Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you are like me, you have probably compiled quite a few chargers over the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this guide, we will focus on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablet computers, 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 fairly unique to the device they include. However, there may be some generic chargers that boast the ability to be interchanged between notebooks. This always requires changing of this charger”head” and might not be the optimal 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 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 interface, a connector can be used to control the Lightning Connector.
In order 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 device. Micro USBs are the same across the board as far as charging heads, whilst laptop chargers are often specific to both make and model. However, the plug fitting firmly is just one part of this equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. 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 are trying to control, 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 apparatus, or how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” to the device, or how much power is used by the device. The quantity of volts will never change, but the quantity 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 will be the max amount of amps that may be pulled by the device. The amount found on the charger is how many amps can be pulled at once. If a unit is paired with a charger which can’t support the amp necessity, it may 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 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 Is Not 5v…
Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%. If this is true, you may use a charger rated at 4.75 to 5.25v because that rating 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. This means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equal to or higher than the device’s listed amperage).
An interesting thing to note is all 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 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.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy needs of the device, or are not built to maintain a steady flow securely. Overall, it’s better to stick with the charger made for the device you are using.
Now You Know 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, notebook, camera, tabletcomputer, or other apparatus. Be sure to follow what we said and you should be good to go!
