although some devices have chargers with a slightly different head or charging cable, these are the most common.

Laptop chargers are rather unique to the device they include.  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 may not be the optimal 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 exact same voltage, but may draw different 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 using a 30-pin charge port, a connector can be used to charge with the Lightning Connector.

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 as far as charging heads, whilst notebook chargers are often specific to both make and model.  However, the plug fitting securely is just one part of this equation.

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 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 seen 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 just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to around 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 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” to the device, or how much power is used by the device.  The amount of volts will never 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 are the max amount of amps which may be pulled from the device.  The number found on the charger is how many amps can be pulled simultaneously. In order to swap 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 which can’t support the amp necessity, it can burn out the power supply and kill the apparatus.

So if you have a modern USB device (smart phone, tabletcomputer, 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 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 recorded 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% of 5v = 5.25 volts. 

An interesting point to note is chargers provide a higher voltage than the batteries that they charge.  That’s pretty much how they work.  There needs to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery.  If you look at your car, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the power requirements of the apparatus, or are not built to keep 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 are 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 include your smart phone, notebook, camera, tablet, or other apparatus.  Be sure to follow what we said and you should be ready to go!
