Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet appear to come with their own charger. If you are like me, you’ve probably compiled a number of chargers over the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that is not the original manufacturer’s charger which came with the device?
Types of Chargers
In this article, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, 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 rather 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 might not be the best charging amperage or voltage for your device.
Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets. Micro USB chargers typically have the same voltage, but may draw different 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 with a 30-pin charge interface, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
In order for a charger to be used on a different 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 often specific to both make and model. However, the plug fitting securely is just one part of the equation.
Determined by the power brick of the charger you will get a tag 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 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 device, or just how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to approximately 5V, while a notebook 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 won’t ever change, but the quantity of amps that the device pulls may change depending on how hard the unit is working. The number that you locate on the battery that came with your device are the maximum amount of amps which can be pulled by the device. If a unit 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, tablet, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (so long as the voltage is equivalent ). *Website Note: if you have an older device, it might not work with USB ports that use the newest 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 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 device 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 (so long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).
An interesting thing to note is chargers supply a higher voltage than the batteries that they charge. That’s pretty much how they work. There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. When you look at your vehicle, it’s a 12V battery, but typical 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 often don’t support the energy requirements of the device, or aren’t built to keep a steady flow securely. Overall, it’s best to stay 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 come with your smart phone, notebook, camera, tabletcomputer, or other apparatus. Be certain you follow what we said and you should be ready to go!
