Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem 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 isn’t the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, 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 specific to the device they come with. 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 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 same voltage, but may draw various 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 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 snugly to the charging port of the device. Micro USBs are the same across the board as far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting securely is just one part of the equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the charger you will 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 found at the base of the charger, where 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 how much is being”pushed” to the device by the charger. A phone will usually pull up to around 5V, while a laptop can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high of a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how quickly power is”pulled” into the device, or how much electricity is used by the device. The amount of volts won’t ever 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 are the maximum amount of amps that can be pulled from the device. The amount found on the charger is how many amps can be pulled simultaneously. If a unit is paired with a charger that cannot support the amp necessity, it can 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 equivalent ). *Website 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 may have their voltage recorded using 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 rating 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 chargers supply 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. When you look at your vehicle, 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 issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power needs of the apparatus, or aren’t built to maintain a steady flow safely. Overall, it’s better to stick with the charger made 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 effectively use a charger that did not come with your smart phone, notebook, camera, tabletcomputer, or other apparatus. Be certain to follow exactly what we said and you should be good to go!
